Three home broadband deals: what 5G costs, what it does not guarantee and how it compares at your address
Three publishes both of its home broadband prices without a postcode, which most providers do not: £18 a month on a 24-month plan and £22 on a 12-month plan, each with unlimited data, an advertised average download speed of 150 Mbps and £0 to set up (checked 16 September 2026). Two things behind those numbers decide whether the deal is as good as it looks. The price already includes £5 a month off for paying by a recurring method, so it is £23 if you pay another way, and a fixed £3.50 goes on the bill each April, which takes the 24-month plan to £21.50 and then £25 and averages £21.50 a month across the term. This is a mobile signal to a hub rather than a line, so Three states in its own footnote that 'the speed that any individual premises will experience is not guaranteed, may vary'. One Touch Switch does not cover a move to 4G or 5G home broadband, so you cancel your old provider yourself and the two services overlap unless you time it. Compare it against every fixed line at your address at broadbandswitch.uk/compare/.

Every figure on this page carries the date it was checked. Three's prices, speeds and terms were read from three.co.uk on 16 September 2026, where Three publishes them without asking for a postcode; the fixed-line prices further down come from each provider's own site or our hand-checked deals table on the dates shown; the live comparison lower down is refreshed daily. Three home broadband is a mobile signal rather than a line, so what you get at your address is the thing to test rather than the thing to read.
What does Three home broadband cost right now?
Direct answer: Two prices, both published without a postcode: £18 a month on a 24-month plan and £22 on a 12-month plan, each carrying unlimited data, with no cap and no speed limit, an advertised average download speed of 150 Mbps and £0 to set up (checked 16 September 2026). The 24-month plan rises to £21.50 on 1 April 2027 and £25 on 1 April 2028, which averages £21.50 a month across the term.
Three is unusual in two ways here, and both are worth a moment. It publishes the price openly, where BT, Sky, Vodafone, TalkTalk and Plusnet make you hand over a postcode first, and it prints the whole price path on the plan card rather than burying the rise in the terms. What it does not print on the card is the condition attached to the headline: 'Your monthly charge includes a £5 discount for paying by a recurring method, such as Direct Debit'. Pay any other way and the plan is £23 a month, or £26.50 a month averaged across 24 months.
| Plan | Term | Now | From 1 April 2027 | From 1 April 2028 | Average over the term |
|---|---|---|---|---|---|
| Unlimited data, 24-month plan | 24 months | £18 | £21.50 | £25 | £21.50 £516 total |
| Unlimited data, 12-month plan | 12 months | £22 | £25.50 | n/a | £23.75 £285 total |
| 24-month plan, paying by any other method | 24 months | £23 | £5 a month more throughout | £5 a month more throughout | £26.50 |
What is included at that price
You get unlimited data, with no cap and no speed limit, £0 to set up, delivery next working day when you order before 8pm, up to 32 devices on the hub, a 30-day money-back guarantee, and no landline and no engineer visit at any point. New customers on the 24-month plan were also offered up to £300 towards the leaving fees on their old provider's final bill, on 24-month home broadband contracts only, claimed by sending your final bill within 90 days of your start date, and paid as account credit rather than cash.
What is not included is the thing a fixed line sells you: a promise about speed. Three's plan card advertises an average of 150 Mbps, and its own footnote explains the basis, which is that it applied to at least 50% of 5G Broadband customers inside 5G coverage areas between 8pm and 10pm, measured as of October 2025, and states that 'the speed that any individual premises will experience is not guaranteed, may vary'. That is not sharp practice, it is the physics of a radio link, but it changes what the price means.
For the arithmetic on any provider, our price and contract checker works out the real cost of a deal over its term, our price rises by provider page lists who raises what and when, and our 4G against 5G home broadband explainer covers which of the two you are likely to get.
What are you actually buying: a signal, not a line
Direct answer: A 4G or 5G connection from a nearby mast to a hub in your window, sold at one price whichever of the two reaches you. Nothing is dug, nothing is installed and nobody visits, which is why it can be online tomorrow; the trade is that Three cannot promise a speed, and says so in its own footnote: 'the speed that any individual premises will experience is not guaranteed, may vary'.
An average, not a floor
The advertised 150 Mbps applied to at least 50% of 5G Broadband customers inside 5G coverage areas between 8pm and 10pm, measured as of October 2025. Read that twice: it is a median-ish figure for half of 5G customers inside coverage at the busiest hours, and the measurement carries its own date, so it describes the network as it was, not as it is at your address tonight.
No guaranteed minimum
Three states that 'the speed that any individual premises will experience is not guaranteed, may vary', and lists the things that change it: the positioning of the hub, line of sight to your nearest mast, local topography, the number of users in your area and the thickness of walls and windows. A fixed-line provider prints a guaranteed minimum on your order and lets you leave if it misses. Three offers a 30-day money-back guarantee instead, which is a remedy you have to use rather than one that follows you through the contract.
Tied to your address
Three's terms describe a domestic service supplied for use in your home at the address you have provided, so this is not a service you take to a caravan or a second home; that is Three's separate mobile broadband product. The practical consequence is that the coverage check at your exact address, not your postcode, is the whole decision.
Three sells 4G or 5G to a hub, with no landline and no engineer, and which one you get depends on the coverage check rather than the plan you choose. Ofcom's Connected Nations update, Spring 2026, published 13 May 2026 on January 2026 data put outdoor 5G coverage between 76% and 94% of UK premises, depending on the operator, with 64% of UK premises covered by every operator and 5G standalone coverage between 49% and 85% of premises outdoors, across the three operators that have deployed it. In a town, 5G is likely; in a village, 4G is the realistic expectation, and 4G home broadband is a perfectly good connection for a light household but a different one from the headline. Our 5G home broadband and 4G home broadband pages compare the mobile-based options side by side.
The switching trap worth knowing before you order
One Touch Switch does not cover a move to 4G or 5G home broadband, so you cancel your old provider yourself and the two services overlap unless you time it. Three's own advice is to call your current provider first to find out your options for cancelling, then order. In practice the safe order of events is: order the hub, test it hard for a few days at the hours you care about, then give notice on the old line. That means a short overlap and two bills for a week or two, which is a price worth paying for not being stranded if the signal disappoints.
One more practical point about a radio link: where it lands in the house matters more than anything you can buy. The hub belongs in the window facing the mast, not in a cupboard, and for a stubborn address Three sells an Outdoor Hub, an externally mounted 5G receiver paired with an eero router, at £18 a month. Our router placement guide and RouterMap help with the indoor half of the problem, and our speed test is the way to check what you are actually getting once the hub arrives.
The rise Three does fix, and why it bites harder here
Direct answer: Three raises the price by a fixed £3.50 a month each April, written into the contract and printed on the plan card as dated steps: £18 now, £21.50 from 1 April 2027 and £25 from 1 April 2028. In pounds that is close to the market norm. As a share of the bill it is the steepest on this site, because £3.50 is around 19% of a £18 plan.
Since 17 January 2025 Ofcom has banned in-contract rises linked to inflation and required any rise to be stated in pounds and pence before you buy. Three complies in the clearest way we have seen: the plan card itself carries the steps, so there is nothing to work out. Its footnote reads 'Each April, your Monthly Charge will increase by a fixed amount depending on your plan's data allowance. All Home Broadband plans will increase by £3.50 per month'. The point worth making is the arithmetic nobody prints. A fixed £3.50 on a £18 plan is a far bigger proportional increase than £4 on BT's £29.99 or £4 on Virgin Media's £23.99, so the cheapest headline on the market converges towards the middle of it by the second year. That is why the column that matters on this page is the average across the term rather than the price today. Our guide to in-contract price rises sets out the rules, and price rises by provider lists every provider's amount.
£18 to £25
Three prints the dated steps before you buy, so the 24-month plan costs £516 in total, or £21.50 a month averaged out. Nothing here is a surprise, which is more than most providers manage.
Who raises what
£3.50 at Three, £4 at BT, £4 at EE, £4 at Plusnet, £4 at TalkTalk, £4 at Virgin Media and £3.50 at Vodafone, all fixed in the contract. Sky and NOW fix no amount at all and give notice instead.
Older contracts differ
Three's home broadband terms for customers who joined from 8 September 2024 set the annual increase at £2 a month, against £3.50 on the plans sold today. If you are already a customer, the amount in your own terms is the one that applies, not the one on the current plan card.
What VodafoneThree means for this product
Direct answer: Three is part of VodafoneThree, the joint venture with Vodafone UK completed on 31 May 2025, and the group has announced this: 'Over the next 12 months, VodafoneThree will bring Three's mobile broadband (Fixed Wireless Access) together with Vodafone's Full Fibre into one home broadband portfolio, under the Vodafone brand'. On 16 September 2026, Three was still selling Home Broadband under its own name, on its own site, when we checked. For a buyer, the network is the good news and the brand is the open question: your contract terms travel with you if the badge changes, but the badge may well change inside a 24-month term.
The network side is straightforward and positive. Three now runs on the Nation's Network, the combined Vodafone and Three network, backed by an £11bn investment plan. Vodafone and Three customers can now automatically use each other's networks at no extra cost, and the group has committed to 99.95% 5G Standalone population coverage by 2034, with 90% targeted by the third year. A fixed wireless service lives or dies on mast density, so more sites and a second operator's grid is exactly the investment that helps this product. One caution on how far to read that: Three states the roaming benefit for customers, and does not say a Home Broadband hub roams onto Vodafone sites, so treat the coverage check at your address as the test rather than assuming the combined footprint.
The brand side is the part worth a thought before you sign for two years. VodafoneThree said in its own announcement that Vodafone would be the converged brand, and that Three's fixed wireless and Vodafone's full fibre would be brought into one home broadband portfolio under the Vodafone name. That plan was announced on 12 June 2025 with a 12-month horizon, and Three was still selling Home Broadband under its own name when we checked. Nothing about a brand change alters the contract you signed, the price steps printed on your plan card or your right to leave under it, and a service moving from one brand to another inside the same group is not a reason to avoid a good deal. It is a reason to keep your paperwork. Our Vodafone page covers the full fibre half of that portfolio, and our Great Consolidation report tracks who is buying whom across the UK market.
Three against a fixed line at your address
Direct answer: On price, Three usually wins the headline and often wins the term: £18 a month, averaging £21.50 across 24 months, against £25.82 for Plusnet's entry full fibre, £26 for Sky's, £26 for NOW's, £27.50 for Vodafone's, £29 for TalkTalk's and £31.24 for EE's. What the extra buys on a fixed line is a guaranteed minimum speed, a right to leave if it is missed, and a connection that does not care how many neighbours are streaming.
| Provider | What it is | Entry price | Average over 24 months | Speed promise | Set-up |
|---|---|---|---|---|---|
| Three | 4G or 5G to a hub | £18 (checked 16 September 2026) | £21.50 | No guaranteed minimum; 30-day money-back guarantee instead | £0 |
| Plusnet | Full fibre, Openreach | from £20.99 (our comparison, 16 September 2026) | £25.82 | Guaranteed minimum on your order | £9.99 |
| Sky | Full fibre, Openreach or CityFibre | £23 (checked 15 September 2026) | £26 | Guaranteed minimum with an exit right | £0 |
| NOW | Full fibre, Openreach or CityFibre | £23 (checked 16 September 2026) | £26 | Sky's guarantee, with an exit right | £0 activation fee and £0 delivery fee |
| Vodafone | Full fibre, Openreach or CityFibre | £24 (our comparison, 1 September 2026) | £27.50 | Guaranteed minimum on your order | £0 |
| Virgin Media | Cable | £23.99 (M125, checked 15 September 2026) | £27.99 | Guaranteed minimum on your order | £0 |
| EE | Full fibre, Openreach | £25.99 (checked 16 September 2026) | £31.24 | Speed Guarantee with an exit right | £30 |
| BT | Full fibre, Openreach | £29.99 (checked 15 September 2026) | £34.41 | Guaranteed minimum with an exit right | £10 |
Two honest conclusions. Three is the cheapest of these over two years, and by enough to matter to a tight budget: the gap to the nearest full fibre entry price is real money across 24 months. And every one of the others sells you something Three cannot, which is a number it has to hit. Which way that trade falls depends on the address, not the brand. Where full fibre has arrived, the premium is small and the certainty is worth it for most working households; Ofcom's Spring 2026 data puts full fibre availability at 82% of UK premises and gigabit-capable availability at 89%. Where it has not, or where the tenancy is short, Three is often the best answer on this page. When we last hand-checked every deal, on 1 September 2026, the 373 broadband-only deals from the 28 providers we compare started at £13.50 a month (4th Utility, 150 Mbps on CityFibre), with good full fibre clustering between £23 and £34 a month.
Put Three next to every fixed line at your address
Enter your postcode and our comparison lists every provider we can switch you to, on every network that reaches you, lowest price first, so you can see exactly what the fixed-line premium is where you live.
Compare at my postcode →What does Three give you, and what does it leave out?
Direct answer: A hub matched to the coverage at your address, unlimited data, with no cap and no speed limit, £0 to set up with delivery next working day when you order before 8pm, up to 32 devices connected, a 30-day money-back guarantee and up to £300 towards your old provider's leaving fees; what it leaves out is a guaranteed speed, a landline, a television bundle, a social tariff and any way to take the service with you.
Each item below was checked against Three's own pages and terms on 16 September 2026.
A hub, chosen by your coverage
You get a 4G hub, a 5G hub, an Outdoor Hub for weaker indoor signal, and eero mesh Wi-Fi. The model is not contractual: 'Actual product may vary. We may send you a different hub with the same or better specification, depending on stock availability.'. When you leave, the 5G Hub must go back, while 4G hubs and eero devices do not.
Unlimited, on both terms
Three sells unlimited data, with no cap and no speed limit on both the 12-month and the 24-month plan, which makes it a reasonable answer for a heavy streaming household as long as the signal holds up. Three's terms do allow traffic management to protect the network, as every mobile network's terms do.
£0 to set up
No activation fee and no engineer, with delivery next working day when you order before 8pm. Against a fixed line's usual £10 to £30 activation and a wait of one to three weeks, that is the strongest practical argument for this product: you can be online tomorrow.
A 30-day money-back guarantee
This is the safety net that makes ordering low risk, and the reason to test hard in the first fortnight. It is a remedy you have to use inside the window, so put a date in the diary when the hub arrives rather than waiting to see whether the evenings improve.
Help with your exit fees
Three advertised up to £300 towards the leaving fees on your old provider's final bill, on 24-month home broadband contracts only, claimed by sending your final bill within 90 days of your start date, and paid as account credit rather than cash. It reduces what you pay Three rather than refunding what your old provider charged you, so count it as a discount on the new deal.
No social tariff
Three runs no broadband social tariff, and Ofcom's list of social tariffs does not include it. The sister brands inside VodafoneThree run mobile social tariffs, SMARTY, the VodafoneThree sub-brand, at £12 a month and VOXI For Now at £10 a month, both mobile rather than home broadband, and several fixed-line providers run broadband ones from £12.50 a month, which is the comparison a household on a qualifying benefit should make first.
One thing to set straight, because it circulates widely: Three's home broadband is not a rolling monthly product today. The plans advertised on the checked date ran for 12 or 24 months, and leaving needs 30 days' notice either way, with an early cancellation fee inside the term worked out as the monthly charges left in the minimum term, less a discount currently 3%. Three's own pages have not caught up with that, so look at the order page before you assume either way: Three's own broadband landing page still says '1-month or 24-month contracts' while the Home Broadband plans page advertises 12 and 24 months.
Who should choose Three, and who should not?
Direct answer: Choose Three if the coverage check is strong and you want the cheapest credible connection, if you need to be online this week, if you are in a short tenancy or a flat that full fibre has not reached, or if a landline and an engineer visit are things you would rather avoid; look elsewhere if you need a guaranteed minimum speed, if you work on video calls at peak hours, if your household qualifies for a social tariff, or if full fibre at your address costs only two or three pounds more.
Take Three when
One or more of these applies to your household
- The coverage check at your exact address is strong, and you are willing to test it properly inside the 30-day money-back guarantee
- You need a connection quickly: £0 to set up and delivery next working day when you order before 8pm, against one to three weeks for a fixed line
- You are in a short tenancy or a student let, where 12 or 24 months and no engineer visit beat a two-year line install
- Full fibre has not reached your address, and the alternative is an old copper line at a similar price
- Price is the deciding factor: £18 now, averaging £21.50 across the term, is the cheapest on this page
- You are leaving a contract early and the up to £300 towards leaving fees covers the exit charge
A fixed line is the better buy when
Three's model does not suit you
- You need a speed you can rely on: Three states that 'the speed that any individual premises will experience is not guaranteed, may vary', while every fixed-line provider here prints a guaranteed minimum
- You work from home on video calls, or the household games competitively, and evening congestion would cost you real money
- Someone in the household receives a qualifying benefit: Three runs no broadband social tariff, and Ofcom's list of social tariffs does not include it, while fixed-line social tariffs start at £12.50
- Full fibre is available and close on price: the gap to Plusnet at £25.82 or Sky at £26 over 24 months is often smaller than people expect
- You want a landline number, a television bundle or mesh Wi-Fi included rather than added
- You want the switch handled for you: One Touch Switch does not cover a move to 4G or 5G home broadband, so you cancel your old provider yourself and the two services overlap unless you time it
The honest test is not which product is better in general, because a fixed line is, but which is better at your address for your money. Run the postcode, look at the gap, and decide whether the certainty is worth it.
Why Three has no broadband complaints figure
Direct answer: Because this is not a fixed line. Three has no fixed broadband complaints figure at all, because Ofcom's broadband table covers fixed-line services and Three's home broadband runs on its mobile network. The nearest read is the mobile table, where Three recorded 2 complaints per 100,000 pay monthly customers in Q1 2026 against an industry average of 2, up from 1 per 100,000 in Q4 2025, level with Tesco Mobile and behind EE, giffgaff and Vodafone on 1.
| Provider | Complaints per 100,000 |
|---|---|
| Plusnet | 4 |
| Sky | 5 |
| Virgin Media | 6 |
| EE | 6 |
| Industry average | 6 |
| BT | 7 |
| Vodafone | 8 |
| TalkTalk | 10 |
| Three | no fixed broadband complaints figure at all, because Ofcom's broadband table covers fixed-line services and Three's home broadband runs on its mobile network |
Be careful what you conclude from that. An absence is not a good record or a bad one, it is a measurement that does not exist, and it removes one of the checks you would normally run before handing a provider two years. Three's mobile figure of 2 per 100,000 is a solid result and it covers the network this broadband runs on, which makes it the most relevant number available, but it counts complaints about phone contracts rather than about a hub in a window. On Trustpilot, Three UK stood at 4.6 out of 5 from 68,194 reviews on 16 September 2026, on a profile that mixes mobile, retail and broadband, so treat it as context rather than proof. Our Complaints Floor report explains how much of the UK market now sits outside Ofcom's tables altogether.
If something does go wrong, the route is clearer than the data. Three's dispute scheme is CISAS, and the rules changed on 8 April 2026: an unresolved complaint can go free of charge to the scheme after six weeks, down from eight. Our complaints and your rights guide walks through the steps, and our complaints page has the contacts.
What should you check before you order Three?
Direct answer: Six checks, five minutes: the coverage at the exact address, the real monthly price once the payment discount and the April rise are counted, the overlap you will need because One Touch Switch does not cover this, a proper test inside the money-back window, where the hub will physically sit, and the exit and hub return terms.
Six-step Three home broadband check
Run each before you commit to a contract.
Run Three's coverage check on the exact address, not the postcode
A postcode can cover a street where one end has 5G and the other has none. Check the address, note whether the answer is 4G or 5G, and treat a marginal result as a reason to plan the test rather than a reason to avoid the deal.
Work out the real monthly price before you compare
The advertised £18 assumes a recurring payment: 'Your monthly charge includes a £5 discount for paying by a recurring method, such as Direct Debit'. Pay another way and it is £23. Then add the fixed rise: the plan reaches £21.50 and £25, and averages £21.50 across the term.
Order before you cancel, and expect an overlap
One Touch Switch does not cover a move to 4G or 5G home broadband, so you cancel your old provider yourself and the two services overlap unless you time it. Get the hub, test it, then give your old provider notice, and accept a week or two of paying twice rather than a gap with no connection at all.
Test hard inside the guarantee window
The 30-day money-back guarantee is the real product test. Use the connection at the hours you care about, especially between 8pm and 10pm, which is the window Three's own speed measurement uses, and run a speed test on more than one evening before the window closes.
Put the hub where the signal is, not where the socket is
Line of sight to the mast is the biggest single factor Three lists, alongside the positioning of the hub, line of sight to your nearest mast, local topography, the number of users in your area and the thickness of walls and windows. A window on the right side of the house can double what you get, and for a stubborn address Three sells an Outdoor Hub, an externally mounted 5G receiver paired with an eero router, at £18 a month.
Check the exit terms and the hub return
Inside the term the fee is the monthly charges left in the minimum term, less a discount currently 3%, and leaving needs 30 days' notice. When you do leave, the 5G Hub must go back, while 4G hubs and eero devices do not, with a non-return charge if it does not come back.

How much is Three home broadband a month?
Three publishes both prices openly, without asking for a postcode first. On 16 September 2026 they were £18 a month on a 24-month plan and £22 a month on a 12-month plan, both carrying unlimited data, with no cap and no speed limit, with an advertised average download speed of 150 Mbps, with £0 to set up and delivery next working day when you order before 8pm. Two adjustments matter before you compare that with anything else. The advertised price includes £5 a month off for paying by a recurring method, so it is £23 if you do not, and the fixed April rise takes the 24-month plan to £21.50 and then £25, which averages £21.50 a month over the term.
Does Three put its prices up during the contract?
Yes, by a fixed amount printed on the plan card before you buy. Three's footnote reads 'Each April, your Monthly Charge will increase by a fixed amount depending on your plan's data allowance. All Home Broadband plans will increase by £3.50 per month', and the 24-month card shows the dated steps: £18 now, £21.50 from 1 April 2027 and £25 from 1 April 2028. That is the same pounds-and-pence model Ofcom has required since 17 January 2025, and it is easy to plan around. The catch is proportion rather than principle: £3.50 is about 19% of a £18 plan, where the same sort of rise on a £30 fixed-line deal is nearer an eighth. Older Three contracts can carry a different amount: the terms for customers who joined from 8 September 2024 set the annual increase at £2 a month, so check your own paperwork rather than assuming today's figure.
Is Three home broadband any good, and what is the catch?
For the right address it is one of the cheapest ways to get a household online, with no engineer, no landline and a hub that works the day it arrives. The catch is written in Three's own footnote: 'the speed that any individual premises will experience is not guaranteed, may vary'. The advertised 150 Mbps is an average that applied to at least 50% of 5G Broadband customers inside 5G coverage areas between 8pm and 10pm, measured as of October 2025, and what you get depends on the positioning of the hub, line of sight to your nearest mast, local topography, the number of users in your area and the thickness of walls and windows. A fixed line gives you a guaranteed minimum speed and a right to leave if it is not met; Three gives you a 30-day money-back guarantee instead, which is a real protection but a different one, because you have to notice and act inside the window.
Is Three home broadband 4G or 5G?
Either, depending on what reaches your address, and the price is the same for both: Three sells 4G or 5G to a hub, with no landline and no engineer. Which hub you are sent depends on the coverage check, and Three reserves the right to vary the model: 'Actual product may vary. We may send you a different hub with the same or better specification, depending on stock availability.'. Ofcom's Connected Nations update, Spring 2026, published 13 May 2026 on January 2026 data put outdoor 5G coverage between 76% and 94% of UK premises, depending on the operator, with 64% of premises covered by every operator, so a 5G postcode is likely in a town and much less likely in the countryside. Three's own coverage checker is the only test that counts for your address, and the 30-day money-back guarantee is what protects you if the check is optimistic.
Is there a set-up fee or an upfront cost with Three?
No set-up fee was charged on the checked date: Three advertised £0 to set up, with delivery next working day when you order before 8pm. That is genuinely different from most fixed-line providers, where an activation fee of £10 to £30 is normal, and it is part of why the headline looks so low. The cost that is easy to miss is the recurring payment discount: 'Your monthly charge includes a £5 discount for paying by a recurring method, such as Direct Debit', so a household paying another way pays £23 a month rather than £18, which works out at £26.50 a month across 24 months.
Can I switch to Three home broadband under One Touch Switch?
No, and this is the single most common surprise with any 4G or 5G home broadband. One Touch Switch does not cover a move to 4G or 5G home broadband, so you cancel your old provider yourself and the two services overlap unless you time it. Three's own advice is to call your current provider first to find out your options for cancelling, then order. Plan for a short overlap rather than a clean handover: order the hub, check it works at your address, then give your old provider notice, and expect to pay both for a few days. Our switching guide sets out the process and what One Touch Switch does and does not cover.
Does Three pay my exit fees if I am still in contract?
It offers to, up to a limit. Three advertised up to £300 towards the leaving fees on your old provider's final bill on 16 September 2026, on 24-month home broadband contracts only, claimed by sending your final bill within 90 days of your start date, and paid as account credit rather than cash. Read that carefully before you rely on it: it is credit on your Three account rather than money back, it applies to the 24-month plan and not the shorter one, and the claim has a deadline. Our guide to switching credit lists which providers pay what and how to claim it.
What router does Three give you, and do I have to send it back?
You get a 4G hub, a 5G hub, an Outdoor Hub for weaker indoor signal, and eero mesh Wi-Fi depending on coverage and what you order. When you leave, the 5G Hub must go back, while 4G hubs and eero devices do not, and Three charges a non-return fee if the 5G Hub does not come back. For a home where the signal indoors is poor, Three sells an Outdoor Hub, an externally mounted 5G receiver paired with an eero router, at £18 a month on 24 months on the checked date, which is the same price as the indoor plan.
Can I take the Three hub with me, or use it at another address?
Not as a home broadband service. Three's terms describe it as a domestic service supplied for use in your home at the address you have provided, so the hub is meant for the address on the account rather than a caravan, a second home or a holiday. If what you want is broadband that travels, Three sells mobile broadband separately as a pocket hub or a data SIM, which is a different product with different prices. Moving home is worth a call before you move, not after.
How long is the Three contract, and how do I leave?
The plans advertised on 16 September 2026 ran for 12 or 24 months, and leaving needs 30 days' notice either way. Inside the minimum term you pay an early cancellation fee, which Three calculates as the monthly charges left in the minimum term, less a discount currently 3%. Outside it, give the same notice and return the hub. One oddity worth knowing about: Three's own broadband landing page still says '1-month or 24-month contracts' while the Home Broadband plans page advertises 12 and 24 months, so if a one-month plan matters to you, check what the order page actually offers on the day.
Does Three have a broadband social tariff?
No. Three runs no broadband social tariff, and Ofcom's list of social tariffs does not include it. That is a real gap next to the fixed-line providers, where Virgin Media Essential Broadband costs £12.50, BT Home Essentials starts at £16.50, Vodafone Essentials Broadband costs £20 and NOW Broadband Basics costs £20 a month. Two sister brands inside VodafoneThree do run mobile social tariffs, SMARTY, the VodafoneThree sub-brand, at £12 a month and VOXI For Now at £10 a month, both mobile rather than home broadband, which help with a phone bill rather than a home connection. If someone in the household receives a qualifying benefit, our social tariffs guide lists every tariff worth checking before you sign anything here.
How many complaints does Three get about its broadband?
Ofcom does not say, because Three has no fixed broadband complaints figure at all, because Ofcom's broadband table covers fixed-line services and Three's home broadband runs on its mobile network. The nearest available read is its mobile record, and that is the network this broadband runs on: Three recorded 2 complaints per 100,000 pay monthly mobile customers in Q1 2026 against an industry average of 2, up from 1 per 100,000 in Q4 2025, level with Tesco Mobile and behind EE, giffgaff and Vodafone on 1. On Trustpilot, Three UK's whole profile stood at 4.6 out of 5 from 68,194 reviews on 16 September 2026, which mixes mobile, in-store and broadband experience rather than measuring broadband alone. If you do need to complain, Three's scheme is CISAS, and an unresolved complaint can go there free of charge after six weeks.
What does the VodafoneThree merger mean for Three broadband customers?
It means the network is getting bigger and the brand may not survive in this product. Three is part of VodafoneThree, the joint venture with Vodafone UK completed on 31 May 2025, the two networks are being combined into the Nation's Network, the combined Vodafone and Three network, backed by an £11bn investment plan, and Vodafone and Three customers can now automatically use each other's networks at no extra cost. At the same time the group announced this: 'Over the next 12 months, VodafoneThree will bring Three's mobile broadband (Fixed Wireless Access) together with Vodafone's Full Fibre into one home broadband portfolio, under the Vodafone brand'. On 16 September 2026, Three was still selling Home Broadband under its own name, on its own site, when we checked. Nothing about that changes a contract you have already signed, and your terms travel with you if the brand changes, but it is worth knowing before you commit to 24 months that the badge on your bill may change during it.
Is Three cheaper than fixed-line broadband?
On the headline, usually yes. Three's £18 was below the entry price of every fixed-line provider we track on the same dates, and it averages £21.50 over the term against £25.82 for Plusnet's cheapest full fibre, £26 for Sky's, £26 for NOW's and £31.24 for EE's. What you give up for the gap is the guarantee: a fixed line commits to a minimum speed and lets you leave if it misses, while Three commits to an average and gives you 30-day money-back guarantee. If full fibre reaches your address and you use the connection for work, the extra two or three pounds a month usually buys more than it costs. If it does not reach you, or you are in a short tenancy, Three is often the best answer on the page.
In short
- Three publishes both home broadband prices without a postcode: £18 a month on 24 months and £22 on 12 months, each carrying unlimited data, with no cap and no speed limit, an advertised average of 150 Mbps and £0 to set up (checked 16 September 2026).
- The advertised price includes £5 a month off for paying by a recurring method, so it is £23 otherwise, and a fixed £3.50 goes on each April, taking the 24-month plan to £21.50 and then £25, an average of £21.50 a month.
- This is a signal rather than a line: Three states that 'the speed that any individual premises will experience is not guaranteed, may vary', and the 150 Mbps average applied to at least 50% of 5G Broadband customers inside 5G coverage areas between 8pm and 10pm, measured as of October 2025, and the protection on offer is a 30-day money-back guarantee rather than a guaranteed minimum speed.
- One Touch Switch does not cover a move to 4G or 5G home broadband, so you cancel your old provider yourself and the two services overlap unless you time it, so the move needs planning; against that, Three advertised up to £300 towards your old provider's leaving fees on 24-month home broadband contracts only, claimed by sending your final bill within 90 days of your start date, and paid as account credit rather than cash.
- Three runs no broadband social tariff, and Ofcom has no fixed broadband complaints figure at all, because Ofcom's broadband table covers fixed-line services and Three's home broadband runs on its mobile network; its mobile record for Q1 2026 was 2 complaints per 100,000 against an average of 2.
- Three is part of VodafoneThree, the joint venture with Vodafone UK completed on 31 May 2025, and the group has announced that 'Over the next 12 months, VodafoneThree will bring Three's mobile broadband (Fixed Wireless Access) together with Vodafone's Full Fibre into one home broadband portfolio, under the Vodafone brand'; on 16 September 2026, Three was still selling Home Broadband under its own name, on its own site, when we checked.

Social tariffs: the gap in Three's range
Direct answer: Three runs no broadband social tariff, and Ofcom's list of social tariffs does not include it; that list was updated 17 August 2026. Two VodafoneThree sister brands do run mobile ones, SMARTY, the VodafoneThree sub-brand, at £12 a month and VOXI For Now at £10 a month, both mobile rather than home broadband, but those help with a phone bill rather than a home connection.
For a household on a qualifying benefit this is the single most valuable check on the page, because a social tariff usually beats every headline deal and carries no minimum term. On the fixed-line side, Virgin Media Essential Broadband costs £12.50, BT Home Essentials starts at £16.50, Vodafone Essentials Broadband costs £20 and is open to new customers, NOW Broadband Basics costs £20 a month, and Sky Broadband Basics costs £20 for existing Sky customers. Our deals check of 1 September 2026 listed social tariffs from £12.50 a month across the providers we compare. Our social tariffs guide lists every tariff, the benefits that qualify and how to apply, and our insight on how social tariff broadband works covers the steps.
If no social tariff is available at your address, or nobody in the household qualifies, Three's £18 is a reasonable fallback and beats most standard fixed-line entry prices. Check the coverage first, and keep the 30-day money-back guarantee in mind as the way out if the signal disappoints.
