BT vs TalkTalk broadband: the same Openreach line, and the tier where the budget one stops being cheaper

Which one to choose

Direct answer: BT, unless you want the entry tier and only the entry tier. At 500 Mbps on the same Openreach line the two are under ten pounds apart across the whole of 24 months, and TalkTalk's published upload at that tier is the higher of the two. The budget provider is not meaningfully the cheaper one at the speed most households buy, so the price is not what you are choosing between. At the bottom of the ladder TalkTalk is genuinely cheaper, by £149.76 over the term, and BT gives twice the download speed for the difference.

That is the answer, and the rest of this page is the working. It is worth saying at the top that this is a narrower choice than the advertising on either side suggests. Both run over the same Openreach line to the same house, so the cable in the ground is not what you are choosing between. The speed, the reliability and the engineer are Openreach's on both. What you are actually choosing is a price, a contract and a customer service department.

Two things push the decision away from price, and both are about what you can find out rather than what you pay. BT prints six prices, each with the next two years beside it, and a download speed, an upload speed and a guaranteed minimum speed on every card. TalkTalk prints one price and two upload figures. And The thing neither price list mentions is who you will be buying from in month 24. Neither is a reason to rule TalkTalk out. None of that makes TalkTalk a bad buy, and none of it is insolvency. TalkTalk is trading, it has new funding in place, both transfers so far kept the price and the terms, and the companies taking the customers are real operators.

The same line, and what that settles

Direct answer: Both run over the same Openreach line to the same house, so the cable in the ground is not what you are choosing between. The speed, the reliability and the engineer are Openreach's on both. What you are actually choosing is a price, a contract and a customer service department. The same fibre reaches 23.4 million premises as at 30 June 2026, and a dozen retailers sell over it besides these two.

This is the part of a head-to-head worth getting out of the way first, because it removes most of the arguments people expect to have. On an Openreach full fibre line the glass in the ground, the electronics in the cabinet and the engineer who turns up are Openreach's, not BT's and not TalkTalk's, and Openreach is obliged to sell to every retailer on the same terms. So the connection is not the variable. Speed claims that differ between them at the same tier are a difference in how the two describe the same product.

There is one wrinkle on TalkTalk's side and it is not cosmetic. TalkTalk sells the same tiers over Openreach and over CityFibre at the same price, and publishes no way to tell which you would get short of checking a postcode. Two households on the same TalkTalk tariff, paying the same price, can be on two different networks, and it changes a right rather than just a technology. Ofcom's automatic compensation scheme, which pays out when a repair runs late or an engineer misses an appointment, treats TalkTalk's non-Openreach customers differently, and the safety nets section below has the detail. BT sells over Openreach only, so nothing equivalent applies to it.

Our guide to full fibre from every network covers who builds what, and the availability checker tells you which networks reach your address.

What each one costs today

Direct answer: BT advertises six packages, from £26.99 for Fibre Essential to £31.99 for Full Fibre 900. TalkTalk advertises one price publicly, £25 a month, with the tiers behind a postcode. Both raise the price by £4 a year in contract and both print the resulting figures before you sign.

Look at the bottom of each ladder and the picture reverses, which is why the tier matters more than the brand. TalkTalk's entry full fibre totals £696 over the term against £845.76 for BT's cheapest full fibre, a difference of £149.76. At the entry tier TalkTalk is genuinely cheaper, and BT gives twice the download speed for the difference. Whether that is good value depends entirely on whether you would use the speed.

Two oddities on the ladders, one on each side. Full Fibre 300 and Full Fibre 500 cost the same £29.99 a month, and Full Fibre 300 charges £20 more in the first month, so Full Fibre 300 is never the better buy at an address that can take both. And on TalkTalk's, Full Fibre 150 was £1 cheaper than the slower Full Fibre 65, so the entry speed is not the entry price, and the CityFibre and Openreach versions of each plan carried the same monthly price but different gift cards. Neither is a trick; both are what happens when a price list is built around what an address can take rather than around a neat ladder. But where both tiers are available, the faster one is the cheaper one, and that is worth knowing before you click the first button you see.

On set-up TalkTalk wins outright. BT's activation is £10, cut from £30 and shown on the price list as a saving. TalkTalk charges £0 on its full fibre packages. Offers move faster than prices and both companies run them, so check the current one at your own address before you decide; neither page had a dated, verifiable offer when we read it.

Our price and contract checker totals any deal across its term, our hand-checked deals table carries every figure with the date it was verified, and our TalkTalk review carries the tier prices with their own dates.

What each one lets you check before you sign

Direct answer: BT prints six prices, each with the next two years beside it, and a download speed, an upload speed and a guaranteed minimum speed on every card. TalkTalk prints one price and two upload figures. TalkTalk's public deals page carries one price, from £25 a month, and puts every tier price behind a postcode check. TalkTalk publishes an upload speed for two of its tiers and does it on a page about gaming: 110 Mbps on Full Fibre 900 and 75 Mbps on Full Fibre 500. TalkTalk publishes a guaranteed minimum speed for one tier, 725 Mbps on Full Fibre 900, and says the rest are shown once you check availability.

Once the price stops separating two providers, the next honest question is how much of the deal you can see before you commit to it, and on this pairing the answer is lopsided. Open BT's deals page and every plan carries six things: a monthly price, a price from 31 March 2027, a price from 31 March 2028, an average download speed, an average upload speed and a guaranteed minimum download speed. You can total the whole commitment and compare it against anything else without entering a postcode or an email address.

Open TalkTalk's and you get one price, the two future prices beside it, and an invitation to check your area. We went looking for the rest on TalkTalk's own site: the tier pages, the full fibre hub, the speed page. TalkTalk publishes an upload speed for two of its tiers and does it on a page about gaming: 110 Mbps on Full Fibre 900 and 75 Mbps on Full Fibre 500. TalkTalk publishes a guaranteed minimum speed for one tier, 725 Mbps on Full Fibre 900, and says the rest are shown once you check availability.

Our guide to minimum guaranteed speeds explains what each provider's figure is worth, and upload against download speed covers which of the two actually limits what you are doing.

What 24 months actually costs

Direct answer: At the 500 Mbps tier, £825.76 for BT against £816 for TalkTalk: a difference of £9.76 across the whole term, or £0.41 a month. TalkTalk's published upload at that tier is 75 Mbps against BT's 73 Mbps.

Both sums are built the same way, from each provider's own published prices and its own contractual rise: six months at the opening price, twelve at the first increase, six at the second. Neither is an estimate. BT's activation fee is in its column and TalkTalk charges none, which is most of the remaining gap.

Now do the same sum at the top of each ladder, because that is where the budget label stops being wrong and starts being backwards. BT Full Fibre 900 totals £873.76 across the term. TalkTalk Full Fibre 900 totals £960. That is £86.24 more for TalkTalk, for the same 900 Mbps, the same published upload of 110 Mbps on both, and the same Openreach line. At the top of the market the budget provider is the dearer one.

Do it at the bottom and TalkTalk wins properly: £696 against £845.76, which is £149.76 across the term, though BT's cheapest full fibre tier is twice the speed of TalkTalk's. TalkTalk is cheaper at the entry tier, level at 500 Mbps and dearer at 900, so the budget label is true at one end of the ladder and wrong at the other.

So there is a real price argument for TalkTalk and it lives at one end of the ladder. If the entry tier is what you want, take it. If you want the speed most households now buy, you are not choosing on price, and everything below this section is what you are choosing on instead.

Our price and contract checker does this sum for any deal and any start month, and the cheapest deals ranks the whole market on the average across a term rather than on the headline.

Who you will be buying from in month 24

Direct answer: The thing neither price list mentions is who you will be buying from in month 24. TalkTalk Group said on 2 March 2026: “As previously announced, the Group has appointed advisers in response to inbound interest from potential acquirers of parts of the group. A formal process to explore disposal options is underway.” Since then two customer bases have moved to other companies, on the same price and the same terms. None of that makes TalkTalk a bad buy, and none of it is insolvency. TalkTalk is trading, it has new funding in place, both transfers so far kept the price and the terms, and the companies taking the customers are real operators.

We would not normally put a company's corporate arrangements in a price comparison, because most of them tell a household nothing. This one is different, for a specific reason: two groups of TalkTalk customers have already found out that the company they signed with is not the company that bills them, and TalkTalk's own help centre is where it is written down. The sentence to those customers reads: “Your broadband contract transferred to Rise Fibre on 1 August 2026.”

The terms carried across intact, and that is the important half. TalkTalk's own wording is that “Your existing contract and any remaining minimum term will continue to apply following the transfer to Rise Fibre.” and that “No changes are being made to your monthly broadband charge because of the transfer.” A further 13,500 broadband and phone customers moved to Fleur Telecom on 1 September 2026, on the same terms: same package, same price, same network. Both acquirers are real operators and both said the service would not change. Nobody was cut off, nobody was repriced, and nothing about it resembles a company failing.

The half worth weighing is what is missing. That page says nothing at all about cancelling, notice periods, early termination charges or any right to leave. Ofcom's rules give you a way out only if the terms change. A provider has to give a month's notice of a contract change that is not purely administrative, and a month to leave without an early termination charge; a transfer that keeps your price and your term triggers neither. So a customer whose contract is sold keeps the deal they chose and loses the ability to change their mind about who they bought it from, and that is the ordinary operation of the rules rather than anything either company did wrong.

Our guide to leaving a contract early explains what an exit charge may and may not include, and switching broadband covers One Touch Switch from both ends.

Where the scoreboards agree, for once

Direct answer: This is the one section of a head-to-head where the scoreboards usually disagree, and on this pairing they do not. TalkTalk is the most complained-about broadband provider in Ofcom's table and has been for three quarters running. Ofcom logged 10 complaints per 100,000 for TalkTalk against 7 for BT, where the average is 6; the Which? panel scored BT 65% against 59%; Trustpilot has BT at 3.9 out of 5 against 2.2 out of 5.

On most of these pages we spend this section explaining why two measures disagree, because a complaints rate and a satisfaction panel are counting different things and usually point different ways. Here they do not. Every public measure we can find puts BT ahead, and the one that counts actual escalations to the regulator puts TalkTalk last of everybody, not merely behind BT: the highest of any broadband provider, above the industry average of 6 and above Vodafone (8), BT (7), Virgin Media and EE (6), Sky (5) and Plusnet (4), and the only broadband figure Ofcom does not declare statistically comparable to any other provider

Two caveats, in both directions. Trustpilot is the weakest of the four, because people who write a review unprompted are rarely the ones who had a quiet year. And a complaints rate is a rate of escalation rather than a measure of how most customers feel: 10 per 100,000 is ten customers in a hundred thousand, so the overwhelming majority of TalkTalk's customers never complained to anybody. What the figure does tell you is that when a TalkTalk relationship breaks down it is more likely than any competitor's to end up at the regulator, and it has been that way for three quarters.

Our complaints and your rights guide covers the process end to end, and The Complaints Floor looks at what happens to customers of providers too small for Ofcom to table at all.

The social tariff, where there is no comparison

Direct answer: TalkTalk is the only one of the large providers absent from Ofcom's list of social tariffs. Ofcom's list carried 33 tariffs when we read it on 20 September 2026, and TalkTalk is on none of them. On a qualifying benefit this is not a comparison. BT Home Essentials starts at £16.50 and is open to new customers; TalkTalk has nothing at any price.

This is the largest single gap on the page and it is the one least likely to appear in a comparison, because it applies to a minority of households and to them it is worth more than everything else here put together. BT Home Essentials starts at £16.50 a month. BT Home Essentials is open to anyone on the qualifying benefits, whether or not they are already a BT customer. Eligibility is the usual list: Universal Credit, Pension Credit, income-based Employment and Support Allowance, income-based Jobseeker's Allowance and Income Support.

TalkTalk's position is not a cheaper tariff or a harder one to qualify for. It is no tariff. We checked its own site and we checked Ofcom's list, which was last updated 17 August 2026 and runs from 4th Utility to YouFibre taking in every provider of any size, and TalkTalk is absent from it. For a household on a qualifying benefit, the cheapest thing TalkTalk sells is its ordinary entry package, which is more than twice the price of BT's social tariff.

It is worth being clear that this is not an accusation of anything. There is no obligation on any provider to run a social tariff, several do not, and TalkTalk's ordinary prices are among the lower ones in the market, which is its own form of help. But if you are on one of those benefits, this section is the whole comparison and the rest of the page is detail.

Our guide to social tariffs lists every provider that runs one, what it costs and who can apply.

What else comes with each

Direct answer: TalkTalk wins on set-up, charging £0 where BT charges an activation fee, and includes network level filtering on every plan. BT answers with a Wi-Fi guarantee that pays out, security software included, and a published ceiling on the price after the term. TalkTalk publishes no Wi-Fi guarantee at all: no promised speed in a room, no remedy and no credit.

Two rows in that table are worth more than they look. The Wi-Fi row is a real difference rather than a marketing one, because one of these companies has written down a speed it will deliver in a room and a hundred pounds it will pay if it cannot, and the other has written down nothing. Wi-Fi is the part of a broadband service most likely to disappoint, and it is the part a household has least ability to fix itself.

The early termination row cuts the other way from what you might expect of a budget provider. BT's charge falls as the term runs down, because it is the bill you would have paid. TalkTalk's is a flat rate for every month left, and on the entry tier that rate sits close to the monthly price itself, so leaving early costs a TalkTalk customer roughly what staying would have.

Our guide to exit fees and setup fees compares the cost at both ends of a contract across the market.

The safety nets, and the asterisk on one of them

Direct answer: Both have signed Ofcom's speed code and both are in the automatic compensation scheme, which several cheaper providers have not and are not. But TalkTalk is in the scheme too, but Ofcom's own list carries a caveat beside its name that no other member has: restrictions apply for customers not on the Openreach network. BT sells over Openreach only, so nothing equivalent applies to it.

Start with the good news, because on this measure both of these providers are at the strong end of the market. Both have signed Ofcom's voluntary code of practice on broadband speeds, so both owe you a guaranteed minimum figure at the point of sale and a right to leave if it is not met. Both are in Ofcom's automatic compensation scheme, so a missed appointment, a delayed repair or a delayed start pays out without you asking. The rates are the scheme pays £10.34 a day for a delayed repair, £32.31 for a missed appointment and £6.46 a day for a delayed start. Several of the cheaper networks a postcode check will show you have signed neither code, and for a lot of households that safety net is worth more than a few pounds a month.

Now the asterisk, because it is the sort of detail that only matters on the day it matters. TalkTalk is in the scheme too, but Ofcom's own list carries a caveat beside its name that no other member has: restrictions apply for customers not on the Openreach network. TalkTalk sells the same tiers over Openreach and over CityFibre at the same price, and publishes no way to tell which you would get short of checking a postcode. So a TalkTalk customer cannot tell from the price, the tariff name or the speed whether the automatic compensation scheme will cover them in full, and the only way to find out is to check the address and then ask.

On speed the two promises are the same shape and one of them is easier to hold a company to. BT publishes a guaranteed minimum speed on every plan and calls the promise its Stay Fast Guarantee: if speeds are not back to normal within thirty days it will let you leave without an early cancellation fee. TalkTalk's speed promise is the same shape as BT's: if the speed stays below the guaranteed minimum and TalkTalk cannot fix it, you may leave without penalty. The difference is the figure: BT prints its guaranteed minimum on the card you buy from, so you know on day one what the promise is measured against, while TalkTalk discloses yours in the order confirmation. TalkTalk's own two pages do not agree on how long it gets to fix it: the help centre says thirty working days and the terms of use say thirty days.

Our speed test records what you are actually getting with a timestamp, which is what a speed complaint needs, and whether poor speeds let you leave early covers the remedy.

Who should choose which

Direct answer: TalkTalk at the entry tier and nowhere else, on this pairing. BT everywhere above it, because above the entry tier TalkTalk is not meaningfully cheaper and every other column goes BT's way. Neither, if the postcode check turns up something cheaper on the same line, which it often does.

That table is one sided in a way the others on this site are not, and it is worth saying why rather than leaving it to look like a preference. On most pairings the two providers are trading different strengths: one is cheaper and one is better, or one gives you certainty and the other gives you an exit. Here the cheaper one stops being cheaper at the tier most households buy, and once that is gone there is no column left where TalkTalk leads except the set-up fee and the entry price. Compare the tier you actually want rather than the cheapest one either company advertises. On this pairing the answer changes completely between the two.

The third option this page would otherwise hide

Direct answer: On an Openreach line the choice is never only these two: the same cable carries a dozen other retailers, and the cheapest of them is usually cheaper than both. On our own table of 340 deals from 29 providers, read on 1 October 2026, entry prices ran between £23 and £34 a month with a median of £28, and the cheapest was £13.50 a month for the first 12 months, then £18.00 (4th Utility, 150 Mbps on CityFibre).

A head-to-head page has a built-in bias and it is worth naming rather than pretending otherwise. By setting two brands against each other it quietly asserts that those two are the choice, and on an Openreach line they are not. The same fibre into the same house is sold by BT, Sky, EE, Plusnet, TalkTalk, Vodafone, NOW, Zen and a dozen more, over 23.4 million premises as at 30 June 2026. Several of them undercut both providers on this page, and on this pairing that matters more than usual, because the cheaper of the two is not cheap at the tier most people want.

That does not make BT and TalkTalk bad choices. Both have signed Ofcom's speed code and both are in the automatic compensation scheme, which several cheaper providers have not and are not. For a lot of households that safety net is worth the difference. But it should be a decision you make rather than one the page makes for you, which is why the comparison below is not filtered to these two alone.
