24-month broadband deals: the commitment case (honestly told)
A 24-month broadband contract delivers the lowest monthly price on the UK market: typically £10 to £20 less per month than rolling, and £3 to £5 less than 12-month equivalents. Over the full two-year term that is £240 to £480 saved versus rolling, plus the best hardware bundles and promotional offers. The trade is real: two years of lock-in, two rounds of in-contract price rises, and a meaningful early-termination fee if life changes. This page makes both cases honestly, so settled households can commit with confidence and less-settled households can pick something that fits better.
The six things to know first
Maximum monthly saving
24-month contracts deliver the lowest monthly price of any UK broadband contract length: £10 to £20 less than rolling, £3 to £5 less than 12-month. Over the term that is £240 to £480 saved.
Best hardware bundles and promotions
Providers reserve their top promotional offers for 24-month customers: upgraded routers, mesh Wi-Fi systems, TV subscriptions, streaming credits, and cashback of £50 to £200.
ETF equals remaining monthly payments
Leave at month 12 of a £25 contract and you pay roughly £300 in early-termination fees. This is why 24-month only makes sense when you genuinely expect to see out the full term.
Two price rises, not one
A 24-month term typically covers two April uplifts under UK provider pricing structures. Under Ofcom rules, both must be stated in pounds and pence before you sign. Stack both into your total-cost calculation.
Fibre overbuild locks you out
If FTTP arrives at your address during year two of a 24-month FTTC contract, you cannot switch to it without paying the ETF. In areas with active fibre rollout, this risk is real and worth factoring in.
Best fit: settled homeowners, stable lives
The sweet spot is owner-occupiers in areas where fibre has already arrived (no better tech coming), with stable jobs and no move plans. Narrower profile than most comparison pages admit.

Enter your postcode →What a 24-month contract actually offers
A 24-month broadband contract commits you to 24 minimum monthly payments. In exchange, the provider gives you the lowest headline monthly price in their range, usually bundles in better hardware (upgraded router, mesh Wi-Fi kit, sometimes TV packages or streaming subscriptions), and often adds cashback or promotional incentives worth £50 to £200. It is the option providers push hardest because it stabilises their revenue for two years.
Early-termination fees apply if you leave before month 24, and they are substantial: typically equal to the remaining monthly payments, minus any promotional discount. Leave at month 12 of a £25/month deal and the ETF is roughly £300. Leave at month 18 and it is roughly £150. This is why 24-month contracts are only worth picking when your commitment to the address, provider and household situation is genuinely secure.
The savings case: why the monthly price is lowest
UK broadband providers can afford to discount 24-month contracts because a two-year customer is more profitable than a one-year customer at the same price. Customer acquisition costs (sales, marketing, activation, equipment) get amortised over more months, and the provider does not need to re-sell to you partway through. That efficiency is passed back as a lower monthly rate.
Typical UK figures: 24-month fibre deals run £20 to £32 per month; 12-month equivalents run £22 to £35; rolling deals run £28 to £45. Over a full 24-month term, these monthly differences add up to real money:
- vs rolling: £10 to £20 per month saved × 24 months = £240 to £480 total saving
- vs 12-month: £3 to £5 per month saved × 24 months = £72 to £120 total saving
- Plus hardware bundles: £50 to £150 of effective value if you would have bought the router, mesh, or included TV separately
- Plus cashback offers: £50 to £200 on many deals, if you jump through the reward-claim process correctly
Add these together and a 24-month deal can deliver £400 to £800 more value than a rolling alternative over the term. That is the upside. The next section is the downside.
The risk case: what two years of lock-in really means
Two years is a long time in UK broadband. Four specific risks are worth thinking through before committing.
You move home mid-contract
Even settled households can face unexpected moves: jobs, families, relationships, health. Leaving mid-contract means ETFs. Some providers waive them if they cannot serve the new address; always confirm this clause at sign-up.
Fibre overbuild arrives in year 2
UK FTTP rollout is ongoing. If new fibre reaches your street 14 months into a 24-month FTTC contract, you cannot switch to it without paying the ETF. In areas with active rollout, this risk is non-trivial.
Two price rises compound
A £25/month deal with a £3 April uplift in year 1 rises to £28, then (on a typical provider structure) a further uplift in year 2 stacks on that base. Over 24 months, stacked uplifts can add £100 or more to the effective total cost.
Market prices fall, you miss out
UK broadband prices have trended down as altnet competition grows. A 24-month lock-in means you miss those falls for the second year. A 12-month contract catches them at the renewal point.
Three-way total-cost comparison
Representative UK figures: rolling at £35/month, 12-month at £25/month, 24-month at £22/month. All assume £0 setup and no early-termination fees. The highlighted row at 24 months of stay shows where 24-month becomes the clear winner.
| Length of stay | Rolling (£35/mo) | 12-month (£25/mo) | 24-month (£22/mo) | Best choice |
|---|---|---|---|---|
| 6 months | £210 | £150 + ~£100 ETF | £132 + ~£400 ETF | Rolling |
| 12 months | £420 | £300 | £264 + ~£264 ETF | 12-month (saves £120 vs rolling) |
| 18 months | £630 | £450 (incl. 6 post-term) | £396 + ~£132 ETF | 12-month (saves £180 vs rolling) |
| 24 months | £840 | £600 | £528 | 24-month (saves £312 vs rolling) |
| 36 months | £1,260 | £900 (or renew once) | £792 + renew | 24-month + renew |
The highlighted row captures the key insight: at exactly 24 months of stay, 24-month saves £312 versus rolling and £72 versus 12-month. Add the typical hardware bundle value and cashback (£100 to £350 combined), and the total 24-month advantage can exceed £400 to £700 over the term, if you see it through.
Example assumes no in-contract price rises. Under Ofcom's 2025 rules, any scheduled uplifts must be stated in pounds and pence before sign-up. For 24-month deals, factor in both annual uplifts using the pounds-and-pence figures in your contract.
Decision matrix: when 24-month is right
24-month contracts fit a specific, narrower profile. The honest version of this page steers readers who do not match the profile toward 12-month or rolling instead.
The commitment makes sense
Maximum savings pay off when
- You own your home and have no realistic move plans for the next two years
- Full fibre has already reached your address; there is no better technology coming
- Your household and job situation have been stable for 2+ years already
- The 24-month monthly price is £5 or more per month below the 12-month alternative
- The deal includes genuinely useful hardware (mesh Wi-Fi, upgraded router) or cashback you will claim
- You can cope with two annual price rises and have factored both into your budget
- You value set-and-forget simplicity over year-by-year optimisation
Shorter contracts fit better
When 24-month is the wrong commitment
- You rent and your tenancy is less than 24 months remaining: pick 12-month
- Fibre rollout is active in your area and FTTP might arrive within 12 months: pick 12-month
- You expect any chance of moving within 2 years: pick 12-month or rolling
- The 24-month price is less than £3 per month cheaper than 12-month (not worth the lock-in)
- You have lived at your address less than 12 months and the situation is still settling: pick 12-month
- You qualify for a social tariff: compare that first
- You are a student or in a short let: pick rolling

What to check before signing a 24-month deal
Five checks that separate a solid 24-month contract from one where the apparent discount quietly dissolves over two years.
Five-step 24-month check
Run through each before you commit to two years.
Compare monthly price against the 12-month alternative
The comparison tool shows both. Ideally the 24-month price is £5 or more per month below the 12-month version. That is £120+ saved over 24 months, which justifies the lock-in. A gap of less than £3/month often does not.
Read BOTH annual price rise amounts
Under Ofcom rules (Ofcom, 2024a), any scheduled uplifts must be stated in pounds and pence before sign-up. For 24-month deals, check both the year-1 and year-2 figures. Stack them: £3 in April year 1, then £3 in April year 2 on top of that, means year 2 costs £72 more than the headline rate.
Confirm the house-move waiver clause
If you move to an address the provider cannot serve, many UK providers waive the ETF. But some do not. Ask directly and confirm in writing. For a 24-month contract, this clause is worth a £200 to £500 insurance premium if you have any move possibility in year two.
Verify the cashback claim process
Many 24-month deals include £50 to £200 cashback, but the claim process can be strict: specific window (often months 3 to 6), specific form, specific way to access your account. Miss the window and the cashback is lost. Set a diary reminder at sign-up, not after.
Check fibre rollout status at your postcode
If you are picking a 24-month FTTC deal, check whether any altnet or Openreach FTTP rollout is planned or underway at your address. A reliable data point is Ofcom's coverage checker. If fibre is coming within 12 months, 12-month is usually the wiser choice.
Two annual price rises: the maths
This deserves its own section because it is where 24-month headline maths most often goes wrong for real customers.
Under Ofcom rules effective from January 2025 (Ofcom, 2024a), any in-contract price rise must be disclosed in pounds and pence at sign-up, not linked to inflation. Typical UK deals now specify a fixed £3 per month uplift each April.
A 24-month contract starting in November 2026 will pass through two April uplifts: April 2027 and April 2028. A £22/month deal with £3 annual uplifts looks like this:
| Period | Months | Monthly rate | Period cost |
|---|---|---|---|
| Nov 2026 - Mar 2027 | 5 | £22 | £110 |
| Apr 2027 - Mar 2028 | 12 | £25 | £300 |
| Apr 2028 - Oct 2028 | 7 | £28 | £196 |
| Total over 24 months | 24 | n/a | £606 |
| Naive (no uplifts) total | 24 | £22 | £528 |
The real total is £606, not £528: a 15% uplift on the naive calculation. Factor both April uplifts into your side-by-side comparison with 12-month and rolling alternatives. Full background in our in-contract price rises guide.

24-month broadband: frequently asked questions
How much cheaper are 24-month deals than 12-month?
Typically £3 to £5 per month cheaper on the same speed and package from the same provider. Over 24 months that is £72 to £120 saved, plus potentially better hardware bundles and cashback. If the 24-month price is less than £3 per month below the 12-month equivalent, the saving is usually not worth the two-year lock-in: pick 12-month instead.
What happens if I move home during a 24-month contract?
Three options. First, most UK providers will transfer the contract to your new address if they can serve it there, usually without an ETF and sometimes with a small house-move fee. Second, if the new address is outside the provider's network, many waive the ETF entirely. Always confirm this clause at sign-up. Third, if neither applies, you pay the ETF (remaining monthly payments minus any discount). See moving home broadband for the detail.
Can I get full fibre (FTTP) on a 24-month contract?
Yes, this is where 24-month deals are strongest. Most UK FTTP providers include major brands (BT, Sky, Virgin Media, Vodafone) and altnets (Hyperoptic, Community Fibre, YouFibre, Gigaclear, Zen, etc.). They offer 24-month FTTP options. Premium tiers like gigabit symmetrical are often exclusively available on 24-month terms. See the FTTP deals page for availability.
How do the two annual price rises work on a 24-month contract?
Under Ofcom rules effective from January 2025 (Ofcom, 2024a), any scheduled uplifts must be stated in pounds and pence before you sign, not linked to inflation indices. A typical 24-month contract passes through two April uplifts of £3 each; the second stacks on the already-raised base. Check your contract for both year-1 and year-2 exact figures and factor both into your total cost. Our in-contract price rises guide covers the detail.
What hardware bundles typically come with 24-month deals?
This varies by provider, but 24-month customers typically get the provider's best router (Wi-Fi 6 or 6E mesh systems on some plans), optional TV add-ons at a discount (Sky Stream, BT TV, Virgin TV), included streaming credits (Netflix, Disney+, NOW), and cashback offers of £50 to £200. The effective value of these bundles over 24 months can be £150 to £400+ if you would have bought them separately anyway.
Can I upgrade speed or package mid-contract?
Usually yes, with most UK providers. Upgrading (increasing your monthly cost) is typically free and resets or extends the minimum term to a new 24 months. Downgrading (decreasing your cost) is usually not allowed until the minimum term ends. Adding services (TV, phone) mid-contract is straightforward; removing them may require negotiation.
What happens after the 24 months end?
Unless you take action, most UK 24-month contracts automatically roll onto a higher "out of contract" rate that can be £15 to £25 per month more than the promotional price. Providers must notify you as the minimum term approaches. Your three sensible moves at month 24: renew with the same provider at a new promotional rate (often possible via their retention team); switch to a better deal using One Touch Switch (Ofcom, 2024b); or move to a rolling 1-month while you work out your longer-term plan. Set a calendar reminder for month 23 to compare actively.
Is a 24-month contract ever worse than a 12-month one?
Yes, in three specific cases. First, if the monthly price gap between 24-month and 12-month is under £3 per month at your postcode. The saving does not justify the extra year of lock-in. Second, if UK altnet fibre rollout is actively planned for your area within the next 12 months. Being locked out of a potentially better deal in year two can cost more than the 24-month saving. Third, if your life circumstances are stable but not permanently fixed (not yet a homeowner, job could change, family planning). The 12-month option preserves optionality for a small premium.
