UK mid-contract price rises in 2026: your Ofcom rights explained

News · 12 Jun 2026 · Daniel Reid

If you are bracing for mid-contract price rises on your UK phone or broadband bill, the single question that decides what you can do is which track your contract sits on, and whether that lets you walk away without a penalty. Ofcom banned inflation-linked mid-contract rises in any deal sold from 17 January 2025, ruling that providers must instead state any increase upfront in pounds and pence, so your rights now depend almost entirely on the date you signed (Ofcom, July 2024 statement; BBC, January 2025).

What mid-contract price rises mean after the Ofcom ban

For years, UK telecoms bills carried a clause almost nobody read at sign-up: an annual increase pegged to inflation, usually the Consumer Prices Index or the Retail Prices Index, plus a flat 3.9 percentage points on top. When inflation spiked, those rises landed at double digits, and customers had no way to predict the total cost of a two-year deal. Ofcom decided that was unfair. In its 2024 ruling, the regulator said it was unfair to expect customers to accommodate surprise price rises linked to inflation, which it noted “can be incredibly volatile and… difficult to predict” (BBC reporting on Ofcom, January 2025).

The fix was not to cap rises but to make them visible. From 17 January 2025, any new phone, broadband or pay-TV contract that includes a mid-contract increase must spell out that increase as a specific pounds-and-pence amount, with the timing stated, before you sign. You might still face a rise every April, but you can now see exactly what it will be over the life of the deal. That is the central change, and it is why two customers on the same network can face very different increases in 2026 depending only on when they last signed or recontracted.

The practical upshot is that the old “wait and see what inflation does” anxiety is gone for newer contracts, replaced by a fixed number you can budget around. But the legacy clauses did not vanish overnight. Providers were allowed to keep applying inflation-linked terms to contracts that were already running, which is why the UK now operates a two-track system that will take years to fully unwind. Working out which track you are on is the first and most important step, and it is simpler than it sounds.

Which track am I on? A clean decision flow

Start with one date: when did you last sign or recontract? If your current deal began before 17 January 2025 and you have not changed it since, you are almost certainly on the legacy track. That means your contract can still raise prices by CPI or RPI plus 3.9%, which in 2026 works out at roughly 7.7% on many tariffs. On a £40 broadband bill, that is close to £3 a month, and on a larger bundle it can be more. The exact figure depends on which inflation measure your provider uses and the rate published in the qualifying month, so check your provider’s price-rise page for the confirmed percentage rather than guessing.

If you signed, upgraded or recontracted on or after 17 January 2025, you are on the new fixed-pound track. Your rise is a flat monthly amount that was disclosed when you signed, and it cannot be inflation-linked. This is the track most people will move onto naturally as old contracts expire, and it is the one that makes budgeting predictable. If you are unsure, your contract paperwork or online account will show the start date, and any rise notice you have received should state whether it is a percentage or a fixed pound figure. A percentage means legacy; a fixed pound figure means the new rules. Our guide to picking the best EE plan in the UK for 2026 covers how recontracting resets you onto the newer terms.

One nuance worth flagging: bundling can blur the picture. If you take broadband and mobile from the same provider, or sit inside a discount scheme like Vodafone Together or O2 Volt, each element may have its own contract date and its own rise. It is entirely possible to be on the legacy track for one service and the new track for another within the same household. When in doubt, treat each line on your bill as a separate contract and check its start date individually.

The 2026 fixed-pound rises by provider

For customers on the new track, the April 2026 increases have landed as fixed monthly amounts. On broadband, BT, EE, Plusnet, Virgin Media and TalkTalk newer contracts sit at around £4 a month, with some earlier post-ban deals at £3. Sky has applied a flat £3 a month to broadband customers in 2026, with £1 to £3 on some TV packages. Vodafone applies £3.50 a month for contracts taken from 12 November 2025, and £3 for some earlier fixed-rate deals. TalkTalk’s £4 figure applies to contracts from 16 November 2025. These figures come from Uswitch and CompareFibre’s 2026 guides, which track the published notices, but you should spot-check them against your own provider’s notice because the exact amount can vary by contract date and package (Uswitch, April 2026; CompareFibre, June 2026).

On mobile, the increases are smaller but follow the same logic. O2 applies £2.50 across contracts, Vodafone £2.50 for newer contracts from November 2025, and EE around £2.50. Sky Mobile is the cheapest of the major players at £1.50 for most plans, while Three sits between £1.80 and £2.50 depending on the plan and whether you are SIM-only or on a handset deal. If you are weighing your options across networks, our comparison of EE versus Vodafone for 2026 and our Vodafone versus O2 breakdown set out where the better value sits once these rises are baked in.

Two customers on the same network can face very different increases in 2026 depending only on when they last signed.

A word of caution on these numbers: they are 2026 notices compiled by comparison sites, and providers occasionally adjust amounts or apply different figures to specific legacy bands. Treat the figures above as a strong starting point, then confirm the precise amount on the letter, email or in-app notice your provider sent you. That notice is the legally binding statement of what you will pay, and it is also the document that starts your clock for leaving.

When you can leave penalty-free

This is where the date of your contract matters most. Under the new fixed-pound model, the rise was disclosed when you signed, so it is treated as a known term of the contract rather than a surprise change. That means a fixed-pound increase does not, by itself, automatically trigger a right to leave penalty-free in the way a surprise variation used to. The trade-off Ofcom struck was transparency at sale in exchange for certainty during the contract.

Legacy contracts work differently, and the picture is more generous in places. Where a provider makes a change that materially disadvantages you and was not clearly fixed at sale, you generally have a right to exit without an early termination charge, and providers must give written notice of rises. In practice, many affected customers get around 30 days from notification to cancel penalty-free. Sky states this explicitly for its broadband customers, telling them they can cancel within 30 days of being notified of a rise. Other providers apply their own notice and exit terms, and some Sky TV packages and legacy deals limit the right, so read the specific notice you received (Sky; general Ofcom-aligned guidance).

If you are out of your minimum term entirely, none of this restricts you: you can switch whenever you like, and the One Touch Switch process for broadband now makes moving between most providers a single request to your new supplier. The bigger savings usually come not from disputing a £3 rise but from leaving a long-expired contract that has rolled onto a higher out-of-contract price. If that is you, the rise notice is a useful prompt to act. Our look at the best UK full-fibre broadband deals and our EE versus Three guide after the VodafoneThree merger are good places to benchmark what a fresh deal should cost.

For mobile customers, the same principle holds. A small fixed rise on a newer contract is unlikely to open an exit window, but if you are out of contract you are free to move, and an eSIM transfer between most UK networks now takes minutes rather than days. If you are on a legacy mobile deal facing a 7.7% jump, check whether your notice gives you a cancellation window before deciding whether to ride it out or switch. Our Virgin Media O2 2026 mobile guide walks through how Volt bundling and contract dates interact for O2 customers.

One route that sidesteps the whole question is to avoid fixed-term contracts that carry annual rises in the first place. SIM-only rolling deals, pay-as-you-go and 30-day broadband contracts typically do not impose the same April increases, because you are never locked in long enough for them to apply. They can cost a little more per month than a long tie-in, but they hand you the freedom to leave the moment a price moves, which is its own form of insurance against future rises.

Our verdict

Our position is that the Ofcom reform was a genuine improvement, and most UK customers should now treat the annual rise as a budgeting fact rather than a reason to panic. If you are on the new fixed-pound track, a £2.50 to £4 monthly increase is rarely worth the disruption of switching on its own, especially mid-contract where you have no penalty-free exit. The smarter move is to diarise your contract end date and shop hard then, when you have leverage and a clean exit. If you are still on a legacy inflation-linked contract facing a near 7.7% rise in 2026, that is a different calculation: check your notice for a cancellation window, and if you have one, use the threat of leaving to negotiate or move to a fixed-pound deal that ends the uncertainty for good. Either way, the date you signed is the answer to almost every question, so find it first.
