Mid-contract price rises: can you leave your broadband deal free?

Last updated: 29 October 2026

Every spring the same letter lands: “We’re writing to let you know your price is changing.” And every spring millions of people assume that because they’re mid-contract, there’s nothing to be done. Often that’s wrong. Whether you can walk away without paying a penny depends on one thing: was this exact rise, in pounds and pence, written into your contract before you signed? If it wasn’t, Ofcom’s rules give you 30 days to leave free — and that’s worth more than most people realise.

Information, not advice. We don’t recommend products or providers. Check the official source linked below before you act.

The rule in one line

A price rise you were clearly told about before signing is part of the deal; a price rise you weren’t is a change to the deal — and you don’t have to accept changes that make you worse off.

Ofcom’s General Conditions (C1.14 to C1.17) say a provider that changes your contract in a way that isn’t to your benefit must give you at least one month’s notice, tell you about your right to leave, and let you terminate within one month of that notice without paying any early termination charges. Only three kinds of change are exempt: ones purely to your benefit (a free speed upgrade), purely administrative ones (a new address for complaints), and ones forced by law (a VAT change).

The complication is that most contracts do include a price rise. Whether yours gives you an exit comes down to how it was written — and when you signed.

What changed on 17 January 2025 — the pounds and pence rule

For years, telecoms contracts tied their annual rise to inflation: “CPI + 3.9% every April” was the standard wording. Nobody signing in October could know what that would be worth the following spring, and when inflation spiked it produced double-digit rises that were technically “in the contract”.

Ofcom’s answer, announced on 19 July 2024 and in force from 17 January 2025, was to ban inflation-linked and percentage-based price-rise terms in all new phone, broadband and pay-TV contracts. From that date, any rise written into a new contract has to be set out in pounds and pence, prominently and transparently, at the point of sale, along with when it will happen. That’s why your contract summary now says something like “your price will rise by £3 on 1 April each year” rather than quoting a formula.

Two things follow:

• Signed on or after 17 January 2025? Your contract can only contain a fixed £/p rise. If the letter you’ve received asks for more than that figure — or your contract summary doesn’t mention a rise at all — you have a free exit.
• Signed before 17 January 2025? The old inflation-linked clause can still be applied for the rest of your minimum term, as long as it was made clear when you signed. The ban wasn’t retrospective.

The single most useful check: open your contract summary (your provider had to give you one before you signed, and it’s usually in your online account) and find the price-rise line. Compare it with the letter. Same amount or less — no free exit. Bigger, or not there at all — you can leave.

When you can leave penalty-free

Put plainly, you get the 30-day penalty-free exit if any of these is true:

1. No rise was mentioned in your contract summary, and now you’ve been told of one.
2. A rise was mentioned, but this one is bigger. A £3 rise in the contract and a £4 rise in the letter is a change you didn’t agree to, even if the difference is small.
3. Your contract started on or after 17 January 2025 and the rise is a percentage or inflation-linked. That term shouldn’t be there at all under Ofcom’s rules. Providers have largely moved to fixed amounts, so this is rare — but if you see it, you can push back.

And you don’t get the free exit if:

• The rise is exactly the £/p amount your contract summary stated, applied on the date it said. That’s the deal you signed.
• You signed before 17 January 2025 on a clearly explained inflation-linked clause, and the provider has applied that formula correctly.
• You’re out of your minimum term — in which case you never needed a special right; you can leave with 30 days’ notice anyway, and you should probably be haggling or switching regardless.

What the big names have written into current contracts

Since the rule change, the main providers publish their fixed annual rise. These are the figures on their own pages as of 29 October 2026 — check yours, because the amount depends on exactly when you signed:

• TalkTalk applies a flat £4 a month rise each April to broadband contracts taken out on or after 16 November 2025. Customers who joined between 12 August 2024 and 15 November 2025 have a £3 rise; anyone still in a contract from before 12 August 2024 is on the old CPI + 3.7% formula. TalkTalk’s own example: a £28 deal signed after 16 November 2025 becomes £32 from April 2026 and £36 from April 2027.
• Vodafone home broadband contracts on the price plan effective 26 August 2026 rise by £3.50 a month on 1 April each year (Essentials social-tariff broadband excluded).
• O2 pay-monthly voice plans rise by £2.50 a month each April; data-only and smartwatch plans by 75p. O2’s page currently describes the change arriving from April 2027 for new contracts, with out-of-bundle charges rising 5% from 1 April each year.
• Sky told customers prices “may change from 1 April 2026” and sent the details by letter and email rather than publishing a single figure. If you’re with Sky, the letter is your source.

None of those rises, applied exactly as written, triggers a free exit. They’re examples of the deal you agreed to. What triggers it is a mismatch.

A worked example: when the letter doesn’t match the contract

Priya signed an 18-month broadband deal on 3 March 2025 at £29 a month. Her contract summary says: “Your monthly price will increase by £3 on 1 April each year.” On 18 February 2026 she gets an email: her price is rising by £3 from 1 April. The rise matches the contract. No free exit — she has 7 months left, so leaving would cost her up to £203 (7 × £29) in early termination fees, against a rise costing her £21 over the rest of the term. She stays, or haggles.

Her neighbour Tom signed a 24-month deal on 20 January 2025 at £32 a month, and his contract summary makes no mention of any rise. On 18 February 2026 he gets the same email: £3 a month from 1 April. That rise isn’t in his contract. He has until 20 March 2026 (30 days from the notice) to leave with no fee at all, escaping the £35 a month he’d otherwise be paying for the remaining eleven months — or, better, to use that right as leverage.

Use the free exit as leverage first

A penalty-free exit is valuable even if you have no intention of leaving. The retentions team knows that a customer who can walk is a customer worth keeping, and they have discretion that the first person who answers the phone doesn’t.

Say you’d like to cancel. That routes you to retentions. Then use the script the checker gives you — the core of it is:

“I’ve received notice that my price is going up by £3 a month. That rise wasn’t set out in pounds and pence in my contract, so under Ofcom’s rules this is a change I’m entitled to exit from without an early termination charge. My 30-day window runs until 20 March. Before I do, is there a price you can offer that keeps me? Otherwise please process my cancellation and confirm in writing there’ll be no exit fee.”

Three things make this work: you’ve quoted the rule, you’ve named the deadline, and you’ve given them an easy way to say yes. Have two or three real new-customer prices for your speed ready to quote back — our guide to haggling your broadband bill walks through the whole call, and if it’s your mobile that’s going up, our SIM-only comparison will tell you what the same data costs elsewhere.

If they won’t budge, leave. Broadband switching is now a single request to the new provider under One Touch Switch, and your old provider can’t charge an early termination fee once you’ve exercised the right in time.

Found you can leave? Compare first

Before you ring retentions, know what you’d be moving to. A concrete alternative is what turns “I might leave” into a price cut — and if they call your bluff, you want to be able to switch the same day.

Compare broadband deals at MoneySuperMarket for your postcode, then come back and make the call. Whatever you find, write down the provider, speed and monthly price so you can quote it.

If you can’t leave free: what the exit fee really is

If the rise was in your contract, your choices are to accept it, haggle, or pay to leave. The early termination fee is at most the monthly price multiplied by the months left on your minimum term — that’s the “up to” figure the checker shows. In practice providers are expected to reduce it for the costs they save when you go (no more wholesale line rental, for instance), so the real number is often lower. Ask for the exact figure in writing before you decide; sometimes a new deal elsewhere is cheap enough that paying to leave still comes out ahead over a year.

If your provider says no

Providers do sometimes refuse a valid exit, or try to route you to a fee. Don’t argue with the first agent indefinitely:

1. Make a formal complaint in writing. Quote Ofcom General Conditions C1.14–C1.17, give the notice date, and state that the rise wasn’t set out in pounds and pence in your contract summary. Ask them to confirm a fee-free cancellation.
2. Keep the deadline. Tell them clearly, within the 30 days, that you’re exercising your right to terminate. A written notice sent inside the window protects you even if the dispute drags on.
3. Escalate for free. If the complaint isn’t resolved after eight weeks, or you get a deadlock letter sooner, take it to your provider’s alternative dispute resolution scheme — every provider must belong to either CISAS or the Communications Ombudsman. Ofcom’s site has a checker to tell you which.
4. Tell Ofcom. Ofcom doesn’t handle individual complaints, but it monitors them, and patterns trigger investigations.

For the broader complaints playbook, see how to complain and get compensation. And if the rise has you questioning the whole bill, how to cut your broadband bill covers social tariffs too — if you receive certain benefits, they can be far cheaper than anything retentions will offer.

Frequently asked questions

Can I leave my broadband contract early because of a price rise?

Yes, if the rise wasn’t set out in your contract, or is bigger than the amount that was. Ofcom’s rules treat that as a contract change that doesn’t benefit you: your provider must give at least a month’s notice and let you leave within 30 days without an early termination charge. If the rise was clearly stated in pounds and pence before you signed, and the provider sticks to that amount, there’s no free exit.

What is the pounds and pence rule?

From 17 January 2025, Ofcom banned inflation-linked and percentage-based price-rise terms in new phone, broadband and pay-TV contracts. Any rise written into a contract from that date must be stated in pounds and pence, prominently, at the point of sale, with the dates it applies.

I signed before January 2025 and my rise is CPI plus 3.9%. Can I leave?

Usually not, as long as the inflation-linked clause was made clear when you signed and the provider applies exactly that formula. The ban only covers contracts taken out from 17 January 2025. You can still haggle, or pay the early termination fee and switch if a new deal saves you more over the year.

How long do I have to cancel after a price rise notice?

30 days from the date you were notified. Ofcom’s General Conditions require providers to let you terminate within one month after notification and to tell you that deadline in the notice. Tell the provider you’re leaving before the window closes, and keep a record of when you did.

How much is the early termination fee if I can’t leave free?

At most, roughly your monthly price multiplied by the months left on your minimum term. Providers usually reduce this for the costs they save when you leave, so ask for the exact figure in writing before you decide.

What if my provider refuses to let me leave without a fee?

Make a formal complaint quoting Ofcom’s rules on contract changes. If it isn’t resolved after eight weeks, or you get a deadlock letter sooner, take it free to the provider’s alternative dispute resolution scheme — CISAS or the Communications Ombudsman.
