It usually arrives quietly. An email with a subject line about “changes to your account”, or a direct debit that leaves your bank a few pounds heavier than last month. Your broadband still works exactly as it did yesterday, but you are suddenly paying more for it. If you want to know why your bill went up, whether the rise was allowed, and whether it gives you a way out of your contract, this page works through it in the order most people ask the questions. And if the rise has you wondering whether you are on the right package at all, run a quick check on the SpeedTestUK homepage to see the speeds you actually get for the money.
The short version is this: for most people, the rise was written into the contract on the day they signed up, and broadband price rises are not a billing error. But there are three different situations that all feel identical when the email lands, and which one you are in decides what you can do about it.
Situation one: you signed after 17 January 2025
If you took out your contract on or after 17 January 2025, your price rise almost certainly follows the new rules. From that date, Ofcom banned providers from writing inflation-linked or percentage-based rises into new broadband, mobile and pay TV contracts. The old formula, typically inflation (CPI) plus 3.9%, meant nobody could know at sign-up what they would be paying a year later. Ofcom’s research found most customers did not understand it, so it was scrapped.
Under the current rules, any rise has to be set out in pounds and pence, prominently, before you sign, along with the date it takes effect. A typical contract now reads something like: £27 a month until April, then £31 a month. That is clearer, but it has not made the rises smaller. Ofcom’s February 2026 pricing report found that in-contract rises announced for 2026 ranged from £2 to £4 a month for fixed broadband. MoneySavingExpert’s tracking of current contracts shows Virgin Media, BT, Plusnet, TalkTalk and EE applying £4 a month each April, and Vodafone £3.50. There is no cap on the amount, which is why consumer groups continue to campaign on the issue.
The uncomfortable consequence: because the rise was clearly stated before you agreed to it, it does not give you a right to leave penalty-free. You accepted the full price path of the contract, not just the headline month-one price. The lesson is for next time, not this time. When comparing deals, compare the total cost across the whole minimum term, rises included, rather than the teaser monthly price.
Situation two: you are on an older, inflation-linked contract
Contracts signed before 17 January 2025 were not rewritten by the new rules. If yours says the price rises each year by CPI plus 3.9%, that clause can keep applying until the contract ends. Many customers on those legacy terms paid 7.3% more in spring 2026, because the rise used the January inflation figure plus the provider’s fixed percentage on top.
Even here, the rise itself is part of your contract, so it does not normally open a penalty-free exit. What does open one is a rise that goes beyond what the contract allows. If your bill has gone up by more than the stated formula, or at a different time of year than your terms describe, that is a different matter: challenge it, because providers do make billing errors, and a rise applied outside the contract terms is one you do not have to accept.
There is one provider-shaped exception worth knowing. Sky and NOW do not write annual rises into their contract terms in the way the others do. When Sky announced broadband and home phone rises from 1 April 2026, affected customers were told they had 30 days from being notified to cancel penalty-free, even mid-contract. If your provider’s model is “we may raise prices, and when we do you may leave”, that notification email is a genuine window. Miss the 30 days and it closes.
Situation three: your contract has simply ended
The biggest jump on any broadband bill is usually not a mid-contract rise at all. It is the end-of-contract jump, when an introductory price expires and the rolling monthly price steps up, sometimes by £10 or £20 a month. That is not a price rise in the contractual sense, and it needs no notice period beyond the end-of-contract notifications providers must send you.
The good news is that out of contract, you hold all the cards. You can switch away or re-contract with the same provider whenever you like, at no penalty. Our guide to UK broadband providers explains which networks and brands compete for your custom, and if you want a benchmark for what BT, the provider whose pricing people ask us about most, currently charges, see how much is BT broadband. Households that drift for years on an expired deal are the ones funding everyone else’s introductory discounts.
When a price rise does let you leave for free
There is a clear rule underneath all of this, in Ofcom’s General Conditions. If a provider raises your price by more than your contract set out, or introduces a rise the contract never mentioned, that counts as a change to your detriment. The provider must give you at least one month’s notice in a form you can keep (a letter, email or text), tell you that you may leave, and let you end the contract within a month of that notice without any early termination charge. You pay only your normal bill up to the day you leave.
So the practical test is a comparison exercise. Find your original order confirmation or contract summary. Find the rise that was stated there. Compare it with the rise on your bill. If they match, the rise was agreed and the exit door stays shut. If they do not match, or no rise was stated at all, contact the provider, quote the mismatch, and say you are exercising your right to leave without penalty. Do it in writing if you can, and do it within the notice window, because the right expires.
One grey area: rises to extras outside your core subscription, such as a TV add-on or a call plan, follow the provider’s terms for those products rather than a single simple rule. If a bundled element has gone up sharply, it is still worth a call. Providers would often rather adjust a bill than lose the whole account.
What £4 a month really costs: a worked example
To make the arithmetic concrete, here is an illustrative example, using round numbers rather than any real customer’s bill. Imagine a package at £26 a month with a £4 rise each April, on a 24-month contract. The rise adds £48 over the following year. If a second £4 rise lands in month 13 of the contract, the monthly price ends at £34, and the total paid across the 24 months is roughly £90 more than the same contract with no rises at all. That is why a deal that looks £2 cheaper than a rival in month one can be the more expensive deal by month eighteen. Always add up the full term.
This is also why the flat pounds-and-pence model hits cheaper packages harder in percentage terms. A £4 rise on a £20 social-style tariff would be 20%; on a £50 premium package it is 8%. The rules made rises predictable, not proportionate.
Five things to do when the rise email arrives
- Do not delete it. If the rise turns out to be one you can reject, the notification date starts your one-month clock. You will need the email.
- Check which situation you are in. Contract start date, the rise clause in your contract summary, and whether your minimum term has ended. Five minutes with your paperwork answers all three.
- Do the full-term sum. Work out what you will pay between now and the end of your contract at the new price, and compare it with switching once any exit fee is included. Sometimes paying a fee to leave still wins; often it does not.
- Call before you cancel. Even where you have no formal right to leave, retentions teams can often freeze a rise or move you to a better tariff. That is a separate conversation, covered by our haggling guide, but the rise notification is the strongest prompt to have it.
- Diary the next decision point. If you are stuck until your contract ends, set a reminder two weeks before the end date. End-of-contract is when you are most valuable to every provider, including your current one.

Frequently asked questions
Can my provider legally raise my broadband price mid contract?
Yes, if the rise was set out in your contract. Since 17 January 2025, rises in new contracts must be stated in pounds and pence before you sign. A rise that was never in your contract, or that is bigger than the one stated, is a different matter: you must be given at least a month’s notice and the right to leave without a penalty.
Why did my bill go up by 7.3% when my neighbour’s went up by £4?
You are almost certainly on different generations of contract. Yours, signed before January 2025, still uses the old inflation-plus formula (CPI plus 3.9% produced 7.3% in spring 2026). Your neighbour’s newer contract has a flat pounds-and-pence rise instead. When either of you re-contracts, you will both move onto the flat model.
Do price rises apply to social tariffs?
No. Social tariffs for people on qualifying benefits are sold on the basis that the price stays fixed during the contract and there is no early exit fee. If you are eligible and your standard bill keeps climbing, a social tariff is usually the single biggest saving available, and our social tariffs article explains who qualifies.
Will refusing the rise and leaving hurt my credit file?
Leaving properly, under a contractual right or at the end of your term, does not. Walking away mid-dispute without cancelling properly can, because unpaid bills may be marked as defaults. If you believe you have a penalty-free exit, get the provider to confirm the cancellation and the zero exit fee in writing before you stop paying.
How can I avoid mid contract rises on my next deal?
Some providers and smaller networks still sell genuinely fixed-price contracts, and social tariffs are always fixed. Where a rise is written in, choose the deal with the lowest total cost over the full term rather than the lowest starting price, and treat the stated rise dates as part of the deal you are judging.
Know your number before you negotiate
A price rise email feels like an instruction, but it is really an invitation to check your position. Which generation of contract are you on, what rise was actually agreed, and how long is left? With those three answers, the right move is usually obvious. Before you ring anyone or start shopping, run our broadband speed test and note your real speeds. If you end up switching or re-contracting, you will know whether the new deal genuinely beats the service you have today, rather than just the price of it.
