Broadband Exit Fee Calculator
Broadband contracts typically run for 18 or 24 months, and leaving early almost always means paying an early termination charge — but that charge is not always the end of the conversation. Depending on how much a better deal would save each month, and whether your provider has raised prices since you signed up, paying to leave early can still work out cheaper overall, or may not be needed at all. This calculator works out which situation you are actually in.
Broadband Contract Exit Fee Calculator
Calculate your exact early termination charge and work out whether switching now still saves you money despite the exit fee. Uses Ofcom's fair usage rules.
The Price-Rise Loophole Most People Don’t Know About
Since January 2022, Ofcom rules give broadband customers the right to leave a contract without any exit fee if their provider raises prices mid-contract by more than the rate set out in the contract terms — typically CPI inflation plus an additional percentage. Several major providers raised prices by 7-9% in recent annual price rises, comfortably clearing that threshold for many customers. If this applies to you, the exit fee that would otherwise apply is waived entirely, and only 30 days’ notice is required — checking whether your provider has recently raised prices is worth doing before assuming a fee is unavoidable.
The right applies specifically to mid-contract price rises — increases that happen partway through a fixed term you already agreed to, rather than the price you are quoted for a brand new contract. Providers are required to give advance notice of these increases, usually with several weeks’ warning, which is also the window in which the right to exit without penalty needs to be exercised.
How Providers Actually Calculate the Fee
Most major providers calculate an early termination charge the same way: your current monthly bill multiplied by the number of months left on the contract. Ofcom rules cap the fee at this remaining-charges figure, meaning a provider cannot charge more than what you would have paid by simply staying until the contract ended — in principle, leaving early should never cost more than staying put would have, even before accounting for any saving from a better deal elsewhere.
A small number of providers apply a modest discount to this figure rather than charging the full remaining amount, on the basis that they save some cost by not having to service the account for the rest of the term. This varies by provider and is not something to assume applies by default — the remaining-months calculation is the standard baseline most customers should expect.
The Break-Even Question
The real decision comes down to how quickly a cheaper deal recovers the cost of leaving. Dividing the total switching cost — the exit fee plus any new setup fee — by the monthly saving gives a payback period in months. A short payback period, recovered within a few months, makes switching straightforwardly worthwhile even before the new contract ends. A longer payback period is not necessarily a reason to stay, though — it depends on comparing the total saving over the full length of the new contract against the upfront cost, since a modest monthly saving sustained over 18 or 24 months can still comfortably outweigh a larger one-off fee.
A Quick Comparison
Someone paying £42 a month with 8 months left on their contract faces a gross exit fee of around £336. If a new deal costs £28 a month — a £14 monthly saving — that fee is recovered in 24 months, longer than the 8 months remaining on the old contract, making it worth simply waiting out the current term rather than paying to leave early.
Change the numbers slightly — the same £336 fee but a £30 monthly saving instead of £14 — and the fee is recovered in around 11 months, comfortably within a typical 18-month new contract, tipping the decision toward switching now rather than waiting.
Reading the Recommendation
This calculator gives one of several outcomes depending on your numbers: an immediate switch if you are already out of contract or qualify for the price-rise exemption, a clear “worth it” recommendation if the fee is recovered within a few months, a borderline call if payback sits in the middle range and might be worth negotiating with your current provider instead, or a “wait until your contract ends” recommendation if the exit fee outweighs what a new deal would realistically save you before it does. None of these are absolute rules — they are a structured way of comparing the numbers rather than a single right answer for everyone.
Once you know whether switching makes sense, our Broadband Finder can help identify deals to compare against your current bill, and our Broadband Savings Calculator looks at the saving over a full contract term in more detail if you want to go beyond a simple payback calculation.
Frequently Asked Questions
How do I know if my provider raised prices recently?
Check your bill history or account notifications for an annual price change notice, usually sent every March or April. Your provider is required to notify you in advance of any increase, so this should appear in your email or online account.
Can I negotiate my exit fee down?
Exit fees themselves are generally fixed by contract terms and are not usually negotiable directly, though some providers will offer a retention deal — a lower ongoing price to persuade you to stay — if you call to say you are considering leaving.
Does the exit fee include line rental or just broadband?
This depends on your specific package — bundled deals covering broadband, line rental, TV and mobile can each have separate remaining commitments, so it is worth checking your contract summary for how the total fee is broken down.
What if I am moving house?
Most providers offer a home-move service that can transfer your existing contract to a new address without triggering an exit fee, provided broadband is available there. This is usually a separate process from cancelling outright.
Is there a cooling-off period for a new contract?
Yes — UK consumer law generally gives a 14-day cooling-off period for new contracts signed online or over the phone, during which you can cancel without penalty, separate from any exit fee on the contract you are leaving.
Does switching affect my credit score?
Signing up for a new broadband contract typically involves a credit check, which can leave a soft or hard search on your file depending on the provider, but this is generally minor and separate from any impact of the exit fee itself.
What happens if I do not pay the exit fee?
An unpaid exit fee is treated as an outstanding debt and can be passed to a debt collection agency or affect your credit file, so it is worth resolving directly with your provider rather than simply stopping payment.
