Price rises should be shown in pounds and pence
Since 17 January 2025, new telecoms contracts cannot use inflation-linked or percentage-based price rise terms. Any in-contract increase must be shown upfront, clearly, in pounds and pence.
Estimate how a broadband price rise affects your monthly bill, yearly cost and remaining contract spend before deciding whether to switch, complain or renegotiate.
UK broadband bill calculator
Use this calculator to estimate the monthly increase, yearly impact and remaining-contract cost of a broadband price rise. It works for newer fixed pounds-and-pence increases and older percentage-style contract wording.
Use the result as a quick affordability check before accepting a renewal, challenging a notice or comparing a new broadband deal.
Calculator
Enter your current monthly broadband price, choose the price-rise type and add the contract months you want to model. For new contracts, providers should show in-contract price rises upfront in pounds and pence.
Price rise rules
Ofcom’s rules changed how new broadband, phone and pay-TV contracts can describe future in-contract price rises. The calculator is designed to handle both newer fixed-price terms and older percentage-style wording.

Since 17 January 2025, new telecoms contracts cannot use inflation-linked or percentage-based price rise terms. Any in-contract increase must be shown upfront, clearly, in pounds and pence.
Contracts agreed before 17 January 2025 may still contain older annual price-rise terms. Use percentage mode if the provider notice refers to an inflation-linked adjustment.
Technical benchmark: legacy terms commonly referenced a published CPI or RPI inflation figure plus a fixed provider margin, often 3.9 percentage points. Check the exact contract wording and the specific inflation month named by the provider rather than assuming every older contract used the same benchmark.
A small monthly rise can still matter over 12, 18 or 24 months. Compare the post-rise monthly bill with available deals and any exit fee.
Before you switch
Use these checks before accepting a renewal, challenging the bill or moving provider. A cheaper deal is useful only if the service and contract terms also work for your home.

| Contract End Date | Out-of-contract users can usually switch or negotiate without early termination charges. | Out-of-Contract Saving Guide |
| Exit Fees | Early Termination Charges can wipe out the saving from a cheaper alternative network. | Can I Switch Early? |
| Price-Rise Wording | For agreements signed from 17 January 2025, check whether the exact pounds-and-pence increase was stated clearly before you agreed to the contract. | Broadband Switching Rights Audit Hub |
| Available Networks | Openreach FTTP, Virgin Media cable or full fibre, and independent altnets can vary by street and building. | Fibre Broadband Availability Checker |
| Social Tariff Eligibility | Eligible households may be able to move to a lower-cost social tariff rather than accept a standard renewal price. | Broadband Social Tariffs Comparison |
Compare the new monthly price with current offers. You may have stronger leverage to negotiate or move.
Check the notice against the contract wording and calculate whether any exit fee outweighs switching savings. If the rise was not clearly set out in your contract, or is higher than the contract allowed, you may have a 30-day window to leave without exit fees after the provider notice.
Keep screenshots, order emails and renewal messages. Ask the provider to explain where the increase was shown.
Run wired tests and keep evidence. Poor performance may create a different complaint route from price alone. If your service dropped entirely or a repair was delayed, check the Broadband Compensation Calculator.
Check social tariffs, payment support and cheaper packages before missing payments.
Check whether broadband, TV, landline or mobile services sit under one linked agreement or separate contracts. If a provider changes a bundled service beyond the price-rise terms you agreed, you may have a right to leave the affected contract without penalty after the required notice. Whether that right extends across the whole bundle depends on how the services are contracted and billed.
Subtract the old monthly price from the new monthly price, then multiply the difference by 12. The calculator also shows the cost over the number of months you choose.
For new contracts from 17 January 2025, providers cannot use inflation-linked or percentage-based price rise terms. They must show any in-contract increase upfront in pounds and pence.
Yes. Older contracts agreed before 17 January 2025 may still include percentage-based or inflation-linked wording. Check your original contract and the provider notice.
It depends on your contract, whether you are in the minimum term, the wording of the price rise and whether the provider followed the required notice process. Check exit fees before ordering a new deal.
No. Cancelling payments can create billing and credit problems. Complain, switch correctly or negotiate with the provider instead.
