Broadband Contracts Explained: What to Check Before You Sign (2026)

Before signing a broadband contract, check: the monthly price and any setup fees; contract length (typically 18 or 24 months); the annual mid-contract price increase amount (now stated in £); early termination fees if you leave early; and the out-of-contract price after your deal ends. Since January 2025, Ofcom requires all price rises to be stated as fixed £ amounts.

Types of Broadband Contract

UK broadband contracts come in four main lengths. 24-month deals offer the lowest monthly price — BT, Sky and Virgin Media all favour this length, with superfast packages starting around £25–£28/month. 18-month deals typically cost £1–£3/month more than 24-month equivalents but give you earlier access to new-customer pricing. 12-month deals suit renters or those wanting to switch sooner, though they are less widely available. Rolling monthly (30-day) contracts charge the most per month but let you leave with just 30 days' notice. Compare options on our best broadband deals page.

What to Check Before Signing a Contract

Every provider must give you a Key Facts document before you sign — read it. Check the monthly price including any introductory discount, the guaranteed minimum speed (you can exit if the provider consistently fails to deliver it), and any setup fee. Pay close attention to the mid-contract price rise clause. Since January 2025, Ofcom banned CPI+X percentage increases — rises must now be a fixed £ amount stated upfront. For April 2026, BT and EE will add £4/month, Plusnet £4/month, Virgin Media £4/month and Sky £3/month. Also note the early termination fee — typically calculated as remaining monthly payments multiplied by a discount factor.

Your Rights: Cooling Off and Cancellation

Ofcom guarantees a 14-day cooling-off period on every new broadband contract. The clock starts from the day you sign or the day your service activates — whichever is later. During this window, you can cancel for any reason with no early termination charge. After the cooling-off period, leaving mid-contract means paying an exit fee, which most providers calculate as the outstanding monthly payments minus a small discount. Once your minimum term ends, you can cancel or switch at any time with 30 days' notice and zero penalties. You can also cancel your broadband penalty-free if your provider raises prices above the amount stated in your contract, or if they cannot deliver the guaranteed minimum speed.

What Happens at the End of Your Contract?

When your minimum term expires, your broadband automatically rolls onto an out-of-contract tariff — often £5–£15/month more than your deal price. Ofcom requires providers to send an end-of-contract notification at least 10 days before your deal ends, reminding you of the new price and your best available tariff. This is your cue to act. You have three options: renegotiate with your current provider (call retentions and ask for a new-customer equivalent deal), switch provider via One Touch Switch (over 1.6 million UK customers have used it since April 2023), or simply do nothing and stay on the rolling rate. Providers like Vodafone automatically move you to their best equivalent tariff at end-of-contract, but most others do not.

Frequently Asked Questions

What is a typical broadband contract length in the UK?

Most broadband contracts are 18 or 24 months. Some providers offer 12-month or even 1-month rolling contracts, though these tend to cost more per month. Student-specific deals may offer 9-month contracts.

What happens when my broadband contract ends?

When your minimum term ends, you automatically move to a rolling out-of-contract tariff, which is almost always more expensive. Your provider must notify you when your contract is ending. This is the best time to negotiate a new deal or switch providers.

How much is an early termination fee?

Early termination fees vary by provider but are typically calculated as the remaining monthly payments on your contract. Some providers discount this amount. BT, for example, charges the remaining monthly fees minus any discount. Always check before signing.

Can I cancel my broadband within 14 days?

Yes. Under Ofcom rules, all broadband customers have a 14-day cooling-off period from either signing the contract or the service being activated (whichever is later). During this period, you can cancel without any early termination charge.
