How to cancel British Gas

What its contract says about leaving.

We read the British Gas terms on 12 April 2026. The company may have changed them since, and your contract may be different.

What the contract says about leaving

Early exit fees on fixed tariffsIf you leave a fixed-rate tariff before the end date, you may have to pay an exit fee (typically £25-£50 per fuel). This means you could be locked in even if cheaper deals appear.
Auto-rollover to expensive variable tariffWhen a fixed deal ends, you are automatically moved to the standard variable tariff, which is usually more expensive. You need to actively choose a new deal.

This page does not explain how British Gas handles cancelling (by phone, on its website or with a form). For that, see the company's own page.

This is not legal advice. It is a summary, made with the help of AI, of the terms the company publishes.
