Why bother?
When a fixed contract ends, many providers move you to a higher out-of-contract price. Ofcom requires broadband and phone providers to tell you before your contract ends and show you their best deals, and Ofgem rules let you switch energy without exit fees in the last 49 days of a fixed deal. Bill Fighter helps you use that moment.
Want a nudge? Create a free account to save your contract end dates and we'll email you about 40 days and 10 days before each one ends.

Honest bits
- We don't search for deals yet. You bring a better price you've found on a comparison site or provider website.
- Reading a photo isn't perfect, so we always ask you to check the details.
- Your provider decides whether to lower your price. A letter makes it easier to ask, but it's not guaranteed.
