**Yes—act before 28 November 2026 or your bill jumps ~38%.** Your cheap tariff (24.6p/kWh) ends 31 Dec 2026. If you do nothing, you'll auto-move to their Standard Variable tariff at **34.1p/kWh** + **61.2p/day** standing charge. **Do this:** Log into your online account/app and switch to **"Fixed Saver 27"** before **28 Nov 2026** to lock in a fixed price and avoid the hike. *(The T&C updates need no action, but the tariff switch definitely does.)*
