**TLDR: Yes — you should do something, despite the "nothing else you need to do" line (that only refers to the T&C tweaks).**

Your cheap fixed deal (24.6p/kWh) ends 31 Dec 2026. If you do nothing by **28 Nov 2026**, you're auto-moved to the Standard Variable tariff at **34.1p/kWh** — about 39% more per unit, plus a 61.2p/day standing charge. That's the expensive default.

**What to do:**
1. Before 28 Nov 2026, log into your account/app.
2. Check the actual rate of "Fixed Saver 27" — they don't state it here, so don't assume it's good.
3. Compare it against other suppliers (price comparison site / Ofgem's list). You're free to switch anytime, but check if your current fixed deal has an exit fee — usually there isn't one near the end of a fixed term.
4. Pick one and confirm in writing/app. If you want no hassle and are fine paying more, doing nothing gets you SVT.

The T&C changes (meter readings, complaints, email contact) need no action from you.

Not sure what's cheapest for your usage? Paste in Fixed Saver 27's rates and your rough annual kWh and I can ballpark it.
