**TLDR: Yes — do something before 28 November 2026, or your rate jumps ~39%.**

- Your current tariff (Fixed Saver 24, 24.6p/kWh) ends 31 Dec 2026.
- If you do nothing by **28 Nov 2026**, you'll auto-move to their Standard Variable tariff at **34.1p/kWh** (plus 61.2p/day standing charge) — significantly more expensive.
- To stay on a fixed rate, log into your account/app and select **Fixed Saver 27** before that date.

The T&C changes need no action from you.

One tip: before switching to Fixed Saver 27, it's worth a quick comparison of other suppliers' deals — you're free to switch away entirely rather than just accepting their default offer.
