**TLDR:** Yes, you need to act if you want to avoid a price increase.

- **Your current plan** (Fixed Saver 24) ends on **Dec 31, 2026**.
- **If you do nothing** by **Nov 28, 2026**, you'll be auto-switched to their Standard Variable tariff, which is **much more expensive** (34.1p/kWh vs your current 24.6p/kWh).
- **Action required:** Log into your account before **Nov 28, 2026** and select **Fixed Saver 27** to keep a fixed rate.
- The Terms & Conditions changes (meter readings, complaints, emails) are just informational – no action needed.

**Bottom line:** Log in and pick Fixed Saver 27 before the end of November, or your bill will jump significantly in January.
