**TL;DR: Yes — don't ignore it, or your bill goes way up.**

Your current tariff **Fixed Saver 24 (24.6p/kWh) ends 31 Dec 2026.**

If you don't pick a new one **before 28 Nov 2026**, you'll be automatically moved to their expensive **Standard Variable tariff: 34.1p/kWh + 61.2p/day** standing charge.

**What to do:**
Log into the app/online account and switch to **Fixed Saver 27** before 28 Nov to stay on a fixed price. Check its rate first — it's not in the email.

The "there is nothing else you need to do" line just means nothing *bad* will happen contract-wise — you'll just pay a lot more.
