TLDR: **Yes — if you don't want your bill to go up.**

You're on 24.6p/kWh. If you do nothing by **28 Nov 2026**, you'll be auto-moved on 1 Jan 2027 to their Standard Variable tariff at **34.1p/kWh** [~39% more expensive] — ignore the "nothing else you need to do" line.

To avoid it:
1. Log into your Fennick online account / app **before 28 Nov 2026**
2. Choose a new tariff — they suggest Fixed Saver 27 if you want to stay fixed. Check the price there before you pick.

They've also updated Terms & Conditions from 1 Jan 2027 but that's not urgent.

Want help checking if Fixed Saver 27 is actually a good deal?
