**Yes, you probably need to act.**

- **Your current tariff (Fixed Saver 24) ends on 31 Dec 2026.**
- **If you do nothing by 28 Nov 2026**, you'll be moved to their Standard Variable tariff: **34.1p/kWh vs your current 24.6p**. That's about **39% more per unit**, and the price can change at any time.
- **To avoid that**, log into your account or app and pick a new tariff (they suggest Fixed Saver 27) **before 28 Nov**.

**Things to check before you switch:**
- The letter doesn't say what **Fixed Saver 27** costs. Look up its unit rate, standing charge, and any exit fees.
- It also doesn't give your current standing charge, so compare that too.
- You don't have to stay with Fennick. It's worth checking a comparison site in case another supplier is cheaper.

**The T&Cs update** (meter readings, complaints, email contact) is just FYI. No action needed unless you want to read the details.

Despite the "nothing else you need to do" at the end, the one thing that matters is **choosing a new tariff by 28 Nov 2026**.
