**TL;DR: Yes — probably.**

Your current fixed tariff ends **31 Dec 2026**. If you do nothing by **28 Nov 2026**, you’ll be moved to their **Standard Variable tariff**, which looks more expensive: **34.1p/kWh** vs your current **24.6p/kWh**.

**What to do:**
- Before **28 Nov 2026**, log in via the official app/website and choose a tariff — they suggest **Fixed Saver 27**.
- Check the Fixed Saver 27 rate first; it may be better or worse than other deals.
- If you don’t care and do nothing, you’ll likely pay more.
