**Yes — do this one thing:** Log into your online account or app and pick **Fixed Saver 27** before **28 November 2026**. **Why it matters:** Your current tariff (24.6p/kWh) is being withdrawn. If you do nothing, you'll be moved to their Standard Variable tariff at **34.1p/kWh** — nearly 10p more per unit, which could add hundreds per year depending on usage. The letter's line "there is nothing else you need to do" is misleading; you still need to actively choose a new fixed tariff to avoid the price jump. **Everything else:** Terms & Conditions updates — nothing for you to do there.
