How to switch your energy supplier in seven simple steps

A practical, compliant guide to switching energy suppliers, covering what to check and what to expect during switching.

Switching your energy supplier is straightforward and regulated by Ofgem. There are no guaranteed savings—your outcome depends on your current tariff, usage, and the deals available when you compare. This tool gives you a readiness checklist, a short snapshot of what to expect from comparing, and a seven-step timeline so you know the process and your rights, including the 14-day cooling-off period and continuous supply.

Frequently asked questions

How long does switching take?
Switching usually takes around 21 days from when you agree to switch until the change is complete. Your supply is continuous—only the company billing you and the tariff change. Ofgem rules require suppliers to coordinate the switch.
Will I lose my meter readings or smart meter data?
No. Your meter stays in place. If you have a smart meter, it will continue to record usage; the new supplier may need to enrol it (especially older SMETS1 meters). Your final reading is used to close your old account. Historical data is not lost.
Are there exit fees when switching?
If you are on a fixed-term tariff, your contract may include an exit or early termination fee for leaving before the end date. During the renewal window (often the last 49 days of your contract), you can usually switch without a fee. Check your contract or contact your supplier to confirm.
