Compare energy tariffs and switch supplier

Work out your real energy use, compare fixed and variable tariffs fairly, and switch gas and electricity supplier without gaps in supply or surprise fees.

Estimated time: 30–45 minutesUpdated: 2 October 2026

Use this guide when your fixed deal is ending, you are on a standard variable tariff and want to check the alternatives, or you have moved home. Have a recent energy bill or your supplier app, and your current meter readings.

Step by step

  1. Find your annual usage in kWh

    Look on your latest bill or annual statement for your estimated annual consumption in kWh for gas and electricity separately. This number, not your monthly direct debit, is what you need for a fair comparison. If you have just moved or your bill uses estimates, take actual meter readings and give them to your current supplier first. Note your tariff name, whether you pay by direct debit, and any exit fee and end date shown on your bill.
