How do I compare energy tariffs in the UK?
Where a link is marked *, it is a partner link — we receive commission at no extra cost to you. Links without a * earn us nothing. How we make money.
In short: Use annual kWh from your bill, compare unit rates and standing charges, add exit fees and check whether a fix beats the Ofgem cap over the contract term.

The price cap limits default tariff unit rates — not your total bill.
Model full contract cost including disclosed mid-contract rises on new contracts.
Use an Ofgem-accredited comparison service for whole-of-market quotes.
