## 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.
