Compare current tariff against a new quote

Switching checklist

Do this before you press switch

Use annual kWh

Monthly Direct Debit can be too high, too low or seasonal. Annual usage is the clean comparison input.

Check exit fees

Fixed tariffs may have exit fees if you leave early, but Citizens Advice says you can usually switch fee-free in the final 49 days.

Take a meter reading

Record readings on switch day and keep screenshots of quoted rates, dates and credits.
