Common questions

Do any of these need my registration number?

No. The plate decoder reads the mark in your browser without sending it anywhere. Other calculations use only the dates, rates, distances or vehicle details that you enter.

Where do the figures come from?

GOV.UK, HMRC, DVLA, DVSA, the Sentencing Council, legislation.gov.uk, EUR-Lex, DESNZ and Ofgem, each named on the page that uses it with the date it was read. Where nothing is published, the page says so rather than estimating.

How often are the rates updated?

Vehicle excise duty changes on 1 April, company car percentages on 6 April, fuel prices weekly and the energy price cap quarterly. Each page shows the date on which its sources were checked.
