About Energy Calculators
Free calculators that show what home energy costs in Great Britain, using official prices and showing every step of the sum.
Who we are
Energy Calculators is published by Youell Systems Ltd and edited by Max Youell. It went live on 13 November 2026.
We build calculators that answer one question each, properly. Every price comes from a published source such as Ofgem or GOV.UK, and every result has a "Show the workings" button so you can check the sum yourself.
What we are not
We are not an energy supplier, a comparison site or a financial adviser. Our calculators give information, not advice, and they estimate from what you enter. We do not sell your details and there is nothing to sign up to.
