Meter Sums

About Meter Sums

Clear home-energy maths for England and Wales, so you can see whether a battery, solar panels, a heat pump or a new tariff makes sense for a home like yours.

Who makes this

Made by a small independent creator based in Norway. Narration in the videos uses a synthetic voice. Images of the model house are AI-generated. All households shown are models unless stated otherwise. The narrator is not a person with a house, an installation or an engineering background, and never claims to be.

What we do

  • Show the sums behind a home-energy decision, step by step.
  • Say what a number depends on, and the number at which the answer flips.
  • Say which numbers are facts, which are examples and which are unknown.

What we do not do

  • No affiliate links. No payments from installers, retailers, suppliers or manufacturers.
  • No product reviews and no ranked lists of products or brands.
  • No financial, tax or electrical advice. This is general information.
  • No cookies or tracking from this site, no sign-up, no newsletter. A video loads from YouTube only if you press play.

Where we cover

England and Wales. Scotland and Northern Ireland have different rules, schemes and suppliers, so we do not cover them yet.
