Energy bill checker

Check the arithmetic on a simple household electricity bill. Add the figures printed on your bill to see what its import charge, standing charge and VAT should come to.

Supports up to three import rates and one standing charge. Leave out export credits, debt repayments, discounts and payments already made.

Use the import unit rate shown on the bill, before VAT.

Use the daily figure shown on the bill, before VAT.

How this is calculated

Electricity used is multiplied by the unit rate, then the daily standing charge is added for every day in the billing period. If selected, the standard 5% domestic VAT is added to that subtotal. This is a check of the arithmetic, not a judgement on whether a tariff is right for you.
