Compare an energy cost scenario

Use your annual electricity and gas consumption to see a regional price-cap reference. Check your energy region and tariff before using the result to plan spending.

Rates apply from 1 October to 31 December 2026. The annual and monthly figures below make usage scenarios easier to compare. They are not a forecast for the next year, a supplier quote or a limit on your total bill. Rates can change after this period.

These figures cover default tariffs in England, Scotland and Wales. Northern Ireland, fixed tariffs and multi-rate electricity such as Economy 7 are not supported. Water, broadband and other utilities are separate costs.

Your energy region

Energy regions differ from council and city boundaries. Check your region with Ofgem.

How you pay

Standard credit means paying when you receive a bill. Prepayment means buying meter credit in advance.

Connected supplies to include

A connected supply can have a standing charge even when usage is zero. Leave out a fuel only if you do not have that supply.

Annual electricity use, kWh

Use your annual bill or your own assumption. Leave blank only for a gas-only scenario.

Annual gas use, kWh

Enter kWh from your bill, not cubic metres. Leave blank only for an electricity-only scenario.

I have checked the energy region, payment method and default-tariff scope. Any included electricity uses a single-rate meter.

Check the source and your own bill

The reviewed source is Ofgem Annex 9 v1.11. Its regional charges are published before VAT. For this period, the source states 0% VAT for electricity and 5% for gas. Direct Debit corresponds to the workbook's “Other Payment Method” category. Multi-rate electricity requires separate peak and off-peak assumptions and is left out.

Look at your supplier's actual tariff and the official price-cap explanation before relying on a spending estimate. The price cap does not mean that every home pays the headline annual figure.
