United Kingdom Energy Cost Calculators
Estimate household energy bills, gas heating costs, heat pump running costs, and EV charging costs in the UK.
United Kingdom households can face very different energy costs depending on climate, dwelling type, electricity and gas tariffs, fixed charges, and whether electricity is used for heating, cooling, hot water, or transport. The country pages are designed to help you begin with a transparent estimate, then replace the defaults with figures from your own bill.
Choose the calculator that matches the decision in front of you. An energy-bill estimate is useful for checking a current tariff, while solar, heat-pump, and EV tools are better for comparing scenarios. Keep the billing period, unit rate, daily charge, and equipment assumptions visible so a future result can be checked or updated.
Do not treat a national or regional starting value as a confirmed local tariff, rebate, or quote. Utilities, installers, and public authorities publish the terms that apply to a household. If an assumption looks wrong, use the feedback form to explain the issue and include a public source where possible.
Use the result to frame questions rather than to replace the documents that govern your service or purchase. Check the currency, billing period, tariff type, and local units before comparing alternatives, and revisit the estimate when a household change or published rate update affects the inputs.
