Energy Calculators

Whether you are comparing energy tariffs, estimating solar panel savings, or working out the running cost of household appliances, our energy calculators give you instant results based on current UK energy prices and Ofgem cap rates. Energy costs are one of the biggest household expenses in the UK, and the landscape keeps shifting with quarterly Ofgem price cap adjustments and new incentives for renewable technologies. Our calculators help you understand what you spend today and model the savings from efficiency upgrades, solar panels, heat pumps, and battery storage. From basic wattage conversions to detailed solar ROI projections, each tool is designed for UK homeowners and uses current tariff rates, standing charges, and generation estimates based on UK sunlight data. Understanding your energy consumption is the first step toward cutting your bills and reducing your carbon footprint.
