If you're weighing a heat pump against a traditional gas boiler, this calculator offers a clear breakdown of your expected annual running costs. It uses your local energy prices and system efficiencies to pinpoint exactly how well a heat pump needs to perform to save you money. Keep in mind that this focuses strictly on day-to-day energy bills, so you'll want to budget separately for the upfront installation costs and any potential government rebates.
