HomeBillGuide helps homeowners and renters in the United States and Europe understand what home energy really costs, and how to pay less for it.

We publish data-backed cost guides, running-cost comparisons, and practical checklists covering heat pumps, boilers, insulation, solar panels, smart thermostats, and the everyday upgrades that decide how much a home costs to run. Prices are shown in US dollars, British pounds, and euros wherever the data allows, and every cost figure is backed by a dated source, such as government statistics, energy agencies, and published installer and retailer price ranges.

When prices or grants change, we update our guides instead of leaving old numbers online. HomeBillGuide is an independent publication and is not affiliated with any energy company, installer, or manufacturer.

Some of our articles contain affiliate links. If you buy through one of those links, we may earn a small commission at no extra cost to you. This never changes our prices, comparisons, or recommendations.
