FAQ
When is a heat pump tariff worthwhile?
If you want a separate tariff for heat pump electricity, you should know how much your own heat pump uses. If it consumes more than 5,000 kilowatt hours a year, a heat pump tariff is worth it. Below that a conventional electricity tariff usually works out better. Our tariff calculator helps you find that out quickly.

Does the tariff work with every heat pump?
Yes, whether air-to-water, ground source or water-to-water: our heat pump tariff suits all common types. The only requirement is a separate meter for the heat pump electricity, which most new installations already have.
