Heat Pump Plus is a tariff add-on that charges just 15p per kWh for the electricity your heat pump uses at any time of day. This offers ends on 1 February 2026.
What is a heat pump tariff?
If your home has a heat pump choosing a heat pump tariff can make a big difference to your bills.
A heat pump energy tariff is designed for households with air source or ground source systems, offering lower rates at particular times of day. That means you can power your heat pump for less by shifting usage to cheaper off-peak periods.
In order to use a heat pump tariff you will need a smart meter capable of half-hourly readings.
Which suppliers offer heat pump tariffs?

Thinking about getting a heat pump?
If you haven’t installed a heat pump yet, it could be the right time to start exploring your options. A heat pump can provide reliable, low-carbon heating and, when paired with the right tariff, it can also help keep your energy bills down.
Government support
You may be able to get up to £7,500 towards the cost of installing a heat pump through the Boiler Upgrade Scheme (England & Wales).
Frequently asked questions
Do I need a special tariff for a heat pump?
No. A few suppliers market tariffs for heat pumps, but many standard time-of-use or smart tariffs also work well to reduce costs if you can use more electricity during off-peak hours.
Do I need a smart meter for a heat pump tariff?
Yes. Almost all heat pump electricity tariffs require a smart meter that can record half-hourly data. This ensures your supplier bills you correctly for usage.
Are heat pumps expensive to run?
Not if you’re on the right tariff. Heat pumps are much more efficient than boilers, and with a time-of-use tariff they can be cheaper to run than gas heating.
Can I combine a heat pump tariff with solar panels?
Yes. Pairing solar with a heat pump tariff can cut costs further. You can use solar to power the heat pump during the day and a cheap overnight tariff to heat water or charge a battery.
What’s the best tariff for a heat pump?
It depends on your usage. If you’re flexible, a time-of-use tariff (like the ones mentioned above) is usually the cheapest. If your usage is steady, a flat-rate tariff may suit you better. Always compare to find the best fit for your home.
