We’re proud to offer great value for heat pump customers. But our products might change in line with the energy market – or as we learn more about what our customers need and how they’re using their heat pumps. Right now, there’s no planned end date for Heat Pump Plus. But we’ll let you know in advance if the rate or add-on changes, and we’ll tell you what your options are. You can find out more information in our T&Cs.
We apply credit for Heat Pump Plus to your account in the first 7 working days of each month. It’ll also appear on your monthly OVO bill under Heat Pump Plus Credit.
With Heat Pump Plus, all electricity you use will first be charged at the normal unit rate you pay on your OVO plan. At the end of the month, we work out how much energy you’ve used to power your heat pump. We’ll use this info to credit your energy account in the first 7 working days of the following month. This means your electricity rate to power your heat pump reflects the 15p per kWh rate for Heat Pump Plus. For example:
The Heat Pump Plus rate is 15p per kWh. And let’s say your standard electricity rate is 28p per kWh.
We’ll credit you 13p (the difference between the Heat Pump Plus rate and your standard electricity rate) for each kWh you’ve used to power your heat pump.
And that means, if you use 300kWh powering your heat pump, you’ll get £39 in credit back on your bill.
There are currently no restrictions on customers with Charge Anytime, OVO solar or battery SEG.

1 Actual sum is £350.81. When you add Heat Pump Plus to your plan, your home energy rate will stay the same, but the energy consumed by your heat pump will be charged at an effective rate of 15p per kWh (thanks to payment of your Heat Pump Plus credit). The £350 saving is based on an air source heat pump with a UK average Seasonal Coefficient of Performance (or efficiency rating) of 2.8 and an annual consumption of 3689 kWh with the Heat Pump Plus add-on compared to OVO's average SVT rate of 24.51 per kWh. Actual savings will vary depending on your heat pump usage, efficiency rating and the cost per kWh of your standard home energy tariff. Terms and eligibility criteria apply.
Heat Pump Plus is a new product, and we're currently trialling compatibility with different manufacturers. Availability is currently limited to the first 100 customers with eligible Viessmann heat pumps who sign up. We’ve reached capacity for customers with Mitsubishi Electric Ecodan heat pumps for now. This is so we can review this add-on, and make improvements. There’s no limit on Vaillant heat pump customers. Please see terms and conditions for more information.
