Introducing Heat Pump Plus

Vaillant & OVO have partnered to help you offer reduced heat pump running costs for your customers.

Your customers can switch to OVO and save up to £300 a year* with Heat Pump Plus

Heat Pump Plus is a free type of use add-on for new and existing OVO customers in the UK** who also have a Vaillant ‘connected heat pump’. Heat Pump Plus is available for both new and previous air source heat pump installations.

This industry first type of use add-on helps your customers save money on the cost of electricity used to operate the heat pump, with a 15p per kWh rate when they are an OVO customer.

By using Heat Pump Plus to power a Vaillant heat pump at 15p per kWh compared to a standard variable tariff of 23p per kWh, your customers could save up to £300 a year on their energy bills*

How does your customer get Heat Pump Plus?

Your customer will need to switch to OVO for their electricity supply

If they are not already with OVO, they can get a quote and create an OVO account***.

Must have a smart meter installed

It must send half-hourly readings and your customer can have one installed for free through OVO.

Have the following Vaillant products installed at their home:

aroTHERM oraroTHERM plus air source heat pump

myVAILLANT connect internet gateway


sensoCOMFORT heating control

If you’ve installed a heat pump but didn’t fit the other necessary products to get a ‘connected heat pump’, you will need to install the additional items for your customers so that they can apply to become an OVO customer and access the Heat Pump Plus add-on.

How does it work for my customers?

When your customer has signed up to Heat Pump Plus, all the electricity they use will first be charged at the normal rate they pay on their OVO account. Your customer will pay one rate for the electricity in their home and have a lower rate for the electricity the heat pump uses.

With the Vaillant heat pump being connected, OVO can view the heat pump usage. The money saved will then be added as credit in your customer’s energy account in the first 7 working days of the following month.

Why should my customers sign up for Heat Pump Plus?

As more homeowners across the UK are opting for a low carbon heating solution, we’re proudly supporting our installers by providing you with a great solution to help more of your customers choose a Vaillant heat pump, paired with our connected controls to create a smart home heating system.

I fit Vaillant heat pumps – Can I offer Heat Pump Plus to my customers?

Yes, once you’ve installed the heat pump in your customer’s home, you must also fit myVAILLANT connect and a senso control with the myVAILLANT app. This means they can adjust their heating via their mobile phone. Once installed your customer can then sign up to OVO for their energy and they will be offered the Heat Pump Plus type of use add on.
