Boiler Upgrade Scheme

What is the Boiler Upgrade Scheme?

The Boiler Upgrade Scheme (BUS) is the UK's latest grant scheme for low carbon heating. Following on from the successful RHI scheme, the boiler upgrade scheme will be an upfront voucher to contribute to the cost of installing a low carbon heat pump heating system. The value of the voucher will depend on the type of heat pump being installed, either a £5000 voucher for an air source heat pump or a £6000 voucher for a ground source heat pump. 

How will the process work? 

The grant application process will be straight forward for the customer. Firstly, they should engage with an MCS registered installer and obtain a quote. Once they are happy with the quote, they should confirmed that with the installer and ask them to begin the process. The MCS installer will then submit the application to the Ofgem, who will contact the customer to attain consent for the application to begin. The installer will then be ready to install the system. Once the system has been installed and both parties are happy, the customer should pay the installer - minus their voucher value. The installer will then inform Ofgem that the installation has been completed, where their final bill will be cleared via the voucher. 

Am I eligible for the Boiler Upgrade Scheme? 

A property is eligible where...

  • it is a dwelling or a non-domestic property,

  • it is not social housing,

  • if it was, or will be, first occupied or used (whether as a dwelling or as a non-domestic property) before the date on which a heat pump or biomass boiler (subject to conditions) is commissioned.

Prior to the installation and commission of the new system, the property must have a fossil fuel or electrically heated system (excluding heat pumps) providing space heating or water heating.

How do I get started?

Press the "get a quote" button and complete the short form. Our team will arrange video/phone call with you to discuss your property, your eligibility and answer any questions you may have. After this, we will visit your property to conduct a full heat loss survey. This survey will tell us the following information: 


  • Room-by-room heat loss

  • Room-by-room heat demand

  • Heat pump size needed

  • Radiator sizes needed

  • Insulation needed (if any)

  • Properties suitability for a heat pump 

After this, you will receive a full quote from our MCS accredited installer. You can then decide whether you would like to proceed with the grant application or not. 


Do I have to pay for the survey? 

In most cases our heat loss survey will be a completely free no obligations survey. However, if the property is particularly large, or complex, then a payment may be requested due to the time it takes our team to complete the survey and finalise the data in the office. However, the customer will be notified of any potential payments before the survey has been booked in, so this can be cancelled if the customer is not happy to pay.
