Boiler Upgrade Scheme Self-Build Process: Understanding Qualification Criteria 

June 18, 2024

The Boiler Upgrade Scheme (BUS) consists of 2 ways property owners are able to qualify for the grant, the first is well known but the second may be applicable if the house does not have an EPC because it had recently been built.

VitoEnergy operates as an installer, consultant and MCS umbrella, supporting both homeowners and engineers across the UK.


EPC Qualification for Boiler Upgrade Scheme: Eligibility Criteria and Requirements

The most common way people use to qualify for the BUS is using their properties Energy Performance Certificate (EPC). In order for an EPC to be eligible for the grant, it must show no recommendations for loft or cavity wall insulation.

It is worth noting that as this is the Boiler Upgrade Scheme, the EPC should show that the current heating is provided by a boiler, this also could be electric heating but it cannot be heated by a heat pump.

This route is open to both domestic home owners, landlords and commercial property owners.


A less common and perhaps less understood method to claim for the grant is by proving the property is a self-build, new build properties owned by a business or organisation are not eligible for the scheme but for a developer who is planning on living in the house it is a valid route.  What we need to provide evidence of in this case is the property’s title deeds and relevant invoices to show the home owners have funded the build themselves.

The self-build application process is actually very simple. The necessary documents are needed prior to the application being completed as they have to be submitted with the application (this is a new rule which has only recently been brought into place as previously, Ofgem would ask for the title deeds and invoices once they have received and looked over the application). 

Previous heating systems are also crucial information. For most self-build customers, the heat pump is the first heating system the property has had, however this is not always the case. The customer should also make us aware if they are currently staying at a different property as Ofgem questions where the customer abides. We will complete the application 3 weeks prior to the heat pump installation starting, the customer will receive an email from Ofgem which needs to have consent for us working on their behalf. Ofgem might also get in touch with the customer if they request to see additional invoices or have trouble verifying their identification. Once the application has been accepted, it can be redeemed as long as the Microgeneration Certification Scheme (MCS) has been completed after the installation.

Essential Documentation for Self-Build Applicants

Ofgem accept the larger invoices in regards to self-builds - these being ones for framework, foundations, bricks and even labour. It is advisable to provide as many invoices as possible- this way Ofgem will be less likely to get back in touch as this can slow the process down. They do not accept invoices for doors, windows, kitchen units etc (presumably as these could be for a renovation?).

How to Obtain Title Deeds

Title deeds

Examples of title deeds are contracts of sale, lease agreements, mortgage documents or conveyancing records. These documents show ownership of a property. They can be accessed through the Land Registry UK website - Land Registry UK - Access Land Registry Title Documents Online.

We have often dealt with customers who were (understandably) unsure how they could access their title deeds. 

The step by step guide is as follows;

  1. Verify if the property is registered with the Land Registry.
  2. If the property is registered, you can download a copy of the title deeds.
  3. If the register shows the deeds are marked as ‘filed’, this means there is a scanned copy of the deeds under Land Registry. A deeds request form can be filled out in this case, using the properties title number from the title register. 
  4. Submit your completed form and payment to the Land Registry to receive your title deeds.

“I explained the process over the phone and followed up with an email repeating what I had told them - this way they have something to refer back to. They received their deeds, sent them to me over email and their BUS application was begun right away. They couldn't have been happier with the process and were very grateful that they had been given a step by step guide.”
