Boiler Upgrade Scheme (BUS)

Sign into your Boiler Upgrade Scheme installer account

Due to essential maintenance being carried out, the Boiler Upgrade Scheme Installer portal will be unavailable from 12:30pm to 2pm on Tuesday 20 October.

Create your GOV.UK One Login account  

From 3 November 2026 you will require a GOV.UK One Login account to access the Boiler Upgrade Scheme installer account area. You can create your GOV.UK One Login account ahead of this date.  

For new installers on the scheme 

For installers joining the scheme for the first time, you must create your GOV.UK One Login before creating a BUS Installer account. You must use the same email address for both. 

For existing installers on the scheme 

To create a GOV.UK One Login account you will need the same email address you used to register with the Boiler Upgrade Scheme and a UK mobile phone number or authenticator app.  

Create your Boiler Upgrade Scheme Installer account 

Once you have created your GOV.UK One Login, you will need a verified BUS installer account for your business. 

To create your installer account, you will require: 

• MCS certification 
• identification 
• proof of home address 
• evidence of business bank account  

You need to download and complete the Installer account form and email this to BUS.accountcreation@ofgem.gov.uk. 

Please refer to  chapter 4 of the installer guidance for further detail on creating an installer account. 

After we have created your installer account, each user will receive an email invite to use the scheme online. 

You can add multiple users to this account so they can apply for and redeem BUS vouchers on behalf of the business. Each user will need their own individual GOV.UK One Login account to access the BUS installer portal. 

Once you are set up with an installer account 

In your installer account you can: 

• apply for BUS vouchers 
• find out how to redeem BUS vouchers 
• check the status of your voucher applications and voucher redemption applications 

 We will sign you out if you stay on a single page for more than 60 minutes. 

Who can create an installer account 

The person who creates the account must: 

• have the legal authority to act on behalf of the business 
• agree to be the business’s 'authorised representative' for the scheme. 

An 'authorised representative' is someone whose identity we have checked and who is Ofgem’s first point of contact should we ever need to speak to someone about the account. 

If your business is a limited company, the person creating the account must be a company officer (e.g. director or secretary) who is listed on the Companies House register. 

If you are a sole trader, you will not be registered on Companies House. However, we will still need to check your identity. 

Update information on an existing installer account 

Only authorised representatives can change business information on a BUS installer account.  

You can submit a request to change the following information via your business’s BUS installer account area: 

• business information, such as registered name, office address, trading name, and trading address 
• details about the authorised representative, including telling us you want to replace the existing authorised representative with a new one 
• MCS certification number, including adding a new certification number.  

You can submit a request to change the following information by downloading and completing the appropriate account amendment form and emailing it along with any supporting evidence, to BUS.accountcreation@ofgem.gov.uk. 

• bank details BUS voucher grants are paid into 
• edit the email address of an authorised representative - this can only be accepted from the current authorised representative 
• update your consumer code membership details 

Users with 'user management' permission can add, edit, or remove any users (apart from the authorised representative) associated with an installer account via your business’s BUS installer account area. 

Apply for a BUS voucher 

You can apply for BUS vouchers online. 

You must do this from your business’s BUS installer account area. 

You will be able to access this account area after: 

• your business’s BUS installer account has been created 
• we have sent you an invite email 
• you have created your personal sign-in details (using the link in the invite email). 

You can also use the account area to track the progress of all your business’s voucher applications and voucher redemption applications. 

If you do not have your own sign-in details yet 

Someone in your business will need to set you up to use the scheme. Talk to the person who initially created the installer account or anyone at your business who has permission to manage users on the account. After you are added to your business’s BUS installer account, you will receive an invite email to get set up. 

If you are unable to use the online service 

Contact GOV.UK One Login support directly if you need advice on setting up, or accessing, your GOV.UK One Login.  

For questions relating to your Boiler Upgrade Scheme installer account, email BUS.Enquiry@ofgem.gov.uk or call 0330 053 2006. 

Redeem a BUS voucher 

As an installer, after you have commissioned the new heating system, you can apply to redeem your BUS voucher. 

You must do this from your business's BUS installer account area.  

Cancel a BUS application or voucher 

You can cancel 

• a BUS voucher application that you have submitted 
• a BUS voucher that has been issued 
• a BUS redemption application 

You can do this from your BUS installer account area.
