Boiler upgrade scheme

BUS Launch Key Dates

The dates and key information are as follows:

• 1st April 2022 – Commissioning date – Eligible low carbon heating systems that are commissioned on or after this date will be entitled to support under the scheme.

• 11th April 2022– Account Creation Opens - This enables installers to open an account for the scheme. At this stage businesses will be verified upfront and once an account is set up they will not need to go through this process again. This will make applying for vouchers a smoother process.

• 23rd May 2022 – Voucher Applications Open – Installers will be able to apply for vouchers for grants from this date. They will also be able to redeem them and receive payment once they provide evidence of commissioning.
