Guidance

Become a Green Homes Grant installer

How to carry out work under the Green Homes Grant scheme if you are a tradesperson or business.

The Green Homes Grant scheme allows homeowners and residential landlords to apply for a voucher towards the cost of installing energy efficient improvements to their home.

Vouchers will cover two-thirds of the cost of eligible improvements, up to a maximum government contribution of £5,000 or £10,000 if the household is on low income.

To carry out work under the scheme, all tradespeople and businesses will need to be certified to install energy efficiency measures and register to take part in the scheme.

Eligibility

If you install energy efficiency measures, you must be certified to install measures against Publicly Available Specification (PAS) standards:

  • PAS 2030:2017
  • PAS 2030:2019
  • PAS 2035:2019 (for park homes, high rise buildings and buildings that are both traditionally constructed and protected)

You must be certified by a body that has been accredited by the United Kingdom Accreditation Service (UKAS).

If you install low carbon heat measures such as heat pumps, you must be certified with the Microgeneration Certification Scheme (MCS).

Only TrustMark-registered businesses can register to be a Green Homes Grant installer.

If at any point you lose your certification or your TrustMark approval you must notify the scheme administrator.

How to apply

  1. Register as a certified installer with TrustMark

    You will be added to a directory of certified installers, where homeowners can contact you to get a quote.

  2. Register to be a Green Homes Grant installer

    You will be asked to sign up to the Terms and Conditions of the scheme and provide your company’s details for payment. You will need to register for each of the scheme’s measures you are planning to carry out.

You must have received confirmation that your registration has been successful before you offer to carry out any work under the scheme.

Giving a quote

The price quoted should reflect the total costs of the installation including materials, labour and VAT. It should be your usual price and not be higher than the price you would have quoted if the installation was not being carried out under the scheme.

You should not commit to start any work until the customer’s application has been approved and they have been issued with a voucher.

If approved, the voucher will contain your or your business’s name after the customer has selected you to carry out the work.

Vouchers cannot be used to help pay for works that were carried out before the voucher was issued.

Doing the work

You can only begin work once the voucher has been issued to the customer. Any work that was started before that date cannot be claimed under the scheme.

We will start to issue vouchers to customers from early November 2020.

The work must be completed and the voucher redeemed by the customer before the expiry date of the voucher. Vouchers expire after 3 months or on 31 March 2021, whichever is earlier.

Customers can apply to extend the voucher before it expires, as long as the scheme has not been closed.

Payment

You will be paid for the costs covered by the voucher once the work has been completed and you have confirmed you have received any customer contribution. The payment will come from the grant administrator. Most installers will get the grant payment within 5 working days.

Where a customer contribution is required, the customer contribution is a condition of voucher eligibility. Accepting non-payment to secure the work - or paying this yourself - will make the voucher invalid and constitute fraud.
