Green Homes Grant

A £2 billion Green Homes Grant, intended to make homes more energy efficient, is now live. The scheme allows for 600,000 homes in England and Wales to receive grants for making thermal performance and energy saving measures. This is open to homeowners and landlords and will allow them to claim for vouchers worth up to £5,000 or £10,000 for low income households.​​​​​​​

These primary home improvements could include installing a solid wall insulation system to reduce heat loss, or converting to a biomass boiler to reduce the amount of carbon dioxide a home produces. As well as covering primary measures, the grant is also available for secondary measures such as draught proofing, installing double or triple glazing (when replacing single glazing) or smart heating controls.

It is important to note the vouchers must be used to install at least one of the primary measures, if you choose to do this you can then use the vouchers to help cover the cost of secondary measures. The value of the secondary measure vouchers is capped at the value of the primary measure. Find out what’s included in primary and secondary measures.

The government will provide vouchers to cover the cost of up to two thirds of the home improvement measure. The value of the vouchers is capped at £5,000 or £10,000 for low income households or those receiving benefits. The tradesperson installing the solution will receive payment from the government for the value of the vouchers.

    Preparing a client estimate

    We know preparing estimates can take time and you need to make sure everything is correct otherwise you could be out of pocket.

    Through our sister brand Build Aviator, we can prepare all your Green Homes estimates, taking into account local product prices, labour rates and produce a list of materials to meet the system specification or use our own Registered Construction Details. All materials can then be purchased through your local Jewson branch. Even better, Green Homes Grant estimates are FREE for PAS 2030, TrustMark approved Jewson account customers for only £50 ex VAT. for non-Jewson account customers.

    Simply upload the energy plan your customer sent you from Simple Energy Advice and we will have your estimate back within three working days.

    Having the right products

    It is crucial you install the right products in line with the specified system designs and Registered Construction Details. We ensure we stock the right products to match the system, as well as working with Local Authority Building Control (LABC) to match our Registered Construction Details (RCDs) with the products you need.

    Registered Construction Details (RCDs) are used to ‘design out’ cold spots and overcome thermal bridging. Thermal bridging occurs at junctions where adjoining surfaces have different insulation values (around windows, for example).

    We’ve teamed up with LABC to match over 15,000 compliant products with the 368 construction details. This makes choosing a solution for minimising heat loss much simpler, as every recommended product will make your build compliant with Building Regulations.

    What’s next?

    1. Once you have picked the energy-saving measure, download your plan from Simple Energy Advice and then find a certified installer in your local area here
    2. Once you have your quote, visit from the end of September to upload your quote and apply for your vouchers. 
    3. Once the application is approved, you can book in the tradesperson to carry out. 

    What does the homeowner pay?

    For example, if a homeowner of a semi-detached or end-terrace installed cavity wall and floor insulation, costing around £4,000, the homeowner would pay just £1,320 – with the government paying £2,680. The owner could save over £200 annually on their bills and reduce their carbon footprint by cutting 700 kg of CO2 a year from their home alone.
