Green Homes Grant for Homeowners

What green home improvements can I make?

You can visit the Simple Energy Advice’s (SEA) website to see what energy improvements can be made to your home. Just by answering a few questions, you'll find out if you're eligible for a voucher, and see what improvements are suitable for you.
Once you've created your home-improvement plan, you can download this and keep it ready to give to your chosen accredited tradesperson to obtain quotes.
You can apply for the vouchers from the end of September.

What are the benefits of doing improvements?

The aim of the scheme is to cut carbon dioxide production and help homeowners reduce their energy bills - this could mean a generous saving of up to £600 a year. Homes will be made warmer and more energy efficient, which will go a long way towards a green recovery and a cleaner environment. The additional benefit will give much-needed support to over 100,000 jobs in the industry.

What are the primary and secondary measures? 

The available measures are split into ‘primary’ and ‘secondary’ categories. Households will need to install at least one of the qualifying primary measures to be able to use the voucher on any secondary measures. The secondary measure will be subsidised up to the subsidy value of the primary measure, e.g. if a household receives £1,000 for primary measures, they will receive a maximum of £1,000 towards the secondary.
