Green Homes Grant: The best ways to use the government green grant

By installing eco-friendly home improvements in your home, you can reduce your carbon footprint and your energy bills at the same time. With the government’s Green Homes Grant now offering you up to £5,000 (or £10,000 if you’re on a low income) to install green upgrades until 31st March 2022, there’s no better time to greenify your home.

Here are our top dos and don’ts for using the Green Homes Grant to help make sure you’re happy with the work that’s done in your home.

DON’T use a tradesperson that’s not fully registered for the Green Homes Grant 2020

The government has stated that all tradespeople completing Green Homes Grant work must be:

  • Registered to be a Green Homes Grant installer.
  • A TrustMark registered business.
  • Accredited by the Microgeneration Certification Scheme (MCS) if they’re installing low carbon heat measures.
  • Able to meet the government’s PAS standards, which are minimum PAS2030 for all green improvements, and PAS2035 for park homes, high rise buildings and buildings that are traditionally constructed and protected.

TrustMark is a government-endorsed quality scheme. It requires all registered tradespeople to have their work regularly inspected, meet high levels of competence and show that they’re committed to good customer care. MCS is an industry-led quality assurance scheme – all certified tradespeople have to show that they meet the industry’s standards of quality, competency and compliance. With these two quality schemes, you can know that your tradesperson will complete the job safely and to a high standard.

You can find fully registered Green Homes Grant installers on Rated People. Plus, we screen all the tradespeople that apply to join our platform, and we work with Action Fraud and Trading Standards, so that the risk of you hiring a rogue trader is minimised.

DO ask the tradesperson if they’re fully registered for the government green grant

When you’re looking at a tradesperson’s profile on Rated People, keep an eye out for their ‘Certifications’ section. We display all of their membership badges there, including a TrustMark badge (if they’re registered).

DON’T forget to use your UK Green Homes Grant scheme voucher before it expires

Your voucher will be valid for 3 months from the date it’s issued, or until 31st March 2022. You can ask for a voucher extension at any time before your voucher expires – unless the scheme is closed.

Remember, you can get up to £5,000 for your green improvements, or £10,000 if you’re on a low income. If the work costs more than your voucher’s worth, then you’ll have to pay for the rest.

DO speak to a tradesperson for specific advice for your property

Ask an Expert page on the Rated People website

Maybe you’re unsure which green home improvement you want, or you’re looking for more information on a specific green improvement. Whatever you’re looking for, it’s best to ask a tradesperson for advice – ask your question directly to an expert, for free.

DON’T forget that you need to have one of the primary measures installed to be eligible for the secondary measures

The government has stated that your voucher for your secondary measures will be worth up to the same amount as the voucher you got for your primary measures. The measures are:


  • Wall, floor and roof insulation.
  • Low carbon heating, such as heat pumps.


  • Windows and doors: Upgrading to double/triple glazing or more energy efficient doors.
  • Heating controls and insulation.
