The Green Homes Grant is a government-funded scheme that aims to help UK homeowners and landlords pay for energy-efficient improvements to their home.

The Green Home Grant can issue vouchers to homeowners and landlords up to a value of £5,000 to cover up to two-thirds of the costs for making pre-approved energy-efficient home improvements.

And, if you’re a homeowner in receipt of certain benefits, you could be entitled to 100% of the costs, up to a value of £10,000.

So this Government’s ‘eco home’ funding grant could really help you save money on energy bills by making your home much more energy efficient.

With so many of us using more home energy due to lockdown restrictions and with a predicted hike in energy prices next April, I’m sure there are many of you that hope to apply for such an invaluable grant.

Who is eligible for the Green Homes Grant?

You may be eligible for a green homes grant if you:

  • Reside in the UK
  • Own your home or have a long lease or part-own a shared ownership home
  • own a park home on a residential, travellers’ or gypsy site
  • are a private or social residential landlord

You are not eligible for a Green Homes Grant if you own a brand new, newbuild home which has never been occupied.

Is the Green Homes Grant means-tested?

Homeowners and landlords do not have to be means tested to be entitled to a green homes grant. However, a non-means-tested grant will only cover up to two-thirds of the cost of eligible improvements up to a maximum of £5,000.

But, if you are a homeowner on a low income and are in receipt of certain benefits, you can be means-tested to see whether you’re eligible for a grant to cover 100% of the costs of eligible home improvements, up to a maximum of £10,000.

Can I get a new boiler on the Green Homes Grant?

No, you cannot get a new boiler on the Green Homes Grant Scheme. However, you could qualify for a new free boiler under the Government’s ECO Scheme or at least receive financial help towards the cost of a new boiler.

Incidentally, if your boiler breaks down, most standard home insurance policies do not cover emergency repairs to a boiler or for the replacement of a boiler.

So if your boiler is very old, you should seriously consider applying for a free boiler replacement grant and/or consider taking out a boiler breakdown insurance policy.

For more details, take a look at our guide that fully explains the free boiler replacement grant.
