Green Homes Grant

The Government’s Green Homes Grant is a great opportunity to get some financial help towards making your home more energy efficient – but how do you work out if you are eligible and if your home is suitable for any of the improvements? 



Can you tell me more about the Green Homes Grant?

The Green Homes Grant scheme was announced in July as part of the Government’s Plan for Jobs.  It is open to homeowners and landlords, who can apply for vouchers towards the cost of energy efficiency improvements.

The vouchers will cover up to two thirds of the cost of the improvements, up to a maximum of £5,000.  If you receive certain means tested benefits, you could get a voucher that covers all the costs of your improvements, up to a maximum of £10,000


What can I spend the grant on? 

Two categories of improvements have been created.  You will be able to apply for a voucher to install one or more of the following ‘primary’ measures:

  • Solid wall insulation, cavity wall insulation, under-floor insulation or roof insulation (including loft, flat roof and room-in-roof) and park home insulation

  • Air source heat pump or ground source heat pump

  • Solar thermal heating

In addition to one of the above, you can use your voucher for one or more improvement on the ‘secondary measures’ list.  The cost of the secondary measure cannot be greater than the cost of the primary measure:

  • Draught proofing

  • Replacing single glazing with double/triple glazing or installing secondary glazing

  • Upgrading doors (installed before 2002) with energy efficient replacements

  • Hot water tank insulation

  • A range of heating controls – including hot water tank thermostats, thermostatic radiator valves and smart heating controls.

We can help you understand which of these various measures suit your home best. Every home is different, and many factors affect what can most improve comfort and energy efficiency. 

It is important that all improvements are designed and specified correctly, both individually but also alongside any existing or new energy efficiency measures in your home.  It is also crucial that the improvements are installed correctly.

Details on available measures and eligibility for the low income scheme can be found here


How can I get a grant?

You must apply for a grant from the government

Make sure that you read the Terms & Conditions in full - they explain in detail how the process works and what you and your chosen installer need to do.  

If you live in Sussex, Warmer Sussex can support you in making decisions: what eligible Green Homes Grant measures are suitable for you home and which accredited contractors to use.


What can I do now?

You can use the Warmer Sussex Plan Builder to start getting an idea of the best options for your home and the likely costs, then get in touch with us. 

Or you can simply send us your details  and we’ll arrange an appointment for a home survey and Warmer Sussex Whole House Plan, which will show you what energy efficiency improvements best suit your home and which would have the biggest impact.  Your retrofit coordinator will steer you through which options are eligible for the grant.

We can then get you up to three quotations and help you plan the works with local contractors who are members of our cooperative and those accredited to carry out work funded by the Green Homes Grant.

We also provide expert support for the contractors doing work to your home, meaning that the works you have done really deliver you the benefits they should.  

Remember: the only tradespeople able to do work paid with Green Homes Grant vouchers are those registered with Trustmark and either PAS2030 accredited or a member of the Microgeneration Certification Scheme (MCS).
