Grants and Funding

Green Homes Grant

UPDATED 30/09/2020:
Green Home Grant voucher applications are now OPEN!

Under the Greens Homes Grant, homeowners or residential landlords can apply for vouchers worth up to £5,000 and the Government will cover two-thirds of the cost of the work.

Before you apply you must have a quote from a TrustMark-registered tradesperson, to check what measures you’ll be eligible for and to find local installers who can quote for the work follow this link and complete the survey:

Before you apply for the voucher please ensure that you have:

  • the name and date of birth of the property owner or owners
  • the name and date of birth of anyone living in the property who is receiving benefits (if applicable)
  • a quote for the work from a TrustMark-registered tradesperson
  • the TrustMark licence number of your chosen tradesperson

When you are ready to apply for your voucher, please follow this link:

The measures available for install are split into ‘primary’ and ‘secondary’ categories. Households will need to install at least one of the primary measures to qualify for funding, this includes:

  • Insulation: solid wall, cavity wall, under-floor, loft, flat roof, room in roof, park home.
    • Only ‘top-up’ insulation is allowed, for example you can add additional loft insulation to the recommended level, but you cannot replace existing insulation.
  • Low carbon heating: air source heat pump, ground source heat pump and solar thermal.
    • If you are installing low carbon heating then the property will need adequate insulation (e.g. wall and loft), but insulation can be installed at the same time as the heating.

Once one or more of the above measures have been installed you’ll be able to access funding for ‘secondary’ measures. Secondary measures include:

  • Draught proofing
  • Double or triple glazing: only when you are replacing single glazing, you cannot replace existing double glazed windows.
  • Secondary glazing
  • Energy efficient doors: the doors being replaced must have been installed prior to 2002.
  • Heating controls and insulation: appliance thermostats, hot water tank thermostat & insulation, smart heating controls, zone controls, delayed start thermostat and thermostatic radiator valves.

The funding you receive for the primary measures will be the maximum amount of funding you can receive for a secondary measure. For example, if you receive £1,000 towards cavity and loft insulation, you will only receive £1,000 to put towards any secondary measure such as double glazing.


For the main scheme, the following properties are eligible:

  • All owner-occupied homes (including long-leaseholders, shared ownership)
  • Landlords of private rented sector domestic properties
  • Landlords of social sector domestic properties (including LA owned homes)
  • Park home owners (for residential sites including Gypsy and Traveller sites)

New-build domestic properties and non-domestic properties are not eligible, however there has been no immediate guidance as to what classifies as a ‘new-build’. We will update you on this once this information is released.

Low-income Scheme:

There is also a low-income scheme available for those in receipt of certain benefits, or potentially on low income (this is to be confirmed by the Government). These households will be eligible for up to £10,000 worth of funding and they won’t need to pay anything towards the costs of the measures.

Only owner-occupied properties and park homes will be eligible for this scheme and you must be in receipt of an income-based or disability benefit, which includes:

  • Income based Jobseekers allowance (JSA)
  • Income based Employment & Support Allowance (ESA)
  • Income Support (IS)
  • Pension Guarantee Credit
  • Working Tax Credit (WTC)
  • Child Tax Credits (CTC)
  • Universal Credit (UC)
  • Disability Living Allowance (DLA)
  • Personal Independence Payment (PIP)
  • Attendance Allowance
  • Carer’s Allowance
  • Severe Disablement Allowance
  • Industrial Injuries Disablement Benefit
  • Contribution based Jobseekers allowance (JSA)
  • Contribution based Employment & Support Allowance (ESA)
  • Housing benefit

Quality Assurance:

All tradespeople will need to register for the TrustMark or Microgeneration Certification Scheme (MCS) accreditation to offer their services as part of the Green Homes Grant. TrustMark is a government-endorsed quality scheme covering work a consumer chooses to have carried out on their home. MCS is an internationally recognised quality assurance scheme which certifies both products and installation companies to help ensure that Microgeneration products are installed to a high standard.

Households will be offered a list of approved TrustMark and MCS registered tradespeople in their local area to carry out the work. Only approved and accredited installers can be used for the Green Homes Grant to ensure high standard of work and to protect customers. Once the works are agreed, vouchers will start to be issued from the end of September so work can commence.

The government is still setting out further details on how householders will be able to claim the vouchers. Once we get more information about this we’ll send out another newsletter with the latest updates, please sign up here.

Current available funding

Eco Funding

Funding is available for energy efficiency improvements such as loft insulation, cavity wall insulation and heating system replacements through the ECO scheme. Energy Company Obligation (ECO) is a government energy efficiency scheme to help reduce carbon emissions and tackle fuel poverty. ECO funding is available to home owners and some private tenants. We work with installers who have access to ECO funding and can help you during the referral process if you qualify for the scheme.

This funding is available for vulnerable households, this has been defined as a household that is receiving income-related benefits or has a low overall household income and a resident with a vulnerability to the cold. Vulnerabilities can include suffering from a long-term health condition, being in receipt of a non-means tested benefit or living in a property that has a low energy performance. Please contact us to find out more about the eligibility criteria.

Local Funding

We also have access to additional council grants which vary between each Local Authority and have different criteria. The two grants that we manage directly are the Better Housing Better Health grant and the Fuel Poverty Grant.

Buckinghamshire – Better Housing Better Health grant

Grants of up to £2,500 for energy efficiency measures are available for owner occupiers with a resident who suffers from a long-term health condition. Referrals must be made by a health or social care professional, please find the referral form below.

Watford Borough Council can provide incentive grants and loans to Watford residents, regardless of income. This is subject to conditions and funding availability, and is for households deemed appropriate to receive energy measures under this scheme.
