We have successfully secured multiple rounds of Green Homes Grant Local Authority Delivery funding  to assist Hertsmere residents in making their homes warm, comfortable and energy efficient.

Sustainable Warmth

Sustainable Warmth is a new Government grant scheme designed to fund energy-efficiency upgrades to residents who are most likely to be impacted by the high cost of rising bills. These improvements will help residents to use less energy and spend less on their energy bills. 

How it helps:

  • Energy saving tech and upgrades installed by approved installers
  • Creating warmer, healthier homes
  • Helping to cut carbon emissions
  • Funding available for homes on and off the gas grid

The energy-efficiency grants will cover a range of energy-saving home improvements designed to balance the needs of residents with carbon reduction and grant availability.

If you think you might qualify, please register your interest at: Sustainable Warmth Scheme

What energy saving improvements can I get for my home?

Energy and cost-saving upgrades that you may be able to get for your home: 

  • Insulation and ventilation upgrades
  • An upgrade to a low carbon heating system (the new heating system cannot include a gas or oil boiler)
  • Heating Controls
  • Solar PV (that generates free electricity)
  • Energy Efficient lighting


How much funding is available?

Owner occupiers: For homes connected to the gas grid, the grant is up to £10,000.  For homes not connected to the gas grid, the grant is on a sliding scale, from £10,000 to £25,000. The exact amount available is dependent on the Energy Performance Certificate (EPC) of the home and the fuel source that heats the home currently (the EPC can be determined by the programme if it is unknown). 

Privately rented properties: To qualify the tenant must meet the income eligibility and the landlord will need to contribute a minimum of one third towards the cost of the upgrades in addition to the grant provided.

For privately rented properties connected to the gas grid, the grant is up to £5000.  For privately rented properties not connected to the gas grid, the grant is on a sliding scale, from £10,000 to £16,666.  The exact amount available is dependent on the EPC of the home and the fuel source that heats the home currently. 

If overall costs exceed the maximum grant available, additional investment by the landlord will be required.  Costs and the contributions expected from the landlord will be agreed prior to commencement of work.

Who is eligible? 

To be eligible for Sustainable Warmth Funding the following criteria must be met:

  1.  The household must be a private domestic dwelling in England with an EPC rating of E, F or G. There is a 30% cap on Band D properties, and with high interest in the scheme and a high proportion of D rated properties put forward already, you may be placed on a waiting list if your home is D rated.  If your property’s EPC is unknown, it can be determined by the programme.
  2. The household must have one either i) a household income of no more than £30,000 (before tax or any other deductions) ii) an equivalent income where cost of living is below £20,000 (i.e. after rent or mortgage costs) iii) a household composition (e.g. number of dependents) which stretches income to a position where they would be in fuel poverty.

The scheme opened on 1 April 2022 to private tenants/landlords and homeowners, who can check their eligibility by calling 0808 196 8255 or through online application to the Sustainable Warmth scheme.
