Sustainable Warmth grant funding

Sustainable Warmth is a new government grant scheme which provides funding for low income households to upgrade energy inefficient homes.

Low income households can apply for funding to install a range of energy saving improvements to reduce energy use, make homes warmer and healthier, and keep energy costs under control.

These upgrades will reduce climate changing carbon emissions so are also good for the environment.

What energy improvements can be made?

Under the scheme you may be eligible for:

  • Improvements to insulation (loft, cavity and wall) and ventilation
  • Upgrades to a low-carbon heating system, for example replacing a gas or oil boiler with an air source heat pump (the new heating system cannot include a gas or oil boiler)
  • Heating controls
  • Solar PV panels to generate electricity
  • Energy efficient lighting

Approved installers are used. Homeowners do not have to contribute to any costs or pay back the grant afterwards. Tenants and landlords can also apply for funding.

What grants are available?

Sustainable Warmth funding is available for homes on or off mains gas. The grants available are:

Owner occupied properties

  • For eligible households on mains gas, grants are available of up to £10,000.  
  • For homes not connected to mains gas, the grant is on a sliding scale from £10,000 to £25,000.

Privately rented properties

To qualify, tenants must meet the income eligibility and the landlord will need to contribute a minimum of one third towards the cost of the upgrades.

For privately rented properties connected to mains gas, the grant is up to £5,000. 

For properties not connected to mains gas, the grant is on a sliding scale, from £10,000 to £16,666.  If costs exceed the maximum grant available, additional investment by the landlord is required. 

Grant eligibility 

To be eligible for Sustainable Warmth funding:

  • Your household must be privately owned (either by yourself or a landlord) with an Energy Performance Certificate (EPC) rating of E, F or G. Some D rated properties may also be considered.


  • Have an annual household income - including any benefits you may receive - of under £30,000 (before tax and deductions) or under £20,000 (after rent or mortgage costs have been deducted).

The number of children in your household will also be considered and any recent loss of income.

How can I apply for funding?

Sustainable Warmth is being administered by City Energy on behalf of the district council.

Grants are provided on a first-come, first-served basis. You can apply online to see if you are eligible: or call City Energy’s customer care team on: 02921 680951.

A free home survey will be arranged. The EPC of your home will be produced and this will determine whether your property is suitable. The grant amount depends on the EPC and how your home is currently heated.
