Air Source Heat Pump in a garden of a home

Funding for air source heat pumps is available for people in low income households who currently have electric heating or no heating in their homes. This funding is available from the government as part of ECO4 – the Energy Company Obligations to increase energy efficiency and reduce fuel bills – and the Warm Homes Fund.

Funding for air source heat pumps is also part of the government’s drive to reduce carbon emissions and is available under the Connected for Warmth scheme.

How do you qualify for funding?

At Plumb-Line we are working in conjunction with AgilityEco, who will apply for the funding on your behalf. You may qualify for funding for an air source heat pump, if:

  • You have a total household income of less than £31,000 (after tax) per year,


  • Someone in your household receives one of the following benefits:
  • Child Benefit
  • Child Tax Credit (CTC)
  • Housing Benefit
  • Income Based Jobseekers’ Allowance (JSA)
  • Income Related Employment and Support Allowance (ESA)
  • Universal Credit (UC)
  • Income Support
  • Working Tax Credit (WTC)
  • Pension Credit Guarantee Credit (PCGC)
  • Pension Credit Savings Credit (PCSC).

In addition, your home needs to have electric heaters or no heating and have an energy performance rating of E,F or G.

If your home also requires insulation, then government funding may also be available for this. If so, we can provide and install the insulation for you too.

How does an air source heat pump work?

Air source heat pumps work by extracting heat from the air outside and transferring it to a liquid known as a refrigerant. The refrigerant passes through a compressor, which raises its temperature and it’s then used to heat radiators or under-floor heating pipes and hot water in the home. Air source heat pumps work like fridges in reverse. They are low-carbon heating sources as they use renewable energy from the outside air.
