Your Savings & Costs

Get paid for heating your home

Fund the ground source heat pump installation costs in your self build project with regular RHI payments from the Government and see what you can save.

The Renewable Heat Incentive (RHI) was introduced by the Government to encourage homeowners, self builders and property renovators to install renewable heating systems, helping to reduce the UK’s carbon emissions.

The RHI will make guaranteed quarterly payments to you every year for 7 years, helping to offset the cost of installing a renewable heating system.

Key RHI Facts for Self Builds & Renovations

  • Guaranteed payments made every 3 months for 7 years based on “deemed” energy consumption – based on figures from your
    Energy Performance Certificate.
  • Government backed scheme, administered by Ofgem. Visit Ofgem’s website for details:
  • 19.55p/kWh tariff for GSHP.
  • All self-build and domestic renovation projects are eligible.
  • Payable on ‘renewable heat’ produced by the GSHP – GSHP’s produce 3 – 4kWh of renewable heat for every 1kWh of electricity consumed.
  • Lower flow temperature heating systems, i.e. underfloor heating, optimise heat pump performance & RHI payments.
  • Index linked tariff increases every year with inflation.
  • Installations must be compliant with the Microgeneration Certification Scheme (MCS) to be eligible.
The money we get back from the RHI more than offsets the capital costs. If it makes economic sense then it would be lunacy not to do it!"
