Funding, Savings & Costs

With reduced heating bills, lower carbon emissions, and a guaranteed return through the Government’s Renewable Heat Incentive, buying a ground source heat pump for your self build or renovation is an investment that will pay for itself.

The RHI

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.

RHI facts

  • All self-build and domestic renovation projects are eligible;
  • Government scheme administered by Ofgem;
  • Guaranteed payments made every 3 months for 7 years based on “deemed” energy consumption (based on figures from your Energy Performance Certificate);
  • 19.55p/kWh tariff;
  • Index linked tariff increases every year with inflation;
  • Payable on ‘renewable heat’ produced by the ground source heat pump (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 and can increase RHI payments as a result;
  • Installations must be compliant with the Microgeneration Certification Scheme (MCS) to be eligible.

Boost your RHI & savings

To boost your RHI returns and further lower your energy bills, Kensa will advise you on how to make yor installation as efficient as possible.

Here are some quick recommendations:

Insulation

The better insulated your home the more efficient it is to heat. Your home’s efficiency will also impact the size of the heating system you require – the lower your heat demand the smaller and cheaper the ground source heat pump and ground array, with less work to do, producing a greater proportion of renewable heat, which all in all means a far cheaper to run home with more RHI income.

If a heat pump is too small for the property then running costs will increase, too large and the heat pump could cycle on and off. Both scenarios are costly and inefficient for you and the RHI.

MCS sizing

Kensa requires a full MCS heat loss calculation for all project to determine the accurate heat pump and ground array size required. Kensa will undertake this service for £150 – £200 depending on the project’s scale.

For complete peace-of-mind, Kensa’s MCS Umbrella service includes a full MCS heat loss calculation in addition to many other benefits, or if you have an MCS approved installer, they will take care of this for you.

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!"
