How can you benefit from RHI in Great Britain?

With rising energy bills and worries about energy security, the domestic RHI will help households to receive an income for renewable energy generation, while also achieving financial and carbon savings.

Kingspan Solar are the proven professionals in solar thermal systems and with the new scheme providing long-term payouts to offset the cost of installing low carbon systems, now is the time to be fitting a Kingspan Solar thermal system.

Great Britain Tariff levels

Your RHI tariffs are calculated on the basis of a 7.5% return over 20 years being paid over a seven year period. 

  • Payments are made quarterly in arrears for 7 years
  • Tariffs will change annually in line with RPI
  • Degression will be imposed on reaching published targets.

Who can apply?

The scheme is open to everyone in Great Britain – home owners, social and private landlords, and people who build their own homes. It is available to households both on and off the gas grid.

How do I apply?

You will need to complete a green deal assessment before submitting your application. You can find out more information on the terms and conditions associated with RHI by downloading our brochure. 

The RHI will be administered by the energy industry regulator OFGEM. You will need to sign up to the RHI register and complete an application form. You can find out more information from the OFGEM site

Why Solar Thermal?

Solar thermal is a clean and sustainable method of providing homes with hot water. As with all our Kingspan Solar products, our technology is simple but highly efficient. Typically, a solar thermal system can save you up to 70% on your annual hot water heating costs - so it's good for the planet and good for your wallet!

How much can I earn? 

Households installing solar heating will be paid 19.2 pence per kilowatt hour (kWh) of solar heat generated for the first seven years, index linked. 

For solar thermal systems, the renewable heat generated will be based on the estimate of the system performance completed as part of the MCS installation. The energy generation is calculated at installation time and payments are based on this figure. 

How solar thermal works?

  1. The solar panels collect energy from the sun which increases temperature of the heat transfer fluid contained within the panels.
  2. When the fluid in the panels is hot enough, the pump station circu­lates the hot fluid around the system.
  3. The hot fluid is pumped around the coil at the bottom of the solar cylinder and heats the water that is stored inside.
  4. The colder now fluid returns to the panels where it is reheated by the sun’s energy and the cycle starts again.
  5. The solar controller, which is the brains of the system, enables you to time your hot water, just like a central heating programmer, and measure the amount of energy you have gained from the sun.
  6. If the temperature sensor in the cylinder detects that the solar panel hasn’t collected enough energy to heat the hot water to the required temperature, a supplementary heat source (e.g. gas or oil boiler) is required to top up the temperature of the hot water.
