Domestic Renewable heat incentive
What Is The Domestic RHI?
The Domestic Renewable Heat Incentive ("Domestic RHI") is a Government financial support scheme for renewable heating systems including ground source heat pumps and air source heat pumps. The scheme was launched in April 2014 and is administered by Ofgem, the energy regulator. The purpose of the Domestic RHI is to support and reward those households who move away from traditional fossil fuels for heating their homes, which helps towards the Government's renewable energy and carbon reduction targets.
Owners of heat pumps will be paid quarterly over a 7 year period for all of the eligible renewable heat generated by the heat pump in the property. Eligible renewable heat includes the energy required for heating the home and providing domestic hot water.
Payments are usually based on a deemed amount of heat produced by the heat pump, and are index-linked, meaning payments should increase year on year.
How Is The Domestic RHI Worked Out?
Domestic RHI HEAT Pump TARIFFS
The Domestic RHI is a tariff based system. The table below shows the current Domestic RHI tariffs for ground source heat pumps and air source heat pumps. These tariffs represent the amount you receive for each unit of renewable heat generated by your heat pump to heat your home.
|Technology||RHI Tariff [p/kWh]|
|Ground Source Heat Pump||20.89|
|Air Source Heat Pump||10.71|
Table showing RHI Tariffs applicable from 01/04/2019 - 30/06/2019
For a typical 4-bedroom detached house
Total space heating and hot water requirement - 20,000kWh per annum
Ground source heat pump system capacity - 11kW
Ground Source Heat Pump Seasonal Coefficient of Performance - 3.5
This means that for each unit of electricity consumed, the heat pump produces 3.5 units of heat. The "renewable heat" is the difference between the total heat output and the electricity input. So for this example, for every 3.5 units of heat produced, 2.5 units are classed as "renewable heat".
Renewable Heat = 20,000kWh x (2.5 ÷ 3.5) = 20,000kWh x 71% = 14,286kWh @ 20.89p/kWh = £2,923 per annum
TOTAL ANNUAL DOMESTIC RHI PAYMENT = £2,984 PER ANNUM
Over 7 years the Total RHI Payment exceeds £20,000

Domestic vs Non-Domestic RHI
Domestic Renewable Heat Incentive
Generally speaking, the Domestic RHI is applied where a single property, which can receive a domestic Energy Performance Certificate (EPC), is being heated by a renewable heating system. The EPC acts as proof to show that the property is assessed as a domestic dwelling, as well as provided the deemed heat requirement for the property on which the payments are based.
NON-DOmestic renewable heat incentive
If the renewable heating system is to be heating a commercial, public or industrial premises, or a heat pump system is delivering heat to multiple residential premises, then you would need to apply for the Non-Domestic RHI. This can include the likes of schools, hospitals, churches, large or small businesses, as well as multi-residential buildings.
Making A Claim
First things first...
Before you make a start at claiming for the Domestic RHI, please ensure you have the following at hand:
Your Microgeneration Certification Scheme (MCS) certificate number
Your Energy Performance Certificate (EPC) number
Your bank details - make sure that the name and personal details you use for your application are the same as on your bank account
Your metering questions, if you need to be metered
It is also recommended to prepare the following:
If you need to be metered for payments please have your "Metering Questions" provided by your installer to hand
Invoices stating both the cost of the system and labour to install - this will have no effect on payments or eligibility
Once you have all of the above at hand, click here and select Apply Now.
Using the help sheet, fill in each block. If you do still require any further assistance, Contact Us and we will be happy to advise.
After Your Application
Once you have made your application you will be able to log in to MyRHI which you will be able to keep track of your RHI payments, when you are likely to receive your payments and check your bank details to ensure the payments are being made to the right account. Then you can sit back, relax and watch the payments roll in for the next 7 years while experiencing the advantages of using a renewable heat source.
