If you join the RHI scheme – and stick to the rules (see below) – you’ll get paid for the amount of renewable heat your system produces. The payments will be made four times a year over seven years.
The payments you receive will also be determined by the type of renewable system you have.
You can use one of the government's Renewable Heat Incentive Calculators to find out how much money you could get through the Renewable Heat Incentive.
There is a RHI calculator for England and Wales, and one for the Renewable Heat Incentive Scotland.
You're also likely to have more money in your pocket through the savings you make on your energy bill. After all, you'll be generating some of your own energy once your renewable heating technology is installed.
What are RHI tariffs?
Your RHI tariff sets the amount you get paid for the energy you produce. It's based on the type of renewable heating you have, as well as other factors.
Your tariff rate is updated every April by the Department for Business, Energy and Industrial Strategy (BEIS). This is done to keep it in line with the Retail Prices Index (RPI) or Consumer Prices Index (CPI).
What rules do you have to follow to get RHI payments?
- You'll need a Microgeneration Certification Scheme (MCS) certificate for your heating system (check the MCS product directory for RHI air source heat pumps, RHI biomass boilers and stoves, and other eligible products).
- You'll need a domestic Energy Performance Certificate (EPC), which is less than 24 months old when you submit your application. The Landmark Register (England and Wales) or Scottish EPC Register will tell you if you have an EPC. If your EPC recommends you install loft and/or cavity wall insulation, you'll need to do so before applying to the RHI scheme. Find out about home insulation grants.
- You need to make your RHI application within 12 months of your first renewable heating system being switched on. You'll find this 'commissioning date' on your MCS certificate).
- If you have a biomass system, you'll need an RHI Emission Certificate for your biomass system (check the RHI ECLIST for eligible products).
Once you've been accepted onto the RHI scheme, there are ongoing obligations you need to meet to get your full RHI payments.
For example, you'll need to keep your heating system in good working order; declare any time your heating system breaks down; and use certified fuel with a biomass system.
