Metering for payment only applies for biomass plants and heat pumps. Solar thermal for heating domestic hot water never has to be metered for payment.
Most people will have their Domestic RHI payments based on estimated heat demand, using details found on their Energy Performance Certificate (EPC) open key term pop-up. In certain situations we can’t easily or accurately estimate this and, in these cases, people are instead required to install meters and submit readings every three months. We need this information so that we can work out how much to pay you.
There are various situations where you will need to install meters for payment - the three most common ones are:
- Where you have a back-up heating technology, such as a gas or oil boiler.
- Where you have a biomass heating system that isn’t both designed and installed to heat the whole property.
- Where your property is occupied for less than 183 days in the 12 months prior to applying to the Domestic RHI, and any time whilst you’re a member of the Domestic RHI scheme (unless your property is a Custom-buildsopen key term pop-up)
- If your circumstances change during their participation in the scheme, metering may become a condition for them to carry on receiving payments, even though payments were on an estimated heat demand basis to begin with.
