New regulations have come into force today which change the way that Domestic RHI payments are now calculated.
A cap has been introduced which limits the eligible kWh that can be claimed against RHI payments. These are:
Ground Source Heat Pump: 30,000kWh
Air Source Heat Pump: 20,000kWh
Biomass Boiler: 30,000kWh
Domestic RHI payments are based on the kWh figure stated on an Energy Performance Certificate. Whereas previously claimants had no limit to their applications, the above figures now caps the EPC figure. In reality we don’t expect this to impact on the majority of homes, particularly new-build dwellings, where the low heat loss characteristics of the property mean the number of kWh on the EPC should be lower than the figures above.
This only affects on new installations, and does not change installations registered prior to 20th September 2017.
