Degression for the RHI Tariff for domestic biomass

Domestic Renewable Heat Incentive applications are monitored closely. When targets are exceeded this triggers a degression or reduction in the tariff.

Applications for domestic biomass installations for the domestic Renewable Heat Incentive have exceeded targets and from the 1 April 2015 there will be a 20% degression from 10.98 to 8.93p.

This degression will affect all new installations where the installation has not been completed and claimed for.

If you are in any doubt about your application you should have:

1 – A Green Deal Assessment

2 – An MCS certificate that covers the installation of an MCS accredited boiler by an MCS accredited company

For legacy applications before 9 April 2014 the tariff is still at 12.2p for biomass installations. You must, however, apply before 8 April. For instance you may have been waiting to take action on your insulation.

Rates for other technologies such as heat pumps and solar thermal have remained unaffected – and even risen slightly as they have been adjusted for inflation.

These are now:

Applications submitted Biomass boilers and stoves Air source heat pumps Ground source heat pumps Solar thermal
