Domestic Renewable Heat Incentive degression

Each year the Department of Energy & Climate Change (DECC) will release a quarterly forecast statement of the Domestic RHI based on Ofgem's 'RHI public report'. Quarterly publications will be made on the following dates (or the nearest working day prior):

1 March

1 June

1 September

1 December

If a degression trigger is hit for a particular technology, there will be a 10% tariff reduction. If a super trigger is hit, then there maybe a 20% reduction. This only concerns new applicants who have not yet joined the scheme.

The new tariff will come into effect on the 1st of the following month.

The report of 1 December 2014 has seen the first trigger for biomass being hit. Therefore, as of 1 January 2015, the Domestic RHI tariff for biomass is being reduced from £0.122 to £0.1098 per kW.
