RHI Regulations laid before Parliament

RHI Regulations laid before Parliament

31 August 2017

The Government has laid new RHI legislation before Parliament yesterday. The regulations were made on the 29th August, laid before Parliament on the 30th August, and will come into effect on the 20th September 2017.

The regulations are different to the draft regulations laid earlier this year, and only contains some of the changes announced in the RHI reform in December 2016. It is our understanding that the Government has decided to split up the implementation into two, depending on whether they required an affirmative or negative resolution parliamentary procedure.


The changes implemented now are:

  • Alignment of non-domestic biomass tariff (tier 1: 2.96p/kWth, tier 2: 2.08p/kWth) and changes of load factor from 15% to 35%.
  • New degression triggers until July 2018
  • Domestic demand limits for domestic biomass, ASHP, and GSHP
  • New tariffs for domestic RHI 
    • Biomass plants: 6.54p/kWh
    • Air source heat pumps: 10.18p/kWh
    • Ground source heat pumps: 19.86p/kWh
    • Solar thermal plants: 20.06p/kWh
  • Provisions to receive higher tariffs for plants whose tariff start date is on or after 14th December 2016 but before 1st April 2017 to be able to receive the higher tariffs
