Question to the Department for Business, Energy and Industrial Strategy:

To ask the Secretary of State for Business, Energy and Industrial Strategy, when his Department last made an assessment of the case for revising the levels of grants for (a) solar panels, (b) domestic biomass heating and (c) other household renewable energy.

A review of the Feed in Tariff scheme took place between August 2015 and December 2015. This included a review of support for small-scale solar PV, onshore wind and hydro installations. An additional review, covering anaerobic digestion and micro-combined heat and power installations, concluded in February 2017.

Domestic heating from solar thermal panels, biomass boilers and stoves, and air source and ground source heat pumps, is supported by the Domestic Renewable Heat Incentive (RHI), introduced in April 2014.

In March 2016, the Government set out its initial proposals for reform of the RHI scheme in the consultation: The Renewable Heat Incentive - A reformed and refocused scheme. This included an assessment of the tariff levels available through the scheme.
