Question

To ask the Secretary of State for Energy and Climate Change, how many installations of (a) solar thermal, (b) ground source heat pumps, (c) biomass and (d) air source heat pumps took place under the domestic Renewable Heat Incentive in 2014-15; and what forecasts her Department had made of the number of such installations in that period.

The Department publishes monthly statistics for the Renewable Heat Incentive (RHI), which are available at: https://www.gov.uk/government/collections/renewable-heat-incentive-statistics. Table 2.9 has figures relevant to this question.

The following figures are from April 2014 to May 2015, and show the number of installations accredited under the domestic RHI:

a) Solar thermal - 6,372

b) Ground-source heat pumps - 4,684

c) Biomass - 8,547

d) Air-source heat pumps - 15,021

In December 2013, DECC published an assessment of the total installations of renewable heating measures in 2015/16. Deployment was expected to be between 21,350 and 44,930.
