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

To ask the Secretary of State for Business, Energy and Industrial Strategy, how many businesses have had boilers installed under the non-domestic Renewable Heat Incentive scheme; and how many of those boilers will be inspected as part of the National Audit Office's study into that scheme.

The Non-domestic Renewable Heat Incentive (RHI) scheme offers support for a range of renewable heat technologies. As of end July 2017, there were 18,904 full applications to the Non-domestic RHI.

The National Audit Office operates independently of the Department. As such, we are not able to comment on their fieldwork plans.
