Barry Sheerman – 2016 Parliamentary Question to the Department for Energy and Climate Change

The below Parliamentary question was asked by Barry Sheerman on 2016-04-19.

To ask the Secretary of State for Energy and Climate Change, what recent representations she has received on the potential link between cavity wall insulation and dampness in houses.

Andrea Leadsom

Under the Energy Company Obligation, which is the primary government support for measures of this type, the insulation of a cavity wall must be accompanied by an appropriate guarantee, approved by Ofgem. Amongst other criteria, the guarantee must include an assurance framework for the quality of the installation and the product used in the installation. As the administrator of ECO, Ofgem assess the suitability of this framework.

Alongside this, the Department for Communities and Local Government has begun research into dampness in buildings caused by both internal moisture and wind-driven rain and related to insulation. This project is due for completion later this year. We are also aware of the recent publication of BBA Technical report No. 3, Full fill cavity wall insulation in areas of very severe exposure to wind driven rain.

The results of both projects, together with any other relevant information, will be considered as part of any review of the regulations and associated statutory guidance. DECC and DCLG have also commissioned Dr Peter Bonfield to conduct a wider independent review of consumer advice, quality and standards and consumer protection for energy efficiency and renewable installations. The findings of this review will cover installations of Cavity Wall insulations. This report will be published in due course.
