The Green Construction Board commissioned Peter Hansford, Chief Construction Adviser to the Government, to undertake a review of solid wall insulation. The review was to consider what more might be done to unlock demand for SWI, improve its affordability and increase its attractiveness as a solution. A call for evidence was made in April. Green Construction Board members, Rob Lambe (Willmott Dixon) and Lynne Sullivan (SustainableByDesign) agreed to support Peter as a Steering Group to the commission. The review team worked closely with but remained independent from DECC and DCLG. The Solid Wall Insulation report was published on 12 November 2015.
