This report arises out of the Working Group set up by The Watt Committee on Energy to examine the issues relating to domestic use and affordable warmth, including hard-to-heat houses, low income and fuel poverty. The Working Group has reviewed the evidence of studies undertaken over the past two decades by government departments, local authorities, voluntary organizations and other agencies. It has subsequently established a clear methodology for considering policy options and proposes a range of solutions. Domestic Energy and Affordable Warmth , with contributions from both academia and industry, and also calling on the expertise of others deeply involved in the subject, provides the reader with an authoritative coverage, defining the difficulties and identifying strategies for dealing with problems in providing affordable warmth to those living on low means or in inadequate premises.
