Free Cavity Wall Insulation for Council Tenants may be available if your home has cavity walls but no cavity wall insulation.
Most homes built between 1926 and the end of 1982 will be affected because Building Regulations did not require cavity wall insulation to be installed then. Before 1926 most homes in the UK were built with solid walls so cannot have cavity wall insulation installed.
