Dr Allan has raised an extremely important point. I referred to consumer protection in relation to district heating, but given the wider investment that the Government is making, we agree that it is imperative that we protect householders when they have work done to improve their homes and make them more energy efficient.

Through Scottish Government run energy-efficiency schemes, we are putting in place provisions to protect consumers—for example, the warmer homes Scotland contract requires that installations be completed to a high standard, and all measures are inspected to ensure that they are completed to a high standard. We wish that such conditions applied to other schemes across the UK.

For local authority area-based schemes, all authorities are required to provide a quality-assurance service, including access to a formal complaints process, on-site monitoring of the quality of the works and post-completion advice. We are learning lessons from previous schemes and have established a short-life working group on quality assurance, consumer protection, skills and the supply chain, which will report its recommendations shortly.
