Insulating homes saves money and lives.

Homes that are badly insulated and poorly heated make people ill, contribute to climate change and cost a fortune to heat.

Over 4 million households now live in fuel poverty (when you can't afford to heat your home to a reasonable standard). This includes the old, the poor, students and the disabled.

A passive solar corridor and good insulation helps keep the temperature constant in this earth sheltered berm house so it requires no heating system. Photo: Lyndsay Maiden, Cardiff Friends of the Earth
