If you have a timer on your central heating system, set the heating and hot water to come on only when required.
Big Energy Saving Week, which runs from January 18-24, is part of a national campaign to help people cut their fuel bills and get all the financial support they are entitled to.
Energy UK, the trade association for the energy industry, says: “Energy efficiency is essential to help consumers reduce their energy consumption and improve the comfort of their homes.
“It is also central to achieving the UK’s commitment to reducing its greenhouse gas emissions by at least 80 per cent by 2050, relative to 1990 levels.”
