Making one simple change to your boiler settings could save you £112 a year.
Money-saving charities Nesta and Which? have launched a campaign with energy firms EDF, E.ON Next and Octopus to make a dent in soaring bills this winter. And people are being urged to make a small change which could help millions of households with their energy costs.
People with combi gas boilers should have it set to a "flow temperature" of 60C or below, to use the gas in the most efficient way possible, Nesta explained. However, many boilers run hotter than that - which uses more gas as heat is lost from the pipes in your home.
