Martin Lewis explains whether keeping heating on all day is cheaper

Martin Lewis and MoneySavingExpert say leaving heating on all day consumes more fuel and generally costs more; they and the Energy Saving Trust report that heating only when needed and using a timer is the more efficient approach.

It has been very cold across the UK and many households have had to use their heating during recent freezing weather. Rising energy costs have made choices about when to heat a home more prominent. MoneySavingExpert and Martin Lewis addressed whether it is cheaper to leave heating on all day or to use it only when needed. Their comments reference formal guidance from the Energy Saving Trust. Key points: - MoneySavingExpert and Martin Lewis say leaving the heating on all day consumes more fuel, leads to greater heat loss, and typically results in higher costs. - The Energy Saving Trust is reported as saying the most efficient approach is to heat a home when it is needed rather than maintain constant heating. - Martin Lewis and MoneySavingExpert recommend using a timer so a thermostat turns the heating on and off to maintain the temperature you set. Summary: The reported guidance is that heating only when needed and using timers reduces fuel use and associated costs. Undetermined at this time.
