Recommended cut in winter heating guidance

Simple steps to save energy and money.

New guidance from Public Health England on recommended heating levels in the home which could lead to lower energy bills is being supported by Swale Heating, the South East’s largest independent heating company.

Last winter, Public Health England said rooms occupied during the day should be kept at a minimum of 21C, and 18C at night. But now it has altered its view to a new recommendation of at least 18C day or night.

Kent-based Swale Heating agrees with the new advice, pointing out that a reduction of just one degree could cut the typical gas bill by as much as £55 a year.

The company’s sales director Matthew Edwards says: “Public Health England found that the previous guidelines were based on outdated World Health Organisation figures from 30 years ago. A new review has resulted in the lower recommendation of at least 18C, which it says poses minimal risk to the health of a sedentary person, wearing suitable clothing in winter.”

The new guidance says that below that level, the danger of stroke or heart attack begins to increase. However, the government body adds that those aged over 65 and those with medical conditions may benefit from a slightly higher temperature.

Matthew says: “We all want to cut the rising costs of keeping our homes warm so following advice like this makes sense. Everyone can take a few simple steps right away and save energy as well as money.

“If you have a programmer, set it so that the heating only comes on when needed. Switching off your boiler when no one’s home saves money. You can reduce the energy your boiler consumes by up to 40% with efficient room thermostats and thermostatic radiator valves while replacing a 10-year-old boiler with an efficient A-rated new one could reduce your energy consumption by a third.”
