| While it might be tempting to avoid using the heating to save money, the government recommends a room temperature of at least 18C. Older people and those who are ill or disabled may need it to be warmer. | While it might be tempting to avoid using the heating to save money, the government recommends a room temperature of at least 18C.

| How this saving is worked out: Experts at Cambridge Architectural Research (CAR) found that turning the thermostat down from 19C to 18C would save 13% on an average annual gas bill - that's about £157 now. It suggests 68% of homes could benefit. Its findings are based on estimated energy use in 12,300 homes surveyed by the English Housing Survey. CAR was asked to carry out the study by the government in 2012. The Energy Saving Trust estimates a saving of £145 a year, if temperatures are reduced from 22C to 21C in main living areas. | How this saving is worked out: Experts at Cambridge Architectural Research (CAR) found that turning the thermostat down from 19C to 18C would save 13% on an average annual gas bill - that's about £157 now.

It's important not to set it any lower as it could create a health risk - legionella bacteria could develop in the water. | If you have a conventional boiler (ie a system with a hot water tank), you could try setting it to 65C.

| How this saving is worked out: CAR modelled the saving for reducing the temperature of combi boilers from 75C to 60C. It found this would save 8% on an average annual gas bill - about £97. It suggests 38% of homes in the UK could save money with this measure. The study was carried out in 2022. | How this saving is worked out: CAR modelled the saving for reducing the temperature of combi boilers from 75C to 60C.

| They work by restricting the amount of water coming through the head. This means you use less hot water for the same length of shower. This could mean a saving of about £98 a year if you don't have shorter showers. | They work by restricting the amount of water coming through the head.

| How this saving is worked out: CAR assumes that each household takes two showers a day, that an average shower lasts seven minutes, uses eight litres a minute and has a temperature of 41C. It says four-minute showers would save an average of 24 litres of hot water, resulting in an energy saving of 1.1 kWh per shower, or around 800 kWh per year for a household. CAR also estimated that a low-flow shower head would save an average of 28 litres of hot water, resulting an energy saving of 1.3 kWh per shower, or around 950 kWh per year for a household. | How this saving is worked out: CAR assumes that each household takes two showers a day, that an average shower lasts seven minutes, uses eight litres a minute and has a temperature of 41C.

| How is the saving worked out: CAR's study found that homes with radiator valves are likely to have partially adjusted them so that rooms outside the main living area are already 1.5°C cooler. However, reducing the temperature by a further 1.5°C could save 5.5% of the total gas bill (a saving of £68). Its modelling found that 76% of UK homes could save with this measure. | How is the saving worked out: CAR's study found that homes with radiator valves are likely to have partially adjusted them so that rooms outside the main living area are already 1.5°C cooler.

| Combining all measures could potentially save a typical household £530 per year, according to Nesta/CAR/Energy Saving Trust calculations. Due to the potential for double counting, this is less than the £625 total of adding up each individual measure in this article. There are dangers in overly severe energy rationing - underheated and damp homes come with health risks. | Combining all measures could potentially save a typical household £530 per year, according to Nesta/CAR/Energy Saving Trust calculations.
