Energy Saving Tips

Natural gas is an efficient way to heat your home and provide hot water, but you may be using more energy than you need. Check out our energy saving tips.

Natural gas is an efficient way to heat your home and provide hot water, but being at home more often might mean you are using more energy. Below are some energy saving tips. You may also wish to read our Code of Practice on the Efficient Use of Energy1


Keep your room thermostat (usually in hallway) to a temperature that you feel comfortable with (normally 21oc ). Homes could save up to £80 per year by turning their thermostat down by 1oc2

Set your thermostatic radiator valves in each room to a temperature that suits your circumstances (not always to be set at maximum)


Check that your heating timer is set at the correct times / days that you require heat

Warm House Icon

Set the central heating and domestic hot water output temperatures of the boiler to your desired heat level. This may be lower than what it is currently

Shower Icon

Reduce time in the shower

Natural Gas Boiler Icon

Ensure your gas boiler is serviced each year to ensure boiler efficiency

Advanced Heating Controls

Consider getting advanced controls fitted which allow you to keep in control of your heating whilst out and about or from the comfort of your home.
