If you have a traditional central heating system then think carefully about your heating – how warm it needs to be and how it is controlled.
If you have a programmer, then programme the heating to be on only when needed – this might require programming different days of the week individually according to when the home is usually occupied. If you have done a good job with your draught stripping, you might find that you can turn the heating off an hour earlier without getting too cold.
Consider getting a smart thermostat so that you can control your heating remotely using an app on your smartphone.
A quick win is to turn the temperature down on your thermostat and get used to wearing warmer clothing in the house.
If you have thermostatic radiator valves, then turn them down or off in rooms that are not in use. If you don’t have thermostatic radiator valves, consider getting them.

To maximise the efficiency of radiators, try and keep them free from obstructions – do not let curtains hang over them and move furniture away so that the air can circulate.
Turn down the flow temperature on your boiler – this is the temperature that the water gets to for heating and domestic hot water. The recommended settings vary according to the type of boiler and system you have, so find out the detail you need on the Heating Hub website here.
*Not a small thing: If your boiler is old and inefficient, the standard advice is to replace it with a newer and more efficient model. While this will reduce gas consumption and may be the best answer for many people in the short term, we would encourage you to investigate low carbon alternatives such as heat pumps. The typical service life of a gas boiler is 15 years, so by installing a new one, you are effectively locking yourself into those carbon emissions for years to come. Again, this is a large investment and requires thought and you should take advice from an expert before making a decision. In most cases a heat pump will not simply replace a boiler, other alterations to the heating system may be necessary.
