Properly used, dishwashers use less water and energy than washing dishes by hand. However, make sure you only wash full loads and don’t pre-rinse everything in the sink first unless it really needs it.

Cavity wall insulation can help prevent heat loss through your walls. Consider getting this retro-fitted if you still have uninsulated walls.

Insulation prevents heat moving in and out of a building. This makes it even more important for buildings with cooling systems which can benefit in both hot and cold weather.

Thermostatic radiator valves (TRVs) help ensure your heating is evenly distributed where you need it. Check them to make sure they are set properly so each area reaches the temperature you need and gets no hotter.

Electric storage hot water units use energy all the time they are switched on. Consider fitting them with time switches so they are only working when they are needed.

Litter belongs in bins! Stuffing litter behind radiators not only prevents them working efficiently but can also be a fire risk.

Make sure you get your boiler properly serviced every year by a competent person. It will keep you warm, safe and make sure it is working efficiently.
