Draught excluders are a cheap way of cutting out the chill from poorly fitting doors and windows. Most are also easy to fit, a simple DIY task.

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.

Keeping the oven door closed while you are cooking helps keep your oven at a stable temperature. It can also improve your cooking whilst saving you energy.

Are your heating costs literally going through the roof? Check to ensure you have 250-270 mm of loose roll loft insulation and top up if necessary.

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

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.

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.

Use the sun to reduce your heating bills. Leave internal doors open to rooms which trap the sun so the heat can spread to other areas.

Building Management Systems (BMS) are great for controlling your building systems efficiently, but only if they have been properly set up! Check your system is properly configured.
