When cooking you can often use the residual heat to to save energy if you switch your cooker off just before you finish cooking. However, you still need to make sure that your food is properly cooked through.

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.

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.

Using lids on your pans when cooking will save energy and help heat the contents quicker.

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.

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.

Use a microwave. Generally a microwave oven is the most efficient way to heat up and cook food.

Only fill your kettle with the water you need. You will save both water and energy.
