Energy saving advice

​​Improve your home

There are lots of ways to make your home more energy efficient, and when you save energy you save money. Below are just a few suggestions that could help you on your way to reducing your energy bills.

Improving your home's insulation will make you feel warmer during winter and cooler in the summer. This may even mean you're able to turn down your heating, which will save you money on your fuel bills.

Loft insulation

  • a quarter of your home's heat is lost through the roof
  • loft insulation can save you up to £210 per year on your energy bills
  • it is effective for approximately 40 years and will pay for itself over and over again

The recommended depth of loft insulation is 270mm or 11 inches. If you have less than the recommended depth then topping up or laying new insulation will trap the heat in your home more efficiently.

Cavity wall insulation

Wall insulation acts as a giant tea-cosy around your home. If your home was built between 1940 and 1980 it is worth checking to see if you have cavity walls, and whether they are empty.

  • around a third of all heat lost in an uninsulated house is lost through its external walls
  • you could save around £200 per year on your heating bills

Cavity wall insulation is blown into the cavity from the outside through small holes drilled into the walls.  This work should be carried out by a registered installer.

Heating systems

Heating your home and hot water accounts for around 60% of your yearly energy bills. Having an efficient heating system can make a big difference.  

  • if you have an oil or gas boiler which is over 10 years old, replacing it with a new A-rated condensing boiler could save you up to £470 per year
  • if you have electric heating which is over 10 years old, we recommend investigating if modern units could save you money
  • putting an insulation jacket on your hot water tank could save you up to £150 per year

If you do look to replace your existing boiler, it's worth asking your installer to check if it is the correct size for your property - remember a smaller boiler will cost you less to buy and to run.

Make sure your heating is coming on when you want it to and for the right length of time. Having better control over when you're heating your home could help save money on your fuel bills.
