How to become more energy efficient

How to become more energy efficient

Ways to cut down on the amount of energy used in your home or business and save money whilst keeping warm.

Reduce your energy bills

If you are struggling to pay your energy bills you should contact your energy supplier as there may be support available.

There is extra help available if you are in fuel poverty.

You could also shop around for a better deal or tariff by using a comparison website, which should also have guidance on finding the best deal for you.

Making sure you manage the amount of electricity you use in your home will help reduce your energy bills. For instance:

  • Use an energy meter so that you know how much energy the various appliances in your home use
  • Turn appliances and plugs off when not in use
  • Turn lights off when not in use
  • Use energy efficient light bulbs
  • Consider installing renewable energy

Heating your home and water

By answering questions on your property through the Energy Saving Trust’s Home Energy Check online you could save up to £250 per year. For more general tips, including information on controls and thermostats, visit the heating and hot water pages.

Insulating your home

Good insulation means you stop heat from escaping from your home and prevent cold draughts from entering. The main types of insulation in the home include:

  • Cavity wall
  • Solid wall (external or internal)
  • Loft / roof or room in loft
  • Floor
  • Glazing for windows
  • Draught-proofing
  • Tanks, pipes and radiators

If you are planning to have energy efficiency improvements, you should aim to use an installer who is from one of the following to ensure quality and reliability:

You will not generally need planning permission for carrying out insulation on your walls; however there are important exceptions and it is best to check before carrying out any work.

Home assessments

Whether you’re looking for a new home to rent or buy or new offices for your business, the property you choose must have an Energy Performance Certificate (EPC). These are similar to the multi-coloured stickers on new appliances, which tell you how energy efficient a building is and rate it from A (very efficient) to G (very inefficient). This will give you an idea of how costly it will be to heat and light, and what its carbon dioxide emissions are likely to be, as well as suggestions for improvements that could make the rating higher.

Buying Green Electricity

Most energy suppliers offer 'green' electricity tariffs that support renewable energy. Find a tariff suitable for you via the Green Energy Supply Certification Scheme.
