Energy saving advice

The Energy Saving Trust provides free and impartial advice to help you be more energy efficient.

By being efficient you can:

  • use less energy
  • save money
  • still keep your home warm
  • produce less carbon dioxide, which helps slow down climate change

Keep your boiler efficient

Looking after your central heating and hot water boiler is an important way to save energy.

As general rules:

  • boilers over 10 years are normally only 50% to 65% efficient
  • wall mounted boilers are more efficient than floor mounted boilers
  • boilers that get checked regularly are more efficient
  • new boilers are the most efficient, up to 95%

You can find out how boiler efficiency is calculated and if a new boiler could save you money on the Which? website.

Smart meters

Smart meters show how much gas and electricity your home is using and how much your energy bill will be each month. They're more accurate and easier to read than older energy meters.

If you don't already have a smart meter, you can ask your energy supplier to upgrade for free.

Efficient home appliances

When you buy a new household appliance, for example a fridge or dishwasher, you should look out for the energy rating label on the appliance.

The label will show the energy rating of the appliance, from A to G.

A is the highest and most energy efficient rating. G is the lowest and least energy efficient rating.

If they're the same size, an A rated appliance will use less than half the energy of a G rated appliance.

You can find more information on energy labels and ratings on the Energy Saving Trust website.
