Almost half of the UK's carbon dioxide emissions come from energy we use every day – much of it at home. By saving energy we can all help prevent climate change.

And by making more efficient use of energy and reducing waste we make our homes more comfortable – and save money on bills.

Grants may also be available to offset against the cost of energy efficiency measures.

Take a trip around the Energy Saving Trust interactive house to check the energy efficiency of your home.
