A guide to help Hertfordshire households save energy has been launched by the county council.
The online document, named Retrofit Resource, also provides information on how to help save water.
It also features advice on how to adapt a home to deal with extreme temperatures.
The guide was written by the Hertfordshire Buildings for Future Partnership, which is comprised of Hertfordshire County Council and the ten district borough authorities.
