asked the Secretary of State for the Environment if he will take steps to have the Clorius heat measurement meters used on many local authority housing estates investigated and tested for accuracy by the National Physical Laboratory or other approved testing institution.

The Clorius meter was exhaustively tested under laboratory conditions in Denmark in 1952 and, on present information, I do not consider that further laboratory tests would be helpful.However, I am satisfied that testing of the meters in use could be of value. Such tests in dwellings were started by the Building Research Establishment in 1977 and a further series will shortly be commenced. It is too early to say when conclusive results will be available.
