HC Deb 23 February 1973 vol 851 c226W
Mr. Crouch

asked the Secretary of State for the Environment why houses with electric night storage central heating are rated lower than identical houses with other systems of central heating.

Mr. Eldon Griffiths

Rateable values are based solely on rental values. These are not affected by appliances like night storage heaters which the tenant can take away with him. Other systems of central heating form part of the structure of the property and thus increase the rental value.
