§ Mr. Spellerasked the Secretary of State for the Environment if he will take steps to prevent the rateable value of houses being increased when active or passive solar heating is installed.
§ Mr. WaldegraveSection 21 of the Local Government Act 1974 already provides that central heating systems installed after 1 April 1974, and any minor improvements carried out from that date which would have had the effect of raising the gross value by £30 or less, will not normally result in an increase in the rateable value of a dwelling until the next revaluation. A solar heating system providing for or assisting with the heating of two or more rooms in a house would be covered by this provision.
