HC Deb 15 February 1982 vol 18 c2W
Mr. Arthur Lewis

asked the Secretary of State for Industry if he will issue a direction to British Telecommunications to install meters on subscribers' telephones that would enable them to check their calls and charges in a similar manner to the manner in which meters are provided for users of gas and electricity.

Mr. Wakeham

No. I understand that it would not be feasible to locate the complex metering equipment required on the subscriber's telephone.
