HC Deb 24 July 1987 vol 120 c523W
Mr. Yeo

asked the Secretary of State for Energy how many schemes have been implemented to replace overhead electricity and telephone cables with underground cables in conservation areas and areas of outstanding natural beauty.

Mr. Michael Spicer

This information is not readily available in respect of electricity cables and could be obtained only at disproportionate cost. Telephone cables are a matter for my right hon. and learned Friend the Chancellor of the Duchy of Lancaster.
