HC Deb 15 December 1983 vol 50 c543W
Mr. Norman Atkinson

asked the Prime Minister if she will recommend the installation throughout all working areas of 10 Downing street of those new forms of British electric lighting that reduce energy consumption whilst improving light output.

The Prime Minister

The Property Services Agency, which is responsible for maintenance of the Government estate, including 10 Downing Street, installs high efficiency light sources as its normal practice, wherever these would be cost-effective. Lamps must, however, be suitable for the intended purpose.
