HC Deb 21 November 1983 vol 49 c33W
Sir Hector Monro

asked the Secretary of State for the Environment what is the target temperature, in degrees, to which rooms are heated in the House; and how much expenditure could be saved by reducing the temperature by 5 deg Fahrenheit.

Sir George Young

The various heating systems in the Palace of Westminster are such that individual room temperatures cannot currently be controlled precisely. A modernisation programme was started in 1978 but it will take a further two to three years to complete. However, in the meantime temperatures are monitored in key public areas four times a day [at 2 pm Tuesday 15 November, temperatures varied between 66°F in the Cloisters and 73°F in the Central Lobby].

It is not possible, without undue time and cost, to calculate accurately the likely saving if temperatures were to be reduce by 5°F, but a reduction of this magnitude could give rise to savings of around £30,000/£35,000 per annum.
