§ Mr. Peter Bruinvelsasked the Secretary of State for the Environment if he will update the figures given in reply to the hon. Member for Cheltenham (Mr. Irving), Official Report, 25 April 1984, column 526, regarding the total 638W additional cost to his Department of the House sitting from (a) 10.30 pm to midnight and (b) from midnight to 2 am; and if he will give similar estimates for such periods after 2 am as figures are conveniently available.
§ Sir George Young[pursuant to his reply, 21 March 1985]: The figures for additional labour costs to my Department given in my answer of 25 April 1984 remain valid. After 2 am additional labour costs amount to £30 per hour until the normal day staff come on duty. The additional heating and lighting costs are now estimated to be about £345 for the period between 11 pm and midnight, and £135 per hour after midnight.
