To ask the right hon. Member for Carshalton and Wallington, representing the House of Commons Commission, what estimate it has made of the cost of a change in the timetable for a decision on the proposed restoration and renewal programme for the Palace of Westminster.
18 July 2017
The Joint Committee on the Palace of Westminster, published its report on the Restoration and Renewal (R&R) of the Palace of Westminster in September 2016.
The report set out next steps for the Programme, based on the Joint Committee’s recommendation that a full decant be undertaken to deliver the works, stressing that timings were indicative only and that it will be for the proposed Delivery Authority, once established, to put together a more detailed schedule for the development of the Programme.
The Independent Options Appraisal produced by the Deloitte-led consortium and published in June 2015 provided estimates of the inflationary impact on capital expenditure of a delay to the construction start date. A range of estimates were provided across the options under consideration and at different levels of certainty. Based on the scenario of full decant, as recommended by the Joint Committee, with some defined improvements to the Palace, the range of predicted inflationary impacts was £78m to £167m per annum.
Additional costs for ongoing maintenance to the Palace will also continue to be incurred.
