From: Public Accounts Committee

Inquiry: Restoration and Renewal of Parliament: Costing and governance

Summary

Joint letter from the Clerks of both Houses to the Public Accounts Committee on the Restoration and Renewal (R&R) Programme, dated 13 July 2026. The Clerks confirm acceptance of the NAO's recommendations and emphasise the critical need for parliamentary approval of the R&R Client Board's costed proposals to progress the £3 billion phase one works. They highlight accumulating costs from parliamentary debate delays (£100m–£479m depending on timing), interdependencies with other estate projects, and ongoing Member engagement despite mixed views on delivery options.

Key findings

  • Parliamentary debate delays since the expected Easter 2026 timing cost £100–135m if held in July 2026, rising to £223–288m if delayed to December 2026, and over £479m if held in early/mid-2027, due to inflation, maintenance, and unnecessary option development.
  • The R&R Client Board recommends reducing four delivery options to two ('full decant' and 'enhanced maintenance and improvement plus') and seeks approval for a seven-year, £3 billion capped phase one works package with a final delivery option decision by 2030.
  • Ministry of Defence unavailability of car park land has extended the Commons Building and Infrastructure Portfolio (CBIP) timeline by four years and increased Richmond House costs by circa £258m, with potential R&R Programme impacts of £280–600m excluding inflation.
  • Over 850 direct engagement interactions with Members in the new Parliament alone (44% of sitting MPs, 35% of Lords members engaged); Members express frustration at delays, health and safety concerns, and mixed views on decant versus enhanced maintenance options.
  • Clerks accept NAO's conclusion that the Client Board's costed proposals provide sufficient information for decision-making and that phase one works are sensible; financial controls include monthly HMT/Cabinet Office meetings, annual estimates scrutiny with public hearings, and NAO audit of Delivery Authority accounts.
