Since the IPA’s remit covers the government major programmes portfolio, it does not extend to the restoration and renewal of the Houses of Parliament, or the associated Northern Estates programme.54 The Restoration and Renewal programme is overseen by a Sponsor body and a Delivery authority, both of which are ultimately accountable to Parliament, and the IPA were not given a role in The Parliamentary Buildings (Restoration and Renewal) Act 2019 (the Act) which set out how the Programme would be managed. The programme is highly complex with a number of uncertainties that underpin it, including the condition of the building, its interdependencies with other Parliamentary building projects, and the lack of consensus over the scope of the programme, and how to relocate staff as the programme is underway.55
