The Welsh Government has launched a consultation on proposed regulations under the Building Safety (Wales) Act 2026 concerning determinations of the principal accountable person (PAP), registration of category 1 and 2 buildings with building safety authorities and related fees. The proposals would provide a process for accountable persons to apply jointly to the building safety authority for a determination as to which of them is the PAP where more than one person may meet the relevant statutory criteria, with the authority able to decline to determine the matter where it considers that the issue is better suited to the Residential Property Tribunal. The consultation also sets out proposed registration requirements for category 1 and 2 buildings, including information on building height, storeys, residential units and accountable persons. For category 1 buildings constructed after July 2026 which have gone through the new Gateway 3 process, the proposals would also require confirmation that a partial or full completion certificate is in place. The Welsh Government proposes that specified information from the register, including the building address, category, height, number of storeys and name of the PAP, should be publicly available. It also proposes a £100 fee for PAP determinations by the building safety authority and a £250 fee for applications to register category 1 or 2 buildings. The consultation closes on 18 December 2026.
