MHCLG’s Plan acknowledged that uncertainty around how many 11–18 metre buildings needed to be remediated meant that many residents were unsure about the safety of their homes and the timeline for getting them fixed.15 When asked what it was doing to identify remaining unsafe buildings, MHCLG said Homes England was investigating unique building records. Homes England explained that, in autumn 2024, it had started investigating around 220,000 unique records of four storey buildings to create a register of buildings over 11 metres. We heard that it would shortly start reviewing around half a million further unique records for three–storey buildings. Homes England told us that it was checking the height of these buildings, and their cladding materials using tools such as Google Earth, and that it was reviewing Land Registry data and leases to obtain ownership details. Homes England said it intended to complete its investigations by December 2025. Registration of all high–rise residential buildings was made mandatory under the Building Safety Act 2022, but MHCLG told us that mandatory registration for 11-18 metre buildings, as promised in its Plan, was contingent on legislation, for which timescales were uncertain.16
