Question to the Ministry of Housing, Communities and Local Government:

To ask the Secretary of State for Housing, Communities and Local Government, if she will publish the full tranching model from the Building Safety Regulator setting out the approach to be taken for calling in applications for building assessment certificates for existing higher-risk buildings.

The Building Safety Regulator (BSR) advised the Department on 26 March 2025 that:

(a) 1454 directions have been issued

(b) 1368 BAC applications have been submitted

(c) 12 Building Assessment Certificates have been issued

(d) 1 application has been refused

The BSR have also set out that in year 1, the first tranche of buildings have been directed based on meeting at least one of the following criteria:

• over 30 metres to 49.99 metres high with more than 217 residential units
• over 50 metres high with more than 11 residential units
• clad with combustible aluminium composite material
• buildings of large panel system construction built between 1956 and 1973 with a gas supply, where it was unclear if reinforcement work has been carried out.

Plans for future tranches are still being determined.
