Copied from Wandsworth Borough website:

“Under Clauses 2 and 5 of the standard form of lease between the Council and its leaseholders, the Council applied regulations relating to the management of a property. As from 1st October 2017, for the safety of our residents and their neighbours, the Council made an addition to these regulations, which reads as follows: ‘To prevent the spread of fire between your Flat and the common parts, the Lessee must ensure that their front door complies with the relevant building regulations at the time the door was fitted or altered. The door should have a working self closing device.'”
