The Building (Amendment) Regulations SI 2018/1230

The Government has laid the regulations (the Building (Amendment) Regulations SI 2018/1230) before Parliament implementing the ban on the use of combustible materials in the external walls of certain high rise buildings. New regulation 7(2) of the Building Regulations 2010 applies to any building with a storey at least 18m above ground level and which contains:

  • one or more dwellings
  • an institution
  • a room for residential purposes (excluding any room in a hostel, hotel or a boarding house)

This includes residential blocks of flats, student accommodations, care homes, sheltered housing, hospitals and dormitories in boarding schools with a storey above 18 m in height. Regulation 7(2) requires that all materials which become part of an external wall or specified attachment achieve European Class A2-s1, d0 or Class A1 except for components exempted in Regulation 7(3).

The Government has also issued amendments to Approved Document B to support this new regulation and a paragraph in AD7 referring the reader to ADB. The regulations come into force on 21 December 2018 and there is a two month transition period. A circular letter setting out the changes, transitional provisions and so on will be published shortly.
