The legislation in England has classified that balconies become a ‘specified attachment’ to the external wall. Each component of the balcony (and wall) must consist of non-combustible components, defined as those achieving A1 or A2 - s1 d0 rating against the European Standard BS EN13501-1. Certain specific components are exempted from achieving Class A1 or A2, these are to smaller components to a build which include gaskets, membranes, spacers and fixings.Any projects previously given the notice of approval by building control and those started before the 28th February 2019 are exempt, as well as commercial properties including hotels. In Wales the legislation is similar, though buildings started before 13th January 2020 are exempt. In Scotland, legislation regarding the use of non-combustible materials applies to all buildings over 11 m in height. In Northern Ireland there is currently no legislation beyond the Part B regulations, however we have found Building Control and insurance companies are generally following the English legislation as a guideline.
