Frances Tait: Combustible cladding ban on high risk buildings in Scotland: What businesses need to know
Frances Tait, who works in the construction and engineering team at Womble Bond Dickinson, outlines the combustible cladding legislation changes set to be introduced in Scotland.
Everyone’s full attention has been on the Building Safety Bill (now the Building Safety Act 2022) receiving Royal Assent on 28 April 2022 – but it is important to remember that, north of the border, the building safety regime is quite different.
In fact, Scotland has recently seen its own important development in building and fire safety, quite separately to the Building Safety Act (which only applies in England and Wales).
It is vital for construction industry professionals (such as developers and designers) and contractors, to understand these legislative differences. Law firm Womble Bond Dickinson (WBD) has shared what the changes will entail for businesses building in Scotland.
The changes explained
On 22 April 2022, the Building (Scotland) Amendment Regulations 2022 were laid before Scottish Parliament. These new Regulations provide for strict rules in relation to cladding for buildings, beyond those set out in the legislation for England and Wales.
The Building (Scotland) Amendment Regulations 2022 ban the use of combustible materials on the outside of all new build residential and other “high risk” buildings taller than 11 metres. The changes also apply to re-cladding works to the same classification of buildings. (In contrast, the position in England and Wales is that a ban on combustible cladding only applies to residential buildings taller than 18 metres.)
Cladding systems on high rise blocks of flats in Scotland have either had to use non-combustible materials or pass a large-scale fire test since 2005 - however the new Regulations remove the option of a fire test, completely prohibiting combustible materials from use on domestic and other high-risk buildings, such as care homes and hospitals, above 11 metres.
The new Regulations also provide for a complete ban on cladding made from metal composite materials on any new building of any height. This will cover the highest risk metal composite cladding materials, such as high-pressure laminates (HPL) and the aluminium composite materials (ACM) used on Grenfell Tower.
When do these changes come into effect?
The new Regulations will be introduced on 1 June 2022 and will apply to new builds and the re-cladding of existing buildings.
