Facade specification in the UK looks fundamentally different to how it did before 2017. What was once a decision largely driven by cost and appearance is now shaped by strict fire classifications, formal certification and layers of documentation that didn’t exist a decade ago. Here are six of the clearest ways that shift is playing out.
1. Combustible Materials Are Now Banned Outright on High-Rise Walls
The starting point for almost every change since 2017 is a single regulatory shift. Regulation 7(2) of the Building Regulations now prohibits the use of combustible materials in the external walls of buildings over 18 metres containing dwellings, institutions or residential accommodation, extending to hospitals, care homes and student residences regardless of height. The government’s own announcement on strengthening building product regulation confirms this remains a live area of reform, with further tightening of product safety checks still being rolled out.
2. Non-Combustible Mineral Wool Has Become the Default, Not the Exception
Where a mix of insulation types was once considered on a project-by-project basis, mineral wool systems with A1 or A2-s1,d0 fire classifications are now the starting point for most specifiers working above 11 metres. Manufacturers such as Licata supply mineral wool EWI systems designed specifically to meet this classification, reflecting how far the default specification has moved away from combustible alternatives in under a decade.
3. Manufacturer Certification Has Become Essential to Specification
A render or EWI system without proper third-party certification is now far harder to get signed off, particularly on funded retrofit and higher-risk projects. Installers in Bristol, including Total Render Solutions, report that clients increasingly ask about BBA and manufacturer accreditation before a project even starts, something that was rarely raised as a first question before Grenfell.
4. Fire Cladding Remediation Has Become a Specialism of Its Own
An entire strand of the industry has grown up specifically to deal with buildings that need existing cladding replaced or upgraded to meet current standards. Contractors in Scotland, such as Insulated Render Systems (Scotland), now specialise in fire cladding remediation on high and medium-rise blocks, working within the Building Safety Regulator’s Gateway 2 process and EWS1 requirements that didn’t exist before the regulatory overhaul.
5. Approved Installer Networks Are Under Far More Scrutiny
With certification tied so closely to correct installation, being a manufacturer-approved applicator now carries far more weight than it once did. Contractors in Newcastle, including JMJ External Wall Installation, highlight their approved applicator status with several major system manufacturers as a core part of how they win commercial and housing association work, where compliance now matters as much as price.
6. Documentation and Traceability Are Now Central to Compliance
The Building Safety Act’s “golden thread” requirement, demanding accurate, accessible information on a building’s construction from design through occupation, has changed how facade projects are recorded and handed over. Contractors in West Yorkshire, such as Yorkshire Externals, who work with housing associations and local authorities on schemes ranging from single homes to high-rise blocks, report that documentation now forms a much larger part of every project than it did before the regulatory changes came into force.
