# Fibre Cement Building Boards: Trade Body Accreditation

Fibre cement building boards fall under the oversight of several key UK regulatory frameworks and trade bodies. The British Standards Institution (BSI) sets the standards that products must meet, particularly BS EN 12467, which specifies the performance requirements and test methods for fibre cement flat sheets. The Construction Products Regulation (CPR) requires manufacturers to provide CE marking and technical documentation proving compliance with European harmonised standards. Additionally, many accredited suppliers are members of the Insulated Metallic Building Products Association or adhere to standards set by the UK's Health and Safety Executive regarding asbestos-free manufacturing. These certifications collectively ensure that products are safe, durable, and suitable for their intended applications in construction.

Verifying a provider's accreditation is straightforward and essential before making a purchase. You can check whether a supplier is BSI-certified by consulting the BSI's online register of accredited businesses, and you should ask for copies of their CE marking certificates and technical datasheets that confirm compliance with relevant standards. Legitimate suppliers will readily provide third-party test reports demonstrating their products meet fire safety, moisture resistance, and durability specifications. It matters because accredited providers are subject to regular audits and quality controls, meaning you have genuine recourse if products fail to perform as specified. Working with non-accredited suppliers carries significant risk: products may not perform as advertised, your building warranty could be invalidated, and you may face liability issues if defects cause problems later.

Accredited fibre cement board suppliers typically charge 10 to 25 per cent more than unaccredited alternatives, reflecting the costs of maintaining certification, insurance, and rigorous quality testing. However, this premium is normally worthwhile because accreditation substantially reduces risk of costly failures, protects your building's longevity, and
