# Security Door Manufacturing Accreditation

In the UK, security door manufacturers should ideally hold accreditation from recognised trade bodies such as the Security Systems and Alarms Inspection Board (SSAIB), the Master Locksmiths Association (MLA), or compliance with BSI standards, particularly BS 7950 which covers the specification and installation of security glazing. Many reputable manufacturers also seek certification from the British Standards Institution (BSI) for their manufacturing processes and quality control. Additionally, some may hold Police Secured by Design (SBD) accreditation, which indicates that products have been assessed by police crime prevention specialists and meet stringent security standards. These certifications demonstrate that a manufacturer follows recognised safety protocols, uses appropriate materials, and has undergone independent verification of their processes and finished products.

To verify a provider's credentials, you should ask for documentary evidence of their accreditations and check directly with the relevant trade bodies' online registers where applicable. The SSAIB, MLA, and BSI all maintain searchable databases of accredited members, so you can independently confirm whether a company's claims are genuine. It is important to do this verification because fraudulent claims of accreditation are not uncommon in the security sector, and genuine accreditation means the manufacturer has submitted to regular audits, quality checks, and independent inspection. You should also ask for references from recent clients and verify that insurance companies recognise their accreditation, as many will offer better terms or faster claims settlement for doors fitted by certified installers.

Accredited security door manufacturers typically charge 15 to 30 per cent more than non-accredited competitors, reflecting the cost of maintaining certification, undergoing regular audits, and using verified materials and processes. While this premium may seem significant, it often proves worthwhile because accredited doors are more likely to meet their stated security ratings, perform reliably
