# Metal Door Installation Trade Body Accreditation

The main UK trade bodies relevant to metal door installation include FENSA, which certifies installers of windows, doors and conservatories and ensures work meets Building Regulations, and the National Association of Master Locksmiths (NAML), which covers security door installation and access control. For more specialised metal security doors, the Security Door and Hardware Association (SDHA) provides relevant accreditation, whilst installers working on listed buildings or heritage properties may need Conservation Accreditation Register for England (CARE) certification. The British Standards Institution (BSI) also sets technical standards that reputable installers follow, and some providers hold Kitemark certification to demonstrate compliance with BS standards for doors and frames. These accreditations collectively signal that an installer has met safety standards, carries appropriate insurance, follows professional codes of conduct, and keeps up with training and industry best practice.

To verify a provider's credentials, ask for their accreditation certificate details and check them directly on the relevant trade body's online register before booking. FENSA-registered installers can be verified through the FENSA website's "Find an Installer" tool, while NAML members are listed on the NAML directory. Request evidence of public liability insurance, which accredited bodies require, and check whether they hold any additional certifications such as Gas Safe or Secured by Design accreditation if relevant to your installation. This verification matters because it protects you legally: work done by FENSA-certified installers on compliant doors will be signed off with a Building Regulations certificate, which is essential for insurance claims and when selling your property. It also means the installer is bound by a disputes resolution scheme if something goes wrong, giving you recourse beyond pursuing the company directly.

Accredited metal door installers typically charge between 10 and 25 per cent more
