# Security Lighting Installation: Trade Body Accreditation

The main UK trade bodies relevant to security lighting installation include the National Association of Security and Fire Systems Contractors (NACOSS), now part of the Security Industry Authority (SIA), and the British Standards Institution (BSI), which oversees compliance with BS 5266 (emergency lighting) and BS EN 12464-1 (lighting performance standards). The SIA maintains the National Register of security firms and operates a scheme for certified installers, while BSI certification indicates a company meets rigorous quality and safety standards. Additionally, the Institution of Lighting Professionals (ILP) represents specialists in lighting design and installation, and many reputable installers hold membership or recognition from trade bodies like the Electrical Contractors' Association (ECA) or National Inspection Council for Electrical Installation Contracting (NICEIC), which also oversee electrical safety compliance. These accreditations mean a provider has been independently assessed, carries appropriate insurance, follows industry best practice, and maintains ongoing professional standards.

To verify a provider's credentials, check whether they appear on the relevant register—the SIA National Register for security-specific work, NICEIC or ECA listings for electrical competence, or the BSI database for standards certification. Request their accreditation numbers and verify them directly with the issuing body rather than relying solely on the company's website. Ask for evidence of public liability insurance (typically £1–6 million for this work) and employer's liability insurance, as accredited providers must maintain current coverage. You can also ask for references from recent clients and whether they hold relevant qualifications such as Level 3 NVQs in security systems installation or electrical installation. This verification matters because accreditation assures you the work will be safe, compliant with building regulations and the Health and Safety at Work Act, and performed by trained professionals—
