# Distribution Boards: Trade Body Accreditation

In the UK, Distribution Board installation and maintenance is overseen by several key regulatory bodies and trade organisations. The most significant is the National Qualified Examiners Register (NQER), which certifies engineers who test and certify electrical installations, including distribution boards. The Institution of Engineering and Technology (IET) sets the standards that underpin much of this work, particularly BS 7909 and BS 7671 (the 18th Edition Wiring Regulations). Additionally, the NICEIC and the Electrical Contractors' Association (ECA) maintain registers of approved contractors and electricians who have demonstrated competence in safely installing and servicing distribution boards. For commercial premises, competence under the Building Regulations and the Health and Safety at Work etc. Act 1974 is mandatory. Understanding which body has accredited your provider gives you clarity on what standard they've been assessed against and how recently they were last checked.

To verify a provider's credentials, you should ask for their certification number and confirm it directly with the issuing body's online register. NICEIC and the ECA both maintain searchable databases on their websites where you can cross-reference a company's registration status, the scope of their work they're approved for, and when their accreditation expires. It's also worth checking whether they hold valid Public Liability Insurance and, for work on live systems, whether they're registered with the NQER if certification testing is involved. This verification matters because an unaccredited electrician may lack formal training in the latest safety standards, may not carry adequate insurance if something goes wrong, and their work may not meet Building Control requirements, leaving you exposed to liability or enforcement action from local authorities.

Accredited providers typically charge 10 to 25 percent more than unaccredited alternatives, reflecting the cost of their training
