NERS is administered by Lloyds Register Quality Assurance (LRQA) Limited, an independent business of the Lloyds Register, on behalf of the UK’s Distribution Network Operators (DNOs).

NERS assigned the entire accreditation process to LRQA, which has strengthened the procedure’s credibility and acceptance within the industry. A full list of NERS-accredited contractors is available to all on the LRQA website; depending on the scope of their accreditation, ICPs can carry out work such as designing new network connections, substation installation, civil works, cable laying and installing electrical switches and transformers (with voltage limits where applicable).

The introduction of accreditation enabled ICPs to compete in the contestable connections market, attracting more proficient ICPs to the industry.
