What is NICEIC

Full definition

NICEIC — the National Inspection Council for Electrical Installation Contracting — is a UK certification body that assesses and approves electrical contractors against technical standards set out in BS 7671 (the IET Wiring Regulations). It was founded in 1956 and is one of the oldest and largest bodies in the domestic and commercial electrical sector.

NICEIC is designated by the Secretary of State as a Government-Authorised Competent Person Scheme operator for Part P of the Building Regulations (England). Part P requires that certain electrical installation work in dwellings either be notified to the local authority before work begins, or be carried out by a contractor enrolled in an approved Competent Person Scheme. NICEIC operates two principal approval tiers relevant to domestic work:

• Approved Contractor: covers the full scope of electrical work in domestic and commercial premises and requires a higher level of technical assessment.
• Domestic Installer: limited to electrical installation work within dwellings; suitable for electricians working exclusively in the domestic sector.

Approved businesses may self-certify completed notifiable work by issuing an Electrical Installation Certificate (EIC), bypassing the requirement to submit a Building Notice to the local authority. This self-certification is a statutory mechanism under the Building Regulations 2010 (as amended).

Why it matters (legal requirement and trust)

Part P of the Building Regulations makes it a legal requirement that notifiable electrical installation work in dwellings is either notified to the local building control authority or carried out by an enrolled member of a Competent Person Scheme such as NICEIC. Undertaking notifiable work outside these routes is a contravention of the Building Regulations.

For property owners and landlords, using an NICEIC Approved Contractor provides assurance that the work is covered by a Minor Electrical Installation Works Certificate or a full Electrical Installation Certificate — documentation that is increasingly required by mortgage lenders, insurers, and buyers at the point of conveyancing.

For contractors, NICEIC approval is a credibility signal that supports tendering for commercial and local authority contracts, where demonstrable third-party competence assessment is often a procurement requirement.

How approval works

An electrical contracting business applies to NICEIC and is assessed by a qualified NICEIC Assessor. The assessment process typically includes:

1. Technical inspection of recent installations: The assessor inspects completed work on site to verify it meets BS 7671 and relevant Approved Document standards.
2. Review of test documentation: Inspection and test records are examined for accuracy and completeness.
3. Assessment of technical knowledge: The responsible person (the Qualified Supervisor) may be interviewed or tested.
4. Ongoing surveillance: Enrolled businesses are subject to periodic re-assessment visits to maintain approval.

Upon successful enrolment, the business and its qualified engineers appear in the NICEIC public register, searchable at niceic.com. Approved Contractors are also TrustMark registered via NICEIC as a Scheme Provider.
