To become NICEIC registered you apply online for either the Domestic Installer scheme (dwellings only, Part P self-certification) or Approved Contractor (all installation work including commercial and industrial), name a Qualified Supervisor who holds a current BS 7671 qualification (City & Guilds 2382, 18th Edition) plus inspection and testing (City & Guilds 2391 or equivalent), and pass an on-site assessment. The assessor checks your certificates, calibrated test instruments, insurance and technical reference books, then inspects and tests a sample of your recent work against BS 7671. Registration is renewed by an annual assessment. NICEIC is operated by Certsure LLP and is government-authorised for Part P in England and Wales.
- Two main routes: Domestic Installer (dwellings, Part P) and Approved Contractor (full scope, commercial and industrial).
- Every registration needs a named Qualified Supervisor with C&G 2382 (18th Edition) and C&G 2391 inspection and testing, plus Level 3 or equivalent experience.
- The assessment covers paperwork, instruments, insurance, technical references and a real job on site.
- Non-conformances are common at first assessment and must be closed out before registration.
- Assessment is repeated every year; the cost is an entry fee plus an annual fee and per-notification charges.
What is NICEIC registration?
NICEIC registration is enrolment with a competent-person scheme, a government-authorised body that assesses electricians as competent to self-certify that their work complies with the Building Regulations. In England and Wales, that means Part P: a registered electrician notifies notifiable jobs to the scheme, which issues the compliance certificate and informs the local authority. See Part P notification explained for what counts as notifiable.
Registration is not a licence; there is no legal licensing of electricians in England and Wales. What it gives you is Part P self-certification, a listing on the Registered Competent Person Electrical register, and a third-party check on your competence that landlords, agents and main contractors increasingly ask for. NAPIT, STROMA and BSI run comparable schemes; see NICEIC vs NAPIT.
Which NICEIC route should I apply for?
| Domestic Installer | Approved Contractor | |
|---|---|---|
| Scope of work | Electrical work in dwellings and their outbuildings | All electrical installation work: domestic, commercial, industrial |
| Part P self-certification | Yes | Yes |
| Qualified Supervisor requirement | Current BS 7671 and inspection and testing qualifications; practical competence | As Domestic Installer, plus Level 3 qualification or equivalent and broader experience |
| Assessment sample | Domestic jobs | Jobs across the range of work you do |
| Typical applicant | Sole trader, small domestic firm | Contractors doing commercial, landlord portfolios, main-contractor work |
| Client recognition | Homeowners, letting agents | Facilities managers, tenders, main contractors specifying "NICEIC Approved Contractor" |
Domestic Installer is the right starting point for most sole traders whose work is houses and flats, including landlord EICRs. Approved Contractor is needed when clients specify it in tenders or you take on commercial and industrial work; the Qualified Supervisor is assessed more rigorously. You can upgrade later.
What qualifications does NICEIC expect?
The assessment is of competence, not paper, but in practice assessors expect the Qualified Supervisor to show:
| Qualification | What it covers | Why it matters at assessment |
|---|---|---|
| City & Guilds 2382 (18th Edition, BS 7671:2018) | Current wiring regulations | The assessor tests your work and certificates against BS 7671; you must hold the current edition |
| City & Guilds 2391 (or 2394/2395, or equivalent) | Initial verification and periodic inspection and testing | You are certifying test results; the scheme wants evidence you can test and interpret them |
| Level 3 electrical installation (C&G 2365, 2357, NVQ Level 3, or the AM2 route) | Installation practice, design and theory | Expected for Approved Contractor; strong evidence of competence for Domestic Installer |
Experience counts: a time-served electrician with a Level 3 NVQ and AM2 is exactly what the scheme is designed for, while someone with 2382 and 2391 but no installation qualification will be assessed harder on the practical side. BS 7671:2018+A4:2026 was published on 15 April 2026 and A2 is withdrawn on 15 October 2026; your 2382 does not expire, but the assessor expects your reference copy and your certificates to be current.
What happens at the NICEIC assessment visit?
The assessment is a visit by an NICEIC Area Engineer to your office or home and then to one or more jobs. Expect half a day to a day. The items below are what they consistently look at.
Certificates you have issued
Bring a sample of completed EICs, Minor Works certificates and, if you do periodic inspection, EICRs. The assessor reads them closely. Common problems are blank boxes, test results that look invented, no schedule of inspections attached to an EIC, the wrong form for the job, the BS 7671 edition not stated, and EICR observations coded without a regulation reference. The certificate must match the job actually done and, for notifiable work, the job you notified. If you have not yet issued many certificates, do some jobs and certify them properly before you apply. See EICR vs EIC and Minor Works: when to use it to be sure you are using the right form.
Test instruments and calibration
You need instruments covering continuity, insulation resistance, earth fault loop impedance, prospective fault current and RCD testing, plus a voltage indicator and proving unit. The assessor asks for calibration certificates or a documented ongoing accuracy check against a known reference. An instrument with no calibration record is one of the most frequent first-assessment non-conformances.
Insurance
Public liability insurance to the scheme's published minimum is required, and employers' liability insurance is a legal requirement if you employ anyone. Have the certificates ready.
Technical reference documents
You must hold current copies of BS 7671 and the IET On-Site Guide or relevant Guidance Notes, including Guidance Note 3 if you do periodic inspection. Electronic subscriptions are accepted; an out-of-date edition is a finding.
The sample job
The assessor visits at least one recent installation, checks it against the certificate you issued, and carries out their own inspection and testing: workmanship, correct protective devices, RCD protection where BS 7671 requires it (Regulations 411.3.3 for socket-outlets up to 32 A and 411.3.4 for domestic lighting), bonding, labelling, and that measured values agree with what you recorded. If the job was notifiable, they check it was notified.
What is the Qualified Supervisor?
The Qualified Supervisor (QS) is the named individual responsible for the technical standard of all work the registered business carries out and for the certificates it issues. Every registration must have one, and the QS is the person assessed. For a sole trader, you are the QS. In a firm, the QS must be an employee or principal who genuinely supervises the work and reviews certificates issued by others before they go out. See Qualified Supervisor sign-off explained.
What happens after the assessment?
Findings are recorded as non-conformances against the scheme's rules or BS 7671. Minor ones are closed by sending evidence, such as a calibration certificate or a corrected certificate; anything affecting safety on the sample job must be put right. Once the findings are closed, registration is confirmed and you appear on the register.
Registration then runs on an annual cycle: each year an assessor repeats the process with a sample of that year's jobs, and a registration that goes badly can be suspended until findings are cleared. Your certificates are reviewed by an outside engineer every year, which is why getting the paperwork right on every job matters more than getting it right for the assessment.
What does NICEIC registration cost?
NICEIC charges an application and assessment fee on entry, an annual registration fee that depends on the route and the size of the business, and a small charge per Part P notification; Approved Contractor costs more than Domestic Installer. Budget also for annual calibration, current copies of BS 7671 and the guidance notes, insurance, and any qualifications you still need. NICEIC publishes and revises its price list annually, so check the current figures.
Common first-assessment findings
| Finding | How to avoid it |
|---|---|
| Test instrument with no calibration evidence | Calibrate annually or keep a documented check against a reference unit |
| Incomplete certificates or missing schedules | Fill in every box; attach the schedule of inspections and schedule of test results to every EIC and EICR |
| Wrong certificate type for the job | New circuit or consumer unit change = EIC, never Minor Works |
| BS 7671 edition or amendment not stated | State the edition on every certificate and keep your reference copy current |
| RCD protection missing on the sample job | Apply 411.3.3 and 411.3.4 and record the RCD test results |
How Certio helps
Certio produces the EICR, EIC, Minor Works certificate and PAT records on the BS 7671 model forms and turns them into branded PDFs. Photograph the consumer unit and the circuit schedule drafts itself; point the phone camera at a Megger MFT-X1 and the reading goes straight into the schedule of test results, or dictate it while your hands stay on the probes. Suggested observation wording with the regulation reference is there for you to check and confirm. The judgement stays yours; the typing goes. Starter is free for 7 days, then £5 a month.
