The short answer
- Both are competent person schemes letting you self-certify notifiable electrical work.
- You need appropriate qualifications, a qualified supervisor, and calibrated test equipment.
- Assessment includes inspection of your completed work and your certification paperwork.
- Reassessment is annual.
- The two are broadly equivalent, choose on cost, support and what your customers recognise.
What you need before applying
Qualifications in electrical installation and in inspection and testing, and current knowledge of BS 7671.
A qualified supervisor, in a sole trader business that is you, and you must meet the criteria personally.
Calibrated test equipment, with evidence of calibration. This catches people out; assessors check it.
Insurance and a complaints procedure.
The assessment
An assessor visits, reviews your paperwork and inspects completed work, typically a job you have recently finished.
They are checking that the installation complies, that you tested properly, and that your certificates are completed correctly. Paperwork failures are as common as workmanship failures, so get your certification in order before booking.
Choosing between them
Broadly equivalent for self-certification purposes. Differences are in fees, technical support, and brand recognition. NICEIC is more widely known to consumers, NAPIT covers a broader range of trades under one registration.
Afterwards
Annual reassessment. Ongoing certification for every notifiable job. Keep your test equipment calibrated and your paperwork current, and it is straightforward.
