A comparison of the two main competent person schemes — costs, requirements, reputation, and which is right for you.
When you are ready to register with a competent person scheme to self-certify your electrical work under Part P, the two biggest names you will encounter are NICEIC and NAPIT. Both are government-approved competent person schemes that allow you to self-certify notifiable electrical work in domestic properties, but they differ in history, cost, and reputation.
This guide provides an honest, factual comparison of the two schemes to help you decide which is the better fit for your business. Both are legitimate and respected within the industry, so the right choice depends on your priorities, budget, and business needs.
NICEIC (National Inspection Council for Electrical Installation Contracting) was established in 1956 and is the oldest and largest electrical contractor registration scheme in the UK. It is now managed by Certsure and has been the dominant name in electrical scheme registration for decades.
NICEIC offers two main registration levels for electricians:
The Domestic Installer scheme is the most common choice for electricians starting out in self-employment or running a small domestic business. The Approved Contractor scheme is more suitable for larger businesses or those working on commercial projects.
NICEIC Domestic Installer registration typically costs between 500 and 700 pounds per year. The Approved Contractor scheme is more expensive, typically 700 to 1,000 pounds per year. There is also an initial assessment fee when you first join, which is separate from the annual registration fee. Costs can vary based on the size of your business and the number of operatives.
NAPIT (National Association of Professional Inspectors and Testers) is a newer scheme that has grown significantly since its establishment. It has positioned itself as a cost-effective alternative to NICEIC while offering the same legal standing and government approval as a competent person scheme.
NAPIT also offers tiered registration for different types of electrical work:
NAPIT Domestic Installer registration typically costs between 400 and 600 pounds per year, making it generally cheaper than NICEIC. As with NICEIC, there is an initial assessment fee when joining. NAPIT has been competitive on pricing, which is one of the main reasons for its growing membership.
Here is a direct comparison of the two schemes across the factors that matter most to working electricians.
Both schemes require the same minimum qualifications. You must hold a current 18th Edition Wiring Regulations certificate and an Inspection and Testing qualification (2391). Both also require you to have adequate public liability insurance and to demonstrate competence through an assessment of your work.

18th Edition (2382)
Both NICEIC and NAPIT require the 18th Edition as a minimum qualification.
Both schemes conduct annual assessment visits. The process is broadly similar: an assessor visits your premises, reviews your paperwork and certification records, checks your test equipment calibration, and inspects a sample of your recent work. Both schemes use the assessment as an opportunity to provide guidance and ensure standards are maintained.
NAPIT is generally cheaper than NICEIC by 100 to 200 pounds per year for domestic installer registration. Over five years, this can represent a saving of 500 to 1,000 pounds. However, costs change over time and there may be promotional offers, so it is worth checking current prices directly with both schemes.
NICEIC has significantly higher brand recognition among the general public. The NICEIC name and logo are widely recognised by homeowners, estate agents, and property managers. NAPIT is well known within the trade but has lower public awareness. If customer perception is important to your business, this is worth considering.
Both schemes offer online directories where homeowners can search for registered electricians in their area. The NICEIC Find a Contractor tool is more established and receives more traffic, which can generate leads for registered members. NAPIT also offers a similar tool, though with lower traffic volumes.
NAPIT is often praised by members for its customer service and responsiveness. As a smaller organisation, members sometimes report feeling better supported and less like a number. NICEIC, being larger, can sometimes feel more bureaucratic, though experiences vary and both schemes receive positive feedback from members.
A crucial point that is sometimes overlooked is that both NICEIC and NAPIT require exactly the same qualifications for membership. There is no difference in the competence expected of a NICEIC registered electrician versus a NAPIT registered electrician. Both must hold:
Both schemes also conduct an initial assessment of your competence before accepting you as a member. This typically involves an assessor reviewing your qualifications, inspecting your test equipment, and examining examples of your recent work and certification.

Inspection & Testing (2391)
The 2391 qualification is essential for joining either NICEIC or NAPIT.
The honest answer is that either scheme will serve you well. Both are government-approved, both carry the same legal standing, and both allow you to self-certify notifiable work under Part P. Your decision should be based on your specific priorities.
Other Schemes
NICEIC and NAPIT are the two largest schemes, but they are not the only options. ELECSA is another government-approved competent person scheme for electricians. It is worth checking their fees and benefits as well before making your final decision.
The process for joining either scheme is broadly similar. Here is what to expect when applying for domestic installer registration with either NICEIC or NAPIT.
The initial assessment typically takes place within a few weeks of your application being submitted. The assessor will want to see examples of your recent work, so it is helpful to have photographs and copies of certificates you have issued. They will also check that your test equipment is within its calibration date.
Both NICEIC and NAPIT require an annual assessment visit to maintain your registration. This is a quality assurance measure to ensure that registered electricians continue to work to the required standard.
The annual assessment is not something to be nervous about if you are working to a good standard. Assessors are experienced electricians themselves and approach the visit as a supportive process rather than a punitive one. They will provide feedback and guidance on any areas for improvement.
Failing an Assessment
If significant issues are found during an assessment, the scheme may require corrective action within a specified timeframe. In serious cases, registration can be suspended or withdrawn. However, this is rare for electricians who are working conscientiously and maintaining their qualifications.
