What government-registered Competent Person status actually means when you hire an electrician.
Anyone can call themselves an electrician. Far fewer can produce a current government-recognised registration number, and even fewer can self-certify your work to Building Control. This page explains what NAPIT membership 66245 actually delivers when you hire us — the certificates, the warranty, the legal cover, and the route you have if anything ever goes wrong.
NAPIT is one of the UK’s government-authorised Competent Person Schemes for the electrical trade, sitting alongside NICEIC, ECA, ELECSA and STROMA. The schemes were introduced under Part P of the Building Regulations to give homeowners a way to identify electricians who have been independently checked — and to give the installers themselves a legal route to certify their own work.
To join NAPIT and stay on the register, every member is independently audited every year against a defined technical standard. The audit covers test equipment calibration, certification quality, BS 7671 knowledge, insurance cover, and an on-site assessment of recent work. If a member fails, they come off the scheme. The number on our certificates — 66245 — is only valid for the next 12 months between audits, then it gets re-earned.
That’s the difference between a logo on a van and a real registration: the logo can stay there forever, the number gets re-checked annually.
66245 is DS Electrical Installations (SW) Ltd’s NAPIT registration number. It identifies our company on the public register at napit.org.uk and on every Electrical Installation Certificate, EICR, Minor Works Certificate, and Building Regulations Compliance Certificate we issue.
Our scope under 66245 covers domestic and commercial electrical installation, inspection and testing, and certification — rewires, consumer-unit replacements, EV charger circuits, EICRs, fault-finding, and all notifiable Part P work in dwellings.
Verify before booking. Search ‘DS Electrical’ or ‘66245’ at napit.org.uk and you’ll find our company profile, the registered address, and the scope of work we’re authorised for. If a number doesn’t check out, that’s a red flag — not just for us, for any contractor.
Part P of the Building Regulations is the legal framework for domestic electrical safety in England and Wales. It came into force in January 2005 and applies to all fixed wiring inside dwellings — not portable appliances, not extension leads, but anything wired into the building.
Certain categories of work are notifiable, meaning they must be registered with the local authority Building Control before being signed off:
You have two routes to get notifiable work signed off legally:
Both routes are equally legal. Route 2 is faster, cheaper, and the standard for any reputable electrician working in dwellings.
When we finish a notifiable job under our 66245 registration, you receive the following — in writing, with your name and address on every document:
That stack of paper isn’t just admin — it’s what protects the value of your home, satisfies your insurer, and clears conveyancing on the day you sell.
Genuine accreditations are designed to be checked. Here’s the procedure:
The same approach works for any contractor — NICEIC have a checker at niceic.com, TrustMark at trustmark.org.uk, CHAS at chas.co.uk. If a tradesman lists a scheme name and the search returns nothing, ask why before paying a deposit.
Search the NAPIT registerMost jobs go cleanly. If one ever doesn’t, the NAPIT scheme gives you a clear, published procedure — and we’d rather you used it than stew in silence:
Most cowboy outfits can’t accept this level of accountability — which is why most of them aren’t registered with anyone.
Our full complaints policyBoth are UK government-authorised Competent Person Schemes for electricians, alongside ECA, ELECSA, and STROMA. They sit at the same level under Part P of the Building Regulations — a NAPIT-registered contractor and a NICEIC-registered contractor have equivalent legal authority to self-certify domestic electrical work. The schemes differ in branding, audit detail, and member fees, but a Building Control office or solicitor will accept paperwork from either equally.
No — swapping a like-for-like light fitting on an existing circuit is non-notifiable maintenance and does not require Part P notification. Part P notification is required when you add a new circuit, replace a consumer unit or fuse board, or carry out fixed wiring work in a special location such as a bathroom (Zone 0/1/2) or outdoors. If you’re unsure, ask the electrician before they start — any honest contractor will tell you whether the job is notifiable.
They cannot self-certify Part P work. To stay legal, the homeowner must apply directly to the local authority Building Control before work starts and pay an inspection fee (typically £200–£400) plus wait for inspection appointments — which slows the job. The work must still be tested and certified to BS 7671 by someone competent. The cheaper option is almost always to use a Competent Person scheme member who handles notification at no extra charge.
No. Part P applies to all dwellings in England and Wales regardless of tenure — rented, owner-occupied, leasehold, or HMO. A landlord arranging electrical work in a let property has the same Building Regulations obligations as a homeowner, plus separate landlord duties under the Electrical Safety Standards in the Private Rented Sector (England) Regulations 2020 which require a five-year EICR. Using a Competent Person scheme member covers both at once.
