Can electricians in the UK legally self-certify their own work?
Yes, qualified electricians in the UK can self-certify their own electrical work, but only if they are registered with a government-approved Competent Person Scheme (CPS) such as NICEIC, NAPIT, or ELECSA. This allows them to carry out and sign off notifiable work without needing to involve local authority building control. This process is part of ensuring domestic electrical installations are safe and comply with Part P of the Building Regulations.

What is self-certification in electrical work?
Self-certification means an electrician can legally approve their own work after completing certain types of electrical installations. This is only allowed if they are a registered member of a Competent Person Scheme. The purpose is to reduce unnecessary delays, costs, and paperwork by allowing trusted professionals to certify their work as safe and compliant.
The types of jobs that fall under notifiable work include installing new circuits, replacing consumer units and rewiring bathrooms or kitchens. Electricians who are not part of a CPS must notify building control, which will often require an inspection and charge a fee.
What is a Competent Person Scheme and how does it work?
A Competent Person Scheme is a government-backed initiative that gives registered professionals the authority to self-certify their own electrical work. Organisations such as NICEIC, NAPIT, ELECSA, Stroma Certification, and BSI Kitemark assess electricians for their skills, qualifications, and knowledge of the Wiring Regulations (BS 7671).
Once an electrician passes the assessment and joins a CPS, they are legally allowed to issue an Electrical Installation Certificate (EIC) or Minor Works Certificate when they complete notifiable work. This confirms that the work meets current safety standards and building regulations.
Who can register for a Competent Person Scheme?
To join a CPS, electricians must hold relevant qualifications such as an NVQ Level 3 in Electrical Installation and demonstrate competence in areas like fault diagnosis, consumer unit installation and circuit protection. They must also pass an on-site assessment by the scheme provider.
Most schemes charge annual membership fees and require regular assessments to maintain registration. This ensures continued compliance with the Electrotechnical Assessment Specification (EAS) and keeps electricians up to date with regulatory changes.
What electrical work needs to be certified?
The government classifies electrical work into two categories: notifiable and non-notifiable.
Notifiable work includes:
Installation of new circuits
Replacement or upgrading of consumer units
Electrical work in special locations such as bathrooms and kitchens
Outdoor electrical installations
Non-notifiable work includes:
Replacing existing sockets and light fittings
Adding sockets or lights to an existing circuit
General repairs and maintenance
Notifiable work must be certified. If the electrician is not CPS-registered, the job must be approved by a local building control officer.
Pro Tip: Keep all your electrical certificates in a safe place — especially if you’re planning to sell your home.
Missing paperwork can delay sales, raise red flags during surveys, or even knock down your property value.

What happens if the work is not certified?
If electrical work is not certified, it may be considered non-compliant under Part P of the Building Regulations. This can cause significant issues when selling the property, applying for home insurance or following up on legal liabilities.
Homeowners who hire non-registered electricians for notifiable work may end up paying for building control inspections or face penalties. It is always safer to hire a registered electrician who can provide the necessary certificates without involving the council.
Can homeowners check if their electrician is CPS registered?
Yes, homeowners can and should check an electrician’s registration status before any work begins. Here’s how:
Ask to see their Competent Person Scheme ID card
Look them up using the online member search tools provided by NICEIC, NAPIT or ELECSA
Ask for their scheme registration number and verify it directly with the provider
By confirming these details, homeowners can avoid delays, extra costs and ensure the work meets all safety and legal requirements.
Is CPS membership required by law?
Electricians are not legally required to join a CPS, but without it, they cannot self-certify. That means they will need to submit building notices and work under the oversight of local building control, which is more expensive and time-consuming.
Some electricians prefer this route, especially if electrical work is not their main business activity. In these cases, defined competence self-certification schemes may apply for professionals like plumbers or kitchen installers who occasionally carry out electrical work.
What is third-party certification?
Third-party certification is another legal route. It involves a registered third-party certifier inspecting and testing work carried out by someone who is not CPS-registered. The third-party inspector must be appointed before the work begins and must check compliance on completion.
This method provides flexibility but still ensures that notifiable work meets Part P standards. It is particularly useful for property owners who have had work done by non-registered tradespeople but still need the legal paperwork.
How does this relate to Part P of the Building Regulations?
Part P is the section of the Building Regulations that deals with electrical safety in dwellings. It sets the legal requirement for work to be designed and installed to protect people from fire and electric shocks.
Self-certification, third-party certification and building control approval are the three accepted routes for complying with Part P. Choosing the right option depends on whether the electrician is registered and the nature of the electrical work involved.
Why does this matter for property sales and insurance?
Work that is not certified might not show up on the legal documents during a property sale. This can delay transactions or reduce the property’s value. Insurers may also reject claims linked to uncertified electrical faults, particularly if they result in fire or injury.
Hiring a CPS-registered electrician and obtaining proper certification avoids these risks. It also reassures future buyers that electrical work has been done legally and safely.
Pro Tip: Always ask your electrician for their scheme registration number before work begins.
It saves time, hassle, and ensures your job can be legally self-certified without calling in Building Control. It catches small issues before they turn into shutdowns — and keeps you compliant with safety regs.

FAQs
Do all electricians need to be Part P registered?
Not all electricians are required to be Part P registered, but those who carry out notifiable work in domestic settings must comply with Part P of the Building Regulations. The easiest way to do this is through membership in a Competent Person Scheme, which allows them to self-certify. Without registration, they must apply to building control for approval.
Is it legal to do DIY electrical work in the UK?
Yes, but only for certain non-notifiable tasks. Homeowners can replace sockets, light switches or install light fittings on existing circuits. Anything that involves installing new circuits, consumer unit replacements or electrical work in kitchens or bathrooms must either be done by a CPS-registered electrician or approved by building control.
How much does it cost to notify building control if my electrician is not registered?
The cost of building control notification varies depending on the local authority, but fees can range from £150 to over £500 per project. These costs include inspections before and after the work is carried out to confirm safety and compliance.
What kind of certificate should I receive after electrical work?
For notifiable work, you should receive an Electrical Installation Certificate (EIC). For smaller changes or additions, a Minor Electrical Installation Works Certificate (MEIWC) may be issued. These confirm the work has been tested and complies with BS 7671 and Part P.
Can I sell my home if some electrical work is not certified?
You can, but it may delay the process or reduce your property’s value. Buyers and their solicitors often ask for proof that electrical work complies with regulations. Lack of certification might lead to renegotiation or requests for indemnity insurance. It is better to ensure all notifiable work is properly signed off and documented.
