EV charger installation is electrical work and must be designed and certified correctly. In England, Part P of the Building Regulations covers electrical safety in dwellings. Many installers notify through a competent person scheme so you receive compliance paperwork without a separate building control application. Ask how notification will be handled before work starts, and keep certificates with your home records.
Part P is about dwelling electrical safety
Part P aims to protect people from fire and shock risks arising from electrical installations in dwellings. An EV circuit, consumer unit changes and outdoor equipment all sit inside that safety world even though the charger also has product-specific rules.
Wales, Scotland and Northern Ireland use different building standards frameworks. This guide focuses on the England Part P conversation that many homeowners meet first; always confirm the nation and local process that applies to your address.
- Ask which regulations apply to your nation.
- Do not treat Part P as a substitute for BS 7671 design quality.
- Refuse uncertified DIY board alterations for EV circuits.
Competent person schemes and building control
Registered competent person installers can often self-certify notifiable domestic electrical work and notify on your behalf. If your contractor is not doing that, building control involvement may be required. Clarify the route in the quote.
Scheme membership should be verifiable. A logo on a van is not enough; check the register and the exact competence categories claimed.
Paperwork that proves the job
Expect an Electrical Installation Certificate or equivalent documentation covering the new circuit and any altered board, plus Building Regulations compliance documentation where applicable. Manufacturer commissioning records for the charger help future warranty claims.
DNO notification or application evidence may sit alongside Building Regulations paperwork. They are related but not identical processes.
Survey and contract wording to insist on
Good quotes state whether notification is included, who submits it, and when you should receive copies. Ambiguous labour-only offers that leave certification vague are high risk.
If a consumer unit upgrade is provisional pending survey, the Part P and certification implications of that upgrade should be priced as a clear optional or provisional sum.
- Keep PDFs and paper copies together.
- Match serial numbers on certificates to the installed unit.
- Ask how defects found on survey change the notifiable scope.
Frequently asked questions
Is an EV charger always notifiable under Part P?
Domestic electrical work often is, depending on the nature of the alteration. Your installer should confirm the notification route for the exact scope at your address.
Can I install a wallbox myself?
Even if you are electrically capable, product instructions, earthing design, notification and insurance expectations make professional installation the normal safe path for most households.
What documents should I receive after install?
Electrical certification for the work done, Building Regulations compliance documentation where applicable, and charger handover information. Keep DNO related confirmations too.
Does Part P apply to a workplace charger?
Part P is aimed at dwellings. Commercial premises follow different regulatory and inspection frameworks, though BS 7671 design discipline still applies.
