Can Any Electrician
Install an EV Charger?

Not legally. UK EV charger installs require a NAPIT or NICEIC registered electrician with specific EV training. For OZEV grant eligibility the installer must also be on the OZEV approved installer register. Here are the qualifications that matter and why they are required.

Quick answer

No. UK EV charger installs must be carried out by a qualified electrician registered with a competent persons scheme such as NAPIT or NICEIC and notified under Part P of the Building Regulations. For OZEV grant funding (where eligible), the installer must additionally be on the OZEV approved installer list. Many older domestic installations also require Type B RCD protection which not all general electricians stock or know how to specify.

Building Regs Notification

EV charger circuits must be notified under Part P of the Building Regulations. Non-compliant installs invalidate insurance and home sale legal packs.

NAPITor NICEIC

Required Registration

Installers must be registered with a competent persons scheme such as NAPIT or NICEIC to legally self-certify Part P notifiable work.

OZEVlist

Grant-Approved

For OZEV grant eligibility (£350 off for eligible properties), installers must additionally be on the OZEV approved installer register.

EV-Specific Protection

Many UK home EV charger installs require Type B RCD or RDC-DD protection for DC fault current detection. Not standard kit for all electricians.

What qualifications a UK EV charger installer needs

EV charger installation is notifiable electrical work under Part P of the Building Regulations. That means the installer must either be registered with a competent persons scheme (NAPIT, NICEIC, ELECSA, NAPIT, Stroma) or have the work signed off by Building Control with a separate fee. In practice, almost all UK installs go through registered electricians who can self-certify.

Why a general electrician is not always enough

Modern EV chargers introduce two new technical requirements that not all general domestic electricians have hands-on experience with.

First, DC fault current protection. EV chargers can produce DC fault currents that standard Type AC RCDs cannot detect. UK installations require either a Type B RCD or an RDC-DD device built into the charger or upstream of it. Selecting and specifying the right protection requires up-to-date knowledge of the 18th Edition wiring regulations and recent amendments.

Second, load management. UK domestic supplies are limited to 60 to 100A per property. Adding a 32A EV charger circuit alongside an electric shower, oven and other high-load appliances can exceed the available supply during peak times. Modern chargers include load management options (dynamic load balancing) but configuring them properly requires the installer to understand the household's existing load profile.

OZEV approved installers

The Office for Zero Emission Vehicles (OZEV) operates the EV chargepoint grant scheme worth up to £350 toward an eligible install. To claim the grant, the installer must be on the OZEV approved installer register. Approval requires the installer to demonstrate competence with EV-specific kit, complete OZEV-recognised training and meet ongoing standards. Not all NAPIT-registered electricians are OZEV approved.

Even where the OZEV grant does not apply (most homeowners cannot claim it under the current rules which only cover flats, rentals and certain low-income applications), choosing an OZEV-approved installer is a useful quality signal because they have demonstrated EV-specific competence beyond general electrical work.

Authoritative context

UK EV charger installation rules are set by Part P of the Building Regulations 2010 (as amended) and BS 7671 (the IET Wiring Regulations, currently in 18th Edition). Notifiable electrical work in dwellings must either be carried out by a registered competent person or notified to and inspected by Building Control. The Office for Zero Emission Vehicles (OZEV) maintains the approved installer list for grant-funded installations. Trade bodies including NAPIT, NICEIC and the Electrical Safety Council publish ongoing technical guidance specific to EV charger installation.

Typical UK EV charger install costs

Standard 7kW install (with grant)
OZEV-eligible install with £350 grant deducted. Standard cable run under 10 metres.
£800-£1,200
Standard 7kW install (no grant)
Owner-occupied house not eligible for OZEV grant. Standard install. Most common scenario.
£900-£1,500
Complex install (long run, CU upgrade)
Cable run over 15 metres, consumer unit upgrade required, three-phase considerations.
£1,500-£2,500

Typical UK EV charger install process

1

Free site survey

Installer visits to assess parking location, cable route, consumer unit capacity and existing earthing arrangement. Quote provided.

2

DNO notification

Installer notifies the Distribution Network Operator (UK Power Networks, National Grid, etc) of the new EV load. Required for installs over 16A.

3

Install day (3 to 6 hours)

Cable run, charger mounted, consumer unit work as needed, Type B RCD or RDC-DD protection fitted, charger commissioned and tested.

4

Documentation handover

Electrical Installation Certificate (EIC) issued. Building Control notification submitted. Charger registered with OZEV if grant applicable.

How to verify your installer is qualified

Check NAPIT or NICEIC registration

Both bodies maintain searchable online registers. The installer should give you their registration number to verify.

Ask about Type B RCD experience

Confirm the installer understands DC fault current protection and uses appropriate Type B RCDs or RDC-DD devices on EV circuits.

Confirm OZEV approval if claiming grant

OZEV publishes the approved installer list on gov.uk. The grant is only valid if the installer is on the list.

Get the certificate after install

You should receive an Electrical Installation Certificate (EIC) and Building Control compliance certificate. Keep these for property records.

General domestic electrician

  • Part P registered (most are)
  • Standard wiring experience
  • May not stock Type B RCDs
  • Limited EV-specific training
  • Cannot self-certify OZEV grants
  • Can do install but quality varies

EV charger specialist

  • Part P registered
  • OZEV approved installer
  • Routinely fits Type B RCDs and RDC-DD
  • EV-specific manufacturer training
  • Can claim OZEV grant on your behalf
  • Specialist in load management setup

Frequently asked

Common questions

Can my regular electrician install an EV charger?
Possibly but not necessarily. They need to be Part P registered (most domestic electricians are), familiar with Type B RCD or RDC-DD protection (not all are) and capable of submitting the Building Control notification. For OZEV grant claims they additionally need to be on the OZEV approved installer register. Many general electricians can do the work but EV specialists tend to deliver cleaner installs with the right protective equipment first time.
What happens if my installer is not OZEV approved?
The install can still be legal and safe provided they are Part P registered. However, you cannot claim the OZEV grant (currently up to £350 for eligible properties). For most owner-occupied houses the grant does not apply anyway under current rules so this is often a non-issue. If you are eligible for the grant, insist on an OZEV approved installer because grant claims fail without that approval.
What documentation should I receive after an EV charger install?
An Electrical Installation Certificate (EIC) covering the new circuit. A Building Control compliance certificate confirming Part P notification. The charger manufacturer's commissioning certificate. The DNO notification confirmation. If you claimed the OZEV grant, the grant claim documentation. Keep all of this for property records and any future home sale legal pack.
Why does an EV charger need a Type B RCD?
EV chargers can produce DC fault currents that standard Type AC RCDs cannot detect. A Type B RCD (or RDC-DD device) detects both AC and DC fault currents, providing complete shock protection. UK regulations under BS 7671 require this level of protection on EV circuits. Many older homes do not have Type B RCDs in their consumer unit, so the protection is typically added at the EV charger circuit rather than as a whole-board upgrade.
How do I find an OZEV approved installer?
The Office for Zero Emission Vehicles maintains a searchable register at gov.uk. You can filter by postcode to find approved installers in your area. Ask installers for their OZEV registration number when getting quotes. Cross-reference against the gov.uk register before committing. We are NAPIT registered and OZEV approved across Bedford, Milton Keynes, Northampton, Wellingborough and Luton.
