BS 7671 Section 722 — Key Requirements
- Regulation 722.411.4 — PEN fault protection required for EV chargers on PME supplies installed outdoors or in accessible garages. Satisfied by a WCED device or TT earth electrode.
- Regulation 722.531 — RCD protection required. Type A is sufficient for most installations; Type B (DC-sensitive) may be needed depending on the vehicle's on-board charger.
- Regulation 722.537 — Means of isolation must be provided for the EV circuit.
- Cable sizing — EV charging is a continuous load (100% load factor). Cables must be sized accordingly.
- Labelling — EV supply circuits must be labelled at both the consumer unit and the charge point.
Smart Charge Point Regulations 2021
All new home charge points sold or installed in Great Britain must be "smart" — capable of time-of-use response, demand-side management, a randomised delay to prevent simultaneous charging spikes, and communication via open standards. In practice, this means all new units you buy today are compliant.
Under the Smart Charge Point Regulations, charge points must default to charging during off-peak hours (00:00–07:00 and 11:00–16:00) unless the user actively changes this. This is why new chargers prompt you to set a charging schedule during setup.
Pre-Installation Checklist
- Confirm earthing type (PME/TN-S/TT) — determines whether WCED is needed
- Check consumer unit has a spare way and sufficient incoming capacity
- Confirm charge point is on OZEV approved product list (if claiming grant)
- Confirm installer is OZEV-authorised and Part P registered
- Agree PME protection approach with installer
- Confirm RCD type (Type A vs Type B) for your vehicle
- Request Electrical Installation Certificate and Building Regulations Compliance Certificate on completion
Frequently Asked Questions
Does my EV charger installation need Building Regulations approval?
Yes, in England and Wales. EV charger installation is notifiable electrical work under Part P. It must be carried out by a Part P registered electrician (NICEIC, NAPIT, ELECSA etc.) who self-certifies, or notified to local building control. You should receive a completion certificate.
Is a Type B RCD always required?
No — a Type A RCD is sufficient for most installations. A Type B is required if your vehicle's on-board charger can produce smooth DC leakage above 6mA. Check your vehicle manufacturer's guidance. Some older Renault and Nissan models specify Type B.
What documentation should I receive after installation?
You should receive: an Electrical Installation Certificate (EIC), a Building Regulations Compliance Certificate (Part P, England and Wales), and OZEV grant confirmation if applicable. Keep these — you'll need them when selling your home.
