Key Takeaways

  • 1EV charger installs combine several high-risk activities: drilling external walls, working at height, working outdoors in changing weather, isolating the consumer’s mains and commissioning a new circuit — a single generic RAMS will not cover them all.
  • 2BS 7671:2018+A4:2026 Section 722 governs EV charging installations. A4:2026 retains the PME-supply restrictions of Regulation 722.411.4.1 and now expressly distinguishes PME from PNB (TN-C-S where the neutral is bonded to earth only at the origin).
  • 3Regulation 722.421.1.7.201 in A4:2026 permits the AFDD requirement for final circuits supplying EV charging points to be relaxed where a risk assessment justifies it — the justification must be recorded.
  • 4CDM 2015 Regulation 15 applies even on a single-day domestic EV install: the contractor must plan, manage and monitor the work, and provide site-specific information to anyone affected.
  • 5EAWR 1989 Regulation 4 (systems, work activities and protective equipment) and Regulation 14 (work on or near live conductors) drive the safe-isolation and proving-dead elements of the method statement.
  • 6Customer property protection is part of the RAMS — dust sheets, drilling debris, drive-paving reinstatement and post-install commissioning evidence all belong in the method statement before work starts.

Why EV Installs Need Their Own RAMS

An EV charger installation is not a "small works" job. In a single visit an electrician will typically work at height to install an external unit, drill through the external fabric of the building, install and route a sub-main, isolate the consumer’s mains supply, modify the consumer unit (or fit a sub-board) and commission a new dedicated final circuit. Each of those activities has its own hazard profile, and each must be addressed in the method statement.

A generic "electrical installation works" RAMS is not adequate. The Health and Safety Executive expects the risk assessment to be specific to the task, the location and the people who may be affected — see the wider electrical RAMS template guide for the underlying framework, then layer the EV-specific hazards in this guide on top.

Statutory anchor

The Management of Health and Safety at Work Regulations 1999 Regulation 3 requires every employer (and self-employed person) to carry out a "suitable and sufficient" risk assessment. CDM 2015 Regulation 15 layers a planning, management and monitoring duty on top whenever the work is construction — which an EV install is.

EV-Specific Hazards and Control Measures

Below are the hazards that distinguish an EV charger install from a routine domestic addition. Each one must appear in the RAMS with a named control measure and the residual risk recorded.

  • Drilling external walls — cavity collapse, hidden cables/pipes, masonry strike, dust inhalation. Control: cable/pipe detector pre-scan, dust mask (FFP3 for silica), drill on slow speed, debris collection sheet.
  • Working at height — most charge points fit 1.0–1.5 m above ground, but external sockets at first-floor level or wall-mounted units on rendered upper walls require a step or low-level platform. See working at height for electricians for the full control set.
  • Working outdoors — wind, rain, cold, low light. Control: defer commissioning if rain ingress risk to opened enclosure; use IP-rated temporary lighting; suspend torque-critical tasks below 5°C unless manufacturer permits.
  • PME/PNB open-PEN risk — a broken supply neutral can put the consumer’s earthed metalwork at supply voltage. Section 722.411.4.1 of BS 7671:2018+A4:2026 prohibits relying on a TN-C-S/PME earth for the EV unless specific conditions are met (e.g. integral open-PEN protection device certified for EV use, or installation of an earth electrode and conversion to TT for the EV final circuit).
  • PNB distinction — A4:2026 now expressly separates PNB (Protective Neutral Bonding, TN-C-S where the neutral is bonded to earth only at the origin) from PME (Protective Multiple Earthing). The risk assessment must record which arrangement is present — see the A4:2026 TN-C-S / PNB earthing guide for the wording change.
  • Isolation of the consumer’s mains — the only safe way to install a new sub-main is with the main switch open. Control: follow the safe-isolation procedure in our safe isolation method statement; lock-off and tag the main switch; prove dead with a GS38-compliant tester proved against a known source before and after.
  • Customer property protection — dust sheets in the consumer’s home, board protection where ladders are placed on driveways, reinstatement of any disturbed paving or render. Damage to property is the single most common cause of post-install dispute.
  • Live commissioning of the new circuit — once the supply is re-energised, the charge point must be commissioned in accordance with the manufacturer’s instructions and BS EN 61851-1. Control: PPE rated for the prospective fault current, ELV test instruments, and a written commissioning sequence in the RAMS.

BS 7671 Section 722 — Regulations You Must Cite

Section 722 ("Electric vehicle charging installations") is the special-location chapter for EV charging in BS 7671:2018+A4:2026. The method statement should reference the regulations that apply to the specific installation and record the design decisions taken under each one.

  • Regulation 722.411.4.1 — PME supplies: a PME earth must not be used for the EV charging point unless one of the listed conditions is met (integral open-PEN device, separate TT arrangement for the EV final circuit, or other measure permitted by the regulation).
  • Regulation 722.421.1.7.201 — AFDD: an AFDD is required for the final circuit supplying the EV charging point unless the designer can justify omission on the basis of a documented risk assessment. See the A4:2026 AFDD changes guide for the exemption wording.
  • Regulation 722.531.3 — RCD protection: each EV charging connection point must be protected by an RCD of Type A or higher; Type B is required where the charge point does not provide its own DC fault current detection. The manufacturer’s data sheet for the charge point must be consulted before specifying the RCD type.
  • Regulation 722.55.101 — plug, socket and connector standards: the connection point must comply with the relevant part of BS EN 62196.
  • Regulation 722.512.2 — external influences: enclosures must be rated for the location (typically IPX4 minimum for outdoor units; IK rating for impact resistance).

IET Code of Practice (5th Edition)

The IET Code of Practice for Electric Vehicle Charging Equipment Installation (5th Edition) sits alongside BS 7671 and provides the practical detail — site survey, load assessment, DNO liaison, smart-charging compliance under the Electric Vehicles (Smart Charge Points) Regulations 2021, and earthing arrangement selection. The method statement should record that the design has been carried out in accordance with the Code of Practice.

04 · Method Statement Guide

DNO Notification and Load Assessment

EV charge points are connected generation- and load-relevant equipment. Most domestic 7 kW chargers require post-installation notification to the DNO under Engineering Recommendation G98 (per phase). Higher-power or three-phase installations trigger G99 pre-notification, which must be applied for and approved before energisation.

  • G98 — connect-and-notify for single 16 A per phase devices. Notify the DNO within 28 days of energisation using the standard G98 form. Most 7 kW domestic chargers fall within this category.
  • G99 — pre-notify for higher-rated or multi-charge-point installations. Approval must be obtained from the DNO before commissioning. Allow 4–12 weeks depending on the DNO.
  • Maximum demand assessment — add the EV charge point to the dwelling’s existing maximum demand calculation. If the available supply capacity is insufficient, either a load-management/smart-charging solution or a supply upgrade is required — see cable size for EV charger for the cable selection side of this.
  • Smart charging compliance — the Electric Vehicles (Smart Charge Points) Regulations 2021 require domestic and workplace charge points sold or installed in Great Britain to meet smart functionality, randomised delay and default off-peak charging requirements. The installer must verify the unit being installed is compliant.

Commissioning and Inspection & Testing

The RAMS must end with a documented commissioning sequence. An EV charge point is a new circuit and therefore requires an Electrical Installation Certificate (EIC) for the addition, plus the EV-specific commissioning checks called for by Section 722 and the IET Code of Practice.

  • Conformity check — confirm the unit is to the relevant part of BS EN 61851 and BS EN 62196, has a current declaration of conformity, and matches the smart-charging requirements where applicable.
  • Inspection — visual inspection per BS 7671 Chapter 64, paying particular attention to ingress protection, mechanical protection of cables, and the integrity of the earthing arrangement.
  • Testing — continuity of protective conductors, insulation resistance, polarity, earth fault loop impedance, RCD operation (including Type-A/Type-B characteristic, where fitted), AFDD functional test where installed, and PEN-fault simulation for charge points using integral open-PEN devices.
  • Functional commissioning — charge cycle test with a vehicle or test load, lock-mechanism test, app/back-office pairing, smart-charging schedule verification.
  • Documentation — issue an EIC for the addition, issue the manufacturer’s commissioning sheet, and provide the customer handover pack (user guide, RCD test instructions, supplier contact details, MCS certificate if registered).

How to plan and execute an EV charger install

A six-stage sequence from site survey to handover, with the paperwork mapped to each stage.

1

Site survey and design

Carry out a site survey covering supply arrangement (TN-S, TN-C-S/PME, TN-C-S/PNB, TT), prospective fault current, earth fault loop impedance, maximum demand, available consumer-unit ways, the proposed location of the charge point, and the cable route. Confirm DNO notification path (G98 connect-and-notify, or G99 pre-notification). Record the design decisions — earthing arrangement selected, RCD type, AFDD inclusion or documented exemption under 722.421.1.7.201 — in the design file.

2

Generate the RAMS

Build the Risk Assessment and Method Statement before mobilising to site. List the hazards in this guide, assign control measures, name competent persons, and append the site-specific information (parking, access, isolation point, customer contact). Elec-Mate’s [RAMS Generator](/tools/rams-generator) builds the document from the survey inputs in under a minute and outputs a customer-ready PDF.

3

Notify the DNO and the customer

For G99 installations, submit the application and wait for written approval before mobilising. For G98 installations, prepare the connect-and-notify form for submission within 28 days of energisation. Issue the RAMS to the customer at least 24 hours before work starts, with the proposed isolation window clearly stated.

4

Safe isolation and first fix

Follow the safe-isolation method statement: identify the circuit, isolate at the main switch, lock-off and tag, prove dead with a GS38-compliant tester against a known live source before and after. Run the sub-main, drill external penetrations, mount the charge point enclosure, and pull cables back to the consumer unit or sub-board. Restore supply only after all live parts are enclosed.

5

Commission and test

Energise the new circuit. Carry out the BS 7671 Chapter 64 inspection, the dead tests (continuity, insulation resistance, polarity), the live tests (Zs, RCD operation, AFDD where fitted, PEN-fault simulation where the unit has an integral open-PEN device), and the manufacturer’s functional commissioning sequence. Capture the readings as you go.

6

Certify and hand over

Issue the [EV Charger Certificate](/ev-charger-certificate) (Electrical Installation Certificate for the addition, with the EV-specific commissioning record), provide the customer handover pack, and submit Part P notification (or self-certify via a registered scheme). Submit the DNO G98 notification within 28 days. File the RAMS, the test results and the certificate against the job in your back-office system.
