1. Scope of works

2. Sequence of works

Method statement, safe system of work

Arrive at the property, introduce ourselves to the householder, explain the works, the expected duration and the period the power will be off, and confirm welfare arrangements.
Carry out a survey: confirm the supply earthing arrangement (TN-C-S/PME, TN-S or TT), the main earthing and bonding, the consumer unit spare ways, and the proposed cable route and charge point position.
Confirm the selected charge point and protective arrangement provide the required PEN-fault protection and RCD/DC-fault detection for the installation to BS 7671 Section 722.
Agree the charge point mounting height and cable route with the householder and check the route for buried or concealed services.
Establish a tidy work area, lay dust sheets internally around the consumer unit and keep access routes clear for the occupants.
Follow the safe isolation procedure before working on the consumer unit: prove the voltage indicator on a known source or proving unit, confirm the point is live, isolate the main switch, lock off and apply a 'Do Not Operate' sign, then prove dead at the point of work, and re-prove the indicator afterwards.
Before drilling the external wall, scan the wall internally and externally with a cable/pipe detector to locate buried electrical cables, water and gas services, and adjust the route to avoid them.
Drill through the external wall at the confirmed position to the required depth only, and install the external gland/sleeve to weatherproof the penetration.
Run and clip the new dedicated circuit cable from the consumer unit along the agreed route in suitable containment, maintaining separation from other services.
Where the unit is mounted high on the wall, use an inspected step ladder on firm level ground, maintaining three points of contact and not overreaching.
Mechanically fix the charge point to the external wall at the agreed height, ensuring it is level and secure, and gland the cable into the unit to maintain its IP rating.
Terminate the circuit at the charge point with correct polarity and torque, and install the correct protective device (RCBO with the required RCD type) at the consumer unit; do not re-energise yet.
Where the charge point does not integrate PEN-fault protection, install and connect the required earthing arrangement (for example an earth electrode for an O-PEN/TT solution) and verify its resistance.
Carry out dead tests: continuity of protective conductors (R1+R2), continuity of ring/radial, insulation resistance and polarity on the new circuit.
Remove the lock-off, re-energise the supply under controlled conditions with all personnel clear, and carry out live tests: earth fault loop impedance (Zs), RCD trip times and, where fitted, the PEN-fault/O-PEN detection function test.
Commission the charge point per the manufacturer's procedure, set it to the correct mode/current and confirm correct operation with a test load or approved test adapter.
Label the new circuit and protective device, update the consumer unit schedule, and complete the Electrical Installation Certificate and any DNO/manufacturer notification.
Demonstrate the charge point to the householder, explain safe use, the RCD test button and what to do in a fault, and provide the certification and manufacturer documentation.
Clean and tidy the work area, remove all waste and tools, confirm the installation is safe and the property is left secure, and confirm completion with the householder.

3. Risk assessment

HSE 5-STEP · MHSWR 1999 REG 3 · HIERARCHY OF CONTROL

Risk assessment: hazards, who may be harmed, controls and residual risk
Hazard	Who / how	Existing controls	L×S	Additional controls	Residual
Electric shock or electrocution from working on the live consumer unit and supply.	Operative, householder. Can result in severe injury or fatality.	Competent electrician (18th Edition, C&G 2921, ECS card). Insulated tools. Awareness of safe working practices.	3×5=15	Follow the full safe isolation procedure to GS38: prove the voltage indicator on a proving unit, confirm live, isolate, lock off and sign, prove dead at the point of work, then re-prove the indicator. Work on the installation dead wherever possible. Use a GS38-compliant voltage indicator with finger guards and fused leads. Obtain an electrical isolation permit. Keep the householder and others clear of the consumer unit while it is open, and only re-energise when everyone is clear.	Low
PEN (open combined neutral-earth) conductor fault on a TN-C-S (PME) supply making exposed metalwork and the vehicle live.	Operative during testing, householder and vehicle users during use. Electric shock, serious injury or fatality.	Awareness that a PME supply can present a dangerous voltage on the earth under an open-PEN fault. BS 7671 Section 722 requirements understood.	2×5=10	Design the installation to protect against an open-PEN fault as required by BS 7671:2018 Section 722: use a charge point with integral O-PEN/PEN-fault detection that disconnects the supply, or install a suitable earthing arrangement (for example a dedicated earth electrode/TT solution) where an integral device is not provided. Verify the protective measure by functional test at commissioning and record the earth electrode resistance where installed. Do not connect the charge point earth to the PME earth where prohibited by the design. Follow the IET Code of Practice for EV Charging Equipment Installation.	Low
Striking buried or concealed services (electric cables, water, gas) when drilling through the external wall.	Operative, householder, property. Electric shock, gas leak, flooding, fire or structural damage.	Competent operative aware of likely service routes. Visual assessment of the wall internally and externally.	2×4=8	Scan the drilling position with a cable/pipe detector from both faces of the wall before drilling and adjust the route to avoid services. Avoid drilling directly above or below sockets, switches, boilers and taps where services are likely to run. Drill only to the required depth using a controlled feed. Where any doubt remains about a concealed service, stop and investigate before continuing.	Low
Fire from an incorrectly rated protective device, poor termination or overloaded existing supply.	Householder, operative, property. Serious injury, fatality and property damage.	Competent electrician. Protective devices selected to BS 7671. Existing installation assessed for spare capacity.	2×4=8	Assess the maximum demand and confirm the supply and consumer unit have adequate capacity for a new 7kW circuit before installation; refer to the DNO where the supply may be insufficient. Select and install the correct cable size and the correct protective device (RCBO with the required RCD/DC-fault type) for the charge point. Terminate to the correct torque and confirm by full dead and live testing. Keep the charge point clear of stored flammable materials and confirm its IP rating is maintained.	Low
Fall from a step ladder when mounting a high external charge point or running cable at height.	Operative. Falls can cause fractures, head injuries or worse.	Suitable step ladder, inspected before use. Working at height awareness.	2×3=6	Mount the charge point at a practical low working height where the design allows, reducing work at height. Use only an inspected, class-rated step ladder set on firm, level ground for short-duration work. Maintain three points of contact, do not overreach, and keep the base area clear. Have materials and tools passed up or in a tool belt rather than carried by hand. Do not use a ladder in high wind or wet, slippery conditions.	Low
Working in an occupied home: disruption to occupants, trip hazards, and property damage.	Householder (distress, injury, loss of power), operative (slips/trips), property.	Experienced operative. Good communication with householder. Tidy working.	3×2=6	Hold a pre-start discussion to explain the works and the power-off period and agree timings that suit the household. Use dust sheets and keep the work area and access routes clear and tidy. Do not leave tools or the open consumer unit unattended within reach of children. Restore power promptly and confirm essential circuits before leaving. Leave the property clean and secure and brief the householder on the completed work.	Low
Adverse weather affecting external work: rain and cold making surfaces slippery and compromising electrical safety outdoors.	Operative. Slips, electric shock from moisture ingress, and defective terminations.	Assessment of conditions before external work. Charge point rated for external use (IP rated).	2×3=6	Do not carry out external electrical connections in wet conditions; postpone or protect the work area from rain with temporary cover. Keep the charge point interior and terminations dry during installation and maintain the unit's IP rating with correct glands and seals. Do not use ladders on wet or icy surfaces. Ensure the external penetration is fully weatherproofed to prevent water tracking into the building or unit.	Low

4. Plant & equipment

Electrical hand tools (screwdrivers, pliers, strippers, torque screwdriver)
Multifunction electrical tester (calibrated)
GS38-compliant voltage indicator and proving unit (calibrated)
Lock-off kit and 'Do Not Operate' tags
Cable/pipe detector (CAT-type or wall scanner)
SDS drill and masonry bits
Earth electrode and driving tool (where a TT/O-PEN earthing solution is used)
Step ladder (EN 131 compliant, inspected)
Dust sheets and cleaning materials

5. Materials / COSHH

No significant COSHH hazards. Drilling masonry generates dust; keep it to a minimum, use a dust sheet and vacuum, and wear a dust mask and eye protection when drilling. Any sealant or gland compound used to weatherproof the wall penetration is used per its Safety Data Sheet, avoiding skin and eye contact. Electrical waste (cable offcuts, old fixings, packaging) is segregated and removed from site for correct disposal or recycling. Safety Data Sheets for any product introduced are consulted before use.

6. PPE

Safety footwear (steel toe caps)
Safety glasses/goggles (drilling and testing)
Insulated gloves (when proving dead or working near live parts)
Flame-retardant clothing (for live testing at the consumer unit)
Dust mask (P2 or higher, when drilling masonry)
Gloves (handling and cable work)

7. Competence & training

The operative is a qualified electrician to the 18th Edition IET Wiring Regulations (BS 7671), holds NVQ Level 3 in Electrical Installation, City & Guilds 2921 for electric vehicle charging equipment installation, and a valid ECS card. S. Nkomo (Author) is competent in safe isolation to GS38 and in the requirements of BS 7671 Section 722 and the IET Code of Practice for EV Charging Equipment Installation. Working at height and manual handling awareness training are held.

8. Permits

Electrical isolation permit (issued and signed before the isolation procedure begins).
DNO notification/consent where required for the earthing arrangement or supply capacity on a PME supply.

9. Access & egress

Access is via the domestic driveway to the external wall and internally to the consumer unit. Cable routes and access to the working areas are kept clear of obstructions. The householder's normal access into and out of the property, and emergency egress, are maintained throughout the works. The step ladder is positioned so as not to obstruct escape routes.

10. Welfare

Welfare facilities within the home (toilet and hand-washing) are used by arrangement with the householder where offered and suitable; otherwise the nearest agreed facility is used. The operative carries drinking water. Breaks are taken away from the immediate work area to minimise disruption to the occupants.

11. First aid

A stocked first aid kit is carried in the company vehicle and its location is known to the operative. In the event of serious injury, call 999 immediately and give the site address. For electric shock, do not touch the casualty until the supply is isolated and it is safe to approach, then administer first aid and call for help. Burns are cooled and covered. Where the operative works alone, a check-in arrangement with the office is in place.

12. Emergency procedures

In the event of electric shock, isolate the supply at the main switch before touching the casualty, then call 999 and administer first aid. In the event of fire, evacuate the property with the householder, call 999, and do not tackle an electrical fire with water. If a gas or water service is struck, isolate the supply where safe, ventilate for gas, evacuate and call the relevant emergency line (gas emergencies 0800 111 999) and the householder. Report all incidents to the company and, where reportable, under RIDDOR.

13. Environmental

Waste cable, packaging and fixings are segregated and removed from site for recycling or correct disposal; nothing is left on the property. Drilling dust is contained and cleaned up rather than washed into drains. Vehicle movements are kept to the single visit. Noise from drilling is kept brief and considerate given the occupied home and neighbours. No hazardous waste is expected beyond minor sealant residues, which are disposed of per the Safety Data Sheet.
