EV Charger Maintenance and Safety Compliance: What Manchester Property Owners Must Know
Installing an EV charger is only the beginning. Like any electrical installation, chargepoints require regular maintenance, periodic inspection and ongoing compliance checks to remain safe and legal. Yet many property owners across Manchester treat their EV chargers as fit-and-forget devices, only calling an electrician when something breaks.
This approach creates real risks. A faulty chargepoint can cause electric shock, fire or damage to the vehicle's battery management system. For commercial property owners and landlords, there are additional liability and insurance implications if a chargepoint causes injury or damage and cannot be shown to have been properly maintained.
This guide explains the maintenance requirements for EV chargers, the compliance framework that applies, and what Manchester property owners should include in their chargepoint maintenance programme.
Why EV Charger Maintenance Matters
An EV charger delivers significant electrical current — a standard 7kW unit draws 32 amps continuously, while a 22kW three-phase charger draws up to 32 amps per phase. Rapid chargers on commercial sites deliver 50kW or more. These are not small loads, and the components that manage them — contactors, relays, cable connections, RCDs and communication modules — experience wear over time.
Common failure modes include degraded cable insulation from UV exposure and physical wear, loose terminal connections that create heat and potential fire risk, failed or degraded RCD protection that leaves users unprotected against electric shock, software faults that prevent proper communication with the vehicle, water ingress into outdoor-mounted units, and mechanical damage to charging cables and connectors from regular use.
Most of these issues develop gradually. A chargepoint may continue to function with a degraded safety device or a loose connection for months before a visible fault occurs. Regular inspection catches these problems before they become dangerous.
The IET Code of Practice for EV Charging
The Institution of Engineering and Technology publishes the Code of Practice for Electric Vehicle Charging Equipment Installation, now in its fifth edition. This document is the primary technical standard for EV charger installation and maintenance in the UK and supplements the general requirements of BS 7671, the IET Wiring Regulations.
The Code of Practice covers design and selection of charging equipment, installation requirements including cable sizing, protection and earthing, commissioning and verification testing, and ongoing inspection and maintenance.
For maintenance specifically, the Code of Practice recommends that EV charging installations should be included within the scope of periodic inspection and testing carried out under BS 7671. This means that when a building's EICR is carried out, the EV charging circuits should be inspected and tested as part of the report.
The Code also recommends that chargepoint operators and building owners establish a maintenance regime that includes regular visual inspections, functional testing of safety devices, and periodic electrical testing of the charging circuits.
Recommended Maintenance Schedule
There is no single legally mandated maintenance frequency for EV chargers, but industry best practice and manufacturer requirements provide clear guidance. The following schedule represents the minimum recommended maintenance for most installations.
Monthly visual checks should be carried out by the building owner or a responsible person. These involve checking the chargepoint housing for visible damage, cracks or water ingress, inspecting charging cables for cuts, abrasion or exposed conductors, verifying that indicator lights and displays function correctly, checking cable connectors for damage or contamination, and confirming that the chargepoint is securely mounted.
Six-monthly functional tests should verify that the RCD protecting the charging circuit trips correctly when tested, that the chargepoint initiates and terminates charging sessions properly, that any payment or access control systems function correctly, and that network connectivity and remote monitoring are operational for smart chargers.
Annual professional inspection should be carried out by a qualified electrician. This inspection includes electrical testing of the charging circuit including insulation resistance, earth fault loop impedance and RCD trip times, thermal imaging of connections under load to identify hotspots, verification that all protective devices are correctly rated and functional, inspection of cable containment and mechanical fixings, firmware updates where applicable, and a formal inspection report documenting findings and any remedial actions.
For commercial installations with high usage — such as public car parks, fleet depots or workplace charging — more frequent professional inspections may be appropriate. Chargepoints subject to heavy daily use experience greater mechanical wear and should be inspected every six months.
EICR and EV Charger Compliance
When an Electrical Installation Condition Report is carried out on a property with EV charging, the charging circuits should be included in the scope of the inspection. This means the EICR inspector will test the dedicated EV charging circuit, verify the protective devices including the dedicated RCD or RCBO for the charging circuit, check earthing arrangements including any PME earthing considerations, inspect the cable route from the distribution board to the chargepoint, and confirm that the installation complies with current BS 7671 requirements.
If the EV charging installation predates the current edition of BS 7671, the inspector may note observations or recommendations for upgrade. Common issues found during EICR inspections of EV charging circuits include incorrect RCD type — Type A RCDs are insufficient for EV charging and Type B or Type EV RCDs are required — inadequate cable sizing for the installed chargepoint rating, missing or incorrect protective earth arrangements particularly on PME supplies, and absence of isolation switching.

Common EV Charger Faults and How to Identify Them
Understanding the symptoms of common chargepoint faults helps property owners identify problems early, before they create safety hazards.
Intermittent charging failures — the charger starts a session then stops unexpectedly or fails to start at all. This often indicates a communication fault between the charger and the vehicle, a failing contactor relay, or an RCD tripping under load due to a developing earth fault.
Slow charging speeds — the vehicle charges at a significantly lower rate than the chargepoint's rated output. This can indicate cable degradation reducing current-carrying capacity, a load management system limiting output due to building demand, or a chargepoint hardware fault reducing maximum output.
Overheating — the chargepoint housing or charging cable feels excessively warm during operation. This is a serious safety concern that often indicates loose electrical connections generating resistive heat, an overloaded circuit, or inadequate ventilation around the chargepoint.
Error codes and warning lights — most modern chargepoints display error codes when faults are detected. These should never be ignored. Common codes relate to earth fault detection, communication failures, overcurrent protection trips and internal temperature limits.
Physical damage — cracked housings, damaged cable sheathing, bent connectors or missing covers all compromise the IP rating of the installation and allow water ingress. Outdoor chargepoints in Manchester are particularly susceptible to weather damage and should be checked regularly.
Any of these symptoms warrants investigation by a qualified electrician. Continuing to use a chargepoint with a known or suspected fault creates liability for the property owner.
Liability and Insurance Considerations
For commercial property owners, landlords and building managers, EV charger maintenance is directly linked to liability and insurance coverage.
Under the Electricity at Work Regulations 1989, the duty holder — typically the building owner or employer — must ensure that electrical systems are maintained to prevent danger. An EV charger that causes injury or damage due to lack of maintenance could result in prosecution under these regulations.
Insurance providers increasingly ask about EV charging installations when underwriting commercial properties. A policy may require evidence that chargepoints are maintained in accordance with manufacturer recommendations and the IET Code of Practice. Without this evidence, a claim arising from a chargepoint incident could be disputed or denied.
The simplest way to demonstrate compliance is to maintain a documented maintenance programme with records of all inspections, tests and remedial work. This documentation should be kept alongside the property's EICR records and made available to insurers on request.
Manufacturer Warranty and Maintenance Requirements
Most EV chargepoint manufacturers stipulate maintenance requirements as a condition of their product warranty. Failing to carry out recommended maintenance can void the warranty, leaving the property owner responsible for replacement costs if the unit fails.
Typical manufacturer warranty conditions require installation by an accredited installer, annual inspection by a qualified electrician, use of genuine replacement parts, firmware updates applied within specified timeframes, and no unauthorised modifications to the unit.
Before purchasing a chargepoint, check the manufacturer's warranty terms and factor ongoing maintenance costs into the total cost of ownership. A cheaper unit with onerous maintenance requirements or a short warranty may cost more over its lifetime than a premium unit with comprehensive warranty coverage.
Building a Maintenance Programme for Your Manchester Property
A practical EV charger maintenance programme should include a schedule of monthly visual checks carried out by building staff, six-monthly functional tests documented in a maintenance log, annual professional inspections by a qualified electrician, a process for reporting and responding to faults, records of all maintenance activities, and a budget for ongoing maintenance and eventual replacement.
For commercial properties with multiple chargepoints, a maintenance contract with a specialist electrical contractor is the most efficient approach. This provides scheduled inspections, priority response for faults, and documented compliance records.
