EV Charging Maintenance
Why EV Charger Maintenance Is Essential
EV chargers, like any electrical equipment, are subject to wear and tear over time. Factors such as weather exposure, heavy usage, software updates, and component ageing can lead to faults or reduced performance.
Here’s why keeping on top of EV charger maintenance is vital:
1. Safety
Chargers handle high voltages and frequent energy transfers. Faulty components or damaged wiring could create a fire risk or electrocution hazard. Preventive maintenance helps detect these risks before they become a problem.
2. Reliability
Nobody wants to plug in their vehicle only to find the charger isn’t working. For businesses, unreliable chargers can affect operations, employee satisfaction, or customer experience. For homeowners, it’s an inconvenience that can disrupt daily life. Regular maintenance ensures maximum reliability.
3. Compliance
EV charging equipment must comply with British standards and regulations, especially in commercial or public settings. Regular inspections help ensure continued compliance with the Electricity at Work Regulations 1989 and the latest IET Wiring Regulations (BS 7671).
4. Cost-efficiency
Minor issues can escalate into costly repairs if left unchecked. Regular servicing extends the lifespan of the unit and reduces long-term costs.
5. Performance
Software and firmware updates are common as charger manufacturers optimise performance and security. Maintenance ensures your system is up to date and running at full efficiency, providing you with the best user experience.
EV Charger Regulations In The UK
BS 7671 (IET Wiring Regulations)
The Electricity at Work Regulations 1989
OZEV Grant Conditions
If your charger was installed with help from the Office for Zero Emission Vehicles (OZEV), maintaining the unit may be part of the compliance requirements.
BS EN IEC 61851-1 and BS EN IEC 62196: International standards for the safety and performance of EV charging equipment.
PAS 1899:2022 (for public chargepoints)
A new British standard ensuring EV chargepoints are accessible for disabled users, requiring proper ongoing maintenance.
Non-compliance can result in invalid warranties, loss of insurance coverage, and — in the worst case — serious injury or liability. Don’t take that risk, allow Sygma’s experienced electricians handle the maintenance of your EV chargers.

How Often Should EV Chargers Be Serviced?
Frequency of servicing depends on usage and the environment. Here’s a general guideline:
Domestic EV Chargers
Every 12 months: For most homeowners, an annual check-up is sufficient.
Earlier if: You notice irregular behaviour (slow charging, unusual sounds, flickering lights), or if there has been recent electrical work on your property.
Commercial/Public EV Chargers
Every 6 to 12 months: Higher usage rates and public access require more frequent maintenance.
After any fault or outage: Immediate inspection following any failure, vandalism, or storm damage.
Quarterly visual inspections: Especially for outdoor or unsupervised locations.
Sygma offers custom maintenance plans for businesses, schools, retail parks, logistics hubs and fleet operators to ensure you stay compliant and fully operational.
