Maintenance is not the same as repair
A repair happens after something has failed. Maintenance is what stops you needing one — and on a commercial site it is also what keeps you compliant and your chargers earning.
The two most expensive words in EV charging are "out of order". A charge point that quietly stopped working three weeks ago has cost a car park three weeks of revenue, and a driver who found it dead is unlikely to come back.
If your charger has already failed, our charge point repair service is the page you want. If you would rather it did not, read on.
What a maintenance visit actually covers
A service visit on an AC charge point normally includes:
- Visual inspection — enclosure, mountings, cable entry, seals and weatherproofing
- Socket and connector check — the single most common failure point. Contacts are inspected for discolouration, pitting, carbon tracking and heat damage
- Cable and strain relief — abrasion, crushing, exposed conductors on tethered units
- Electrical testing — earth continuity, insulation resistance, RCD trip times and PEN fault protection where fitted
- Torque check on terminations, which loosen with thermal cycling
- Functional charge test under real load, not just a power-on light
- Firmware and configuration where the unit supports it
- Back-office and connectivity check on networked units
- Cleaning of the enclosure and the socket face
- Written report with anything found and anything replaced
On DC rapid units the work is larger: cooling, filters, contactors, isolation monitoring and the power modules themselves.
How often should an EV charger be serviced?
There is no single legal interval for every installation, so treat these as sensible practice rather than regulation:
- Home charge points — a check every couple of years is usually enough, and worth doing sooner if the unit lives in an exposed position or the cable is left on the ground
- Workplace and small commercial sites — annually, aligned with your fixed wiring inspection where possible
- Public and heavily used sites — at least annually, and more often for DC rapids and anything taking payment
Between visits, the useful checks take about a minute: look inside the socket with a torch for discolouration, feel whether the plug is unusually hot after a charge, and stop using the unit if it trips its RCD repeatedly. There are photographs of what a neglected socket looks like in our guide to home EV charger repair.
Commercial sites: uptime is now a legal question
If you operate public charge points, reliability is not only commercial. The Public Charge Point Regulations 2023 introduced duties for public charging in Great Britain, including a reliability standard for rapid charging networks and a requirement to offer a 24/7 helpline for drivers.
In practice that means a site owner needs to be able to show that faults are found and fixed, not discovered by a driver on a Sunday. A maintenance arrangement is the straightforward way to do that.
We work with car parks, hotels, offices, fleets and facilities managers. Depending on the site we can cover:
- Scheduled inspections across a whole estate, in one visit where the sites are close together
- Reactive attendance when a unit reports a fault
- Consumable and wear-part replacement — sockets, cables, holsters, seals
- A written condition report per charge point, which is what auditors and insurers ask for

Why a manufacturer services differently
Most maintenance providers are installers. When a board or a socket fails, they order a part from the brand — if that brand still supplies one — and come back another day.
We design and build charge points ourselves. That changes three things:
- We hold parts. Sockets, connectors, holsters, contactors and control components sit on our shelves, so a fault found on a service visit can often be corrected on the same visit
- We work at component level. A failed board is a board to be diagnosed, not a sealed unit to be swapped for a new charger
- We service any make. Most of the units we attend were installed by somebody else, and a good number are brands we do not manufacture
Where the station allows it, we can also commit to a fixed all-in repair price rather than an open-ended bill — the details and the exceptions are set out in our fixed-price repair guide.
Arrange servicing
Tell us what you have — the make, roughly how old it is, and how many units on the site — and we will tell you what servicing it needs and what it costs. If you already know something is wrong, a photograph of the socket face saves everyone a visit.
