The UK’s EV charging market has grown rapidly since 2020. With more people switching to electric vehicles, thousands of home and workplace charge points have been installed across the country.
Now, many of those chargers are several years old – and owners are beginning to notice problems. Like any electrical system, EV chargers need ongoing care. Over time, they can develop faults, suffer from wear and tear, or run into software and safety issues.
At M J Wallace Limited, we’ve seen a sharp rise in service and support requests for aging EV chargers. Here are the most common issues we’re finding – and how our team can help you get your charger back to full working order.
1. Overheating Problems
One of the most talked-about examples has been the Easee charger, which faced overheating concerns in the UK and Europe. While not every unit was affected, it highlights an important point: EV chargers work hard, pushing high current for hours at a time. If components degrade, heat can build up -causing tripping, reduced performance, or even a safety risk.
What to do:
- Watch (and listen) for buzzing, hot casing, or frequent cut-outs.
- Make sure your charger is on a solid wall with good ventilation.
- If you suspect overheating, stop using it and contact M J Wallace Limited for a professional inspection and safety test.
2. Connectivity and Software Failures
Modern chargers depend on apps and cloud services. As software evolves, some older models lose compatibility or develop bugs – especially if the manufacturer has stopped releasing updates.
What to do:
- Try a reboot and check for firmware updates.
- If the app no longer works or your charger keeps dropping offline, get in touch with M J Wallace Limited. We work with multiple charger brands and can diagnose software and connection faults quickly.
- If the unit is beyond repair, we’ll recommend a suitable replacement that’s compatible with your EV and home setup.
3. Wear and Tear on Sockets and Cables
Every plug-in adds a little wear. Over time, sockets can loosen, contacts can burn, and cables can crack – especially on high-use or outdoor chargers.
What to do:
- Inspect your charger visually every few months.
- Stop using it if you notice discolouration, cracks, or movement in the socket.
- M J Wallace Limited can replace worn sockets, cables, or covers – often saving you the cost of a full charger replacement.
4. Warranty Confusion and Lack of Support
Many EV owners ask: “What happens if my charger breaks?”
Some manufacturers have reduced UK support or only honour warranties through the original installer – which can be frustrating if they’re no longer trading.
What to do:
- Check your paperwork for warranty length and terms (usually 2–3 years).
- If your original installer is unavailable, M J Wallace Limited can help. As NICEIC-approved contractors, we can test, advise, and often carry out the necessary repairs or replacements safely.
- We can also assist with warranty claims where manufacturer support is still active.
5. Outgrowing the Original Charger
EV technology has advanced quickly. A charger that seemed perfect in 2021 might now be limiting you. Common examples include:
- Slower charging speeds on newer EVs.
- Missing solar integration or smart tariff control features.
What to do:
- Our experts can assess whether a repair or upgrade makes more sense.
- We’ll recommend modern, future-ready chargers with solar and battery integration that could pay for themselves through energy savings.
EV chargers are essential for electric vehicle ownership, but they’re not “fit and forget.” Regular maintenance and timely upgrades keep them safe, efficient, and compliant with the latest standards.
