EV charger not working? Common problems we investigate

Most charger problems fall into a few patterns. Some are electrical faults in the installation. Others involve the vehicle, the charger's own software, its Wi-Fi connection or the charger hardware itself. A fault-finding visit helps work out which it is.

  • Charger not charging at all
  • Charger repeatedly tripping the breaker or RCD
  • Intermittent charging
  • Charging stopping unexpectedly
  • Charger showing an error or fault light
  • Damaged charging cables or connectors
  • Electrical supply or protective-device problems
  • Signs of overheating or water ingress
  • Load-management or CT-clamp issues

We can diagnose the electrical side of the problem. We can't promise to repair proprietary charger electronics or software, which sometimes needs the manufacturer.

EV charger fault finding – £100 inc VAT

If your charger has stopped working, keeps tripping or shows a fault, we'll come out and find out why.

The £100 call-out includes:

  • Local attendance
  • Up to one hour of fault investigation on site
  • Appropriate electrical checks
  • An assessment of the likely cause
  • Clear advice on next steps
  • Minor adjustments, where safe and appropriate

If the investigation needs more time, additional labour is £54 including VAT per hour, and we'll agree it with you first. Replacement parts and remedial work are quoted separately.

To be upfront: not every fault can be fixed on the first visit. Sometimes a part has to be ordered, or the fault lies with the charger manufacturer, the vehicle or the charger's software. You'll know where you stand before any extra work goes ahead.

Annual EV charger safety & maintenance check – £125 inc VAT

An optional preventative inspection for owners who want their charger and its supply checked over. Usually 60–90 minutes on site.

What the check covers (where applicable to your installation):

  • Visual inspection of the charger's condition
  • Charging cable, plug and socket (for tethered or socketed units)
  • Signs of heat damage, deterioration or water ingress
  • Charger mounting and enclosure condition
  • Relevant electrical supply and protective-device checks
  • Appropriate electrical testing based on your installation
  • Inspection of accessible terminations, where it is safe and permitted by the manufacturer's instructions
  • Charging operation checks, where possible
  • A written maintenance checklist with recommendations

Good to know:

  • We follow the manufacturer's instructions. Some chargers can't be opened without affecting the warranty, so we won't promise to open every unit.
  • We don't simply re-tighten connections on every visit. Terminals are only checked and tightened in line with the manufacturer's torque and inspection guidance.
  • This is not a full Electrical Installation Condition Report (EICR). If your property needs an EICR, we can quote for that separately.

Why consider EV charger maintenance?

A home charger can carry a high electrical load for hours at a time, often outdoors and in all weathers. Loose or poor connections, damaged cables, unsuitable protection and water getting in can all lead to electrical problems over time.

Domestic EV chargers don't routinely catch fire, and we don't want to alarm anyone. Problems are uncommon. But a periodic check is a sensible way to catch wear and damage early.

Annual servicing of a home charger isn't a legal requirement. How often a check makes sense depends on the manufacturer's guidance, the charger's age and condition, how much it's used and where it's installed. If you're unsure, ask us and we'll give you a straight answer.

Chargers we look at

We regularly see domestic chargers from Ohme, Hypervolt, Zappi / myenergi, Easee, Andersen, BG / Sync EV and ICS, among others.

We can assess installation and supply faults on many types of charger. Repairs to the charger's own hardware or software may need the manufacturer or their authorised support. CPB is not a manufacturer-authorised repair centre.

The £100 and £125 prices apply to local visits. Longer-distance attendance is quoted individually, so please include your postcode when you enquire.

EV charger repair FAQs

Why has my EV charger stopped working?

There are several possible causes: a tripped breaker or RCD, a fault with the supply or charger, a connectivity or software problem, or an issue with the vehicle or cable. Checking the app, error light and your consumer unit is a good start. If it keeps happening, book a fault-finding visit rather than repeatedly resetting it.

Why does my charger keep tripping?

Repeated tripping means something is detecting a fault or overload, which could be the charger, the cable or the supply. Please don't keep resetting it. Switch it off and contact us.

Can you repair a charger installed by another company?

Yes, we can investigate the electrical side of chargers installed by other companies. Hardware or software repairs on the charger itself may need the manufacturer.

How much does EV charger fault finding cost?

£100 including VAT. That covers local attendance and up to one hour on site. Extra time is £54 including VAT per hour, agreed with you first. Parts and remedial work are quoted separately.

Do home EV chargers need annual servicing?

Not as a legal requirement. The right interval depends on the manufacturer's guidance, condition, use and installation. Many owners like an annual check for peace of mind, especially for outdoor or older units.

What does the £125 maintenance check include?

A visual inspection, cable and connector checks, signs of heat or water damage, the mounting and enclosure, supply and protective-device checks, appropriate testing, accessible terminations where permitted by the manufacturer, charging operation checks and a written checklist. See the full list above.

Can you inspect an older EV charger?

Yes. Older units are often worth a check. We'll note anything that limits what we can inspect.

Will I receive a maintenance report?

Yes. You'll get a written maintenance checklist with our findings and recommendations. It is a record of what we inspected on the day, not an EICR and not a guarantee of future safe operation.

What happens if replacement parts are required?

We'll explain what's needed and quote the parts and labour separately. Nothing extra goes ahead without your agreement.

Can you repair all charger brands?

We can investigate the electrical installation behind most brands. Manufacturer-specific repairs may need authorised support, and we'll tell you honestly if that's the case.
