Why won't my EV charger start charging?

The most common causes are a tripped circuit breaker, a scheduled charging setting in the app, or a connectivity issue. Check the consumer unit first, then the app, and try restarting the charger.

Do I need an electrician or should I contact the charger manufacturer?

If the issue is with the electrical supply (tripping, no power to the unit), call an electrician. If the charger has power but shows a software error or will not authorise, contact the manufacturer first.

Is my EV charger covered under warranty?

Most home EV chargers come with a 3-year manufacturer warranty. Some brands offer extended warranties. Check your purchase documentation or contact the manufacturer.

Can I charge my car from a normal socket while the charger is broken?

Yes, as a temporary measure you can use the granny cable (3-pin charger) supplied with most EVs. This charges much more slowly (typically 6-8 miles of range per hour) but will keep you going until the wallbox is fixed.

What's happening?

A home EV charger (also called a wallbox or EVSE) that is not working means you cannot charge your electric vehicle at home. These units are typically hardwired to a dedicated circuit with their own MCB and RCD protection in the consumer unit. Common home charger brands in the UK include Ohme, Zappi, Pod Point, Easee, and Wallbox.

What usually causes it?

Tripped MCB or RCD on the dedicated EV charger circuit
Wi-Fi or connectivity issue preventing the charger from authorising a session
Scheduled charging active: charger is waiting for off-peak hours
Charger in fault state requiring a restart or reset
Power supply issue from the consumer unit to the charger
Internal charger fault: relay, contactor, or control board failure

Is it dangerous?

An EV charger that will not start is not dangerous. However, if the charger tripped the RCD when it last attempted to charge, do not keep resetting it: there may be an earth fault that needs investigation. If you notice a burning smell or heat from the charger or its cable, isolate the circuit immediately.

Can I fix it myself?

Check the consumer unit for a tripped MCB or RCD on the EV circuit: it is usually a 32A MCB. Check the charger app for error messages or scheduled charging settings. Restart the charger by switching the isolator off for 30 seconds and back on. Check your Wi-Fi: many chargers need connectivity to authorise charging. Try a different charging cable if you use a Type 2 tethered lead.

When should you call an electrician?

Call an electrician if the charger's circuit keeps tripping, if the charger shows a persistent fault light after resetting, if the charger has no power at all, or if the unit was recently installed and has never worked correctly.
