When your home EV charger stops working, every day without it means falling back on expensive public charging, wasted time, and unnecessary frustration. Chelsea Electrical provide fast, expert EV charger fault finding and repair across Chelsea and South West London — with same day attendance available across our entire service area and a 12 month minimum guarantee on every repair we carry out.
Our OZEV registered electricians diagnose and repair all major brands of home EV charger — including chargers we did not originally install. Whether your charger has completely stopped working, is displaying an error code, charging slower than expected, or is causing your fuse board to trip — we identify the fault, explain it clearly, and fix it as quickly as possible.
Every repair is carried out by a time-served electrician with a minimum of 10 years hands-on experience — led by our lead engineer with 26 years in the trade. We do not guess, we do not replace parts unnecessarily, and we do not leave until your charger is working correctly and you are completely satisfied.
Every EV charger fault has a cause — and our OZEV registered electricians have diagnosed and repaired every one of them across Chelsea and South West London. For independent guidance on EV charger safety, Electrical Safety First provides comprehensive advice on safe home EV charging. Here are the most common EV charger faults we attend:
If your EV charger has no power and is completely unresponsive, the cause is usually a tripped circuit breaker, a failed RCD, a blown fuse, or a fault within the charger unit itself. Our electrician will work through a systematic diagnostic process to identify the exact cause and restore power to your charger as quickly as possible.
An EV charger that repeatedly trips your consumer unit is one of the most common faults we attend across Chelsea and South West London. It is usually caused by an earth fault within the charger, a deteriorating RCD on the dedicated EV circuit, or a charger that is drawing more current than the circuit can safely supply. Left unresolved this fault can cause wider electrical problems in your home — call us today for same day attendance.
If your EV charger is working but charging significantly slower than usual, the cause is typically a load balancing configuration issue, a smart tariff scheduling conflict, a WiFi connectivity problem affecting smart charging controls, or a hardware fault within the charging unit. Our electricians diagnose slow charging faults quickly and accurately — restoring your charger to full speed on the same visit in the majority of cases.
Every major EV charger brand uses a different error code system — and interpreting those codes correctly requires brand-specific knowledge and diagnostic equipment. Our OZEV registered electricians are trained across all major brands including Ohme, Hypervolt, Zappi, Andersen, Wallbox, Tesla, Easee One and Evec — and can interpret and resolve every error code these brands display.
If your smart EV charger has lost its connection to the app — or the app is no longer responding to commands — the cause is usually a WiFi connectivity issue, a firmware update failure, or a fault with the charger's communication module. Our electricians diagnose and resolve smart charger connectivity faults across all major brands, restoring full app control on the same visit where possible.
A charging cable that will not release from your vehicle or from the charger unit is usually caused by a locking mechanism fault, a power failure during charging, or a software issue preventing the cable release command from being sent. Our electricians carry the specialist tools required to safely release stuck cables without damaging your vehicle or your charger.
Flashing lights or warning indicators on your EV charger are the unit's way of telling you something is wrong — but the meaning varies significantly between brands. Our OZEV registered electricians interpret warning indicators across all major brands and use brand-specific diagnostic equipment to identify the underlying fault quickly and accurately.
If your EV charger has been physically damaged — whether from accidental impact, weather exposure, or vandalism — our electricians will assess whether the unit can be safely repaired or whether a replacement installation is required. We never recommend a replacement when a repair is safe and sufficient — but we will always give you an honest assessment.
When our OZEV registered electrician arrives at your Chelsea property, we do not guess — we follow a structured, systematic diagnostic process that identifies the root cause of your EV charger fault accurately and efficiently. Here is exactly what happens:
Before touching the charger, our electrician carries out a visual inspection of the unit, the cable, the mounting position, and the surrounding installation — looking for obvious signs of physical damage, water ingress, overheating, or loose connections. We also check your consumer unit for any tripped breakers or RCD faults on the dedicated EV charger circuit. In many cases this initial assessment alone identifies the fault.
Once the visual inspection is complete, we carry out a series of electrical tests on the dedicated EV charger circuit — checking earth continuity, insulation resistance, polarity, and earth fault loop impedance. This confirms whether the fault lies within the charger unit itself, the dedicated circuit, or the consumer unit — and determines the most efficient repair pathway.
Every major EV charger brand has its own diagnostic interface, error code system, and fault logging capability. Our OZEV registered electricians use brand-specific diagnostic tools and software to interrogate your charger's fault log, interpret error codes accurately, and identify faults that cannot be found through visual inspection or electrical testing alone. This is the stage that separates a genuine EV charger specialist from a general electrician attempting a repair.
Once the fault has been identified, we explain exactly what has gone wrong, what repair is required, and provide a clear fixed price quote before any repair work begins. There are no surprises, no unnecessary parts replacements, and no work carried out without your prior agreement.
Once you have agreed the repair, our electrician carries out the work using genuine manufacturer-approved parts where required — ensuring your charger performs to its original specification after the repair. Once the repair is complete, we carry out a full post-repair test to confirm the fault has been resolved and your charger is operating correctly and safely.
In some cases — particularly where a charger has suffered significant internal damage or where the cost of repair exceeds the value of the unit — a replacement installation is the more practical and cost-effective solution. Our electrician will always give you an honest assessment of whether repair or replacement is the right recommendation for your specific situation. If a replacement is required, find out more about our EV charger installation service in Chelsea — with same day installation available from £798 fully installed and certified.

One of the most common questions we are asked when attending an EV charger fault in Chelsea is whether the unit can be repaired or whether a full replacement is more appropriate. The honest answer depends on the nature of the fault, the age of the charger, and the cost of the repair relative to the cost of a new installation.
In the majority of cases a targeted repair is the most cost-effective solution — particularly for chargers that are relatively new, have suffered a single component failure, or have developed a software or connectivity fault that can be resolved without replacing hardware. Our OZEV registered electricians will always recommend a repair when it is safe, practical, and cost-effective — we never recommend a replacement when a repair will do the job correctly.
In some cases a repair is not the most practical or cost-effective solution — and attempting to repair a charger that has suffered significant internal damage or is approaching the end of its serviceable life is neither safe nor cost-effective in the long term.
A replacement is typically the right solution when:
If our electrician determines that a replacement is the right recommendation, we will provide a clear fixed price quote for a new EV charger installation in Chelsea — with same day installation available from £798 fully installed and certified.
When your EV charger develops a fault, the electrician you choose needs to be more than just a general electrician with a screwdriver. EV charger diagnosis and repair requires brand-specific knowledge, specialist diagnostic equipment, and a genuine understanding of how smart charging systems, load balancing, and solar integration work. Getting it wrong does not just leave your charger broken — it can cause wider electrical problems in your home.

EV charger faults have a wide range of causes — from simple software or connectivity issues through to hardware component failures. The most common causes we encounter across Chelsea and South West London include tripped circuit breakers or RCD faults on the dedicated EV circuit, WiFi connectivity or app communication failures, firmware update failures, load balancing configuration issues, power surge damage, physical damage to the unit or cable, and internal component failures due to age or manufacturing defects.
If your EV charger is still within its manufacturer warranty period, we recommend contacting the manufacturer first — a warranty repair may be available at no cost. However if the manufacturer cannot attend quickly enough, or if the warranty has expired, our OZEV registered electricians can carry out a full diagnosis and repair using genuine parts where required. We will always advise you honestly on the most cost-effective route to getting your charger repaired.
A charger that is repeatedly tripping your consumer unit should be treated as a priority fault — not necessarily an emergency, but something that requires prompt attention. Repeated tripping can indicate an earth fault within the charger, a deteriorating RCD on the dedicated circuit, or a charger drawing more current than the circuit can safely supply. Call us on 02034 886942 and we will attend the same day. If your fuse board is tripping completely and affecting power to the rest of your home, contact our emergency electrician in Chelsea for immediate assistance.
The majority of EV charger repairs in Chelsea are completed on the same visit as the diagnosis — typically between 1 and 3 hours depending on the nature of the fault. Simple software, connectivity, or configuration faults are usually resolved within an hour. Hardware component replacements may take longer depending on parts availability. Our electrician will always give you a realistic timeframe once the fault has been diagnosed.
Yes — we assess all physically damaged EV chargers and advise on whether repair or replacement is the more appropriate solution. Where physical damage has affected internal components, a replacement may be more cost-effective than repair. Where the damage is superficial or limited to specific replaceable components, a repair is usually possible. Our electrician will give you an honest assessment on the same visit.
Our call-out pricing is fixed and transparent — daytime attendance (8am to 5pm) is £179 inc. VAT and evening attendance (5pm to 11pm) is £229 inc. VAT.

The cost of any further repair work is quoted separately once the fault has been identified and agreed before we begin.
