Electrical faults can range from a minor inconvenience to a genuine safety hazard. Whether you have a circuit that keeps tripping, a partial power failure, flickering lights, a burning smell from a socket, or no obvious cause at all — ATO Solutions will diagnose the problem accurately and advise you on the safest way to resolve it.
We are a NICEIC-accredited electrical contractor based in Wimbledon, with over 17 years of experience identifying and repairing electrical faults in domestic and commercial properties across South West London. We do not guess — we use the right diagnostic equipment to find the root cause, not just the symptom.
Common Electrical Faults We Diagnose and Repair
Electrical problems are not always straightforward. What appears to be a single fault often has an underlying cause that, if left unaddressed, can lead to further failures or create a safety risk. We regularly attend call-outs for:
Tripping circuit breakers – a breaker that trips repeatedly is a sign of an overloaded circuit, a faulty appliance, or a wiring fault. We identify which circuit is affected and establish the cause before recommending a fix.
Partial power loss – if you have lost power to part of your property but not all of it, this typically points to a blown fuse, a tripped breaker, or a fault on a specific circuit. We trace the fault and restore the circuit safely.
Flickering or dimming lights – can indicate a loose connection, a failing fitting, an overloaded circuit, or a more significant wiring issue. We test the circuit and all connections to identify the cause.
Dead sockets or switches — a socket or switch that has stopped working may have a loose or burned connection behind it, or may be on a circuit with a fault elsewhere.
RCD tripping — a residual current device (RCD) that trips frequently is doing its job, but the underlying cause needs to be found and resolved. We identify the appliance or wiring fault that is triggering it.
Burning smells or scorch marks — these should always be treated as urgent. Scorch marks around sockets, switches, or the consumer unit indicate overheating that can lead to electrical fire. Contact us immediately.
Complete power failure — if you have lost all power to your property, we will establish whether the fault lies with the consumer unit, your supply, or a specific installation issue.
Domestic Fault Finding
For homeowners and tenants, an unexplained electrical fault is stressful, particularly when it is not immediately clear whether the problem is with your own installation or with the supply. We carry out a systematic diagnostic inspection of your consumer unit, circuits, and wiring to pinpoint the fault, and we explain clearly what we have found and what your options are before any repair work begins.
We also carry out fault-finding as part of a broader refurbishment or rewire — if you are updating your home and want to assess the condition of your existing installation before work starts, we can do so as a first step.
Commercial Fault Finding
An electrical fault in a commercial premises — an office, restaurant, retail unit, or other business — can disrupt operations and, depending on the nature of the fault, may create a legal obligation to take the premises out of use until the issue is resolved. We understand the urgency of this and work efficiently to minimise downtime. We are also happy to attend outside normal business hours, where that is more practical.

Frequently Asked Questions
How quickly can you attend an electrical fault?
For emergency call-outs, contact us on 0800 050 2424 and we will advise on current availability. For non-urgent fault finding, we aim to offer prompt appointments across South West London.
Is it safe to stay in my property if I have an electrical fault?
It depends on the nature of the fault. A single dead socket is unlikely to pose an immediate risk, but scorch marks, burning smells, sparking, or repeated RCD trips should be treated as urgent, and you should avoid using the affected circuits until they have been inspected. If in any doubt, call us.
Will you repair the fault on the same visit?
In many cases, yes — particularly for straightforward faults such as a failed connection, a faulty socket, or a tripped circuit with an identifiable cause. More complex faults, or those requiring parts, may need a follow-up visit. We will always give you a clear picture of what is involved before we start.
Can an electrical fault cause a fire?
Yes. Loose connections, overloaded circuits, damaged wiring, and failing components can all generate heat that, over time, can lead to an electrical fire. This is why faults should always be properly diagnosed rather than managed with temporary workarounds such as repeatedly resetting a tripped breaker.
Do I need an EICR if I have had a fault repaired?
Not automatically, but if the fault has revealed an underlying issue with your installation — particularly in an older property — it is worth considering a full EICR to establish the overall condition of your wiring. We can advise on this after the fault-finding visit. See our EICR page for more.
What areas do you cover?
