What Makes a Fault Hidden
Hidden faults are the ones that survive a normal look-around: nothing is scorched, nothing is warm, no fitting behaves badly in front of you. The damage is in the middle of a cable run, inside a joint buried under floorboards, behind plaster from a long-finished renovation, or in the tiny leakage path that moisture creates only under certain conditions. Some announce themselves rarely — a trip every few weeks — which is exactly why they get tolerated for years. They are also the faults that have usually been through someone else's guesswork first, with fittings swapped and nothing changed.
The Symptoms Worth Taking Seriously
An RCD that trips with no pattern you can identify; a tingle or shock from taps, radiators or appliance cases; sockets or lights dead despite everything looking normal; a trip that follows rain, damp weather or the washing machine; scorch marks with no explanation; a meter reading that seems high without a change in habits. Tingles from metalwork are the most important on the list — they mean current is finding a path through you, and that combination should never be lived with.
Why the Methodical Approach Wins
Hidden faults yield to instruments, not to intuition. The diagnostic starts with the history — when it happens, what changed before it started, which circuits are involved — because patterns that look random to a householder are often obvious in testing. Then it is measurement: insulation resistance to find leakage paths, continuity to find broken conductors, polarity and earth testing to find crossed connections, and dividing the installation into sections to corner the fault. Each test eliminates half of the remaining territory, which is how a fault buried anywhere in a house becomes a fault in one room, one circuit, one cable.
What the Visit Involves
Expect some practicality: access to the consumer unit, to fittings, and to lofts or under-floor routes where the cabling runs. We open the smallest areas the evidence requires and put them back properly. Where the fault turns out to be an appliance rather than the wiring — they do masquerade — we identify it with testing rather than by unplugging things at random, saving you from replacing a washing machine that was never guilty. You will know what has been found and what the repair costs before any repair work begins.
The Repair and the Clear-Up
Repairs follow the finding: replacing damaged cable runs, remaking buried joints properly in accessible positions, correcting crossed or swapped conductors, drying out and sealing points where moisture enters. We retest the full circuit afterwards and confirm the protective devices operate as designed — because the RCD that kept tripping has been guarding you all along, and it should trip cleanly when needed and stay quiet otherwise.
After the Diagnosis
We give you a plain summary of what the fault was, why it hid so well, and what in the rest of the installation is worth watching. If several circuits share the same vintage or the same builder, we will say so without any pressure to commit to more work than you came for.
When to Call Us
Book a diagnostic visit for any unexplained tripping, tingles from metalwork, unexplained dead points, faults that follow the weather, or anything previous attempts have failed to pin down. Tingles in particular should not wait — switch the power off at the consumer unit if it is safe to do so and call us promptly.
Book Your Fault Diagnosis Today
A hidden fault is only hidden until someone tests for it properly. Call or book online and we will bring the instruments, the method and the patience, find the fault you have been living around, and leave your installation behaving itself and proven safe.
How the price works
We charge a booking fee to hold your slot, then an hourly rate for the work itself. The fee changes with how soon you need us; the hourly rate changes with the slot you choose. You approve the price before we start, so there is no surprise on the invoice.

Nothing goes ahead until you agree the price. Labour is then charged per hour at your slot rate.
Some faults refuse to sit still: a breaker that trips every few days with nothing obviously plugged in, a slight tingle from a tap, a light that misbehaves only in the rain. These are hidden wiring faults — real, findable, and often harmless-looking on the surface. They need methodical testing rather than guesswork, and that is exactly what our diagnostic visits are for: we locate the fault, however deep it hides, and repair it with the smallest possible disturbance to your home.
What our customers say about our electrical service
4.6 out of 5 from 11 reviews
Does what it says on the tin
No complaints about the work itself — clear explanation, sensible advice, fair price. Booking online was easy enough once I found the right job page.
Job: Smoke Alarm Replacement
Fixed it, but took longer than expected
Work itself was fine and tidy. Communication beforehand was patchy — I did not get the confirmation message and had to ring to check the slot. Would still use again.
Job: Flickering Outdoor Lights
Turned up when they said
Third time we have used Maintenance Men, and the same experience each time: agreed price, proper explanation, job done in one visit. The hourly rate is fair for the standard of work.
Job: Appliance Causing Power Trip

Questions people ask about hidden wiring fault
Straight answers to the things customers ask most often before booking.
What does a hidden fault diagnosis cost?
You pay a booking fee when you book, then labour hourly at a rate set by how soon you need us. Hidden faults can take longer to corner than obvious ones, so diagnosis time varies — but the repair itself is always quoted in full and approved before any work starts.
I've swapped the socket and it still trips — what now?
That result is actually useful: it points away from the fitting and towards the cable or a junction along the route, which is where testing earns its keep. Keep swapping parts without measurements and you will spend more than a diagnosis costs, while the real fault stays exactly where it is.
What equipment do you use to find a hidden fault?
Insulation resistance testers, continuity and earth-loop testers, and a methodical plan of elimination. Measurements along the circuit tell us which sections are healthy and which are not, and dividing the installation step by step corners the fault. The equipment matters less than the sequence — that is what finds faults others have missed.
A tingle from my taps went away — should I still worry?
Yes. A tingle from metalwork means current found a path that included you, and the fact it is intermittent does not make it harmless — it makes it dependent on conditions you cannot see or control. Isolate at the consumer unit if it recurs and have the earthing and leakage tested promptly.
Can a faulty appliance cause wiring symptoms?
Regularly, and they are skilled impersonators. A washing machine with failing insulation can trip the same RCD as a damaged cable, and a fridge with a damp plug can mimic a roof leak. Testing separates the appliance from the wiring quickly, which is why we check both before recommending any rewiring.
