Why Faults Play Hide and Seek
An intermittent supply is usually a joint that is part-making and part-breaking. Metal expands as it warms under load and contracts as it cools; a loose terminal opens when it is hot and makes contact again when it cools, which is why the hall lights work all evening and die just after the kettle boils. Movement does the same: a cable flexed by a door, a joint disturbed by vibration, a conductor half-broken where it was nicked years ago. Protective devices can add their own pattern, dropping a circuit when the heating element inside a fitting reaches temperature and letting it reset once it cools.
What Intermittency Is Telling You
Every open-and-close cycle at a bad joint produces a small arc, and every arc erodes and heats the contact a little more. The intervals get shorter and the dropouts get longer until the connection fails for good — usually at the least convenient moment, and occasionally in a way that damages whatever is plugged in. Treat the intermittency itself as the warning: it is not a quirk to live with but a connection on its way out.
The Pattern Is the Clue
Before we arrive, it helps to notice when it happens: the same time of day, when particular appliances run, in certain weather, after the circuit has been on a while. Whether one room or several are affected narrows the search enormously — one socket suggests a local joint, a whole circuit points upstream, and the whole house suggests the supply side or the consumer unit.
How We Catch an Intermittent Fault
With the circuit isolated and proven dead, we inspect and test the likely joints — terminations at the fittings you named, then junction boxes and connections along the route. Resistance testing reveals joints that look sound but measure high; a gentle disturbance test under supervision can reproduce the dropout safely. Where the fault hides deeper, we measure at accessible points and narrow the run down section by section, or monitor the circuit live with the protection in place until the dropout occurs. Intermittent faults take patience, but they are findable — the mistake is swapping fittings at random rather than testing methodically.
How We Fix It Properly
Once found, the joint is remade from scratch: cut back to bright copper, refitted or re-terminated with the right connector, tightened correctly, and any conductor that has been arced or overheated is replaced rather than reused. Cable that has been flexing in the same spot is rerouted or supported so the movement stops. Then we test the circuit under load and, where the fault history suggests it, check the whole run's other joints — the same age and the same trades usually mean the same weaknesses nearby.
Life Afterwards
Most intermittent faults never return once the connection is properly remade. We will tell you what to watch for on the affected circuit — flicker, warmth, crackle — and what it would mean if it reappeared, so you can act on it early rather than wonder.
When to Call Us
Book a visit for any power loss that comes and goes, sockets that work only at an angle, lights that respond to being touched, or breakers that trip in a pattern you can almost predict. A burning smell, warmth or scorching alongside the intermittency turns it into a same-day job.

A fault that hides when you watch it will not hide from proper instruments and a methodical engineer. Call or book online and we will trace the dropping connection, remake it soundly, and give you back a supply you can stop thinking about.
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.

We diagnose on site
The engineer confirms the cause and tells you what the job involves and how long it should take.
You approve, we work
Nothing goes ahead until you agree the price. Labour is then charged per hour at your slot rate.
A circuit that works this morning and dies this afternoon, a lamp that flickers back to life when someone walks past, a socket that only behaves when the plug is at exactly the right angle — intermittent faults are frustrating precisely because they hide while anyone watches. They nearly always come down to a connection that opens and closes as it heats, cools or moves. We instrument the circuit, catch the fault in the act, and remake the connection so it stops performing for you.
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.

Questions people ask about intermittent power supply
Straight answers to the things customers ask most often before booking.
How much will it cost to trace an intermittent fault?
You pay a booking fee when you book, and labour is charged hourly at a rate that depends on how soon you need us. Intermittent faults can take longer to pin down than obvious ones, so we keep you informed as we go and quote the full repair before we carry it out.
Can I find an intermittent fault by swapping sockets around?
Swapping fittings without testing usually replaces parts that were never the problem, and it disturbs connections that were sound, sometimes creating a new fault. Without instruments you also cannot tell a high-resistance joint from a healthy one, even with the faceplate off. A methodical test finds it faster than guesswork.
What will the engineer do differently for an intermittent fault?
We start with the pattern you have noticed — timing, weather, which appliances — because that narrows the search more than anything. Then it is isolation, testing of joints along the likely route, and safe disturbance testing to reproduce the dropout. The aim is to catch the fault in the act, not to replace parts until it stops.
Is it dangerous if the power comes back on by itself?
A supply that restores itself means a connection is opening and closing, and each close is a small arc at the joint. That erodes and heats the contact over time, and the end point is often a failure that also damages whatever is plugged in. It should be traced and repaired, not tolerated.
The fault only happens in cold weather — does that mean anything?
Yes, quite a lot. Cold contracts metal, so a marginal joint can open in winter and close again when the house warms, and damp getting into an outdoor or cavity connection behaves the same way. Seasonal faults are still real faults, and we will look closely at anywhere moisture or movement could reach the wiring.
