Everything below is what an honest, NAPIT-approved contractor will actually do for you, not what a marketing agency thinks sounds good on a website. What it covers Fault finding is the diagnostic side of the trade, using calibrated insulation resistance testers, loop testers, RCD testers and thermal imaging to isolate exactly why something is tripping, running hot, or failing to work. Maintenance is the planned upkeep side, periodic inspection, remedial works from EICRs, reactive repairs, and keeping domestic and commercial installations compliant and reliable. Who it's for Homeowners with nuisance tripping, dead circuits or intermittent faults; landlords whose tenants keep calling about dead lights; commercial and light industrial operators who need reactive support; facilities managers wanting planned inspection cycles rather than reactive-only maintenance. When you need it The second something intermittent starts, because intermittent faults get worse and become permanent (usually at the worst possible moment). Immediately if you smell burning, see scorching around a socket, or have an RCD that won't reset. Why professional matters Guess-and-check fault finding is expensive, you pay for the wrong parts, then pay again for the actual fix. Proper testing with calibrated instruments isolates the fault the first time. Preventive maintenance is a fraction of the cost of reactive repairs, especially in commercial premises where downtime costs trading revenue. What Happens If You Leave It ## The cost of putting it off. Every one of these is something we see weekly. None of them get better on their own. ### Intermittent faults become permanent, usually at 6am A circuit that trips once a week becomes one that won't reset. Diagnose it early and the fix is small; leave it and you're paying an emergency call-out. ### Scorching and burning smells are pre-fire warnings Any smell of burning plastic near sockets, switches or the consumer unit is a live fire risk. Isolate the circuit and call immediately. ### 'Fixed' by unqualified hands, twice as expensive The most expensive fault finds are the ones where 'someone had a go' first, swapped parts, wrong terminations, and buried problems we then have to unpick before diagnosing. ### Missed EICR remedials = unlettable / uninsured Failing to action C1 / C2 codes from an EICR keeps the property non-compliant. Landlord and buildings insurance can be refused on that basis. Our Process ## How the job actually runs, start to finish. Step 1 ### Phone triage We'll ask the right questions on the phone so you're not paying a call-out just to be told what you already suspected. - Step 2 ### On-site inspection Visual inspection, isolation of suspect circuits, thermal check where relevant. - Step 3 ### Instrument testing Insulation resistance, earth loop, RCD trip time, polarity, calibrated instruments, logged results. - Step 4 ### Isolate & fix Once diagnosed, we quote the fix before doing it. No 'while we're here, that'll be another £X' at the end. - Step 5 ### Re-test & certify Post-repair testing, Minor Works Certificate issued, and a note of what actually caused the fault so it doesn't come back. Benefits ## Why customers stick with us. ### Calibrated test kit, not guesswork Every fault find uses calibrated instruments, results logged so the diagnosis is defensible. ### Fixed-price fault find, then fixed-price repair Diagnosis priced separately from the fix, so you're never paying for time we can't justify. ### Same electrician start to finish The person diagnosing is the person fixing, nothing lost in handover. ### Planned maintenance cycles for commercial Quarterly / annual planned inspection instead of reactive-only. ### 24/7 line for genuine emergencies Real out-of-hours response, not an answerphone. ### Root cause, not just symptom We find the actual reason, not just reset the breaker. So it doesn't come back. In Detail ## Everything else worth knowing. The specific materials, methods and situations that make this job go well, or badly, depending on who's doing it. Request A Free Estimate ### Common faults we diagnose weekly Nuisance-tripping RCDs (usually accumulated small earth-leakage from multiple appliances stacking up over one RCD, or a specific circuit with insulation degradation), dead ring mains (loose terminations at faceplates, thermal damage from historic overload), flickering lights (dimmer / LED incompatibility, loose neutral, or supply-side issues), warm sockets (loose terminals, undersized cabling, chronic overload), and consumer units with a scorched terminal (loose termination running hot for months). ### How we actually diagnose Every fault find follows the same discipline: isolate, visually inspect, then use calibrated instruments. Insulation resistance (megger) testing at 500V DC finds cable and appliance-side insulation faults. Earth fault loop impedance testing verifies protective devices will disconnect within the required time. RCD ramp and trip-time testing verifies protection is working to spec. Thermal imaging (used on request for commercial distribution boards) finds loose terminations before they fail. ### Planned maintenance for commercial premises For commercial and light industrial clients we offer planned inspection cycles, typically quarterly emergency-lighting function testing, annual full-duration testing, PAT testing on a schedule that matches your equipment risk, and periodic thermal imaging of distribution boards on request. Planned cycles are always cheaper than reactive-only maintenance, and they generate the paperwork your insurer wants to see. ### Residential vs commercial, where it differs Domestic fault finding is usually a single isolated fault, one tripping circuit, one dead socket. Commercial fault finding often involves distribution and sub-mains, higher continuous loads, and much lower tolerance for downtime. Both use the same core discipline; commercial jobs are just scheduled differently and documented more heavily. Common Questions ## Maintenance & Fault Finding, answered. Straight answers to the questions we get on the phone every week. If yours isn't here, call 07782 498471 and ask. ### How much does a fault find cost? +Diagnosis is priced separately from the fix. Our call-out is £80. Once diagnosed, we quote the repair before doing it, you approve, we fix. No open-ended time charging. ### How quickly can you come out? +For genuine emergencies (loss of power, burning smell, exposed conductors) our 24/7 line responds as fast as travel allows. For non-urgent work, usually within a few days. ### My RCD keeps tripping, can you find out why? +Yes, this is one of the jobs we do most often. Almost always diagnosable in a single visit with a proper insulation resistance test. ### Do you handle intermittent faults that only happen occasionally? +Yes, intermittent faults are our bread and butter. We use calibrated testing plus visual and thermal inspection to isolate them rather than guess. ### Do you certify the repair? +Yes, Minor Works Certificate issued after any repair, with a note of the actual cause so it's on file. ### Do you offer planned maintenance for commercial premises? +Yes, planned inspection cycles including emergency lighting testing, PAT testing and thermal imaging on request. ### Is there a guarantee on the repair? +Workmanship is backed by our NAPIT registration; parts carry their manufacturer guarantees. ### What's the difference between a fault find and an EICR? +A fault find diagnoses a specific reported issue. An EICR is a full periodic inspection and test of the whole installation, resulting in a coded report. We do both.
