Electrical Fault Finding Across Brechin, Angus
Brechin Sparks is James Leslie, working from a base in Brechin and covering the DD9 postcode area, Montrose, Forfar, Arbroath, Edzell and Dundee within an approximate 40-mile radius.
One point of contact for the investigation, the written report and any repair. If a fault cannot wait, the 24/7 Emergency Electrician page explains how an urgent visit works. Where testing shows the board itself is the problem, a consumer unit replacement is quoted separately, and a full inspection of the installation is a separate EICR rather than a fault investigation.
“James was very polite and sent over the quote immediately after the call and came out the same day in the early evening.”
“He couldn't of been more helpful and still only took what he quoted for, even though it was a bigger job than expected. Definitely recommend.”
“Arrived within an hour of my call, as he said he would. Fixed the problem same afternoon, and rate was extremely reasonable!”
“They also give decent price for the job and the work done will be using James again, he is also very polite and very helpful too me.”
“Fast response during a weekend, put in a temporary fix so we got power back. Excellent service.”
“Very professional and courteous. Highly recommend him.”

Common symptoms
Why Does My Electricity Keep Tripping?
Usually because a protective device is doing its job: an RCD trips when current leaks to earth, and a circuit breaker trips when a circuit is overloaded or short-circuited. Electrical faults—such as an RCD tripping randomly, sockets losing power, or lights flickering—are symptoms of underlying issues inside your walls or appliances. The cause is found by testing, not by guessing.
An RCD that trips randomly
Hidden neutral-to-earth faults, moisture ingress in outdoor cables or a failing internal appliance element can all trigger the main safety switch.
A circuit breaker that keeps tripping
Nuisance tripping is a symptom, not the fault. Repeatedly resetting the switch can lead to wire melting or electrical fires.
Power that comes and goes in specific rooms
Loose connections, high-resistance joints or burnt cables behind faceplates cause unexpected loss of power.
Dead sockets or flickering lights
Traced with calibrated insulation resistance, earth loop impedance and RCD testing rather than guesswork.

Signs You Should Stop Resetting and Call
Guessing or repeatedly resetting switches can lead to wire melting or electrical fires. If any of the following applies, leave the circuit off and call James rather than trying the switch again:
A breaker that trips immediately on reset
A device that will not stay on, or trips the instant it is reset, is usually holding a live fault on that circuit. Leave it off and have the circuit tested.
Warm or discoloured sockets and switches
Heat, browning or a faceplate that has started to distort can indicate a loose or high-resistance connection behind it. Stop using the accessory and do not touch it to check its temperature.
A burning smell or buzzing from the board or a fitting
A hot-plastic smell, crackling or a hum from the consumer unit, a socket or a light fitting needs urgent assessment. Switch off at the main switch if it is safe to reach and keep clear.
Water near electrics
A leak into a light fitting, a socket, an outdoor cable or the consumer unit is a common cause of RCD tripping and a risk while the circuit stays live. Leave it off until it has been inspected and dried out.

How it works
How Is an Electrical Fault Traced?
A fault investigation works from the symptoms to the cause, one circuit at a time. What each visit involves:
Describe the symptoms and when they started
Which device trips, which rooms or sockets are affected, whether it happens with a particular appliance, in wet weather or at a certain time of day. This narrows the search before the visit and sets the investigation scope, which is agreed by phone.
Isolate and inspect the consumer unit and affected accessories
With the supply safely isolated, the board, the tripping device and the sockets, switches and fittings on the affected circuit are opened up and inspected for loose terminals, heat damage, moisture and past alterations.
Test the circuit to narrow the fault
Insulation resistance, continuity and RCD operation are measured with calibrated test equipment. Splitting the circuit and retesting shows which section, joint or appliance is responsible.
Make safe, or repair where agreed
A confirmed fault is either repaired on the spot, where the parts are to hand and the cost has been agreed, or isolated and made safe with a quote for the permanent repair.
Report the findings and next steps in writing
You receive a written note of what was checked, what was found, what was done and what remains outstanding, with photographs of any damaged cables and a recommendation for what to do next.
Small repairs found during an investigation, such as a replacement socket or switch, are covered under Small Electrical Repairs.
After testing
Private Written Investigation Reports & Photo Proof
Following testing, you receive a clear written report explaining what was checked, photographic proof of any damaged cables found, and an upfront quote for permanent repairs.
Written Investigation Report
A clear written report explaining what was checked, the findings, any work completed during the visit, anything left outstanding and the recommended next steps. Test readings are noted where they support the finding.
Photographic Proof
Photographic proof of any damaged cables found, taken during the investigation so you can see what was behind the fault before it is repaired or covered over.
Upfront Quote for Permanent Repairs
An upfront quote for permanent repairs, with costs agreed before any work begins. Where a repair is completed on the visit, the report records it; anything else is quoted for your approval.
Related Inspections & Protection
A fault investigation looks at the circuits showing symptoms. A full inspection of the fixed installation is a separate job under Landlord EICRs, and protection for electronics and appliances is covered under Surge Protection.

Frequently Asked Questions About Electrical Fault Finding
Why does my RCD keep tripping?
An RCD trips when it detects current leaking to earth, so repeated tripping usually means something on the protected circuits is leaking. Common causes include a faulty appliance, moisture in an outdoor cable or fitting, a neutral-to-earth fault in the wiring or, less often, a worn RCD itself. Unplugging appliances one at a time can point to a faulty appliance, but a wiring fault can only be confirmed by testing. James tests the circuits and reports what was found.
Is a tripping circuit breaker dangerous?
The trip itself is the breaker doing its job: it has disconnected a circuit that was overloaded or had a fault. What needs attention is the cause. A breaker that trips repeatedly, or will not stay on when reset, indicates a fault that has not gone away, and repeatedly resetting it can lead to wire melting or electrical fires. Leave the circuit off and arrange an investigation.
Why do my lights flicker?
Flickering can have several causes, from a loose connection at a switch, fitting or in the consumer unit to a lamp or dimmer that is not compatible, or a problem with the incoming supply. Flickering confined to one fitting is often local to it; flickering across several rooms is more likely a connection or supply issue and should be investigated rather than assumed. James traces where the flicker originates and explains what he finds.
Can you find a fault the same day?
Sometimes, but it is not something that can be promised. It depends on availability on the day and on the fault itself: some are traced and repaired on the first visit, while an intermittent fault or one needing parts can take more than one. Investigation scope agreed by phone before visit. For a fault that cannot wait, phone to check the next available visit.
Will I get a report?
Yes. Following testing, you receive a clear written report explaining what was checked, photographic proof of any damaged cables found, and an upfront quote for permanent repairs. It also notes any work completed on the visit and anything left outstanding, so you have a record for your own files, a landlord or a letting agent.
Do I need a full EICR or just fault finding?
Fault finding is the right job when something specific is wrong: a device that trips, a dead socket or power that comes and goes. It looks at the circuits showing symptoms and aims to find and fix the cause. An EICR is a condition inspection of the whole fixed installation, reported against the wiring regulations, and does not repair anything. If a fault investigation uncovers wider concerns about the installation, James says so and a full inspection can be quoted separately.
