Things You Should Never Ignore
If you don’t fix small electrical problems, they can turn into bigger ones. If you see any of the signs below, you should get a professional to look at them.
Repeated RCD or Circuit Breaker Tripping
If your RCD or breaker keeps turning off, there is usually something wrong with the circuit. It could be too much power, broken insulation, or a broken appliance.
Flickering or Non-Functioning Lights
If your lights dim, flicker, or go out completely, it could be because of loose connections, voltage problems, or bad wiring.
Burning Smells or Warm Sockets
If you smell something burning or “fishy,” that’s a big warning sign. It could mean that the wires are too hot or the insulation is broken. This needs to be checked right away.
Partial Power Loss
If only part of your property has lost power, the problem might be with just one circuit.
Electric Shocks or Sparking
Even a mild tingling sensation from a socket or appliance is not normal. This suggests a potential earthing issue.
Unusual Energy Bills
Sometimes, a sudden rise in electricity use can be traced back to faulty wiring or hidden load issues.
Ignoring these signs can increase the risk of fire, appliance damage, or injury.
What Causes Electrical Faults in Residential and Commercial Properties?
Electrical systems wear down over time. Modern homes also use more power than ever before.
Common causes include:
- Overloaded circuits because of appliances that need a lot of power are a common cause.
- Loose connections that generate heat
- Damaged or ageing cables
- Insulation breakdown
- Ground faults and poor earthing
- Water damage from leaks
- Outdated fuse boards or consumer units
Commercial properties may also face issues such as load imbalance or three-phase supply faults.
Understanding the root cause is essential. Replacing parts without proper diagnosis often leads to repeat problems.
Our Structured Electrical Fault Finding Process
We follow a clear, step-by-step method. This removes guesswork and ensures long-term safety.
Initial Consultation
We want to know what the symptoms are, when they happen, and what has changed in the property recently.
Visual Inspection
We look for signs of heat damage, wear, or moisture on the consumer unit, sockets, switches, and wiring that we can see.
Targeted Circuit Testing
Using calibrated test equipment, we test voltage, resistance, and circuit continuity.
Insulation Resistance Testing
If needed, we test cable insulation to detect hidden breakdown or leakage.
Circuit Tracing
We trace the circuit path to isolate the exact section where the fault exists.
Thermal Imaging
Thermal cameras help us detect overheating without removing large sections of walls or ceilings.
Safe Repair
We repair or replace the faulty component.
Final Re-Testing
Every circuit is tested again to confirm safe operation.
Advanced Diagnostic Tools & Testing Methods We Use
Accurate diagnosis depends on the right equipment.
We use:
Tool | Purpose |
Multimeter | Tests voltage, current and resistance |
Insulation tester | Detects cable insulation breakdown |
RCD tester | Confirms RCD trip times and performance |
Earth loop tester | Checks earthing integrity |
Thermal camera | Detects overheating components |
All equipment is calibrated and used in accordance with UK standards.
Compliance, Certification & Electrical Safety Standards
Electrical work in the UK is regulated. We carry out all fault finding and repairs in line with:
- BS 7671 – 18th Edition Wiring Regulations
- Part P Building Regulations (domestic properties)
- Electrical Safety Standards in the Private Rented Sector (England) Regulations 2020
Where required, we issue:
- Minor Electrical Installation Works Certificates
- Updated EICR documentation (if applicable)
For landlords, compliance is a legal duty. For businesses, it supports insurance and health & safety requirements.

Emergency Electrical Fault Finding – When Immediate Action Is Required
Some faults cannot wait.
Call us urgently if you notice:

- Total power failure
- Exposed wires
- Electric shock
Before we arrive, if safe to do so:
- Switch off the affected circuit
- Unplug connected appliances
- Avoid using the faulty area
Electrical emergencies should never be ignored.
Clear pricing for diagnosing electrical problems
We use a clear pricing model that starts with a diagnosis, so you’ll always know what you’re paying for. The final cost will depend on how complicated the problem is, how long it takes to find it, and any parts that are needed to make the repair safely. We check out each electrical problem before giving you a final price because every one is different.
We explain the problem and the best way to fix it before any work starts. There are no extra fees or hidden costs that come up later. We will honestly explain all of the repair options to you so that you can make an informed choice.
We always try to fix the problem in the right way and safely. We don’t replace parts that don’t need to be replaced or do work that isn’t needed. Our goal is to give you a reliable, long-term fix that keeps your property safe and makes you feel good about your electrical system.
What do we do after we find the problem?
We can often fix the problem on the same visit. After finding the problem and safely isolating it, we fix it and then test the circuit again to make sure everything is working properly and safely.
If the problem needs more work than we can do, we will give you a clear written estimate before we start. We take the time to explain any compliance requirements, especially if the repair has to do with the consumer unit, fixed wiring, or landlord certification. You will know exactly what to do and why.
After that, we set up the repair for a time that works for you, so there isn’t too much disruption. We always work in a professional and organised way.
We may suggest the following if needed:
If the consumer unit no longer meets current safety standards, it needs to be upgraded.
Rewiring parts of the cable that are broken or worn out
Doing regular maintenance checks to lower the chance of problems in the future
Safety and dependability over the long term are our top priorities. We don’t offer quick fixes. We want to make sure that your electrical system stays stable, safe, and up to code for a long time.

Electrical fault finding is the process of figuring out what’s wrong with an electrical system so you can find out what’s causing problems like circuits that trip, power loss, or parts that get too hot.

Finding faults is not a legal requirement, but landlords and businesses are legally required to keep electrical systems safe. Finding and fixing problems helps you meet these responsibilities.
How long does electrical fault finding take?
Most diagnostics take one to three hours, depending on how complicated the installation is and what kind of problem it is.

Yes, in a lot of cases. If the parts are available and the problem is simple, repairs are often done during the same appointment.
Do you offer emergency electrical fault finding in London?
Yes. We offer emergency and same-day fault finding services throughout London, as long as we have the time.
Is fault finding disruptive?
We try to keep our diagnostic methods from causing too much disruption. We focus on testing that is specific to the problem instead of taking things apart that don’t need to be.
How much does electrical fault finding cost?
The costs depend on how long it takes and how complicated the system is. Before we start working, we give you clear prices and free estimates.
Can you provide reports for landlords or insurers?
Yes. We can give you clear papers that list the problems we found and the steps we took to fix them.
