An electrical fault finding service is a systematic diagnostic process where a qualified electrician identifies the root cause of a fault in your wiring, circuits, or consumer unit — then advises you on the safest, most cost-effective fix. If you're dealing with a dead socket, a circuit breaker that keeps tripping, or flickering lights you can't explain, getting a proper diagnosis before assuming the worst will almost always save you time and money.

Fault finding isn't the same as a standard repair call-out. When something goes wrong with your electrics, the visible symptom — a tripped breaker, a dead circuit, a buzzing light fitting — is rarely the whole story. An electrician carrying out fault finding is working backwards from that symptom to identify why it's happening, and crucially, whether it's a one-off failure or a sign of something more serious in the installation.
Good fault finding draws on a working knowledge of BS 7671 18th Edition Wiring Regulations, proper test equipment, and the kind of experience that only comes from spending years on different types of domestic and commercial installations. At Energy North Ltd, we work across Teesside and County Durham, and that means seeing everything from 1930s houses in Middlesbrough with older wiring to modern new-builds in Darlington with complex consumer unit arrangements. The age and type of property matters when you're trying to track down a problem.

In our experience across Middlesbrough, Stockton-on-Tees, Hartlepool, and the wider Durham area, certain faults come up repeatedly:

There's no single template because every fault is different, but in practice the process follows a logical sequence:
1. Initial conversation — We ask what symptoms you've noticed, when they started, and whether anything changed beforehand (new appliances, recent DIY work, bad weather). This context is genuinely useful.
2. Visual inspection — Before any test equipment comes out, we look at the consumer unit, accessible cabling, sockets, light fittings, and any obvious signs of damage or poor previous work.
3. Isolation and dead testing — Where safe and appropriate, we isolate circuits and carry out dead tests including insulation resistance tests and earth continuity tests to check the integrity of the wiring.
4. Live testing — Once we've established it's safe to energise, we carry out live tests including loop impedance tests to check earth fault path impedance, and RCD operation tests.
5. Fault identification — Based on the test results and visual findings, we'll tell you clearly what the fault is, what caused it, and what the options are for putting it right.
6. Written record — Any test results and findings are documented. If the work forms part of a notifiable job under Part P Building Regulations, the appropriate certification is issued.

Professional fault finding requires calibrated, properly maintained test equipment. We use the Megger MFT1741 multifunction installation tester as our primary instrument — it handles insulation resistance tests, earth continuity tests, and loop impedance tests in one unit and produces results you can rely on. A Fluke clamp meter is useful for measuring load currents without breaking circuits, which helps identify overloaded circuits without the need for unnecessary disconnections.
For certain faults — particularly where we suspect overheating connections behind finished surfaces — a thermal imaging camera is a genuinely valuable tool. It allows us to scan distribution boards and cable runs for hot spots that wouldn't otherwise be visible without destructive investigation. It doesn't replace electrical testing, but it adds a layer of information that can make diagnosis significantly faster and more accurate.

Sometimes fault finding reveals that the fault itself is minor, but the surrounding installation raises concerns. This is particularly common in older properties where the electrics haven't been touched in decades. A tripping circuit breaker might lead us to a consumer unit with no RCD protection, deteriorated cable insulation with low insulation resistance readings, or an incomplete earth arrangement that doesn't meet current standards.
Where a consumer unit replacement is required — perhaps upgrading to a fully-split load board with RCBO protection on individual circuits — that work is notifiable under Part P Building Regulations and must be carried out by a competent person registered with a scheme such as NICEIC or NAPIT. We'll always be straight with you about what's a legal requirement, what's a strong recommendation, and what can wait.
A full rewire is a bigger conversation, and we'd never push someone toward one unnecessarily. But if test results show widespread insulation failure, or we're dealing with rubber or fabric-insulated cables, it's our job to tell you honestly rather than patch over the problem.

Landlords in Teesside and County Durham have specific legal obligations around electrical safety. Since 2020, the Electrical Safety Standards in the Private Rented Sector Regulations require landlords to have a valid EICR (Electrical Installation Condition Report) carried out by a qualified person at least every five years, and to provide a copy to tenants.
If a fault has been found and repaired, that repair should be documented. If it was identified during an EICR and constituted a C1 (danger present) or C2 (potentially dangerous) code, the remedial work must be completed and a satisfactory report issued within 28 days — or sooner if specified. A landlord electrical certificate after fault rectification gives you the paper trail you need to demonstrate compliance.
We work with landlords across Middlesbrough, Darlington, Hartlepool, and across County Durham, and we understand that minimising void time matters. We'll work with you on timing where we can.

Familiarity with the local housing stock is worth more than it sounds. An electrician who has worked in Teesside for years will have seen the particular quirks of the area — the post-war housing estates, the older terraces, the conversion properties, the new-builds on the edge of Darlington. Local knowledge also means realistic response times and the ability to return if a fault proves complex.
Energy North Ltd is based locally and serves homeowners, landlords, and businesses across the Teesside and Durham area. Our work is carried out to BS 7671 18th Edition standards, and where registration is relevant, we work within the appropriate regulatory frameworks.

How much does electrical fault finding cost in Teesside and Durham?
Call-out and fault finding rates vary depending on the time involved, the complexity of the fault, and whether any repairs are needed on the day. Typically you'd expect to pay for a minimum period of attendance plus an hourly rate thereafter — in the North East, that might range broadly from around £60–£120 for an initial attendance, but this varies by contractor and job type. We'll always give you a clear idea of costs before work begins, not after.
How long does it take to find an electrical fault?
Simple faults — a failed socket, a tripped breaker caused by a faulty appliance — can be diagnosed in under an hour. Intermittent faults, or faults spread across multiple circuits in a large property, can take considerably longer. It's honest to say that some electrical faults are genuinely time-consuming to trace, and a contractor who tells you it'll always be quick hasn't been doing this very long.
Why does my RCD keep tripping but nothing seems wrong?
This is one of the most common questions we get. An RCD trips when it detects a leakage current to earth above its threshold — typically 30mA for a Type A RCD in domestic installations. The source of that leakage can be a faulty appliance (try disconnecting appliances one at a time), moisture in an outdoor socket or cable, a deteriorating cable with reduced insulation resistance, or occasionally an RCD that is itself ageing and becoming overly sensitive. Systematic testing is the only reliable way to identify the source.
Can a fault finding visit turn into a full repair on the same day?
Often yes, particularly for straightforward faults — replacing a socket, tightening connections, replacing a faulty MCB or RCBO. We carry a range of common parts. For larger or more complex work we'll give you a quote and schedule the repair, but we won't leave you with a dangerous situation unresolved.
Do I need an EICR if a fault has already been fixed?
Not necessarily — it depends on the circumstances. If the fault was identified during an existing EICR inspection, you'll need a satisfactory remedial report to close it out. If you've had a fault repaired outside of an EICR cycle, that repair should be certified under Part P if it was notifiable work, but it doesn't automatically trigger a full EICR. That said, if your installation hasn't been inspected for a long time, or you're a landlord approaching your five-year renewal, it makes sense to combine the two.
