Electrical Wiring Repair London
A wiring fault rarely announces itself clearly. It’s usually a socket that’s stopped working, a light that flickers for no obvious reason, or a circuit that trips intermittently, and the actual cause could be anything from a loose connection to damaged cable insulation hidden behind a wall. First Strike Electrical Ltd has repaired electrical wiring across London properties since 1999, and as an NICEIC approved contractor, we diagnose the fault properly before touching anything, rather than guessing and hoping.

What’s Involved in a Wiring Repair
We start by isolating the affected circuit safely, then use proper test equipment, not just a process of elimination, to trace exactly where the fault is and what’s causing it. Once we know what we’re dealing with, we’ll explain the options: sometimes it’s a straightforward repair to a single damaged section or connection, sometimes it’s evidence that a wider section of wiring needs replacing rather than patching. Straightforward repairs and like-for-like replacements generally aren’t notifiable work under Part P of the Building Regulations, though if a repair extends into new circuit work, notification requirements can apply, and we’ll advise you specifically on your situation.
Common Wiring Faults We Diagnose and Repair
- Sockets or circuits that have stopped working entirely
- Intermittent faults that come and go
- Damaged cable following building work, DIY, or pest damage
- Faults caused by old or degraded cable insulation, particularly in older London properties
- Loose or corroded connections at sockets, switches or the consumer unit
- Faults following water ingress from a leak or flood
Why Diagnosis Matters More Than a Quick Fix
Resetting a tripped breaker and it working fine afterwards feels like a solved problem, but if it trips again, the underlying cause hasn’t actually gone anywhere. Properly diagnosing a wiring fault, rather than just clearing the symptom, is the difference between a repair that lasts and one you’ll be calling about again in a few months. We’ll always tell you honestly if what looks like a small issue on the surface actually points to something bigger, such as ageing wiring that’s due for a partial or full rewire, rather than another isolated repair.
Older London Properties and Historic Wiring
Victorian and Edwardian conversions in particular sometimes still have sections of very old cable, lead-sheathed or early rubber-insulated types, that have long since degraded even if they haven’t caused an obvious fault yet. Where we find this during a repair, we’ll flag it clearly rather than just patching the immediate issue and leaving the rest, since it’s the kind of thing that tends to cause the next fault sooner rather than later.
Why Choose First Strike Electrical
NICEIC approved, so our diagnostic and repair work is assessed against national standards, and trading in London since 1999, we’ve traced enough wiring faults in period properties and modern builds alike to generally know where to start looking. We’re upfront about pricing before starting non-emergency repair work, and honest if a repair turns out to be a bigger job than it first appeared.
Frequently Asked Questions
How do you find a wiring fault that isn’t obvious?
Using proper test equipment to trace the fault systematically, rather than guessing, checking insulation resistance, continuity and other electrical tests to pinpoint exactly where the problem is.
Is a wiring repair notifiable work?
Generally not, if it’s a straightforward repair or like-for-like replacement. If it extends into new circuit work, notification can apply, and we’ll tell you which situation applies to your repair.
What if the fault keeps coming back after a repair?
That’s usually a sign the underlying cause wasn’t fully resolved, or that there’s a wider issue with the wiring. We’ll always investigate properly rather than repeatedly patching the same symptom.
Do you offer emergency wiring repairs?
For genuinely urgent faults, such as exposed wiring or sparking, see our emergency electrician London page. For non-urgent repairs, we work to a scheduled appointment.
My property is quite old, does that make repairs more complicated?
Sometimes. Older cable types can be more fragile to work with and occasionally point to a wider issue beyond the immediate fault, which we’ll always explain clearly rather than just patching around it.
