Common electrical faults in EN1
Understanding electrical faults in London properties
Circuit breaker tripping
MCBs (miniature circuit breakers) trip on overload, short circuit, or wiring fault. When a breaker trips, the first step is to identify the problem circuit. Isolate at the consumer unit, switch off all MCBs, then restore them one at a time to identify which circuit is at fault.
If a single socket or appliance causes the trip, the fault is likely in that appliance. If the breaker trips when no appliance is connected, a wiring fault in the circuit is the probable cause. Repeated tripping without an obvious appliance fault indicates insulation breakdown in the wiring — this requires a qualified electrician to test, locate, and repair.
RCD tripping
RCDs (residual current devices) operate at a 30mA threshold and trip on earth faults or shock risk. Unlike MCBs, an RCD trip means there is an earth fault somewhere in the circuits it protects. To identify which circuit is at fault, isolate each circuit in turn with the RCD switched off, then restore the RCD to see if the trip clears.
Common culprits include a damaged cable in the garden, a faulty white goods appliance (dishwasher, washing machine), or a shower cable fault. Modern split-load consumer units have two RCDs — one RCD can continue protecting circuits while the other is investigated, maintaining partial power to the property during diagnosis.
Failed sockets
Burn marks around a socket face indicate overheating from a loose connection or excessive load — the socket must be replaced immediately and the wiring behind it inspected. A dead socket with no burn marks is usually a loose connection at the back terminal: the wire has worked free of the terminal and the circuit is open.
A single socket circuit is rated at 13A maximum per outlet — overloading a socket with an extension lead running multiple high-draw appliances causes overheating over time. Sockets installed near water zones — bathrooms, kitchen sink zones — require IP-rated fittings. A standard socket is not rated for damp zones and must not be installed within the zones defined by BS 7671.
Flickering lights
Flickering is usually a loose connection at the switch, ceiling rose, or terminal block — a straightforward repair once the fault is located. It can also indicate an undersized circuit or an aging dimmer switch that is not compatible with LED bulbs. Old leading-edge dimmers, designed for incandescent bulbs, cause flickering and buzzing when used with modern LED lamps. Trailing-edge LED-compatible dimmers resolve the compatibility issue entirely.
London properties: wiring across eras
Many Victorian properties in London have been extended multiple times over the decades; wiring from completely different eras may be present in the same property. Older rubber-insulated cables, installed before the 1970s, become brittle and crack over time — the outer sheathing crumbles, exposing bare conductors. These cables are a fire and shock risk and must be replaced.
Rewirable fuses in old fuseboard panels offer no RCD protection — if the fuse does not blow fast enough, a shock or fire can occur. Consumer unit upgrades are strongly recommended for any property with a rewirable fuseboard. Lead sheathed cables found in some pre-war London properties must be treated as immediately dangerous and isolated without delay.
Part P compliance
Replacement of sockets, switches, and light fittings is notifiable work in some zones — specifically rooms that contain a bath or shower, and locations within 3 metres of a shower. NICEIC-registered electricians self-certify this work under Building Regulations Part P, meaning no separate building control notification is required. A Building Regulations Completion Certificate is issued on completion, providing full legal compliance documentation.
Outdoor electrical repairs
Garden sockets, security lighting, gate motors, and outdoor circuits must be protected by a dedicated RCD and must use weatherproof IP-rated fittings throughout. Cables buried in gardens must follow prescribed routes per BS 7671 (IET Wiring Regulations 18th Edition). Cables less than 50mm deep require mechanical protection such as conduit; cables at 500mm depth in the prescribed cable zones of a garden do not require additional mechanical protection.
External circuits must run on a dedicated circuit from the consumer unit — sharing with an internal circuit is not compliant under current wiring regulations. All outdoor electrical repair work in EN1 includes full RCD protection and weatherproof terminations as standard.
Emergency electrical repairs
No power, sparking outlets, or a burning smell must be treated as an emergency. Isolate at the consumer unit or main switch before calling — do not attempt to investigate a sparking or burning outlet yourself. We attend emergency electrical faults across London 24 hours a day. Call-out from £80; most repairs are completed in 1 to 2 hours. Socket replacement costs £60 to £120; RCD fault diagnosis £80 to £150; emergency electrical repair from £120 to £200 call-out. Light fitting replacement from £50 to £100.

Electrical repair services
Socket and Switch Repair
Replacement of failed, burnt, or loose sockets and switches. Dead sockets with no burn marks are often a loose connection at the back terminal. Burn marks indicate overheating and require immediate replacement.
RCD Fault Finding
RCDs trip on earth faults or shock risk. We identify which circuit is causing the RCD to trip, locate the fault — whether a damaged cable, faulty appliance, or wiring defect — and carry out the repair.
Circuit Breaker Diagnosis
An MCB trips on overload or short circuit. We diagnose whether the trip is caused by an overloaded circuit, a wiring fault, or a faulty appliance, and advise on the correct rectification.
Light Fitting Repair
Faulty light fittings, intermittent lighting, and flickering caused by loose connections at the rose, switch, or terminal block. Dimmer switch replacement for LED compatibility. Ceiling rose and pendant replacement.
Outdoor Electrical Repair
Garden sockets, security lighting, gate motor wiring, and outdoor circuits. All outdoor electrical work uses weatherproof fittings and RCD protection. Cable routes comply with IET Wiring Regulations.
Emergency Electrical Repair
No power, sparking outlets, burning smell — treated as emergency. Isolate at the consumer unit and call immediately. We attend emergency electrical faults across London 24 hours a day.
