At Plumb London, we deliver dependable, professionally managed electrical services across London, covering everything from fault finding and lighting repairs to structured system upgrades. As a trusted property specialist with over 35 years’ trading history as a family-run London business, we understand that electrical systems can pass compliance checks yet still develop component-level faults over time, switching devices, timer circuits, external fittings and cabling are all subject to wear and environmental exposure.

Local Electricians London

In a recent electrical fault finding project in Wandsworth (SW18), we were instructed to investigate recurring electrical faults affecting both internal and external lighting within a detached property.

Although the property had previously passed an EICR in 2022, faults had developed within a timer-controlled porch lighting circuit, causing repeated tripping and instability. Compliance does not eliminate the risk of component degradation over time.

Through structured fault finding, we traced the issue to damaged wiring within the switching system. The faulty components were replaced, restoring stable operation. Additional lighting failures were resolved through targeted replacement of defective fittings and lamp holders.

In a separate project, a failed EICR for a landlord in South Lambeth (SW8) identified a consumer unit that no longer met 18th Edition wiring regulations. We supplied and installed a new fire-rated consumer unit with RCBO protection, then carried out a full EICR to confirm compliance, coordinated alongside plumbing works in a single visit for a client managing the property remotely from overseas.

External lighting plays a critical role in both safety and usability. In the Wandsworth property, failed external fittings were replaced and PIR lighting was repositioned to improve rear coverage and visibility.

Surface-mounted conduit and junction boxes were installed where required to protect cabling from environmental exposure and physical damage. This ensures durability while maintaining access for future maintenance.

All works were carried out within an occupied detached property, requiring clean installation methods and careful coordination across multiple elevations.

All work is carried out by fully qualified, experienced electrical engineers, with structured fault diagnosis as standard rather than a straight component swap. Where a fault has developed on a system that previously passed an EICR, as in the Wandsworth project, we investigate the specific cause rather than assuming the whole system is at fault, so you pay to fix what’s actually wrong.

Electrical works often form the foundation for wider property upgrades. In the Wandsworth project, following stabilisation of lighting circuits, the project progressed into a coordinated security improvement involving CCTV installation.

While CCTV wasn’t the initial focus, the structured cabling, conduit protection and system integration demonstrate how electrical infrastructure underpins effective security systems. Our team is experienced in delivering integrated electrical upgrades that support lighting, heating controls and security installations within one coordinated scope.

A properly diagnosed and upgraded electrical system protects more than compliance on paper:

  • Reduces the risk of recurring faults and repeat call-outs
  • Gives landlords and property managers a clear compliance record for tenants, insurers and mortgage lenders
  • Protects against fire risk from degraded wiring, timer circuits and switching components
  • Supports integration with security, heating and smart-home systems as part of one coordinated upgrade

We understand that most electrical work takes place in occupied homes or let properties. Our team plans each stage to minimise disruption, works cleanly across multiple elevations or rooms where required, and coordinates directly with landlords managing their properties remotely, as demonstrated in our South Lambeth project.
