What Is Electrical Fault Finding?
Electrical fault finding is the process of diagnosing problems in an electrical system. It involves tracing faults in wiring, sockets, consumer units, lighting, and appliances to identify issues such as short circuits, earth faults, or overloads. At RCD Electrical, our qualified electricians use advanced diagnostic tools and in-depth knowledge to quickly isolate and resolve faults, ensuring your safety and restoring functionality.
Typical Fault Finding Costs in London
The cost of fault finding depends on various factors, including the complexity of the issue, property size, accessibility, and time of service (standard hours or emergency). Here’s a general breakdown of what to expect when calling RCD Electrical:
-

-
Hourly Rate (after the first hour): £65 to £85 per hour

Factors Affecting the Cost
Several key elements influence how much you might pay for electrical fault finding in London:
-
Type of Fault Minor issues such as a faulty switch or socket can often be resolved quickly. More complex problems, like intermittent faults or issues within the consumer unit, may require extended diagnosis.
-
Location and Accessibility Difficult-to-access wiring, such as cables within walls or ceilings, may increase labour time and cost.
-
Property Size and Layout Larger homes or multi-storey buildings require more time to assess the full electrical network.
-
Emergency vs. Scheduled Work Same-day or out-of-hours emergency services generally incur a higher rate due to immediate availability and rapid response.

Follow-Up Work Required In some cases, resolving the fault may require additional services like rewiring, fuse board upgrades, or appliance repairs. RCD Electrical provides complete solutions with clear itemised pricing.
