Fault finding traces problems in a property's fixed electrics, such as repeated tripping, a circuit losing power or an electrical fitting behaving unexpectedly, before the right repair is agreed. Based in Banstead — also serving Sutton, Wallington, Reigate, Purley and Epsom. ## Fault-finding price The current published rate appears below. The time and final cost depend on the symptoms, access and what testing or repair is needed. - Fault finding & repair: £65/hr - Share when the problem started, what loses power and what makes it happen, if known. - Parts, concealed-access work and larger repairs are discussed and priced before they go ahead. ## Start with the symptom, not a guess Different electrical problems can look similar. A safe diagnosis narrows down the affected circuit and finds evidence before repair work is recommended. - **Repeated tripping:** An RCD or circuit breaker that keeps tripping can point to a fault in an appliance, circuit or the fixed wiring and should be investigated. - **Lost or unreliable power:** Dead sockets, lights that stop working or an intermittent circuit need methodical checks rather than repeated resets. - **Heat, damage or unusual sounds:** Burn marks, overheating, buzzing or crackling are warning signs. Stop using the affected fitting if it is safe to do so and arrange an inspection. ## What fault finding covers The electrician follows the reported symptom through the accessible fixed installation, then explains what the evidence supports. ### Included when agreed - Review of the symptoms, recent changes and previous work - Safe visual checks and electrical testing of the agreed circuit or fitting - Tracing the likely fault location as far as safe access allows - Making the affected installation safe where action is required - An agreed repair that can reasonably be completed during the booked time - Clear findings and next steps if further work is needed ### Not included automatically - Repairing portable appliances or electronic equipment - Replacement parts or specialist equipment outside the agreed price - Lifting floors, opening walls or other destructive access - Rewiring, extra circuits or larger remedial work - Testing unrelated parts of the installation ## What happens during the visit Useful details and safe access help the electrician test the right part of the installation first. 1. **Describe the pattern:** Explain what happens, when it started and anything that changed beforehand. Photos or a short video can help with intermittent faults. 2. **Isolate, test and trace:** The electrician makes the work area safe, checks the affected circuit and follows the test results to narrow down the cause. 3. **Agree the next action:** If a repair is practical within the visit, it is agreed first. Larger or access-dependent work is explained and quoted separately. ## What you receive The outcome depends on what the testing finds and whether the faulty part can be reached safely during the visit. - **Evidence-led diagnosis:** The electrician explains the likely cause and the checks that support it, including any limits on the investigation. - **A safe immediate position:** A dangerous affected circuit or fitting is not left in use while the necessary repair remains outstanding. - **Repair or clear quote:** Straightforward agreed work may be completed during the visit; anything larger is scoped before more work starts. - **Relevant test or certificate record:** You receive the appropriate electrical record where the completed repair requires one. ## Electrical fault-finding questions What to know before arranging a visit. ### What electrical faults can you investigate? The service covers faults in the fixed electrical installation, including circuits, sockets, switches, lighting and protective devices. Describe the symptom so the team can confirm the right appointment. ### What should I do if an RCD or breaker keeps tripping? Do not keep resetting it if it trips again. Leave the affected circuit or equipment off if you can do so safely and arrange for a registered electrician to investigate. ### How long does fault finding take? It varies. A visible loose connection may be found quickly, while an intermittent or concealed fault can need more testing and access. The published rate and any further scope are made clear. ### How much does electrical fault finding cost? The current hourly rate appears above. The final cost depends on the diagnostic time and access. Replacement parts and larger repairs are quoted separately unless the confirmed quote says they are included. ### Do you repair faulty appliances? This page covers the property's fixed electrical installation. Appliance repair is separate, although testing may show that a particular appliance is causing a circuit to trip. ### Will walls or floors need to be opened? Not automatically. Testing starts with safe, non-destructive access. If concealed wiring needs access, the electrician explains why and agrees the next step before anything is opened. ### Will I receive a certificate? That depends on the repair. The electrician should provide the electrical certificate or test record required for the work that is completed. ### Do you cover my postcode?
