“Fantastic service from Innes. Hired to fit a new extractor fan in the bathroom. He walked me through the options available and what he would recommend. On the install day he arrived on time and did a very professional install in the loft.”

FAQs

Common Questions

Circuits trip for several reasons — overloading (too many appliances), a faulty appliance causing an earth leakage, a genuine wiring fault, or a degraded RCD. We systematically test each possibility to find the root cause. Don't just keep resetting the trip — contact us to diagnose the underlying issue.

Yes — intermittent faults are often the hardest to diagnose but we're experienced in tracking them down. Using insulation resistance testing, thermal imaging and load testing we can identify degraded wiring or connections that fail under certain conditions even when they appear fine at rest.

An insulation resistance test applies a high DC voltage to wiring to check the quality of the insulation. Degraded insulation — common in older Edinburgh properties — shows up as low resistance readings. This helps identify wiring that may be unsafe but hasn't yet caused a visible fault.

Yes — a pre-purchase electrical survey is a worthwhile investment, especially for older Edinburgh properties. We carry out a thorough assessment of the visible wiring, consumer unit and circuits, and report on any faults, risks or work likely to be required. This can save significant costs after completion.

Yes — thermal imaging cameras reveal hot spots in electrical installations invisible to the naked eye, including overloaded circuits, loose connections and failing components. This is particularly effective in commercial Edinburgh properties and during periodic inspections.
