Fault diagnosis
Evidence-led checks of supply loss, MCB, RCBO and RCD tripping, intermittent faults and connected equipment.

Electrical Maintenance & Reactive Call-outs
Commercial electrical maintenance and fault finding for operational buildings. We investigate the electrical path, make the situation safe and complete the right repair.
Maintenance & response
Restore the service. Understand the failure.
For FM teams, estates managers and M&E contractors, a reactive issue needs a clear technical response: what has failed, what is affected and what can safely be returned to service.
We trace supplies, circuits, controls and connected equipment before recommending repair work. This avoids replacing parts on assumption and gives you a useful basis for follow-up.
Reactive electrical support
Six practical areas of reactive support.
Distribution & lighting
Distribution boards, protective devices, local circuits, luminaires, lighting controls and damaged accessories.
Controls & plant
Relays, contactors, timers, interlocks and the electrical side of building-services plant.
Making safe / temporary measures
Risk-led isolation, temporary arrangements and clear limits where permanent repair needs planning.
Repairs & remedial works
Agreed repairs, replacements, circuit alterations and remedial works after confirming the fault.
Reporting & planned follow-up
Findings, tests, completed work and any further maintenance, testing or specialist input.
Diagnostic method
Find the cause. Not just the symptom.
A reported fault is the starting point, not the diagnosis. We work through the electrical path to identify where the expected sequence stops.
- 01
Symptom
What is not operating, and what is the immediate impact?
- 02
Evidence
Check the supply, protection, circuit conditions and relevant controls.
- 03
Fault location
Separate the failed point from the symptoms it has created.
- 04
Repair
Agree the right repair, or make the installation safe pending follow-up.
- 05
Verification
Prove the repaired circuit or equipment operates as intended.
Clear next steps
Safe action, then useful follow-up.
- 01
Make safe / stabilise
Isolate or stabilise affected equipment where needed.
- 02
Repair & verify
Complete the agreed repair and prove the circuit or equipment operates correctly.
- 03
Record & follow up
Set out findings, completed work and any planned next action.
