We diagnose electrical faults where suitable, but NealAutos UK does not offer wiring repairs as a standard service.
We confirm the job is safe and practical before we book it.
Mobile mechanic work depends on the location, access around the vehicle, ground conditions, weather and the repair itself. Tell us where the vehicle is and what you need done; we will confirm whether it is suitable.
