Description
About the NVQ
Plant and machinery maintenance is precise, technical work — diagnosing faults, carrying out servicing, determining whether to repair or replace components, and testing plant and machinery to confirm it’s safe and serviceable to return to work. The Level 3 NVQ Diploma in Construction Plant or Machinery Maintenance gives experienced fitters and technicians a nationally recognised way to have that competence formally assessed.
If you’re already doing this work, it turns your day-to-day workshop or site experience into formal, recognised proof of your competence — and supports your application for a Gold Skilled Worker CSCS Card.
