Mechanical Site Supervisor ,South Wales | £50,000 – £60,000 | Long-Term Pipeline

Looking for a Mechanical Site Supervisor who wants stability, a strong pipeline of secured work, and projects that actually get delivered properly.


We're working with one of Wales' largest privately owned M&E contractors, a family-run group with 30+ years behind them and a reputation built on doing the job right rather than cutting corners. They've got an immediate need for a site-based Mechanical Supervisor to drive school refurbishment projects across South Wales and Cardiff, with a wider portfolio of secured work sitting behind it.


This is a priority hire. They need someone on the ground fast.


Why this one's worth a look:

  • Genuine long-term pipeline, not a 6-month panic hire dressed up as permanent
  • Family-run business with low staff turnover and a hands-on, safety-led culture
  • Mix of school refurb, commercial, healthcare and public-sector projects to keep things varied


What you'll be doing:

  • Supervising site-based mechanical works across live school refurbishment projects
  • Coordinating direct labour and subcontractors, keeping the programme on track
  • Owning H&S compliance on site and driving works through to completion


What you'll need:

  • Mechanical background with strong steel pipework / pipefitting experience
  • Proven site supervision on M&E projects (commercial or site services, not heavy industrial)
  • The communication and coordination skills to manage subbies, labour and site teams effectively


If this sounds like your kind of role, drop me a message or send your CV across.
