Mechanical Project Manager - CAT B Fit Out
James Lewis Recruitment
Mechanical Project Manager – CAT B Fit Out (Central London)
Up to £80,000 + travel | Permanent | 2–3 days hybrid
If you’re tired of being the person who inherits problems at install stage, this is the role where you own delivery properly — from pre-start through commissioning and handover — on fast-track CAT B schemes where pace matters and good planning actually gets rewarded.
You’ll join a well-established design and build building services contractor delivering CAT B commercial fit out projects across Central London, typically up to £1.5m. This is hands-on, multi-project delivery: multiple live jobs, tight programmes, busy interfaces, and the expectation that you can keep quality and commercial control while still getting things built.
What you’ll do
-
Run projects end-to-end: pre-start, site mobilisation, delivery, commissioning and handover
-
Control programme: short-term lookaheads, progress reporting, sequencing and recovery planning
-
Own procurement and logistics: plant/material orders, deliveries, and working around site constraints
-
Manage labour and subcontractors: productivity, quality checks, coordination and output
-
Drive technical flow: submittals, RFIs, and coordination with design teams where needed
-
Lead meetings and actions: keep interfaces moving and close issues fast across trades
-
Support commercial performance: cost control and variations alongside the commercial team
-
Close out properly: snagging, handover documentation and O&M manuals to a clean finish
What you’ll need
-
Proven experience delivering CAT B commercial fit out mechanical packages in London
-
A mechanical building services background (time served or academically qualified)
-
Track record managing projects up to £1.5m in a fast-paced environment
-
Strong H&S awareness and solid site delivery best practice
-
Clear communication — able to manage multiple stakeholders and keep site aligned
Package
-
Up to £80,000 (dependent on experience)
-

2–3 days hybrid working
