Trinity Fire & Security Systems are seeking an experienced Commercial Manager to own the commercial lifecycle and cost control of fire & security projects filme covering pre‑contract, contract execution, change management, valuations, final account, and post‑project lessons learned.

This dual role combines the strategic, client‑facing responsibilities of a Commercial Manager with the analytical, cost‑management duties of a Quantity Surveyor, ensuring profitable delivery, contract compliance, and cash certainty across a portfolio of projects (typically major projects and assistance to small works if required).

What you’ll be doing

• Lead risk identification and mitigation, interpret specifications/drawings, and select, amend, and negotiate appropriate contract forms (JCT/NEC/bespoke) to secure commercially robust terms.

• Establish and control project budgets and CVRs, manage payments and change control, and maintain all commercial registers to ensure accurate forecasting, compliance, and value protection.

• Measure and value works, reconcile costs, manage interim and final accounts, and optimise margins through productivity validation, value engineering, and procurement efficiencies.

What we’re looking for

You might already be a Commercial Manager or Quantity Surveyor – or perhaps a Fire & security professional ready to take the next step. You’ll have:

• Proven commercial/QS experience within M&E or Fire & Security, with proven success delivering profitable outcomes under JCT/NEC contracts across complex or multi-site programmes.

• A strong understanding of Commercial law and contract administration.

• Experience with CVR, cash flow, WIP, earned value, forecasting, margin management.

What Trinity Offers

• Competitive base salary.

• 23 days’ holiday, increasing with service, plus bank holidays.

• Company vehicle or car allowance.

• Employee Discount Programme – savings across 800+ retailers.

• Pension via Royal London, Life Assurance, and Employee Assistance Programme.

• Referral bonus of up to £2,000.
