Pre-Construction Quantity Surveyor

Pre-Construction Quantity Surveyor – M&E & Fire Protection

About Harmony Fire

Since 2017, Harmony Fire has become the 72nd fastest-growing company in Europe, but we’re aiming even higher.

Our mission is simple: to protect more people, increase our social impact, and provide greater progression opportunities for our team. By delivering the highest-quality service, we make the UK safer, one home at a time.

We do this through our unique methodology:

• Think – Creating smarter solutions for a safer, more risk-averse future
• Protect – Applying knowledge to build safer environments
• Sustain – Building long-term partnerships based on trust and value

The Role

As a Pre-Construction Quantity Surveyor, you will ensure the commercial and contractual success of Harmony’s fire protection and wider M&E projects. You’ll take ownership of cost planning, contract management, and commercial reporting during the pre-construction phase, while also supporting the delivery team through seamless project handovers.

This is a role for a QS who understands the technical demands of M&E and fire safety packages — from sprinkler systems and alarms to integrated mechanical and electrical works — and can balance that with sharp commercial judgement.

Key Responsibilities

• Develop and manage detailed M&E cost plans covering labour, plant, and specialist fire protection materials
• Evaluate and compare M&E subcontractor quotations, challenging assumptions and ensuring compliance with specifications
• Draft, review, and administer contracts (JCT/NEC) with a focus on M&E scope and deliverables
• Manage valuations, variations, change control, and applications for payment throughout pre-construction and handover
• Provide commercial risk assessments specific to M&E packages (supply chain dependencies, compliance standards, design changes)
• Support technical design reviews, ensuring cost implications are captured and communicated
• Collaborate with designers, engineers, and project managers to produce commercially viable solutions
• Lead commercial input during client meetings, progress reviews, and contract negotiations
• Mentor junior team members (estimators/surveyors), embedding Harmony’s methodology
• Deputise for the Pre-Construction Manager when required

What We’re Looking For

• Proven experience as a QS within M&E, building services, or fire protection (essential)
• Strong knowledge of M&E systems, fire safety compliance, and buildability considerations
• Solid understanding of contract law and frameworks (NEC, JCT)
• Strong financial and analytical skills with the ability to track and report on M&E project costs
• Confident negotiator who can manage complex subcontractor packages and justify commercial positions
• Detail-driven, with a proactive approach to risk and problem solving
• Ambitious and resilient, with the drive to grow into more senior pre-construction leadership
