Senior Estimator
UK-Based | Remote/Hybrid/On-Site (Project-Dependent)
Sectors: Industrial, Infrastructure, Datacentres
Contract: Permanent; Freelance / Fixed-Term / Consultant considered also considered
I\’m currently working with a forward-thinking UK consultancy that\’s delivering a cutting-edge low-carbon infrastructure project – and they\’re on the lookout for a Senior Estimator to take the reins on cost planning from RIBA Stage 0 through to Stage 4. This is a critical position, focused on aligning capital investment with sustainability targets and ensuring robust financial planning across the early design and pre-construction phases.
What You\’ll Be Doing

• Own the Cost Plan: Lead and develop cost plans throughout RIBA Stages 0-4, ensuring all estimates evolve in step with the design and project requirements.
• Guide the Budget from Day One: Offer strategic cost advice from concept stage and refine it through technical design.
• Estimate with Purpose: Produce Order of Cost Estimates and detailed Elemental Cost Plans that support value engineering and funding cases.
• Embed Sustainability: Incorporate whole-life costing and low-carbon thinking into financial assessments, working closely with carbon and sustainability specialists.
• Know the Market: Stay sharp on trends in construction and energy sectors-benchmarking, inflation, material costs, and labour availability-to inform your estimates.
• Support Procurement Strategy: Help shape procurement approaches, engage with contractors early, and support tender evaluations with cost insights.
• Collaborate Across Disciplines: Be part of a multi-functional project team-planners, engineers, carbon consultants, PMs-and clearly communicate cost drivers and risks.
• Leverage the Right Tools: Use CostX, Causeway, or similar tools for digital take-offs and pricing, and ensure documentation meets industry standards (NRM1, BCIS).
• Report & Advise: Deliver regular reports outlining risks, assumptions, and mitigation strategies that keep the project on solid financial footing.

What We\’re Looking For

• Strong experience estimating for infrastructure, energy, or industrial projects
• Comfortable working across RIBA Stages 0-4
• Skilled in digital cost planning tools (CostX, Causeway, CATO, etc.)
• Solid understanding of sustainable construction and whole-life cost methodologies
• Clear communicator with the ability to work cross-functionally and explain complex cost data to various stakeholders

If you\’re a commercially savvy estimator with a passion for sustainability and a track record of delivering across early project stages, this is a fantastic opportunity to contribute to a meaningful low-carbon initiative in the UK.
