Senior Estimator Water

Senior Estimator - Water & Wastewater
Fully Remote / Home-Based Permanent
Work from home. Shape critical infrastructure. Influence major capital programmes.
This is a genuinely flexible, home-based Senior Estimator role, offering the chance to play a pivotal part in delivering long-term water and wastewater infrastructure projects across the UK without the daily commute. From day one, you'll have the autonomy, trust and flexibility to manage your workload remotely, while still being closely connected to a high-performing delivery team.
The Opportunity
Across UK infrastructure, the challenge is no longer just maintenance, it's renewal, resilience and reinvention. This role sits at the heart of that mission.
You'll join a well-established water and wastewater capital delivery team, supporting major programmes designed to safeguard water supply, protect the environment and future-proof critical assets. Whether pricing single projects or framework packages, your work will directly influence commercial outcomes and long-term infrastructure performance.
This is a role for someone who wants impact, flexibility and progression, all in one.
What You'll Be Doing
As Senior Estimator, you'll be a key member of the estimating function, working closely with senior leadership and operational teams. Your responsibilities will include:
Producing accurate, timely estimates across water and wastewater capital projects
Supporting bids and live contracts with robust pricing, risk management and governance
Advising senior stakeholders on commercial risk, opportunity and strategy
Engaging with suppliers and subcontractors to build reliable cost data
Ensuring subcontractor terms align with client requirements, assessing any deviations
Managing and prioritising workloads to meet demanding programme deadlines
Influencing key stakeholders across commercial, operational and client teams
Identifying opportunities to improve estimating processes and performance
What You'll Bring
Essential experience in the water industry, ideally across both clean and wastewater
Background in estimating for capital projects or utility frameworks
Strong commercial and contractual awareness
Excellent communication, negotiation and stakeholder management skills
Confidence managing workloads in a fast-paced environment
Ability to identify improvement opportunities and drive change
Experience leading or supporting estimating teams
Degree qualification in Engineering, Quantity Surveying, Cost & Planning or similar (preferred)
Benefits
Alongside the flexibility of full-time remote working, you'll receive a comprehensive and highly competitive benefits package, including:
Company car and fuel card (EV and hybrid options available)
Salary sacrifice EV / hybrid car scheme
Private healthcare for you and your family
Healthcare Cash Plan (dental, eyecare, physiotherapy and more)
Matched or contributory pension scheme
25 days annual leave plus bank holidays
24/7 online GP service
Employee assistance programme
Retail discounts via rewards portal
Life assurance and personal accident cover
Enhanced maternity, paternity and adoption leave
Cycle to work and salary finance schemes
Referral rewards for recommending colleagues
Why This Role Stands Out
True home-based role with national project exposure
Long-term, secure workload within regulated utilities
Opportunity to influence major capital investment decisions
Strong focus on professional development and progression
Inclusive, people-first culture where expertise is valued
If you're an experienced Senior Estimator in the water sector looking for flexibility without compromising on scale, challenge or career growth, this role delivers all three.
