Quantity surveyors have long been tied to cost control and budgeting.
But as the industry adapts to skills shortages, tighter margins, and complex project demands, these professionals are stepping into broader roles, ones that go far beyond crunching numbers.
In 2025, they’re not just tracking costs. They’re driving strategy.
According to IBISWorld, the UK quantity surveying market continues to grow despite sector pressures. Demand is shifting toward professionals who understand not just costs, but also risk, procurement, and stakeholder coordination. And that’s changing how the job is seen.
If you’re new to the profession or curious about what it actually involves, this guide fromThe Construction Consultants — What It Is and Why It Matters breaks down the fundamentals of quantity surveying and why it plays a critical role in every successful construction project.
Let’s look at what’s driving this change, how quantity surveyors are adapting, and why they’re becoming essential to the success of modern construction projects.
What Does a Quantity Surveyor Do in 2025?
The traditional tasks of a quantity surveyor are still essential. These foundational duties are the backbone of the profession and continue to be part of everyday work:
Prepare cost estimates
Quantity surveyors are responsible for estimating how much a construction project will cost, from materials and labor to logistics and overhead.
This includes both high-level budget planning and detailed breakdowns at every stage.
In 2025, this process is more data-driven and precise thanks to integrated cost modeling tools.
Manage budgets
Once the project is underway, QS professionals monitor spending to make sure it aligns with the approved budget.
That includes spotting overspending early and suggesting corrective actions.
With tighter financial controls in place, their role in real-time budget tracking has become even more critical.
Track financial progress
QSs ensure that cash flow stays healthy across the project lifecycle.
They review payment schedules, contractor claims, and forecast future costs based on current progress.
Financial reporting isn’t just a back-office task anymore, it’s something clients and stakeholders now expect to see clearly and often.
Handle contracts and procurement
From writing tender documents to negotiating with subcontractors and suppliers, quantity surveyors ensure the right agreements are in place.
They also review contract performance and manage changes, ensuring legal and financial risks are minimised.
RICS-accredited firms in the UK offer a good standard of reliability and compliance when it comes to professional QS procurement services.
Advise on project feasibility
Before a shovel hits the ground, QSs provide critical input on whether a project is viable.
They assess site conditions, cost implications, timelines, and market risks, helping clients avoid expensive surprises down the line.
But in 2025, that’s just the foundation. The scope has grown far beyond cost control. Here’s how quantity surveyors are now shaping projects from a more strategic level:
Part of early project planning
QSs are now brought in before the design is finalised. Their insights on cost, timeline, and risk influence architectural choices, procurement models, and phasing.
This early involvement leads to fewer redesigns and better-aligned budgets.
It also means QSs have more say in shaping the project’s goals and scope, not just responding to them.
Helping shape client decisions
Clients rely on quantity surveyors not just for pricing, but for guidance.
Whether it’s whether to phase construction, switch to a different structural system, or defer parts of a project, QS professionals help clients weigh trade-offs.
This makes them trusted advisors, not just technical experts.
Monitoring market risks
Inflation, labor shortages, and supply chain disruptions can derail a project and in 2025, they’re more common than ever.
Quantity surveyors now track construction market trends and integrate risk forecasting into their recommendations.
This helps clients and project teams plan for uncertainty, not react to it.
Leading procurement strategy
Procurement is now a long-term strategy, not a one-off task.
QSs develop sourcing plans, evaluate supplier risk, and manage competitive bidding processes.
They’re expected to understand not only pricing but also delivery timelines, supplier performance, and global logistics.
Using data for forecasting and planning
Cost forecasting used to be based on historical data and intuition.
In 2025, it’s done using integrated digital tools that analyze trends, performance metrics, and real-time site data.
QSs are using this information to predict bottlenecks, adjust budgets dynamically, and improve overall project efficiency.
The Numbers Reflect the Shift
According to Statista, the number of quantity surveyors in the UK has grown consistently over the past decade, showing how demand for the profession is rising — even as automation enters the picture. This rise isn’t just about filling traditional roles. It’s about expanding the scope of what QS professionals do.
As more firms recognise the strategic value of having a skilled QS on the team early, they’re integrating them more deeply into every phase of project delivery.
If you’re exploring this as a career path, both RICS and the National Careers Service offer a solid breakdown of the routes into the profession, including qualifications and salary expectations.
Why Is the Role Evolving?
1. Skills Shortages Are Redrawing Team Dynamics
The UK construction sector is still short on skilled professionals.
As of 2024, the gap in project managers, estimators, and technical experts has widened. That means quantity surveyors are being asked to step into roles once handled by other departments. They’re handling risk plans, procurement decisions, and even stakeholder negotiations. This shift isn’t temporary; it’s part of a larger structural change.
2. More Data, More Responsibility
Construction firms are collecting more data than ever, from BIM models to supply chain dashboards. Quantity surveyors are the ones translating this data into action. Whether it’s flagging cost overruns early or adjusting for material shortages, their input now drives strategic decisions.
And because they’re trained to see both the big picture and the financial details, they’re becoming key voices in planning rooms.
3. Cost Pressure Is Forcing Smarter Spending
Every stakeholder, from clients to contractors, wants more value. Quantity surveyors are the ones mapping that value. They’re not just choosing the cheapest materials; they’re balancing cost, quality, and lifecycle impact.
That’s one reason quantity surveyors are some of the most in-demand hires for 2025. Their ability to link money to project outcomes is a rare skill, and companies are paying attention.
How They’re Becoming Strategic Powerhouses
They’re Leading the Early-Stage Planning
Most successful projects in 2025 now include a quantity surveyor from day one. Their input helps set realistic budgets and timelines, reducing late-stage revisions and disputes. When they’re involved early, risks get flagged sooner and costs stay under control.
At The Construction Consultants, quantity surveyors work closely with planners and designers from the first meeting. That integrated approach is becoming more common, especially on large-scale developments.
They’re Shaping Procurement Strategy
Procurement isn’t just about finding a supplier anymore. It’s about understanding lead times, geopolitical risks, and supplier reliability. Quantity surveyors are taking the lead on procurement planning — using both market data and past performance to inform supplier choices.
It’s a role shift, but one that fits their analytical mindset.
They’re Advising Clients Beyond Cost
Clients used to rely on architects and engineers for design decisions.
Now, they’re calling their QS for input on phasing, material choices, and even cash flow planning.
The result? Better-informed decisions. Less waste. Fewer delays.
Technology Is Part of the Shift — But Not the Whole Story
Digital tools like BIM, 5D cost modeling, and cloud-based project management platforms are part of what’s enabling quantity surveyors to take on more. These tools let them access real-time updates, model different outcomes, and communicate with teams instantly.
But it’s not just about tech. It’s about how they use it.
The QS who adds value in 2025 is the one who understands not just what the data says — but what it means.
What Kind of QS Is in Demand Right Now?
There’s a clear shift in hiring priorities. Companies aren’t just looking for people who can draw up a bill of quantities. They’re looking for:
- Strong communication skills
- Commercial awareness
- Tech literacy
- Strategic thinking
Roles for quantity surveyors who can manage large frameworks or work in infrastructure are growing fastest. Firms want people who can manage complexity, not just costs.
And it’s not just large projects. Even smaller firms are seeing the value in bringing strategic QS professionals into early planning stages.
Real-World Examples: How Quantity Surveyors Are Leading
Infrastructure Projects
In large-scale public works like rail and roads, QS teams are helping manage massive supplier networks, ensuring government budgets are respected and taxpayer money is used efficiently.
They’re also contributing to social value metrics, ensuring that projects deliver more than just structures.
Commercial Developments
On office builds and retail developments, they’re helping clients make long-term decisions about sustainability and maintenance costs, not just upfront capital expenditure.
It’s a shift from “how much will this cost?” to “what’s the total value we’ll get out of this?”
Why This Shift Matters to the Industry
When quantity surveyors take on strategic roles, projects are:
- Better planned
- More efficient
- Less likely to go over budget
- More responsive to risks
It’s a win for clients, contractors, and the public.
And as The Construction Consultants’ project portfolio shows, successful projects often have one thing in common: early, consistent involvement from commercial professionals.
The Future of the Role
Looking ahead, we’ll likely see:
- More hybrid QS roles (e.g. QS/Project Manager)
- Greater involvement in ESG metrics and reporting
- Expansion into international procurement and compliance
Training is adapting too. RICS and university programs are starting to include more content on strategy, data, and communication, reflecting the wider scope of the job.
For firms that want to stay competitive, supporting this evolution is critical.
Challenges Still Remain
This shift doesn’t come without pressure. Many QS professionals report:
- Higher expectations with little extra support
- Gaps in tech training
- Burnout from juggling multiple strategic roles
Firms that want to get the best from their quantity surveyors need to invest in proper support. That means better systems, smarter team structures, and more room for QSs to focus on what they do best.
As this article from The Construction Consultants explains, having the right construction consultants in place, including skilled QSs with the right backing, can help avoid costly mistakes and delays. It’s not just about hiring more people; it’s about making sure the right roles are in place from the start.
