Independent Cost Assurance for Property Developers & Investors
We reduce cost risk. We protect developer margin
and investor return through foresight and disciplined cost management.
We work with property developers & capital partners
We’re independent quantity surveyors providing evidence-based advice to support sound decisions.
We work across commercial, residential, and mixed-use developments – from individual projects to multi-scheme portfolios, often in confidential or lender-sensitive environments.
Our approach puts particular focus on challenging early assumptions before further capital or design costs are committed.
Our Role
We exist to bring commercial discipline to property development
cost decision-making.
We protect margin before it is eroded, instead of explaining problems later. That means we
- Deliver robust quantity surveying and cost management services
- Apply informed and independent judgement at key decision points
- Provide funder-grade reporting and assurance.
We do not separate advice from delivery.
We are not swayed by vested interests.
We use delivery capability to inform better judgement.
How we work
Many construction projects are vulnerable to supply chain stress,
scope change, and overrun.
But it’s rare for failings to begin with a single error on site. Often they originate early on, when assumptions are accepted too easily and remain untested.
We tackle these hazards head-on. We scrutinise the quality
of early decisions and how that influences costs and outcomes.
We master the details without losing sight of the whole.
Developers, investors, and lenders all benefit.
Key Commercial Challenges
In many property developments, margin is lost when early decisions use incomplete data then remain unchallenged. Each error is compounded by the next.
No tested cost intelligence
Feasibility positions rely on optimism rather than tested cost intelligence.
Concealed until too late
Design develops beyond budget and reduced margin is hidden until too late.
Difficult to compare
Tender returns are difficult to compare – exclusions are hidden and easily missed.
The Six Stages of Our Development Cost Assurance Framework™
Our approach interrogates the project in six steps, enabling us to understand and test design criteria, construction costs, market assumptions, cost risks, and viability. The outcome is a rare clarity as to the path forward.
Commercial Assurance Pathways
Two pathways. One methodology.
For Developers
Cost certainty that protects margin and maintains commercial control from feasibility to handover.
For Lenders & Capital Providers
Independent monitoring surveying & reporting, aligned to governance and funding requirements.
Private briefings & advisory discussions
In addition to formal engagements, we periodically arrange private briefings and discussions with interested parties to explore cost risk, margin pressure, and decision-making trends across live developments.

We operate a selective practice
We are deliberately disciplined in the way we work. To protect quality and independence, we avoid booking to capacity. Many engagements are repeat instructions across multiple schemes.
We can engage with a project at any point. We seek out commissions where we can contribute to early-stage cost decisions – and materially influence commercial outcomes for the better.
We provide clarity in a complex industry
We thrive on bringing greater discipline and clarity to decisions in property development. Too often, cost risk is misunderstood or addressed too late.
We reduce risk
Our role is to reduce cost risk through structured, independent cost assurance. We have a long-term view. We prioritise reliable analysis and professional judgement over volume or convenience.
We live up to our responsibilities, willingly
As part of our wider responsibility to the industry, we have committed to a 1% giving pledge and support RICS Lionheart and the Lighthouse Construction Industry Charity, both aligned with our broader commitments as a B Corp.
Engage with The QS Company
We welcome confidential discussions.
If you are evaluating a potential project, approaching procurement, or if you require lender-grade monitoring, we can advise on what scope is appropriate – and what is not.
Engagement typically begins with a structured discussion around risk, funding, and delivery strategy. We advise candidly on whether, and how, we can add value before any commitments.
