The Qs Company

The QS Company is a specialist cost consultancy providing independent, judgement-led Development Cost Assurance™ for developers, lenders, and capital partners. We operate across the full development lifecycle, helping clients reduce cost risk, protect margin, and make confident commercial decisions from inception to completion. Most development margin is not lost in construction alone. It is lost through early optimism, design drift, opaque tendering, contractual risk crystallised at award, and undisciplined cost governance during delivery. Our work is structured around the Development Cost Assurance Framework™ — a five-stage methodology designed to provide funder-grade cost certainty and commercial control at each key decision point: • Strategic Cost Viability • Design Cost Optimisation • Market Tender Alignment • Contract & Risk Certainty • Construction Cost Governance Each stage may be instructed independently or as part of a full lifecycle appointment. Our advisory work is underpinned by deep technical delivery capability, including quantity surveying, contract administration, lender monitoring, capital allowances advisory, and dispute avoidance — always delivered in alignment with commercial outcome. We operate independently, without percentage-based incentives, and with discretion appropriate to developer, lender, and capital partner relationships. Experience includes the commercial management of over £1bn of construction cost across residential, mixed-use, and commercial developments nationwide.
