Cost certainty has rarely mattered more to clients. With the Autumn Budget now delivered and the Office for Budget Responsibility publishing its latest forecasts, public and private clients now have a clearer view of the backdrop for the year ahead. For organisation are now reviewing capital programmes and testing existing cost plans against current market conditions, tender pricing and programme risk.
Founded as a Quantity Surveying practice in 1970, cost consultancy remains central to our business today. As an RICS-registered consultancy, we bring a proactive, hands-on approach to every project, giving clients accurate advice and dependable financial control from the earliest feasibility stage through to final account.
Our Quantity Surveying teams are based across our Beckenham, London, Cambridge and Colchester offices, giving clients local knowledge and consistent service, backed by the wider expertise of our Project Management, Building Surveying, Employer’s Agent and Clerk of Works teams.
Recent Projects
Beaumont Rise, Islington – Residential & Supported Housing
Construction of 27 new homes across two five-storey blocks for Islington Council, comprising 10 two-bed social rent flats and 17 supported housing bedsits with ancillary accommodation. When the scheme changed contractor midway through the programme, our team provided Quantity Surveying, Employer’s Agent and Clerk of Works services to support a smooth transition, putting clear processes, communication routes and programme controls in place while keeping resident safety and minimal disruption central to every decision.
Woolwich Town Hall Repairs, Royal Borough of Greenwich – Heritage & Civic
A heritage-led refurbishment of one of the borough’s most architecturally significant civic buildings, covering major roof, facade, window, internal and building services repairs while the Town Hall remains fully operational.
We provided early-stage cost advice to shape a deliverable, fundable scope. We then translated the drawings and specification into a detailed Bill of Quantities, giving contractors a clear basis for competitive pricing and the client strong financial control after tender.
Alongside Quantity Surveying, our team provided Building Surveying, Conservation, Clerk of Works and Health & Safety services.
