Promontory is a British consultancy specialising in construction, infrastructure, energy and marine projects. We support clients throughout the project lifecycle, from tender and contract award through to completion, providing specialist contract, commercial and claims support.

Our work covers contract preparation and administration, commercial management, cost and quantum analysis, delay analysis, contractual notices and claims. We help clients manage contractual risks, protect their commercial position and address issues early, before they escalate into disputes.

Where disputes arise, we support clients through adjudication, DAAB proceedings and arbitration, providing detailed contractual analysis, delay and quantum assessments, and expert reports. We also provide independent expert witness services, including written reports and oral evidence.
