Jon Sime

Jon is one of the founding directors at Walker Sime. While watching hapless Poms struggling to master the art of surfing on Bondi Beach in Australia, he met Derek and 10 years later the Company was formed.

He is responsible for managing the Commercial Management Service offering which includes Quantity Surveyors, Commercial Managers, and Claims/Delay Consultants, within the Infrastructure, Utilities, Rail, Power and Energy sectors.

Jon is very strategic in helping Clients develop the necessary commercial solutions to manage risk and maximize returns.


Jon loves watching all sports, particularly football, and also enjoys golfing, skiing and playing guitar, although not at the same time. He is married with two children and lives in Manchester.


Jon has worked in London, Sydney and across the North West. Initially Jon qualified as a Quantity Surveyor while working for a large PQS firm in London, then went on to work as a Commercial Director within a Contracting organization, before becoming a Claims Consultant. Eventually Jon brought all his experience together and set up Walker Sime with Derek in 1999.

Jon loves being directly involved with Clients, and managing commercial teams to find solutions to contractual and commercial problems. | 0161 872 9955
