Senior Leadership for Complex Projects
JSA is a project management and cost consultancy built on a simple belief; complex projects require clarity, control and experienced leadership through to completion.
Our Story
Great projects start with an idea - and we love helping bring them to life.
At Stockwin Associates, we’re passionate about creating places that make a difference: spaces where people learn, work, connect and thrive. Whether we’re helping breathe new life into a historic building, improve a healthcare environment or shape a new community facility, we enjoy turning complex challenges into practical ways forward.
For us, good project management is as much about people as programmes and budgets. We enjoy building strong working relationships, bringing different perspectives together and helping project teams do their best work.
JSA was founded by Jon Stockwin in 2023, to offer clients direct access to senior expertise - without unnecessary layers or complexity.
What began as supporting the delivery of challenging construction projects, JSA has grown into a consultancy trusted to step in where others step back. We are often engaged on long-running, stalled or high-risk projects that require decisive leadership and practical problem solving. Today JSA works across various sectors, delivering projects that serve clients, communities and sustainable outcomes.
Our Approach
Our consultancy is grounded in three core principles.
Control
Bringing order, oversight and certainty to complex projects through strong governance, leadership and decision-making.
Value
Maximising efficiency, quality and long-term impact - ensuring every decision supports measurable outcomes for clients and communities.
Risk
Identifying and managing challenges early, reducing exposure and protecting project success.

Jon started his career as an Analyst in the energy and logistics sector before moving into Project Management. After moving into the construction industry 20 years ago, Jon has delivered more than £1 billion worth of construction projects across a wide range of sectors, including higher education, defence, leisure, healthcare, local government, emergency services, commercial, and community-led developments.
Appointed to recover a delayed project, JSA led the transformation of an outdated facility into a fully serviced chemistry laboratory - re-establishing the team, securing approvals, and delivering on time and within budget in a live teaching environment.
