About us

Established in 2014, Castle Gate Commercial is part of the Castle Gate Group.

We’re passionate about PFI and we’re passionate about making things better for our clients. We dedicate ourselves to understanding where you are, what you need from us and where you need to get to. And then delivering. Whether it’s additional contract management capacity or advice on re-scoping and reducing costs, or management of a benchmarking exercise, our success is defined by your satisfaction.

Under the leadership of founding director David Johnson, Castle Gate Commercial has developed a reputation for pragmatic, commercially astute and deliverable PFI advice that produces quantifiable benefits. But don’t just believe us, read below to see what our clients say about our service.

Our guiding principles are:

  • To cut through the jargon and provide guidance that is understandable
  • To target outcomes that are deliverable, not those that look good in a report but are meaningless in practice
  • To be judged by the outcomes we agree with our clients
  • To provide a dedicated, personal service that meets expectations

Our clients say...


"The Ted Wragg Multi Academy Trust have procured Castle Gate to support improvements in the delivery of our PFI contract. The professional support and service provided has been excellent. PFI contracts are very specialist and complex in nature and require a high level of knowledge and expertise, which Castle Gate provide. They are the leaders in this field and we wouldn’t hesitate in recommending them."

Josie Medforth, Chief Operating Officer, Ted Wragg MAT

Our clients say...


"Castle Gate has provided Slough Borough Council with technical support around contract and commercial issues since 2014, in a number of areas. Their knowledge, technical skills, and approach to supplier management, is invaluable. They have a very professional approach, work very well with a variety of stakeholders, and have helped us achieve significant contract savings and ensure effective delivery of contractual requirements, particularly around the multi-school PFI contract."
