The Orange Partnership

Cost assurance, commercial performance and contract transparency

Helping clients strengthen commercial governance, improve cost assurance and enhance confidence in programme delivery through a unique combination of forensic accountancy, audit expertise and construction commercial knowledge.

Maximise value from major programmes and open-book contracts

Organisations delivering large-scale infrastructure, capital and operational programmes face increasing pressure to improve cost transparency, manage commercial risk and demonstrate effective stewardship of project expenditure. With over 20 years of experience supporting some of the UK's largest and most complex reimbursable and open-book contracts, The Orange Partnership, now part of Deloitte UK, helps organisations improve visibility, reduce risk and drive better commercial outcomes.

Major projects generate vast volumes of commercial, contractual and financial data. Maintaining confidence in contractor charging, ensuring compliance with complex contractual arrangements and identifying emerging risks can be increasingly difficult as programmes scale.

Without effective assurance and governance, organisations may face:

  • Reduced visibility of project costs
  • Weakened commercial controls
  • Increased risk of overcharging and contractual disputes
  • Challenges in demonstrating value for money
  • Limited insight into emerging commercial risks

We help clients address these challenges through targeted assurance, commercial governance and risk-based oversight.
