About the buyer

Smaller orders are handled by delegated purchasing officers across the organisation. Larger opportunities are scrutinised by a Business Investment Group before going to a Portfolio Scrutiny Committee.

Over the past 5 years, most of the Office for National Statistics's contract awards have been in IT services, software and information systems and office and computing equipment.
