Unpublished data stays unknown. Awarded suppliers are winners, not all bidders.

What is being bought
The Crown Estate (TCE) is seeking to establish a contract with a single supplier to provide specific services to support the delivery of Ecological surveys for the next offshore wind leasing round. The purpose of this tender is to provide TCE with an efficient way to call off future requirements for Ecological services. This will avoid individual tenders being issued as required and Tenderers having to invest time in bidding for multiple tenders. When the contract is let to a single supplier, Individual Work Orders will be issued using structured call offs, with each detailing the specific scope, activities, deliverables and timelines.
