Summary of the contracting process

The Crown Estate, a central government public authority located in London, has recently concluded the procurement process for its "Ecological Surveys Advisor ITT." This initiative focuses on supporting ecological surveys required for the next offshore wind leasing round. The open procedure tender, completed in October 2025, attracted participation from multiple bidders. Tetra Tech Limited, a large enterprise based in Leeds, has been awarded the contract to provide services, spanning from survey design to marine consenting advice. The contract is set to run from 29th October 2025 for an initial period of 36 months, with a possible extension for an additional year, resulting in a contract value of £3,000,000 by gross amount. This procurement falls under the service industry category and involves environmental engineering consultancy and marine survey services.

This contract presents lucrative opportunities for businesses specializing in environmental engineering and marine surveys. By securing a framework agreement, The Crown Estate aims to streamline future ecological service requirements through structured call-offs, thus reducing the need for individual tenders. This approach offers stability and growth for Tetra Tech Limited and similarly positioned large enterprises in this sector. Additionally, the focus on offshore wind projects could appeal to companies with expertise in renewable energy-related environmental assessments, enabling them to contribute to and benefit from the burgeoning offshore wind industry in the UK. The contract's framework nature is ideal for businesses seeking long-term, strategic partnerships with central government entities.
