Before you can develop an offshore wind project, you must secure seabed rights from either The Crown Estate (England, Wales, Northern Ireland) or Crown Estate Scotland. Without a seabed lease, you cannot proceed with planning consents, grid connections, or construction.

Understanding the payment structure

Offshore wind developers face two payment phases: annual option fees during pre-development, followed by operational rent once the wind farm begins generating electricity.

Navigating the leasing process

Securing seabed rights involves a competitive multi-stage process from initial Pre-Qualification through to full operational lease. The journey can take several years and requires coordination with planning consent and grid connection timelines.

What happens after securing seabed rights

Once you have an Agreement for Lease, you can proceed with environmental surveys, planning consent applications (Development Consent Order for projects over 100 MW), and grid connection agreements. Final Investment Decision and construction commencement trigger conversion to the full operational lease lasting up to 60 years.
