The EC Procurement Directive has been incorporated into UK law. It applies to contracts above certain levels:
When contract values are over the above thresholds then the tenders are subject to EU rules. These tenders must be advertised in the Official Journal of the European Union (OJEU) and follow the EU Public Sector Timescales from dispatch to OJEU.
Please see the attached documents below, which demonstrate the legal process Doncaster Council has to adhere to when advertising open and restricted tenders.
