Procurements started and contracts awarded under existing regulations

Existing legislation will apply to any procurements started under the old rules. All new procurements started on 24 February 2025 onwards will fall under the new legislation. The existing public procurement rules will continue to apply for contracts that are already in progress and for procurements started under the current regime.
