New ‘Grandfathering rights’ legislation signed into law

Published on: 14 December 2022


The Merchant Shipping (Safety Standards for Passenger Ships on Domestic Voyages) (Miscellaneous Amendments) Regulations 2022 (“Grandfather Rights”) were signed by the Minister on the 7 December and will come into force on 29 December 2022. The two year phase-in period will run from that date, which means that operators will need to bring relevant vessels into compliance by the first survey from 29 December 2024.

In conjunction with the regulations being signed into law the MCA has released the following documents with guidance on the changes:
