International cruises will be able to start again from England from August 2 after a 16-month break.
People arriving at UK ports who have been fully vaccinated in the US and the EU will also not have to quarantine, the UK government said, BBC reported.
It is part of a plan to relax isolation rules for US and EU arrivals in the UK.
An industry body said travel agencies, hotels, tour guides, port operators and other firms would benefit from cruises restarting.
Domestic cruises have been allowed to run from May but international cruises have been prohibited.
