NHS Covid passes are to be required in cinemas, theaters and concert halls in Wales under new government plans from November 15.
Anyone over 18 in Wales must already use an NHS Covid pass to legally enter nightclubs or large-scale events, but this must be extended next month.
But what are the pass rules in other UK countries?
As of October 1, those over 18 in Scotland need full proof of vaccination to enter nightclubs, adult entertainment venues and large-scale events.
This includes indoor events with more than 500 people, outdoor events without a seat with more than 4,000 people and any event with more than 10,000 people – as in Wales.
Northern Ireland does not have a formal passport regime for entry to the sites.
Sites have been advised to request full proof of vaccination or negative lateral flow tests, but this is not legally enforceable.
But residents of Northern Ireland can apply for a Covid status vaccination certificate online – for those who have had a dose or two.
The government has abandoned plans for passports in England, but they could still be introduced if cases increase in the winter.
You can still prove your vaccine status with a Covid Pass on the NHS app (which is different from the app that alerts you if you’ve been in close contact with someone who has tested positive).
