The hospitality sectors of Wales and Northern Ireland cheered after the relaxation of Covid-19 restrictions saw customers return.
And nursing home residents were expecting more visitors as limits are lifted in England next week, while Scots previously required to work from home will soon move to a hybrid working model.
Here, the PA news agency looks at the rules in each of the UK nations.
– What has changed in Wales?
Wales has completed the move to alert level zero, relaxing alert level two measures that have been in place since Boxing Day.
It means that nightclubs can reopen and the social distancing and rule of six requirements have ended.
It comes after crowds were allowed to return to outdoor sporting events since last Friday and limits on participating in outdoor activities were lifted.
But the Covid pass will still be required to enter larger outdoor events attended by more than 4,000 people, if not seated, or 10,000 people when seated.
Covid passes will still be required at all cinemas, theaters and concert halls that are currently open.
– How about Northern Ireland?
As of noon this Wednesday, the legal requirement to provide the Covid certification to enter bars, restaurants and cinemas ended.
Nightclubs can also reopen now, although vaccination certification will still be required to access these venues.
In workplaces, the requirement to take reasonable measures for social distancing of two meters has also been removed.
It follows the end last Friday of the requirement to remain seated and the limit of six per table in hospitality venues.
The limit on the number of households gathering within domestic settings has been lifted.
The required self-isolation period after a positive Covid test was also reduced last Friday, and positive cases can come out of isolation on day six as long as they have had two negative lateral flow tests, at least 24 hours apart, not before day five and day six.
Other restrictions that will remain in place for the foreseeable future include the use of face coverings.
– What has changed in England?
Plan B measures are being relaxed in England, where face coverings and Covid passes are no longer legally required.
Visitor limits on nursing homes will be lifted starting next week as the country moves toward living with the coronavirus.
From January 31, those living in care homes will be able to receive unlimited visits from family and friends, while periods of self-isolation will also be reduced, the Department of Health and Social Care said.
Guidance asking people to work from home has been lifted, and the legal requirement for people with coronavirus to self-isolate will also be allowed to end when the regulations expire on March 24.
– And in Scotland?
The closure of nightclubs, the requirement of table service in hospitality and the physical distancing of one meter in hospitality and leisure settings ended at 5 a.m. on Monday.
Attendance limits for indoor events and guidance asking people to stick to a three-household limit on indoor gatherings were also removed.
And Covid guidance that required Scots to work from home wherever possible is being abandoned in favor of hybrid working, Nicola Sturgeon announced this week.
The Prime Minister said as of January 31 that employers “should consider implementing hybrid working, following the proper guidance, with workers spending some time in the office and some time at home.”
However, he said the change was not expected to spark a “widespread return to office next week”, with the prime minister adding that, at this stage of the pandemic, a “massive return” was likely to set back progress. .
The use of face coverings in indoor public settings and on public transport will be maintained, as well as working from home whenever possible.
