Social distancing rules are to be eased in England from July 4, meaning pubs, restaurants, hotels and hairdressers will be able to reopen.
Prime Minister Boris Johnson said people should remain 2m apart where possible but a "one metre plus" rule will be introduced.
Two households in England will also be able to meet indoors and stay overnight - with social distancing.
The prime minister warned that all the steps were "reversible".
Welsh health minister Vaughan Gething says the Welsh Government will continue to proceed cautiously on lifting lockdown restrictions, despite the PM's announcement. Non-essential shops were allowed to open from Monday of this week.
Meanwhile, in Scotland, Education Secretary John Swinney announced schools will reopen full time from August 11, subject to safe Covid levels.
Colin Borland, FSB’s director of devolved nations said: “The Education Secretary has made the right call by ensuring that schools will offer full-time education after the summer holidays. Employers and working parents will breathe a sigh of relief, given the significant economic consequences and practical difficulties of a part-time school system.
“The small business community would urge the Scottish Government to use this momentum and back day nurseries and other childcare providers so they can also open full-time on August 11, or earlier, as recommended in our recent FSB report.”
