The UK Government is offering free rapid lateral flow tests to UK employers who register on or before March 31st 2021.
The test kits will be available until June 30th for twice-weekly workplace tests.
The scheme has been extended to all employers whose business is registered in England and whose employees cannot work from home.
Previously, only employers with more than 50 employees were eligible for free test kits.
The aim of the campaign is to quickly detect asymptomatic cases thereby preventing workplace outbreaks.
The tests deliver results in less than 30 minutes.
However, the UK Government is still advising office workers to work from home where they can.
At March 21st, 28 million UK adults (over half of the UK adult population) had received their first Covid vaccine jab and 2.3 million had received their second dose.
The current vaccine rollout target is for all UK adults to have received their first dose by the end of July.
