On 6 March, the Government announced that all businesses in England, including those with fewer than 50 employees, are now able to sign up to the free coronavirus workplace testing programme to have free rapid tests.
Businesses are encouraged to register their interest by 31 March to order free lateral flow tests for their employees.
Rapid testing detects cases in under 30 minutes, meaning positive cases can isolate immediately, breaking chains of transmission. Regular testing could be the difference between a workplace being able to stay open and operational, or needing to close due to a coronavirus outbreak.
