All businesses in England have until the end of the month to sign up to the government's free Covid-19 workplace testing programme.
Businesses of all sizes, including those with fewer than 50 employees, can now register to order free lateral flow tests for their employees which detect coronavirus in under 30 minutes.
Companies have until 31 March to register for the workplace testing scheme, which will remain free until the end of June.
Health Secretary Matt Hancock said: "Regular workplace testing is a vital part of our route back to normal life, which is why I'm very pleased that we're now expanding our offer of free workplace testing to businesses of all sizes, including SMEs.
"These rapid tests will allows positive cases of Covid-19 to be caught quickly, which is crucial in helping businesses protect their workplaces and employees as we cautiously lift restrictions. I urge all businesses to register their interest in the programme before 31 March to help break chains of transmission and keep people safe."
