Businesses with more than 50 employees will now be eligible for joining the workplace testing programme for rapid Covid-19 testing.
Previously to be eligible for rapid testing, businesses needed to have more than 250 employees.
The government said it is working closely with organisations across different sectors that are vital to the running of the country and where employees cannot work from home during lockdown, from transport networks to food manufacturers, to sign up to rapid testing programmes.
Many employers have already taken up the offer of rapid, regular workforce testing, with 112 UK organisations across almost 500 sites joining government backed rapid testing.
More than 2.5 million tests have been distributed across the public and private sectors so far, and an online portal has been launched to make it even easier for business in the private sector to get involved and find out more about offering rapid testing in the workplace.
This expansion of testing will find more positive cases, keeping workers who cannot work from home unknowingly passing on the virus and protecting vital public services.
Matt Hancock, health secretary said: “Employers should regularly test their staff, and this drive across government to raise awareness and encourage more businesses to introduce rapid testing for employees is incredibly important.
“We are already working with many employers to scale up workforce testing, spanning the food industry, retail sector, transport network, and across the public sector too. I strongly urge businesses and employees across the country to take up this offer of rapid testing to help stop this virus spreading further.”
