The company says it has received positive feedback from employees.
It has also built its own laboratory in Manchester, which will provide supplemental testing capacity to what the Government is already offering.
There has been a coronavirus outbreak this week at an Amazon warehouse in the West Midlands.
At least eight workers have tested positive at the retail giant’s Coventry facility.
Amazon are testing workers at the site and the GMB union has requested risk assessments are carried out.
Amazon issued a response saying safety was its top priority and since March it has put in an additional 150 significant process changes including the provision of masks and additional cleaning to ensure the health and safety of its teams.
"We firmly believe that if every person, including people with no symptoms, could be tested regularly, it would make a huge difference in how we are all fighting this virus.
“These are the actions of a company taking responsibility for the safety of its employees," it said.
