Self-isolation remains an essential tool to reduce the spread of coronavirus. However, the Government recognises the impact self-isolation following a positive case contact is having on individuals, particularly those delivering critical functions. In such circumstances there are a limited number of exemptions to enable named workers to leave self-isolation under specific controls. The criteria for assessing exemptions are set out in the guidance published on GOV.UK.
In addition to the exemption for critical services, daily contact testing is also now available to frontline emergency workers. This includes the Police to mitigate against any potential disruption to key services.
