The government has released a list of 16 sectors where fully vaccinated workers will be exempt from self-isolation when told to quarantine after coming into close contact of someone who has tested positive for Covid-19.

The new process will allow critical workers to carry on with their jobs even if identified as a contact of a coronavirus case.

It is only intended to run until August 16, when a wider relaxation for fully vaccinated contacts is set to take effect.

Where employers believe the self-isolation of certain key employees as contacts would result in serious disruption to critical services, they have been asked to contact the relevant Government department.

Individuals identified as contacts should only attend work in “critical elements of national infrastructure” and if their absence “would be likely to lead to the loss or compromise of this infrastructure” resulting in a “major detrimental impact” on the delivery of essential services or a significant impact on national security.

Updated guidance said: “In the small number of situations where the self-isolation of close contacts would result in serious disruption to critical services, a limited number of named workers may be able to leave self-isolation under specific controls for the purpose of undertaking critical work only”.

The policy only applies to named workers if their employer has received a letter from the relevant government department.

“This is not a blanket exemption for all workers in a sector,” the guidance added.

Officials will “agree the roles and workplaces that are likely to meet the criteria” for the self-isolation exemption “on a daily basis”.

“Where a specific case meets the criteria, the employer will receive a letter from the relevant department setting out the named critical workers designated and telling them what measures they and those workers need to follow,” the guidance said.
