Some critical workers, however, are exempt from the requirement to self-isolate even when 'pinged' by the app, as long as they are fully vaccinated.
This is part of the Government's framework for exemption for some critical workers employed in a number of key industries to prevent serious disruption to vital public services.

The NHS Covid app was created to help in the test and trace efforts in managing the pandemic by reducing Covid infection rates.
It works by notifying people if they have come into close contact with someone who has tested positive for the virus and asks them to self-isolate.
The app uses Bluetooth to detect the distance between users and the duration of time spent in the possible exposure zone.

Double-vaccinated frontline NHS and social care staff in England who have been told to self-isolate will also be permitted to attend work in exceptional circumstances.
This will include staff who have been contacted as a ‘close contact’ by NHS Test and Trace, or advised to self-isolate by the NHS COVID-19 app, in a bid to alleviate pressure on NHS and social care services.
The following are the sectors who may be exempt from Covid isolation, with the Government expected to add more in due course.
They are:
Border control
Clinical consumable supplies
Civil nuclear
Digital infrastructure
Emergency services
Essential defence outputs
Energy
Essential transport
Essential chemicals
Food production and supply
Local government
Medicines
Medical devices
Veterinary medicines
Water
Waste

Hide AdIt is not a legal requirement to self isolate and get a test if you are told to do so via the NHS Covid-19 app when you have been in close contact with someone.
However, the government advice is that you should self-isolate for the full period, even if you display no symptoms and even if you test negative.
If symptoms are developed during the 10-day period, you should use the symptom checker in the app to find out if it could be coronavirus.
If the app confirms you may have coronavirus, you will be directed to a website where you can book a test.
