In England, you can leave self-isolation after 5 full days, as long as you test negative on day 5 and day 6. The first rapid lateral flow test must be taken no earlier than day 5 of your self-isolation period. You can then leave self-isolation on day 6 if both tests are negative and you do not have a high temperature. If either test is positive, you must continue to self-isolate until you get 2 negative rapid lateral flow tests taken on consecutive days, or you have completed 10 full days of self-isolation. If you leave isolation before the full 10 day period, you can disregard the app's countdown timer for the remaining days. It is a useful reminder to continue taking extra care during this period. You will not be notified by the app if you come into contact with anyone with COVID-19 while your countdown timer is on.
In Wales, you can leave self-isolation after 7 full days. You are strongly recommended to take a rapid lateral flow test on day 6 and day 7 to check if you are still infectious. The first rapid lateral flow test should be taken no earlier than day 6 of the self-isolation period. Tests should be taken at least 24 hours apart. If either of the rapid lateral flow tests taken on day 6 or day 7 is positive or you have a high temperature, we recommend you remain in self-isolation until you've had 2 negative rapid lateral flow test results or you have completed 10 full days of self-isolation, whichever is sooner. If you receive negative lateral flow test results on days 6 and 7 and leave self-isolation, you can disregard the app's countdown timer for the remaining days. It is, however, a useful reminder to continue taking extra care during this period. You will not receive any close contact notifications until your 10-day count down timer ends.
If you leave self-isolation before 10 full days you are strongly advised to:
limit close contact with other people outside your household, especially in crowded, enclosed or poorly ventilated spaces
wear a face covering in crowded, enclosed or poorly ventilated spaces and where you are in close contact with other people even if it is for a limited time
work from home if you can
limit contact with anyone who is at higher risk of severe illness if infected with COVID-19
follow the guidance on how to stay safe and help prevent the spread
If you test positive you'll also be contacted by the wider NHS Test and Trace or NHS Wales Test, Trace, Protect service. Contact tracers will use the date the test was taken or the date you confirm your symptoms started to calculate your isolation period.
