The rules on self-isolation changed on Monday 16 August.
People who are double-jabbed (at least 14 days prior) or aged under 18 are no longer legally required to self-isolate if they are identified as being a close contact of a positive COVID-19 case.
People aged 18 and over and NOT double-jabbed MUST still self-isolate.
Everyone who has had close contact with someone who has tested positive MUST take a PCR test to check if they have the virus and to check for coronavirus variants.
People can order a free PCR home test online or by calling 119, or going to a test site.
Double-jabbed people who have been identified as close contacts are still at risk of being infected. They are advised to take precautions such as wearing face coverings in enclosed spaces and limit contact with anyone who is clinically extremely vulnerable.
They are not required to self-isolate while waiting for the results of the PCR test.
