NHS Test and Trace

The NHS Test and Trace service ensures that anyone who develops symptoms of COVID-19 can be tested quickly. It will also help trace close recent contacts of anyone who tests positive for coronavirus and if necessary, notify them to self-isolate at home to help stop the spread of the virus.

Test and Trace app

The NHS Covid-19 contact tracing app has launched as part of the coronavirus testing and contact tracing programmes in England and Wales. It's the fastest way to see if you're at risk from coronavirus with tools including contact tracing, local area alerts and venue check-in.

Contact tracing system for Redbridge is designed to provide another layer of support to help control the COVID-19 virus. 

You may be entitled to some financial support during your self-isolation period, find out if you are eligible on our Test and Trace support payment page

We are supporting businesses through the process, if you're a business in Redbridge, find out what you need to do on our app support from businesses page.

How Test and Trace works

If you have symptoms

  1. Self-isolate for at least10 days as soon as you experience symptoms.  
  2. Order a test immediately or call 119 if you have no internet access.
  3. You will receive your results.  If you test positive you must complete your 10-day self-isolation. If your test is negative, you no longer need to isolate.
  4. Share contacts. If you test positive, the NHS Test and Trace service will contact you with instructions of how to share details of people with whom you have had close recent contact and places you have visited. 

If you have been in contact with someone who has tested positive

  1. You will be contacted by the NHS Test and Trace service that you have been in close contact with someone who has tested positive. 
  2. You will be told to begin self-isolation for 10 days from your last contact with the person who tested positive. Your household does not need to self-isolate with you if you do not have symptoms. They should take care to follow guidance on social distancing, hand washing and avoid contact with you.  

You do not need to isolate if:

  • you're fully vaccinated – this means 14 days have passed since your final dose of a COVID-19 vaccine given by the NHS
  • you're under 18 years and 6 months old
  • you're taking part or have taken part in a COVID-19 vaccine trial
  • you're not able to get vaccinated for medical reasons

Even if you do not have to self-isolate, you are strongly advised to:

  • You are fully vaccinated 14 days after having received two doses of an approved vaccine (such as Pfizer/BioNTech, AstraZeneca or Moderna/Spikevax) or one dose of the single-dose Janssen vaccine.

Please see information on when you do not need to self isolate. 


 3. Order a test if you develop symptoms or call 119 if you have no internet access. 

 4. If you test positive you must stay at home for at least 10 days. The service will be in touch to ask about people you have had close recent contact with.
