Surge testing for new coronavirus (COVID-19) variants

How ‘surge testing’ and genomic sequencing are being used in locations in England where coronavirus (COVID-19) variants have been identified.

This guidance is out of date. Read about the changes to testing for coronavirus (COVID-19) in England.

Applies to England

What surge testing is

Surge testing is increased testing (including door-to-door testing in some areas) and enhanced contact tracing in specific locations in England and can look different depending on assessment of local requirements.

It involves testing of people who do not have any symptoms of COVID-19.

Tests from all of these areas are sent for genomic sequencing. Genomic sequencing is the process of testing a sample of the virus to map its genetic sequence and is used to identify variants.

If you need to take part in surge testing you will be informed by your local council.

Why the government is using surge testing

The government is using surge testing and genomic sequencing to:

  • monitor and suppress the spread of COVID-19

  • better understand new variants

Locations using surge testing

There are no current community-wide surge testing operations. Testing for variants may be happening within specific settings. If you need to take part, you will be informed by your local council.

The list is updated regularly.

Who should get a test

You should get a test for COVID-19 if you:

  • live in targeted locations within one of the areas listed on this page or are contacted by your local council

  • are in the targeted age group

If you have symptoms, self-isolate straight away and get a PCR test as soon as possible. Do not leave home, except to post a test kit or for a PCR test appointment. Check if people you live with need to self-isolate on NHS.UK.

You should get a test even if:

  • you have no symptoms of COVID-19

  • you’ve had a vaccination for COVID-19

  • you’ve tested positive for COVID-19 previously (but not within the last 90 days by a PCR test)

If you’ve recently spent time within one of the areas targeted for surge testing but do not live there, you should continue to act carefully and remain cautious and check with your local authority whether you should get a test.

Who should not get a test

If you have tested positive with a PCR test within the last 90 days, you do not need to be tested.

How to get a test

Local authorities in the postcode areas on this page are providing PCR testing to people without symptoms through extra:

  • home testing kits

  • mobile testing sites

Visit your local authority website to find out more.

What happens after your test

If you had a positive PCR test, your must self-isolate straight away to avoid spreading the infection to others.

Anyone you live with may also need to self-isolate.

Find out more about self-isolation and what to do on NHS.UK.

Public Health England will carry out enhanced tracing of close contacts of confirmed cases of the variant.

There is currently no evidence that variants cause more severe illness.

If you test negative you should continue to act carefully and remain cautious.

How to stay safe and help prevent the spread

Although most legal restrictions have been lifted at step 4, and many people have been vaccinated, it is still possible to catch and spread COVID-19, even if you are fully vaccinated.
