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.
It involves testing of people who do not have any symptoms of coronavirus.
Surge testing started on Monday 1 February.
Genomic sequencing means analysing the virus sample to understand how it compares with other cases.
Why the government is using surge testing
Extensive surveillance of coronavirus has identified a small number of cases of COVID-19 variants and mutations which cannot be traced back to international travel.
The government is using surge testing and genomic sequencing to:
Locations using surge testing
Surge testing is currently being carried out in specific and targeted locations within the following local authority areas:

Who should get a test
You should get a test for coronavirus if you:
You should get a test even if:
you have no symptoms of coronavirus
youve had a vaccination for coronavirus
youve tested positive for coronavirus previously (but not within the last 90 days)
If youve recently spent time within one of the areas targeted for surge testing but do not live there, you should continue to follow the national restrictions and check with your local authority whether you should get a test.
Who should not get a test
If you have tested positive 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 test positive with a PCR test, your test will be sent to a laboratory for genomic sequencing.
You must isolate with your household and follow the guidance for households with possible or confirmed coronavirus infections. 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.
Positive PCR tests from institutions within these specific locations, such as care homes, will also be sent for genomic sequencing.
If you have coronavirus symptoms
If you have coronavirus symptoms, it is important that you get a test for people with symptoms online, via the NHS COVID-19 app or by calling 119.
You must isolate with your household and follow the guidance for households with possible or confirmed coronavirus infections until you get your result.
Continue to follow national lockdown rules
If you live within one of the postcode areas on this page, the same national restrictions still apply.
You should also practise Hands. Face. Space.
If you live in an area deploying surge testing and need to leave your home because you cannot work from home, or for other essential reasons, you should get tested.
