We are making some changes so it is easier to take part in the survey.
You will post your samples to us, rather than having face-to-face appointments at your home, for greater flexibility.
You will still answer survey questions, but you can respond online or on the phone.
The world-leading survey provides valuable information to answer important questions about how coronavirus (COVID-19) is changing across the population. As we learn to live with COVID-19, the government is clear that ongoing surveillance is critical to manage the virus, react to any emerging variants and monitor how vaccinations and previous infections affect our risk of getting COVID-19 in the future.Back to table of contents
You will receive a letter from the Office for National Statistics (ONS) if you are invited to register and take part. We are not accepting new registrations right now, but we may contact you in the future.
If you are already taking part in the CIS, we will continue to update you about the study by letter or email. It is helpful if you can keep a record of your unique participant ID, which appears on letters and emails.Back to table of contents
The ONS is responsible for running the survey, working closely with the University of Oxford who is the sponsor for the survey, managing the Research Ethics Committee approvals and providing scientific oversight. The Research Ethics Committees are entirely independent groups, which review research proposals and give an opinion about whether the research is ethical.Back to table of contents
The changes to the survey will give you greater flexibility around when you take your samples and answer the questionnaire. In future, you will not need to wait for a study worker to come and visit you, and you can post your samples back to us at your convenience within your allocated testing window.Back to table of contents
You will receive a letter or email from us (ONS and University of Oxford) telling you the days in which your tests should be completed, called your “testing window”. Your swab kit will arrive in the post (as well as a blood kit if you are taking part in blood testing) and you will need to take your samples, post them in your nearest Royal Mail priority postbox, and complete the online questionnaire within the testing window.
If you need any support with this process, please contact us by phone or email. Our contact details are in the email or letter telling you about your testing window and in the “Further help” section of this guide.Back to table of contents
We use testing windows to make sure that we sample a wide range of representative people across the UK every week and tests are evenly spread to give us the most accurate picture of current infection rates.
We aim for everyone in the survey to give a sample roughly every month after they first join. If you do not take your sample and complete your questionnaire within your testing window, you will not receive a voucher for this testing window.Back to table of contents
Priority postboxes have extra or later collections than regular postboxes, which is why it is important to use them to return your samples.Back to table of contents
If you cannot get to the priority postbox yourself, you can ask someone else to post the samples for you.Back to table of contents
You do not need to pay for postage. All test kits are sent with pre-paid packaging.Back to table of contents
If you cannot reach a priority postbox yourself and have no-one you can ask to help, a courier service is available. Instructions on how to organise this are in your letter.Back to table of contents
If you cannot use a computer to complete your questionnaire, you can do it over the phone. Details of how to contact us to do this are in your letter.Back to table of contents
For every testing window completed, each person in the household will receive a £20 voucher, if they wish to accept it. A completed testing window means you have provided and posted your samples and completed the questionnaire.Back to table of contents
At present, there are no plans to change where you can spend your vouchers. A full list of online and in-store retailers can be found at ons.gov.uk/cis. Remember that the electronic vouchers last for three months and then expireBack to table of contents
