Where did you get my contact details from?

Your address was obtained from the Postcode Address File (PAF). The PAF contains UK addresses and is leased to ONS from the Royal Mail. The "Small Users File" is used by the ONS to draw household survey samples. This file consists of residential addresses and covers approximately 95% of the population.

Full details of the source of your contact details can be obtained by phoning 0800 085 7376 for free, or by emailing surveyfeedback@ons.gov.uk.

We will be carrying out many of our studies by telephone, instead of face-to-face. To help us do this, we sometimes obtain phone numbers from a commercially available source called Sagacity, which provides a facility to match telephone numbers against our sampled addresses. We also obtain numbers from other government departments. Full details of the source of your contact details can be obtained by phoning 0800 085 7376 for free, or by emailing surveyfeedback@ons.gov.uk.

What information do we collect about you?

Our studies may ask questions about all members of your household, and can cover a range of topics, including work, retirement, unemployment and looking after the family or home.

A researcher may observe your interaction with an interviewer on your doorstep. They may note down details about the interaction that will help us to improve our methods to ensure we are as inclusive as possible when we approach people in this way. Any outcomes from the research will not identify you and will help to improve the quality of the statistical data we collect.

Will I be identifiable in the results?

No, the information you submit will be treated as confidential as directed by the Code of Practice for Statistics. Any statistics or results produced will not identify you or anyone in your household.

Will anyone else see my answers?

The household access code is unique to your household, and only people with that code will be able to see any answers. Please keep your access code safe, and only share with people in your household. Once you have submitted a completed household study, the answers can no longer be accessed using your access code.

How will we use the information you provide?

Your responses to our studies will be used for research purposes only and will be stored separately from the personal information used to invite you to participate in this research. Your participation in this research, together with your individual responses to the questions will be kept confidential. The results of this research will be anonymous, statistical information only, and we can assure you that you will NOT be identifiable in any published results.

We can assure you that any information you provide during this research will NOT be used for marketing, nor will we sell or pass on your information to any third party.

For more information about this research, please contact the ONS Research Project team. They can be contacted by phoning 0800 085 7376 for free or by email sent to surveyfeedback@ons.gov.uk.

How long will you keep the information I provide?

The information you provide will not identify you or anyone in your household and will be deleted upon completion of the research project.

How do we ensure your personal information is held securely?

We take our responsibility very seriously to keep your personal information secure. As such we take every reasonable precaution to ensure your information is protected from loss, theft, or misuse. These precautions include appropriate physical security of our offices, controlled access to computer systems, and use of secure, encrypted internet connections when collecting personal information.

If you have a question about how we process your personal data or want to find out more about your rights under data protection legislation, please see our data protection page.


Some online studies collect information using "cookies". These are small files stored on your computer. These files are used sparingly and only for quality control, validation and, more importantly, to stop us sending you reminders for an online study you have already completed. It is possible for you to delete "cookies" or to prevent their use by adjusting the browser settings on your computer.

We also automatically capture information about your operating system, display settings and browser type to ensure that the study is delivered in a form suited to the software your computer is using. We do not capture any other information from your computer.
