Why have I been contacted by telephone?

Some of our studies are conducted over the telephone. This is often because a household has taken part in the same study before and we are interested in knowing if anything has changed. Sometimes we will contact you for the first time by telephone instead of visiting your address.

We do not cold call

Before we phone you, you will have either received a letter from us about the study, or already taken part in the study with an interviewer. The interviewer will have spoken to you about being contacted again by telephone.

If you take part in a telephone interview, the number we will phone you from is +44 (0)2392 958 174. If you have a call filtering system on your telephone, please change it to accept calls from this number.

Do I need to do anything?

If you do not do anything, we will try to phone you again. We try to contact households over a two-week period so you may receive several phone calls from us. This is because once you or your household are selected, we cannot ask anyone else to take your place as this would affect our study.

Can I ring to make an appointment?

Yes, we would appreciate you making an appointment to complete the important study you have been invited to. Contact our freephone enquiry line on +44 (0)800 298 5313 to make an appointment at a time convenient to you.

Opening times are:
9am to 9pm Monday to Thursday
9am to 8pm Friday
9am to 1pm Saturday

Please note that this telephone number is different from the number we use to call you.

I’ve received a phone call late in the evening or early in the morning. Why is this?

We make phone calls from 8am to 9pm most weekdays. This is because we are trying to contact different types of households, so calling at varied times gives us the best chance to make contact. We also call during the day at the weekends for the same reason.

What will the study be about?

For more information about the different studies, go to the Find your study page to read about the study that you have been invited to take part in.

Can an interviewer visit me in person instead?

If you would like to take part face-to-face instead of completing the study by telephone, contact our freephone enquiry line on+44 (0)800 298 5313 to arrange this.

Opening times are:
9am to 9pm Monday to Thursday
9am to 8pm Friday
9am to 1pm Saturday

I have hearing and speech difficulties, can I still take part?

Yes, we provide a Next Generation Text (NGT) service to help people with hearing and speech difficulties communicate over the telephone. To use this service call (18001) 0800 298 5313.
