Telephone Interviews: Frequently Asked Questions

We are not "Opinion UK" or "Opinion Research UK" and we NEVER dial out on a mobile number. If you have been receiving nuisance calls from mobile numbers, please report to the ICO here. If you believe that someone is trying to fraudulently collect or use your information (e.g. your bank details), please report To Action Fraud here.

We sometimes send text messages from 07860 048000.

We understand that many people are reluctant to answer calls from numbers that they don't recognise, so we have prepared this FAQ page for people who receive a call from us and then search for 01792 825746, 01792 825644, 02037 409620, 02034 689946, 02039 186662, 02871 879603, 01273 806433, 01926 677554, 01483 378571, 01483 342717, 01923 884823, 01462 886375 or 02045 026876. It explains who we are, why we are calling and will hopefully answer any other questions you may have.

Why am I receiving calls from 01792 825746, 01792 825644, 02037 409620, 02034 689946, 02039 186662, 02871 879603, 01273 806433, 01926 677554, 01483 378571, 01483 342717, 01923 884823, 01462 886375, 02045 026876 or texts from 07860 048000 who are you, what do you want?

This number belongs to Opinion Research Services (ORS). We are a social research practice based in the UK. If you received a call from us it is likely to be a customer satisfaction survey or other research for a police force, fire and rescue service, a local council, a housing association or other public sector organisation. It may be an invitation to participate in a consultation exercise such as a focus group.

I don't want to take part in your research, why do you keep calling me?

We hope that you find taking part in our research a rewarding process. Most people are happy to have the opportunity to make their views known but nobody is obliged to take part. Getting a high response rate to our research projects is important to us and our clients so we will try calling each number we are given a number of times. If you answer our calls we will explain the purpose of the call and if you do not wish to take part just say so, we will not pressurise you to take part and we will not call you again for this purpose. However, if you do not answer our call we will assume this is because you are not available and will in most cases try to call you again at a later time.

I'm registered with the TPS/ex-directory, you shouldn't be calling me!

Calls made for the purpose of research are exempt from TPS (Telephone Preference Service) which only applies to sales and marketing calls. Further details can be found on the TPS FAQ page from which this is an extract.

"Will registering on the TPS stop market research calls?

No, market research calls are not covered in the Privacy and Electronic Communications (EC Directive) Regulations 2003 therefore companies conducting these types of calls are still allowed to call a TPS registered number. If you do not want to receive such calls, inform the caller to remove your details from their call lists."

The numbers we call are either from client supplied databases, randomly generated or from commercial sources of numbers who have consented to receive this type of call. We do therefore include ex-directory numbers in our samples and no regulations prohibit this.

Where did you get my number?

The phone numbers we use are either provided to us by our clients, for example, if you have recently had dealings with your police force, housing association, local council, etc. they may have informed you that your contact details might be passed to us (or a carefully selected research practice)to do a follow-up satisfaction? survey. Other phone numbers are either purchased from commercially available sources or randomly generated.

Do you make silent calls?

We do not make silent calls. Some call centres use a technology called predictive dialling where calls are placed by a computer before there is an agent ready to take the calls. This can lead to people receiving silent calls. We understand this can be irritating so we do not do this; no call is placed until an interviewer is ready to speak.

You called me at 8:30 in the evening, couldn't you call at a more sociable time?

We generally make our calls from 2pm-9pm on weekdays and 10am-6pm at weekends. We find that the best time to catch people at a convenient time is in the evening. We follow Market Research Society guidelines and never call people after 9pm at night. If you do wish to take part but we've caught you at an inconvenient time, our interviewer will be happy to book an appointment to call you back at a time of your choice.

Who regulates you?

We comply fully with regulations and guidelines from all relevant regulatory bodies including Ofcom, the MRS (Market Research Society), the IQCS (Interviewer Quality Control Scheme) and the ICO (Information Commissioner’s Office).

You called and got through to my answer-phone, why didn’t you leave a message saying what you want?

In many cases we are bound by the General Data Protection Regulation and the Data Protection Act which means we can only discuss the purpose of our call with the particular individual we are trying to contact. If we left a message on your answerphone and the message was picked up by somebody else this would be a breach of your privacy.

I don't want you to call me again, who do I call to have my number removed?

If you do not wish to take part, that is fine and we will not pressure you into doing so. Please be aware however that we run many different telephone projects at the same time and often we do not know the names of the people we are calling. If you do not wish to participate, please wait until we call you again and tell our interviewer you do not wish to participate. They will be happy to record this and we will not call you again for that project. If you do not wish to participate in any ORS research telephone projects, you can email your name and telephone number to and request that your number is excluded.

Is my data secure?

ORS has an Information Security Management System which is accredited to ISO 27001:2013. This covers the security of our IT systems, the physical security of our premises and the operational measures that are in place through policies, procedures and working practices. ORS's IT systems are also accredited under the UK Government-backed Cyber Essentials Scheme. Any new systems or software that we develop are designed with privacy in mind.

This page hasn't answered my question, how do I get in contact with you?

You can contact our main switchboard during office hours on 01792 535300 or email - please note that we run many telephone projects at the same time, so we may not be able to confirm which project you have been selected to take part in, but we will answer any other questions you may have.
