Ipsos is commissioned by a wide range of organisations to carry out a large number of research projects each year. In conducting this research we make contact with millions of people each year and rely on the goodwill and voluntary cooperation of individuals in order to carry out the research across the world.

If we have called you, and you wish to prevent any further calls, please email UK Telephone Respondent Requests providing your contact telephone number. Please note:  in order to do this, we will need to store your number on a database to ensure we can exclude your number on future studies, as they are generated at random for many studies, and so to avoid any chance of us re-contacting you, we need to retain your number. We absolutely guarantee that our "Do not call" database will not be disclosed to any third party, nor will it be used for any other purpose, and will only contain the contact details that you provide to Ipsos so that we can comply with your wish to not contact you in the future.

Requests will normally be processed within one working day, but on occasion it can take two working days to process.

We currently have a small telephone centre in Northern Ireland where we conduct interviews for local clients.  We use the following telephone numbers:

  • 028 9620 5108
  • 028 9620 5128
  • 028 9620 5134

Where did you get my telephone number from?

On some studies your contact details will have been provided by the organisation that has commissioned the research. However, on most research conducted via the telephone, telephone numbers are generated using a process known as "random digit dialling". This involves generating a phone number by randomly adding the last set of digits to known valid area codes and exchange numbers to produce a telephone number. Other than the approximate geographical location of this number based on the area code and telephone exchange, nothing else is known about the number. It may be a public telephone box, business, fax machine etc. We do this to ensure we reach a genuine cross section of the public.


My telephone number is registered with the Telephone Preference Service (TPS) and / or BT Privacy service to stop cold calls so why are you calling me?

It is a legal requirement under The Privacy and Electronic Communications Regulations (EC Directive) Regulations 2003 for companies or organisations that are making unsolicited calls (cold calling) for sales or marketing purposes to filter those calls against the TPS lists. There are no legal or regulatory requirements to filter unsolicited calls made for research purposes against the TPS. Our call to your telephone number was NOT intended to sell, market or provide any details for any goods or services in any way. Our call would have been made to request your participation in a genuine research study. In conducting these studies we are required to ensure that the individuals who take part are fully representative of the target audience being researched. To exclude individuals with TPS registered telephone numbers could bias the results. It would also deny you the opportunity of participating in this research, the results of which may impact policies or services you use. We have found that a similar number of individuals who have TPS registered numbers take part in our studies compared to those who are not TPS registered.


Why is my opinion important?

We work for a wide range of clients including:

International, European and UK national, regional and local government bodies: Who use the research to gain accurate and up to date information which is used for future planning and to shape future policy decisions.

Major Charities: Commission research in their areas of interest to better understand peoples views and experiences.

Universities and colleges: Conduct academic research in association with Ipsos .

Private sector organisations: Use research to understand how their organisations, products or services are perceived for example.


How do I know the information I supply is safe?

Our interviewers will provide details of what the research study is about and how the information you supply will be used in that research and you are perfectly entitled not to answer any question you are not comfortable with or to change your mind and not take part at any time during the interview.
