Have you been contacted by telephone by an interviewer working on behalf of TNS?

TNS has two UK call centres where we telephone respondents and ask them to participate in market research. There are no sales or marketing calls involved, your details are dealt with confidentially, and responses aggregated for further use.  


Why did we contact you?

We contact millions of people each year and rely on the goodwill of the public to carry out this important research. We will always introduce ourselves personally by name and by organisation and give you an outline of the topic we are researching. We will offer you two freephone contact numbers to verify we are who we say we are and would always be willing to contact you back at a time that is more convenient. All our interviewers undergo thorough training to ensure they know the standards we expect them to keep, in line with the Market Research Society and their Code of Conduct. Within Telephone Data Collection we also adhere to various other quality standards.  


TPS Registered?

Genuine market research calls such as these are permitted by TPS legislation as we hope to get your feedback and opinions to improve products and services.  


Where did we get your number from / ex-directory?

Occasionally our clients may pass on your telephone number so that we may contact you on their behalf, sometimes we may buy your telephone number from an external supplier but in the majority of research studies we run, telephone numbers are produced through a system called Random Digit Dialling. This system provides us with completely random telephones numbers and the only information we would gain from that number is a rough idea of the area from the dialling code used. Using this method we do contact unobtainable numbers, fax machines, business numbers, ex-directory, modems and any kind of telephone line that exists in order to ensure we are approaching a completely random sample of people to answer our research and that we are not biasing the data we collect in any way.
