This guide explores ten of the leading market research companies in the UK, alongside practical advice on costs, how to choose the right partner, and the key questions to ask before commissioning research.

FAQs
CATI market research (Computer-Assisted Telephone Interviewing) is a quantitative research method where trained interviewers conduct structured telephone surveys using software that controls question routing, quotas and real-time data capture. It combines the consistency of a structured survey with the engagement of a live conversation, allowing interviewers to clarify questions, probe responses and ensure data quality in a way that online surveys cannot replicate.
CATI stands for Computer-Assisted Telephone Interviewing. It refers to the method of conducting telephone surveys using specialist software that guides the interviewer through the questionnaire, manages routing logic, validates responses and captures data in real time. The computer assistance distinguishes it from traditional paper-based telephone interviewing, where these tasks had to be managed manually.
Use CATI when data quality, respondent engagement or sample accuracy are more important than speed or cost. CATI is the stronger choice for complex questionnaires, hard-to-reach audiences, B2B research with senior respondents, and studies where findings need to withstand rigorous scrutiny. Online surveys are more appropriate when speed, scale or budget efficiency is the primary driver and the audience is reliably accessible through digital panels.
The three main advantages of CATI surveys are data quality, sample control and audience access. Interviewers ensure responses are complete and understood. Real-time validation prevents inconsistent data. Quota management keeps the sample representative. And telephone interviewing reaches audiences – older consumers, rural groups, senior B2B professionals, that online panels frequently under-represent.
The main limitations of CATI are cost, response rates and survey length. Trained interviewers make CATI more expensive than online alternatives. Response rates have declined as caller ID screening has become common. And survey length is constrained — most respondents will engage for fifteen to twenty minutes on the phone before completion rates deteriorate. These limitations do not undermine CATI’s value in the right context, but they make it important to use it where the benefits justify the additional investment.
Yes – CATI is often the most effective method for B2B market research. Reaching specific job roles, seniority levels or sectors through online panels is difficult, and response quality is hard to verify. Telephone interviewing reaches named individuals directly, confirms their relevance before the survey begins, and allows senior decision-makers to give considered, detailed responses in a way that online formats rarely achieve. B2B CATI requires experienced interviewers who can engage credibly with senior professionals.
Mixed-mode research combines two or more data collection methods in the same study. CATI is commonly used alongside online surveys to reach audiences that are difficult to access through digital panels — senior B2B respondents, older consumers, low-digital-access groups. Online surveys handle scale and speed. CATI provides depth and quality control. Used together, they produce a more robust and representative dataset than either method achieves alone.
