What is Plus Four Market Research Limited?

We are an independent, UK-based full-service market research agency providing both qualitative and quantitative research across a wide range of sectors throughout the UK and Europe. Established in 1970, we have successfully delivered more than 23,000 B2B and Consumer research projects, offering invaluable experience, flexibility, and reliability to every client.

Our team of skilled research professionals takes a hands-on, collaborative approach to every project. A senior researcher will be assigned to you and will guide your study from design and methodology through fieldwork (online and offline), moderation, analysis, and reporting, ensuring continuity and consistent quality at every stage.

If you require modular support for part of your research project, the services of our specialist teams including recruitment, field services & tab, data collection, and analysis can be accessed individually, this allows you to tailor our services to your specific requirements.

Our in-house viewing facility, The Qualitative Lab, is conveniently located in Wimbledon, South West London. With excellent transport links to Central London (just 15 minutes from Waterloo), all major London airports, and local hotels, it is the ideal venue for focus groups, depth interviews (IDIs), workshops, and client meetings. The facility is fully equipped with professional hosting, audio and video recording, plus web broadcasting and streaming for remote participation. The Qualitative Lab can be hired independently or as part of a full research project. Visit www.thequalitativelab.co.uk for details.

Whether you have a clear research brief or need guidance on the best approach, our experienced team is here to help. Contact us to discuss your next market research project in the UK or Europe — and let’s turn your questions into actionable insights.
