IQCS is the independent, member-governed quality standard behind Britain's most credible fieldwork agencies — at home and on international projects. Every member audited annually. Every directory entry verified. Almost 50 years underpinning ISO 20252.
Five decades of fieldwork quality, written by the practitioners it applies to. Every member independently audited against it, every year. Not a badge. A standard.
Every agency in this directory has been inspected by an independent auditor against the published standard. Not self-certified. Not a paid badge. Audited, every year.
Browse the directoryThe IQCS standard is published openly. Use it to specify suppliers, audit your own practice, or simply understand what good fieldwork looks like in 2026.
Read the standardMember agencies write, review and update the IQCS standard every year. The people who deliver fieldwork are the people who define how it should be done.
How IQCS worksFrom global research organisations to boutique agencies and specialist providers across B2B, B2C, healthcare, social research and transport — every company on this list has been independently audited.
The IQCS standard covers every stage of fieldwork — from interviewer recruitment and training through briefing, quality control, back-checking and data integrity, to participant care and GDPR.
It's published openly, reviewed by our members, and freely available for any agency or research buyer to read.
