About us
Fifty years of UK B2B data. Still the most accurate view of the market.
Market Location has been building and maintaining the UK’s most accurate B2B data universe since the 1970s. What started as a directory-led data business has evolved into an integrated go-to-market partner – combining a human-verified business universe, a 70-seat UK call centre, and a specialist team with real client-side GTM experience.
Our goal has always been the same: to give every UK B2B sales and marketing team the data they need to spend less time on noise and more time on the right businesses. We are also a part of the 118 Group, alongside 118 Data Resource and 118 Information.

It helps organisations protect information through appropriate controls, governance, internal audits and continual improvement. Our ISO/IEC 27001 certification demonstrates that our information security management system has been independently assessed by BSI Group against this standard. The scope of the certificate is for all companies in the 118 Group.
