Business Lists

Selection criteria

As one of the UK's leading suppliers of high quality and reliable business data, we offer a comprehensive range of business data information. Choose any combination of relevant business list selections from the following:

Type of business or organisation
Size of business or organisation
Job function
Site status
Premises type
Public sector
Medical data
Other criteria

Raw data for our business lists comes typically from public domain sources such as Companies House and business directories. Detailed information is then gathered daily, through ongoing telephone validation carried out by trained researchers. They verify the company information (size, business activity, site status etc) and names, job titles and job functions of key senior contacts. Where actual turnover and employee size are not known, a profiled or "modelled" value is applied.

Re-verification is carried out at pre-determined regular intervals, depending on the size of the company. The largest are contacted every three months.

Updates and cleaning (gone-aways and notified changes of address/contact name) are carried out constantly.


We offer a 100% guarantee on all postal and telemarketing data with no threshold, and 95% deliverability on all email data.


Business list rates vary, depending on the volume, the type of data and the usage you require. The cost options for your data will be clearly outlined in your data proposal.
