About our data

Our database covers 1,486,280 trading UK businesses in more than 2,000 business categories. This page explains what's in it, how it's kept up to date and how to use it within the law.

What a record contains

A record can include the business name, postal address and postcode, telephone number, a named contact and their job title, email addresses, website, business category and employee size band. Not every record has every field. Your free count shows exactly what's available for the businesses you want.

How the data is kept up to date

Records are checked by telephone researchers every day, and businesses that have closed or moved are updated or removed. Record counts on this site were last updated in November 2026. We guarantee that at least 95% of the records you buy are accurate.

Using business data within the law

UK GDPR and the Privacy and Electronic Communications Regulations (PECR) allow business-to-business marketing, with some rules:

• Companies and other organisations (limited companies, LLPs, charities, public bodies): you can send marketing emails without prior consent if you identify yourself and offer an easy opt-out. Check phone numbers against the Corporate Telephone Preference Service (CTPS) before calling.
• Sole traders and partnerships are treated as individuals: you need consent before sending marketing emails or texts, and you must check numbers against the Telephone Preference Service (TPS) before calling.
• Post: you can write to any business, as long as you say who you are and honour requests to stop.
• Tell people where you got their details within one month of first using them, and keep a suppression list of anyone who asks you to stop.

For full guidance, see the Information Commissioner's Office guide to direct marketing.
