Business data source and verification
Business Data
You Can Trust
Business Data Prospects maintains and updates its own UK business database. Every database is freshly researched, validated and checked immediately before supply using our in-house verification process, giving organisations confidence that their B2B data is accurate, compliant and up-to-date.

How We Source and Verify Business Data
Where our business data comes from?
Business Data Prospects has built and maintained its own UK business database through more than 16 years of continuous market research, telephone verification and desk-based research.
Our in-house research team continually collects, reviews and updates business information, creating a database developed specifically for B2B sales and marketing. This ongoing process enables us to maintain comprehensive business records that continue to evolve alongside the UK business landscape.
How we verify every order
Before any data is supplied, every customer order is individually reviewed and validated.
Rather than simply exporting records from our database, we verify the selected businesses immediately before despatch to help ensure the information remains accurate, relevant and compliant for your campaign.
As part of this process, our team cross-checks records against trusted reference sources including:
Companies House
Royal Mail
BT
Membership organisations
Trade publications
In-house market research and validation
This final verification process helps ensure the data you receive has been specifically reviewed for your order and is as accurate and up to date as possible at the point of supply. Explore our B2B data and business databases.
