Leadistry is a UK-only B2B database. Here’s exactly how every record is built, our legal basis, and how long we keep data.
The official register, via the public API and bulk data files: name, address, SIC codes, incorporation date, status, charges and directors.
We visit each company's own site where discoverable, and use public search engines and professional profiles to find the site and the correct named contact, extracting only what is already published.
Records are cached, re-verified from source each month, and suppression requests are honoured permanently.
Every record is built from public sources:
The UK government’s official register of limited companies. We use the public Companies House API and bulk data files. This is the source for company name, registered address, SIC codes, incorporation date, status, charges, filing deadlines, and director information including nationality and stated occupation.
We visit the website of each company (where one is discoverable) and extract the contact details the company itself has chosen to publish, such as business email addresses, phone numbers, and named contacts on team or contact pages.
We use public search engines and public professional profiles (for example LinkedIn) to locate a company’s website, identify the correct named business contact, and record a director’s public LinkedIn profile where one is publicly available. We do not log in to those platforms or collect anything a person has not made public.
Every record starts with Companies House and the contact details a company publishes on its own website, confirmed against public professional profiles. Company data you can trace to a filing.
We process this data under UK GDPR Article 6(1)(f), legitimate interests. Direct marketing to corporate subscribers (i.e. limited companies) is permitted under the Privacy and Electronic Communications Regulations (PECR) without prior consent, provided opt-out is honoured.
We do not process special category data. We do not market to consumers. We do not sell personal data to advertising networks.
We retain company and business-contact records for as long as the company remains active on the public Companies House register, and re-verify them from source periodically (a monthly re-verification). We remove a company on a valid suppression request, and suppression is then honoured permanently.
To remove a company, use the public removal form, no account required.
