B2B Lead Generation in the UK: Channels, Data and PECR Rules

The UK has a mature B2B market with excellent public company data and clear (if nuanced) rules on B2B marketing. Here's how to generate leads there.

UK data sources

• Companies House for registered companies, directors and SIC codes
• Google Maps for local SMBs
• LinkedIn for decision makers
• Industry bodies and trade associations
• Local chambers of commerce

Rules for B2B email and calls

• Under PECR, emailing corporate subscribers (limited companies, LLPs, government bodies) for B2B marketing generally doesn't require prior consent, but you must identify yourself and offer an opt-out.
• Sole traders and some partnerships are treated like individuals: you need consent or a soft opt-in.
• UK GDPR still applies to personal data such as named business emails: you need a lawful basis (often legitimate interests) and transparency.
• For calls, screen against TPS and CTPS before calling.

This isn't legal advice; check the ICO's guidance for your situation. See GDPR legitimate interest vs consent.
