UK Companies House Lead Generator - Enterprise API

The ONLY N8N workflow that handles 1,000+ companies without timing out

🚀 Why This Template Exists

Every other Companies House scraper fails at scale. They timeout. They crash. They lose data.

This workflow uses hybrid async processing - a technique usually found in £10,000+ enterprise systems.

You're not buying a template. You're buying production-grade infrastructure.
