About the data

What's in a record — and what never can be.

Everything comes from a company's entry on the Companies House register: its name, its number, the registered office and postcode, the SIC sectors it chose, and an optional named director. Nothing that would put GDPR at risk.

✓ In every record

  • Company name
  • Company registration number
  • Registered office address & postcode
  • SIC (sector) codes
  • Date of incorporation
  • Named director (optional, where filed)

✗ Not available — here's why

  • Telephone numbers
  • Email addresses

These are never captured at registration, so no provider can supply them for a brand-new company — they don't exist yet. By the time they appear on marketing systems a year or more later, the firm has usually already bought what you wanted to sell.

Why post, and why it's GDPR-friendly

A company must legally receive post at its registered office, so business mail is expected there. We share that public address — never a director's home — which keeps you on firm ground under legitimate interest.

It's the public registered office

The address is on public record at Companies House, and company post must legally be received there.

Legitimate interest, not consent

You select firms by sector and geography because they have a genuine interest in your service — a recognised basis for B2B post.

No spam filter to beat

Royal Mail never scans your letter to see whether it went to thousands of others, the way email systems do.

Forwarding addresses removed

Worried it's an accountant or virtual office? We strip out most mail-forwarding addresses for you.
