Companies House matching

Thawly is UK-first, and Companies House is the spine of how we monitor your accounts. Every company you add gets looked up against the official register so we can track filings, officer changes, and other UK-specific signals you can't get from a generic enrichment tool.

Auto vs manual#

When you upload a CSV or add a company by hand, Thawly searches Companies House by name and picks the strongest match. If there's a confident hit, the match is set to auto and we email you a one-click confirmation link. Click "yes" and the match becomes confirmed. Click "no" and it's reset, ready for you to search manually.

The confidence dot#

Next to every company in the Upload list you'll see a coloured dot:

• Green (confirmed) — you (or someone on your team) explicitly confirmed this match.
• Amber (auto) — Thawly's best guess; not yet confirmed.
• Grey (none) — no match attempted, or rejected. The company is still monitored for non-CH signals.

Fixing weak matches#

Open Upload and use the search button on any company to look it up against Companies House by hand. Pick the right registration and the match is locked in as confirmed. Companies with confirmed matches contribute the strongest signals — fuzzy and unmatched companies are downweighted at digest time, so this is the highest-leverage tidy-up you can do.
