Companies House Data

Companies House data gives you trusted UK company information, empowering your organisation to identify the right business, understand its status, and keep records accurate and up to date.

AFD integrates Companies House data into its Address Lookup and Data Cleansing solutions. During address search, the registered name, company number and status are shown helping users pick the right business. When an address is selected, our API returns the key Companies House fields to prefill your form or be stored within your CRM.

Please note: Companies House data is only available for electronically filed accounts, which currently represent around 60% of the 2.2 million accounts filed each year.

When business address databases are cleansed, the matching Companies House data that is relevant to you can be appended.

Key Uses

Capture clean, consistent company records as you go.
Auto-fill the registered name and company number, keep dates and formats consistent, and stop duplicates as records are created so your data stays clean.

Enhanced profiling of existing data.
Append Companies House data to your CRM to help segment by sector, size and status, then prioritise activity based on your ideal customer profile.

Confirm company details and status are accurate as you onboard.
Match the record to Companies House to check Active vs Dissolved, incorporation date and filing due dates, then flag any mismatch for review.

Use Cases

At point of address lookup

Get the right business first time. Many sites share a postcode. Show the registered name, number and status next to each address so users pick the legal entity, not just a building.

Prefill the company number and tick Active or Dissolved while you capture an address. Fewer mistakes and faster data entry.

Simple compliance. Incorporation date, filing due dates, SIC, and company status all help simplify compliance and speed up KYC checks during onboarding.

Stop duplicates by using the company number as a unique key with the accurate address so the same business is not added twice under slightly different names.

When appending address data during cleansing

Clean and enrich your CRM. Match each address to a company number, then append status, SIC and filing dates for reporting and segmentation.

Reduce risk. Flag dissolved firms or overdue filers and remove them from mailings or tighten credit terms.

Target better. Use SIC and attributes to build sector lists and size a market by region.

Single customer view. Link trading locations back to the legal entity to dedupe accounts and roll up spend.
