Custom engineered Data & Analytics integration

Companies House & HubSpot integration

Custom engineered for your business by SpotDev's accredited developers

Connect HubSpot to the Companies House API so company records are looked up and enriched with the registered name, number, address, incorporation date and status from the public register, checked automatically rather than typed in by hand.

  • 1–2 weeks typical turnaround
  • £3k typical investment
  • API key

Why connect Companies House to HubSpot

Sales and operations teams copy company numbers, registered addresses and trading status from the Companies House website into HubSpot by hand, and nothing tells them when a company they sold to last year has since been dissolved.

  • The Companies House Public Data API returns company profiles, registered office addresses, officers, persons with significant control, filing history, charges and insolvency data over REST
  • Authentication is an API key sent as the username in HTTP Basic authentication, and the service allows up to 600 requests in a five-minute window, which is ample for lookups triggered from HubSpot workflows
  • Company search endpoints let the integration find the right entity from a trading name before writing the company number back to HubSpot
  • The Companies House Streaming API pushes changes as they happen, so status changes can be caught without polling if you need continuous monitoring

What you can do with Companies House and HubSpot

Typical flows between Companies House and HubSpot.

  • A new HubSpot company triggers a lookup by name or company number and the verified profile is written to HubSpot company properties
  • Registered office address, incorporation date and company status are mapped to dedicated properties so they are not confused with trading details entered by sales
  • A scheduled or on-demand re-check before a deal is marked won flags companies whose status has changed since the record was created
  • Officer and persons-with-significant-control data can be pulled for compliance or credit checks where your process needs it

Companies House & HubSpot integration: FAQs

Does Companies House have an API that HubSpot can use?
Yes. Companies House runs a developer hub at developer.company-information.service.gov.uk with a Public Data REST API and a Streaming API. You register an application to receive an API key, and requests use HTTP Basic authentication with the key as the username.
What data can sync between Companies House and HubSpot?
Company profile, registered office address, status, officers, persons with significant control, filing history, charges and insolvency information, one-way from Companies House into HubSpot. Nothing is written to the public register.
How long does a Companies House HubSpot integration take?
1 to 2 weeks. The API is well documented and the integration is a lookup and write-back, so the main decisions are which fields to store and when the lookup runs.
How much does a Companies House HubSpot integration cost?
From £3k for the lookup and enrichment described here. Adding officer or PSC data, or continuous monitoring through the Streaming API, is quoted on top after scoping.
