Companies House


Find basic information about organisations on the public register.


The Companies House dataset is supplied by the Government and includes such information as registered address, company type, company status, and previous names.

Available online, integrated, standalone software or via a bureau service. We can also provide bespoke systems tailored to your specific requirements and CRM integrations.

By using Hopewiser’s address validation with Companies House data, you will be able to:

  • Verify a company’s address and other details.
  • Obtain previous information.
  • Target companies within a specific area.
  • Understand their market share.
  • Plan marketing strategies.
  • Understand where your business customers are.



Hopewiser provides two alternate datasets derived from the Companies House data. The first is a Master Address File (MAF) with extra data, where the address information is sourced from Companies House.

The second can be used alongside Hopewiser’s products, and address information is validated against the Royal Mail Postcode Address File (PAF). Both datasets undergo a bespoke enhancement process to ensure the highest level of quality control.

Both offerings include access to the same non-address data items, including:

  • Company name
  • Company number
  • Company status
  • Incorporation date
  • Dissolution date
  • SIC codes
  • Previous company names

With Hopewiser’s solution you’ll also receive:

  • Monthly updates of the latest Companies House data.
  • Updated information for existing companies whereby their details have changed.
  • Inclusion of new companies registered during the previous month.
