For UK private equity firms planning bolt-on acquisitions, this continuity reduces operational risk immediately after completion.

Free Public Access

  Unlike most due diligence software, Companies House is free to access. For angel investors in the UK, this makes it an essential starting layer before purchasing premium data subscriptions.

  • Review confirmation statements for share changes
  • Check director appointment timelines
  • Review registered charges
  • Verify registered office history
