Companies House Identity Verification
PowerStone Accountants is an Authorised Corporate Service Provider (ACSP), meaning we can verify an individual’s identity for the purpose of getting them verified at Companies House.
Why it matters
Identity verification is a statutory requirement under Companies House rules.
It is designed to reduce fraud, increase transparency, and ensure that individuals listed on the UK companies register are real and accountable.
Who we verify
Who this service is for
Persons with Significant Control (PSCs)
Individuals making new appointments or updating existing Companies House records
Our role
What we do
As an ACSP, we complete identity verification in line with Companies House requirements. This includes:
- Reviewing approved photo identity documents
- Confirming identity through an in-person or live video check
- Carrying out electronic identity verification where appropriate
- Retaining verification records securely as required by law
Once verification is completed, Companies House issues the individual’s Unique Identifier (UID) when the relevant filing is submitted or updated. PowerStone Accountants does not issue or allocate UID numbers.

What you’ll need
- A valid passport, UK photocard driving licence or a Citizen’s Card
- An acceptable proof of address e.g. Bank Statement, Utility Bill
- Availability for a short live verification (in person or video)
Verification cannot be completed without compliant photo identification.
What we cannot do
- Verify identity without acceptable photo ID
- Verify individuals who cannot directly participate in the verification process
- Complete verification on an informal or undocumented basis
- Issue Companies House Unique Identifiers

FAQs
Frequently asked questions
I’ve lost my passport or driving licence – can you still verify me?
No. Companies House requires valid photo identification. You will need to obtain replacement documents or use Companies House’s own verification route.
The individual has severe illness – can a family member confirm identity?
No. Verification requires the individual’s direct participation and capacity. In these circumstances, Companies House’s own process or alternative legal arrangements must be used.
Do you verify overseas directors?
Yes, provided acceptable photo ID is available and a live video verification can be completed.
Can this be done urgently?
Yes. Same-day verification may be available subject to availability and an additional fee.
