Introduction
UK Companies House reforms introduce stricter identity checks, filing controls, and transparency requirements. These changes affect how companies submit information and how inaccuracies are challenged. We outline what UK businesses need to understand, what will change in practice, and how to prepare before enforcement tightens.
What changes to identity verification, filing rules and transparency requirements matter most for SMEs?
The reforms mark a shift in how Companies House operates. It is no longer a passive recipient of information, but an active gatekeeper with powers to verify identities, question filings, and improve the reliability of the register. For SMEs, this means greater accountability and less margin for error.
Why is identity verification being introduced for directors and PSCs?
Identity verification is being introduced to reduce fraud and misuse of UK companies. From 18 November 2025, all new directors and people with significant control (PSCs) must verify their identity before appointment, with existing directors and PSCs required to verify during a 12-month transition period. Verification can be completed directly or via an authorised intermediary. The official requirements and timelines are set out in government guidance on identity verification for Companies House.
Who will be allowed to file information with Companies House going forward?
Filing controls are tightening alongside identity verification. While directors and PSCs are the first groups affected, Companies House is introducing an Authorised Corporate Service Provider (ACSP) regime so that agents filing on behalf of companies are properly registered and supervised. For businesses, this means:
- Clear authorisation of who can submit filings
- Greater reliance on verified identities
- Reduced tolerance for informal or shared access
Some filer-related requirements are being phased in after director and PSC verification, but the direction of travel is clear.
What new powers will Companies House have to question or reject filings?
Companies House now has expanded powers to query, reject, annotate, or remove information that appears inaccurate or inconsistent. It can also share concerns with law enforcement and other regulators.
For SMEs, this means filings are more likely to be delayed or challenged if information does not align with existing records or appears implausible.
How will transparency rules affect company ownership and control disclosures?
Transparency around ownership and control remains central. PSC information must be accurate and kept up to date based on statutory tests, such as share ownership, voting rights, or significant influence. Errors that may previously have gone unnoticed are now more likely to be identified as data checking becomes more robust.
How can businesses adjust internal processes to stay compliant as rules tighten?
Awareness alone is not enough. Businesses need to adapt internal processes so that compliance is deliberate, controlled, and reviewable.
Who should take responsibility for Companies House compliance internally?
Directors remain legally responsible for filings, even where tasks are delegated. We recommend assigning clear internal ownership of Companies House compliance, with:
- A named director responsible for oversight
- Documented approval before submissions
- Clear escalation where information changes
This mirrors how most businesses already approach tax compliance and reduces risk.
How should companies manage authorisation for accountants and agents?
Where accountants or agents file on a company’s behalf, authorisation should be explicit and regularly reviewed. This includes confirming who is authorised, what filings they handle, and how verification requirements are met.
Our Companies House support services help businesses formalise these arrangements and reduce compliance risk.
What filing deadlines and confirmation processes need closer control?
With increased scrutiny, late or inaccurate filings are more likely to attract attention.
Businesses should strengthen controls around:
- Confirmation statements
- Director or PSC changes
- Registered office and contact details
Simple pre-filing checks can prevent avoidable errors.
What records and governance practices should companies strengthen before reforms take effect?
As data is cross-checked more actively, the accuracy of underlying records becomes critical.
Which records should be reviewed and updated first?
From November 2025, companies are no longer required to maintain certain internal statutory registers, such as registers of directors or PSCs. However, companies must still ensure that all required information held at Companies House is accurate and current. The register of members (shareholders) remains a core internal legal record and should be kept up to date alongside share documentation.
How important is consistency between Companies House and HMRC records?
Consistency is increasingly important as data sharing improves. Differences between Companies House filings and HMRC records, such as accounting periods or director details, can trigger queries. Guidance on company and accounting records for limited companies is set out by government here.
What governance habits help reduce compliance risk long term?
Strong governance does not need to be complex. Practical habits include:
- Annual reviews of Companies House information
- Prompt updates following changes
- Clear documentation of key decisions
For growing businesses, this supports better strategic decision-making as well as compliance. Our virtual finance director support helps businesses align governance with long-term planning.
Practical preparation checklist
| Requirement | Who is responsible | What to do before enforcement tightens |
| Identity verification | Directors and PSCs | Confirm who must verify and complete checks |

Conclusion
The new Companies House reporting standards represent a fundamental change in how company information is verified and enforced. Preparation now is about clarity, accuracy, and accountability rather than reacting to queries later. We encourage UK companies to review their current position, identify gaps early, and put stronger processes in place. If you would like to discuss how these changes affect your business and what practical steps to take next, we’re happy to help you review your position and plan ahead with confidence.

Yes. The reforms apply to all UK companies, regardless of size, although the impact may feel greater for SMEs with informal processes.
Will Companies House still accept paper or late filings?
Digital filing remains standard, but late or inaccurate submissions are more likely to be challenged under the new powers.
Do we still need to keep statutory registers internally?
Most internal registers are no longer required after November 2025, but companies must still ensure Companies House information is correct and keep a register of members.
What happens if Companies House queries our information?
Filings may be delayed, rejected, or referred for further review, which is why preparation and accuracy are increasingly important.
