With the implementation of the Economic Crime and Corporate Transparency Act 2023, certain individuals connected to UK businesses are now legally obliged to verify their identity.
When the Companies House Identity Verification (IDV) regime came into force on 18 November 2025, it marked a fundamental shift in how directors, persons with significant control (PSCs), and their advisors interact with the UK’s corporate register. This reform, driven by the need for greater transparency and stronger defences against economic crime, continues to influence governance practices across sectors including manufacturing, professional services, healthcare, and construction.
At its heart, the regime obliges certain individuals connected to UK companies to prove they are who they say they are before they can hold key roles or submit important filings. Understanding what changed, why it matters, and how companies should respond is essential for leaders, especially in high-growth businesses.
What the IDV Regime Changed
The IDV regime introduced a new legal requirement: directors, PSCs and others in scope must verify their identity with Companies House and obtain a unique personal code. This was not a one-off deadline, but the start of a phased rollout aimed at embedding identity verification across Companies House. The requirement officially began on 18 November 2025 and has been supported by a 12-month transition period during which existing directors and PSCs are expected to complete verification prior to submitting their next confirmation statements.
Verification can be completed directly through the GOV.UK One Login Service or through an Authorised Corporate Service Provider (ACSP) such as an accountant or solicitor – also known as a Companies House authorised agent.
Once individuals have verified their identity, they will receive a personal Companies House code that must be provided when filling confirmation statements or assuming new roles. Failing to verify your identity can result in rejected filings, potential compliance penalties, or even criminal prosecution.

Why This Matters for Businesses
Identity verification is more than another compliance hurdle – it’s about trust and accountability. Historically, the UK’s corporate register faced criticism for incomplete, inaccurate, or fraudulent entries. By tying verified personal identities to company roles, the reforms help ensure that the people behind the companies are who they claim to be, strengthening data quality and deterring misuse of the register.
This matters particularly for high-growth businesses. Investors in manufacturing, professional services, healthcare, and construction businesses increasingly scrutinise governance, risk management, and transparency before committing capital or entering commercial relationships. A clean, well-maintained corporate record sends a powerful signal about a company’s maturity and readiness for growth or external investment.
For directors and leadership teams, identity verification reinforces personal responsibility for regulatory compliance. Getting ahead of requirements rather than responding late reduces the risk of administrative disruption and helps ensure filings can proceed smoothly.
Practical Lessons for Business Leaders
Although the initial phase of the identity verification is behind us, the underlying governance expectations remain vital. Directors and PSCs should:
- Keep verification codes up to date and linked properly to their roles well before filing deadlines
- Build identity verification into standard onboarding for new directors and company officers
- Educate finance, governance, and in-house compliance teams about where verification fits into wider corporate duty cycles – including annual confirmation statements
If your organisation uses an external agent for company filings, confirm whether they’re registered as an ACSP on the UK government’s list of providers. This ensures they can assist with identity verification legally and effectively.
Broad Impacts and the Future of UK Corporate Data
The IDV regime sits within a wider governmental effort to make the corporate environment more transparent and resilient against economic crime. Strong identity verification plays into the UK’s broader economic crime strategy and helps reassure investors and partners that the corporate data they rely on is reliable and trustworthy.
For businesses poised for growth, this focus on clarity and accountability creates opportunities. Companies that adopt rigorous compliance practices early (particularly around governance and public record accuracy) tend to attract better investor engagement and face fewer disruptions during transactional events like fundraising or M&A activity.
Turning Compliance into Business Advantage
Accurate and verified corporate records build investor confidence, smooth due diligence, and signal robust governance to partners and stakeholders. For high-growth businesses, this can make the difference between friction-filled transactions and seamless growth.
