One of the most significant changes for limited companies isn’t from HMRC — it’s from Companies House.
The reforms introduced under the Economic Crime and Corporate Transparency regime continue to roll out through 2025 and 2026.
Director identity verification becomes standard
All company directors and persons with significant control (PSCs) will be required to:
- Verify their identity
- Keep details accurate and up to date
- Resolve inconsistencies quickly
This reduces fraud but increases admin responsibility.
✅ What this means in practice:
Ignoring Companies House correspondence will now have consequences
Greater accuracy expectations on filings
Companies House is shifting from a passive register to an active regulator:
- Inaccurate filings can be queried
- Data can be rejected
- Penalties may follow persistent non‑compliance
Even small companies must ensure:
- Correct SIC codes
- Accurate director details
- Consistent figures with HMRC filings
Accountants and agents play a bigger role
Businesses using professional agents benefit from:
- Verified filing routes
- Reduced delays
- Faster correction handling
DIY filings are not banned — but they carry higher risk if errors arise.
✅ Key message:
Limited companies are expected to be better governed, not just registered.
