Companies House is Changing – Here’s What UK SMEs Need to Know
The government is rolling out major reforms to Companies House. These changes are designed to increase transparency and reduce economic crime, and they will affect every UK company, from startups to well-established SMEs.
If you run or manage a business, it’s important to understand what’s coming—and take action now to avoid last-minute stress later.
1. Directors Must Prove Who They Are
From autumn 2025, all company directors and people with significant control (PSCs) must verify their identity with Companies House.
- New directors will need to do this straight away when they’re appointed.
- Current directors will have 12 months to complete the process once it goes live.
Tip: It’s wise to act early and avoid delays when the deadline hits.
2. Filing Goes Fully Digital
Paper forms will soon be a thing of the past. Companies House is moving to a digital-only system, with all filings (including annual accounts) submitted via approved software.
- This change is expected within 2–3 years.
- If you’re still submitting paper accounts, now is the time to switch.
Tip: Digital filing is faster, cheaper, and more accurate—don’t wait to upgrade.
3. More Financial Information Will Be Required
The rules on financial reporting are tightening up:
- Small companies must file a profit and loss account and a directors’ report.
- Micro-entities must now file their profit and loss account too.
This makes credit checks easier—for you, your suppliers and your customers.
Tip: Start preparing now by checking your current reporting processes.
4. PO Boxes Are No Longer Allowed as Registered Offices
Every business must now have an “appropriate address” for its registered office.
This means:
- Someone at the address must receive documents.
- Deliveries must be able to be signed for.
Tip: Make sure your registered office is up to date and meets the new standards.
5. You Must Provide a Registered Email Address
Companies House now requires a registered email address for each company.
- This address will not be made public.
- It will be used for official notices and updates.
Tip: Make sure your email is monitored and up to date.
What Should SMEs Do Now?
To stay compliant and avoid disruption, SME owners and directors should start preparing now:
- Stay informed – Track the timeline for reforms and any new guidance.
- Review your processes – Check how you handle filings, office addresses and director records.
- Get digital – Switch to approved software for account filings.
- Start ID checks – Prepare directors and PSCs for the identity verification process.
- Talk to a professional – Don’t guess—get advice.
