Companies House WebFiling Explained: The 2026 Rule Changes
Companies House WebFiling is the official online portal for submitting company documents like annual accounts and CS01 confirmation statements. In February 2026, significant reforms under the ECCTA come into effect, completely updating how businesses interact with Companies House.
Key Changes from February 2026
- Mandatory ID Checks: Every director and PSC must complete Companies House ID verification before any filing is accepted. No exceptions.
- GOV.UK One Login Replaces Old Logins: Each individual—no more shared or company-wide accounts—will have a personal login tied to their ID.
- Higher Filing Fees: The cost for core filings increases substantially (e.g., digital CS01 rises from £13 to £50).
- Enhanced Data Requirements: Filings must include current, verified officer and PSC information. Submissions with outdated details will be blocked.
- Zero Tolerance Compliance: Any filings lacking full ID verification or up-to-date PSC details are rejected immediately. The penalty regime is much stricter.
In 2026, a design consultancy, BrightStart Solutions Ltd, attempted to file annual accounts using their director’s old WebFiling password. Without the updated ID check, the system blocked their submission, resulting in a late penalty of £150 and significant stress. Avoid this by preparing early and ensuring new logins and ID verification are complete.
Actions You Must Take by February 2026
- Register every filer (directors, PSCs, agents) for their own verified GOV.UK One Login.
- Complete Companies House ID verification for all directors and PSCs.
- Update and verify all personal and company information before every filing.
- Use ECCTA-compliant templates for new legal standards.
- If you use an accountant or agent, ensure their ACSP (Authorised Corporate Service Provider) details are up-to-date and linked.
Why Is Companies House ID Verification Crucial for Directors and PSCs?
From February 2026, it becomes a legal requirement that every director and PSC completes Companies House’s official ID check. This process is central to the ECCTA’s objectives of reducing company fraud and increasing transparency.
What This Means in Practice
- Every director and PSC must complete a photo ID and address check through GOV.UK One Login before any company document is filed or approved.
- Relying on only an accountant or company secretary is insufficient; the legal responsibility sits directly with directors and PSCs.
- Failure to verify on time will lead to an automatic rejection of all filings, costly late fees, and potential strike-off of the company from the register.
How to Complete Companies House ID Verification for WebFiling: Step-by-Step
Completing the ID check is now the gateway for every company action. Follow these steps to pass first time:
- Gather Documents:
You will need a valid passport or UK driving licence, and proof of your UK address (e.g. a recent utility bill or bank statement, dated within three months). - Set Up Your GOV.UK One Login:
Go to the Companies House WebFiling portal. Follow prompts to register or link your email, using your legal name. - Enter Your Details:
Ensure your name, address, and date of birth identically match your ID documents. Any errors will slow or block the process. - Upload Your Photo ID:
Scan and upload high-quality images (PDF or JPEG) of your passport or driving licence. - Submit Proof of Address:
Upload a recent document showing your name and the address you will register with Companies House. - Facial Recognition:
Complete the selfie or live video check, as prompted. - Confirm Contact Info:
Enter email and phone numbers. Verification codes are sent to both; respond quickly to complete the process. - Finalise and Wait:
After submission, Companies House will confirm when your ID is verified (typically within a day, but allow extra time for queries).
Delta Marketing Ltd’s director uploaded an expired passport and received an immediate rejection, leading to panic as the filing deadline approached. Always check expiry dates.
If you’re unsure about any detail, run through our pre-submission checklist to reduce the risk of failed verifications.
What Documents Are Accepted for Companies House ID Checks?
To pass ID verification you must provide:
- Current Photo ID: UK (or, if applicable, international) passport, or UK photocard driving licence.
- Proof of Address: A recent utility bill, bank or building society statement, council tax bill, or UK government letter—dated within the last three months.
- Digital Format Required: Colour scans or digital photos (JPEG/PDF) must be clear and readable.
- Data Must Match: Your name, address, and date of birth must align with those already held on record by Companies House.
If your address on your passport is outdated, use a recent utility bill to confirm your current residence—otherwise, your ID check may fail.
Review all details and resolve any inconsistencies before starting the verification to avoid unnecessary delays.
GOV.UK One Login: How Does it Work for WebFiling?
GOV.UK One Login is the new universal way to access all Companies House filings from 2026 onwards. Its purpose is to tighten security and ensure every submission is traceable to a specific, verified individual.
What You Need to Know:
- Unique Login for Each User: Every director, PSC, company secretary, or agent must have their own GOV.UK One Login.
- No More Shared Logins: Legacy company or agent logins will be permanently disabled.
- Individual Verification Required: Each login is tied to a real person who must complete ID verification.
- Live Submission Tracing: The identity of every filer is now logged, increasing accountability and compliance.
Metro Tech Ltd tried to add a new director, but their submission was blocked because the director had not set up a GOV.UK One Login. Early preparation avoids these last-minute problems.

Key ECCTA 2026 Compliance Rules for Companies House WebFiling
The Economic Crime and Corporate Transparency Act 2026 introduces sweeping new duties for UK companies, raising the bar for transparency and real-time accuracy.
Core ECCTA Requirements
- Director and PSC Verification: Every director and PSC must complete full ID checks through Companies House before any documents are accepted.
- Enhanced PSC Transparency: PSCs now face an ongoing duty to keep information current, not just at annual events.
- Accurate and Continual Filings: All filings must be up-to-date, with details kept accurate throughout the year, not just at annual events.
- Named Filer Traceability: Every filing is now clearly linked to a named, ID-verified individual.
- Powerful Enforcement Tools: Companies House can now instantly reject non-compliant filings, enforce accelerated fines, and start swift strike-off for non-compliance.
| Compliance Area | Before ECCTA 2026 | After ECCTA 2026 |
|---|---|---|
| Director Verification | Only for some filings | Mandatory for all filings |
| PSC Registration | Annual update, basic checks | Continuous accuracy and ID checks required |
| Filing Method | Shared accounts allowed | Only individual, verified logins permitted |
| Fees | Lower (e.g. CS01 £13) | Higher (e.g. CS01 £50, others up too) |
| Penalties | Standard, with grace period | Faster and stricter, including instant rejection |
QuickShop UK Ltd, a retail startup, skipped PSC updates. When trying to submit annual accounts, their filings were blocked, causing fines and damaging their reputation.
Set regular quarterly reminders to check the accuracy of all director and PSC information, not just before annual filings.
ECCTA: Responsibilities for Directors and PSCs
- Directors must personally verify their identity and keep information actively updated.
- PSCs now face enhanced ID and accuracy requirements, with filings rejected if out of date.
- Failure to use accurate, up-to-date contact and address information risks blocked submissions and swift penalties.
- If using any third-party agent (e.g. an accountant), confirm their ACSP registration is current—otherwise, their filings will not be accepted.
Pathway Consulting Ltd relied on a non-registered agent. Their confirmation statement was blocked, incurring late fees and a compliance headache.
Regularly audit your agent or service provider’s Companies House registration status before permitting them to act.
New Deadlines and Fees for Companies House: What Changes from February 2026?
The fee structure and filing deadlines are majorly revised under ECCTA, with higher costs and more severe late penalties.
| Event or Filing | Previous Fee | Fee from Feb 2026 | Deadline / Requirement |
|---|---|---|---|
| CS01 Confirmation Statement | £13 (digital) | £50 (digital) | Annually, after ID check completion |
| Company Incorporation | £12 (digital) | £100 (digital) | On incorporation, after all officers verified |
| Voluntary Strike-Off | £8 | £13 | Upon application |
| Annual Accounts | £0 | £0 | 9 months post year-end (only after ID checks) |
- Deadlines Remain Tighter: Accounts must be filed within 9 months after year-end, but now only if all filers’ ID checks are approved.
- Late Penalties Escalate Quickly: Filing just one day late incurs a penalty; further delay makes the fines rise steeply.
- Action Required: Start ID verification well before your filing deadline. Initial checks may take extra days, especially for first-time users.
Download our compliance calendar to add automatic reminders for both deadlines and required ID updates for your directors and PSCs.
WebFiling Submission Checklist for 2026: What Details Must Be Included?
Before submitting any Companies House filing after February 2026, you must check the following:
| Required Item | Description | Why It Matters |
|---|---|---|
| Verified Director ID | Up-to-date passport or driving licence & proof of address | Your filing will be refused otherwise |
| Updated PSC Details | PSC information that matches current records | Essential for legal compliance |
| Confirmation Statement (CS01) | Accurate, full ownership and company details | Legal requirement—must be correct |
| Annual Accounts | Financial year summary, meeting new standards | Non-compliance triggers penalties |
| Accurate, Live Contact Details | Valid email and telephone number | Companies House will not chase errors |
| ACSP Registration (if using an agent) | Agent listed on official register | Unregistered agents’ filings are blocked |
Nova Digital Ltd failed to submit up-to-date PSC info alongside director ID and saw their submission rejected. Keeping every detail current is now non-negotiable.
Our free checklist tool ensures you don’t miss any required detail—essential for directors managing multiple roles or companies.
The Most Common WebFiling Mistakes to Avoid in 2026
Filing mistakes are now costlier and more likely to result in rejections or fines under the ECCTA regime.
- Using Old Logins: Shared or legacy company logins result in instant filing rejection—move to individual GOV.UK One Login.
- ID Mismatches: Mistyped names, expired IDs, or mismatching addresses stop verification in its tracks.
- Missing or Outdated PSC Details: Such omissions will block a submission and can trigger penalties.
- Late Filings: ECCTA rules mean penalties and strike-off for late filings are harsher and enforced more quickly.
- Unregistered Agents: Accountants or lawyers not registered as ACSPs will see their clients’ filings automatically rejected.
BuildBright Ltd overlooked the PSC’s ID verification. Their CS01 submission bounced, and a £150 fine followed—avoidable with a checklist or digital tool.
Before each submission, pause and conduct a “double-check” using an automated or AI-driven review tool to minimise human error.
Can You Still Use Accountants or Lawyers for Companies House Filings After 2026?
Yes, but only if they are properly registered as Authorised Corporate Service Providers (ACSPs) and linked to your company.
- Agent Registration Is Mandatory: Accountants, lawyers, or secretaries must obtain ACSP status and undergo their own ID and company checks.
- Authorisation Must Be Checked: Always verify any agent’s ACSP status with Companies House before permitting them to handle filings.
- Unregistered Filings Will Be Blocked: Any filing made by an unregistered or unlinked agent will not even reach Companies House for review.
Pixel Logic Ltd instructed an agent without checking ACSP status. The agent’s filings were blocked, causing delay and risking late penalties.
Ask your agent for proof of ACSP registration every year—making verification part of your company’s annual compliance process.
