How to File a Confirmation Statement Online Without Errors in 2026

You can file a Confirmation Statement online without mistakes by preparing accurate company details, verifying director and PSC data, and using Companies House WebFiling or an accredited third‑party filing service to validate entries before submission. 

How do I prepare to file a Confirmation Statement online without mistakes?

Prepare accurate company details, confirm officers and PSCs, and gather supporting ID and address proof before you start the online form.
Gather the company number, registered office address, full names and service addresses of all directors, and PSC data. Check the company’s SIC codes and share capital schedule. Reconcile this information with your last Confirmation Statement and the Companies House register. Use a spreadsheet to compare fields and highlight differences.

What online methods can I use to file a Confirmation Statement?

Use Companies House WebFiling or an accredited third‑party agent to submit the Confirmation Statement electronically.
Companies House WebFiling accepts direct submissions from registered accounts. Third‑party commercial filing platforms provide guided forms and automated validations. Choose a method that validates email formats, address fields, and share capital totals. For businesses using software, ensure it supports Companies House XML upload and follows the Companies House filing schema.

How do I verify director and PSC information to avoid errors?

Verify director and PSC names, dates of birth (month/year only for PSCs), service addresses, and nature of control against original onboarding documents.
Check passports or driving licences, proof of service addresses, and PSC declaration documents. Confirm whether PSCs are individuals or entities; record the correct legal form (e.g., UK-registered company, trust). For PSCs that are individuals, record the nature of control using standard terms: “holds 25% or more shares”, “right to appoint/remove directors”, or combined control. Update entries if any resignations or appointments occurred since the last filing.

What common data-entry mistakes cause rejections or corrections?

Typographical errors in the company number, incorrect SIC code, wrong share capital totals, and mismatched PSC details cause most rejections.
Entering the wrong company number prevents the form from linking to the right record. Using an outdated SIC code misclassifies the business activity. Reporting share capital with arithmetic errors or listing share classes incorrectly leads to discrepancies. PSCs recorded with full dates of birth instead of month and year trigger validation flags. Service addresses that use PO boxes instead of physical service addresses often require correction.

How do I confirm share capital and shareholder details precisely?

Reconcile share registers, count issued shares by class, and report nominal value and total aggregate properly on the form.
Open the statutory share register and tally each class: number issued, nominal value per share, and total nominal value. Calculate the aggregate share capital as the sum of (number issued × nominal value) across classes. Record any allotments, transfers, or buybacks made since the last statement. If there are fully paid and partly paid shares, state the payment status clearly. Keep working papers that show your calculations.

When should I update the SIC code and company details?

Update the SIC code only when the principal business activity has materially changed since the last filing.
Check the current SIC against your trading activities. Use the official SIC list from Companies House and choose the single most relevant code, or add secondary codes if necessary. Update the registered office address immediately if it has changed. Record officer appointments or resignations occurring on or before the Confirmation Statement date of submission.

How can I avoid technical errors when using WebFiling or third‑party platforms?

Validate each field, use browser compatibility best practices, and save drafts before final submission to prevent technical errors.
Use an up‑to‑date browser and allow pop‑ups for the filing site. Save or export drafts as PDFs or XML, where the platform allows. Validate email addresses and international character sets. Double‑check numeric fields to avoid comma misplacement. If using third‑party software, ensure it’s accredited for Companies House filing and that it produces the correct submission format.

How long does the online filing take, and what deadlines matter?

Filing typically takes 10–60 minutes, depending on preparation; the Confirmation Statement must be filed within 14 days of the review date.
Prepare all materials beforehand to keep the form completion time under one hour. The statutory deadline is 14 days from the review date (confirmation date). If you file late, Companies House records the missed deadline and penalties for late Confirmation Statements are handled under company law and creditor/risk considerations. Track upcoming deadlines using calendar reminders tied to the company’s review date.

What validation checks should I run before clicking submit?

Run four checks: company number match, officer and PSC reconciliation, share capital arithmetic, and address formatting compliance.
Confirm the company number on every page. Reconcile officer names and service addresses to your statutory registers. Verify share class totals and nominal values with your share ledger. Ensure registered office and service addresses meet Companies House formatting rules (no PO boxes for service addresses). Export a preview or PDF and review on-screen.

What evidence should I keep after filing to support the online Confirmation Statement?

Retain the submitted PDF/XML, a copy of the statutory registers used, and a timestamped confirmation email or receipt from Companies House or the filing agent.
Store the saved submission file in your company records for at least five years. Keep PDFs of the share register, director and PSC registers, and supporting ID used for verification. Save the Companies House acknowledgement email and any transaction reference numbers produced by the filing system.
