Many founders are caught off guard when their UK company application is rejected, often for small mistakes that could have been fixed in minutes. Companies House makes it clear that applications are refused when the submission contains incomplete details, incorrect personal information or a non-compliant company name, as outlined in its official guidance.
With Companies House handling more than 800,000 incorporations a year, even routine errors add up to a significant number of rejected filings. Most issues stem from inaccurate director information, the wrong SIC code or using an address that doesn’t meet statutory requirements.
This guide highlights the specific reasons UK company application gets rejected, helping you avoid the common pitfalls that slow down the incorporation process.
Common Reasons UK Company Application Gets Rejected
1. Incorrect or Incomplete Company Name
Company names are one of the most frequent reasons for rejection. Applications fail when the proposed name is identical or too similar to an existing company, which often happens when applicants skip the official availability check.
Names that contain sensitive terms such as “Group”, “International” or “Authority” also require permission, and Companies House will refuse the application if this evidence isn’t included.
Rejections also occur when the name uses disallowed characters, contains offensive wording or implies an activity the company isn’t authorised to carry out. Reviewing the naming rules and checking the register beforehand prevents most of these issues.
2. Errors in Director or Shareholder Details
Many applications are rejected because the personal details of directors or shareholders don’t meet Companies House requirements. Even small discrepancies can trigger a refusal. Common issues include incorrect dates of birth, mismatched addresses, spelling errors in names or missing nationality information.
Applications also fail when the service address and residential address are confused or when details don’t match identity verification records. If a director’s information appears inconsistent with past filings, Companies House may return the application for clarification. Reviewing each entry carefully and ensuring all information matches official documents helps avoid delays.
3. Invalid Registered Office Address
Companies House rejects applications if the registered office address doesn’t meet statutory requirements. The address must be a real, physical location in the UK where official notices can be delivered.
Many applications fail because the address is outside the UK, incomplete or uses a PO box without the full, deliverable address. Rejections also occur when the listed address doesn’t actually belong to the applicant or when the formation agent’s address is used incorrectly.
Companies House may also return the application if mail sent to the address is repeatedly undeliverable. Verifying that the address is valid, accessible and located in the correct jurisdiction prevents most issues.
4. Incorrect SIC Code Selection
Applications are often rejected when the chosen SIC code doesn’t match the company’s actual business activity. Many applicants select a code that is too broad, outdated or unrelated to what the company intends to do. Companies House may return the application if the activity is unclear or if the SIC code contradicts other information in the filing.
Leaving the SIC section blank is another cause of refusal. Reviewing the official SIC list and choosing the most accurate code helps avoid delays and ensures the company is classified correctly from the start.
5. Problems with the Memorandum and Articles of Association
Rejections occur when applicants submit Memorandum or Articles of Association that don’t meet legal requirements. Issues include using an unsupported template, altering clauses incorrectly or creating share structures that conflict with the documents.
Companies House may also reject the application if signatures are missing or the documents contain formatting errors that make them invalid.
Most first-time founders avoid these problems by using the model articles, but customised articles must be drafted carefully to remain compliant. Ensuring the documents align with the share structure and company type prevents unnecessary setbacks.
6. Issues with Share Structure or Statement of Capital
Applications frequently fail because the statement of capital doesn’t match the share allocation or because the information is incomplete. Common mistakes include inconsistent share values, unclear ownership percentages, missing shareholder details or issuing shares that don’t align with the Articles.
Companies House also rejects filings when applicants misunderstand how to record multiple classes of shares or leave the rights attached to each class undefined. Checking that the share structure is accurate, consistent and clearly described significantly reduces the risk of rejection.
7. Payment Problems During Submission
Some applications are rejected simply because the payment doesn’t go through. Failed card payments, expired cards or blocked transactions stop the submission from being processed. Duplicate payment attempts can also freeze the application while the system reviews the transaction.
When payment fails, Companies House doesn’t receive the application, even if all the details were correct. Verifying payment details and ensuring the transaction completes successfully is an easy way to avoid this issue.
8. Duplicate or Multiple Applications
Companies House may reject an application if it appears to be a duplicate of one already submitted. This often happens when applicants think the first attempt didn’t go through and submit again, or when multiple agents unknowingly file the same company name on behalf of the same client. Duplicate filings also raise compliance concerns, prompting Companies House to stop the process until the matter is clarified. Submitting only once and waiting for confirmation prevents unnecessary complications.
9. Identity Verification Failures
For online incorporations, identity verification is mandatory. Applications are rejected when a director or shareholder fails the ID check because their details don’t match official records or the uploaded documents are unclear.
Unsupported ID types, expired passports or inconsistencies between the application and verification data are also common causes. Using someone else’s information or attempting to bypass verification leads to automatic refusal.
Completing the ID check carefully and ensuring all details align with the application avoids delays.

10. Suspicion of Fraud or Non-Compliance
Companies House may reject an application if the information provided raises concerns about potential fraud or non-compliance. This includes inconsistent personal details, high-risk addresses, unclear business activities or filings that resemble known fraudulent patterns.
Applications may also be returned if the company appears to be set up for an unlawful purpose or if the information is incomplete in a way that prevents proper checks. Providing accurate, transparent details and ensuring the company’s purpose is legitimate helps avoid additional scrutiny.
Conclusion
Most UK company application rejections come down to simple oversights: a name that doesn’t meet the rules, inconsistent personal details, the wrong SIC code or documents that don’t align with the company structure.
These issues are easy to avoid with a careful review before submitting the form. Companies House is strict about accuracy because the information becomes part of the public record, so even small discrepancies can cause delays.
By understanding the most common reasons applications are refused, you can file with confidence and ensure your company is incorporated without unnecessary setbacks.
FAQs
1. What is the most common reason Companies House rejects applications?
The most frequent issue is a company name that doesn’t meet the legal rules. This includes names that are too similar to existing companies, contain restricted words or use characters Companies House doesn’t allow.
2. Can a UK company application be rejected if I choose the wrong SIC code?
Yes. An inaccurate or irrelevant SIC code can lead to rejection, especially if it contradicts the business activity described elsewhere in the application.
3. Does Companies House verify director identities before approval?
For online applications, identity verification is mandatory. If a director or shareholder fails the ID check or their details don’t match official records, the application will be refused.
4. Can I use my home address as the registered office?
Yes, as long as it’s a valid UK address where official mail can be delivered. However, the address will appear on the public register, so some applicants prefer using a service address or registered office provider.
5. What should I do if my company application is rejected?
Companies House will state the reason in the rejection notice. Correct the issue, update the information and resubmit. Most mistakes can be fixed quickly, and you won’t need to start a new application unless the problem is serious or cannot be amended.
