Changing your UK limited company name after incorporation is a straightforward legal process handled through Companies House, provided you follow the correct shareholder approval and notification steps. Many early-stage founders decide to rebrand once their business direction becomes clearer or a better trading name emerges.
This guide walks you through the full procedure using official methods, explains what must be updated afterwards, and highlights practical considerations for e-commerce sellers and startup teams so you can complete the change without disrupting operations.
Why and when to change your company name
Founders often incorporate quickly with a placeholder name and later realise it does not reflect their brand, is hard to spell, or conflicts with an existing trademark. E-commerce sellers may also need to align the legal name with a strong domain or marketplace identity. The change must be made formally; simply trading under a different name does not alter the registered company name at Companies House.
Before starting, confirm the proposed name is available by searching the Companies House database and checking for similar trademarks on the Intellectual Property Office site. Availability can change daily, so verify on the day you file.
Deciding on the new name – practical checks
Choose a name that complies with UK rules: it must not be the same as an existing company, suggest a connection with government or local authorities unless approved, and avoid sensitive words without permission. For e-commerce businesses, test how the name appears on packaging, invoices and domain names.
Consider registering the new name as a trademark early if you plan to build significant brand value. Also secure matching web domains and social handles before announcing the change. These practical steps reduce the risk of future rebranding costs.
The shareholder resolution process
A limited company usually needs a special resolution passed by shareholders holding at least 75% of the voting rights. Hold a meeting or circulate written resolutions following your articles of association. Record the resolution in the company’s minute book and keep it with statutory records.
If your company has only one shareholder, the sole shareholder can pass the resolution. Document the decision clearly with the exact wording: “Resolved that the company name be changed from Old Name Limited to New Name Limited.” This resolution forms the legal basis for the application to Companies House.
Filing the name change with Companies House
Submit form NM01 (or use the online service if available) together with the special resolution. The form must be signed by a director or secretary. Companies House will process the change and issue a certificate of incorporation on change of name once approved. The change takes legal effect from the date on the certificate.
Check the current filing method and any associated costs directly on the Companies House website, as procedures and charges can change. After approval, the company’s registered name at Companies House is updated immediately, but your practical work to update records then begins.
Updating business assets, contracts and registrations
Notify your bank and update all account names and cheques. Inform HMRC, as they must record the new name against the corporation tax and VAT records if applicable. Review and amend every contract, supplier agreement, customer terms, insurance policies and leases. In many cases a simple letter or addendum stating the name change is sufficient, but some counterparties may require a formal novation.
For e-commerce operations, update your website footer, terms and conditions, privacy policy, invoice templates, packaging, Amazon or Shopify seller accounts, and any marketplace profiles. If you hold a registered office address or use a virtual office, confirm the new name appears correctly on all correspondence. Failure to update key documents can create confusion or legal gaps later.
GDPR, trademarks, insurance and ongoing compliance
Update your GDPR documentation and privacy notices to reflect the new legal entity name. Notify the Information Commissioner’s Office only if the change affects your registration details. Review your insurance policies; most providers will endorse the policy with the new name without charge, but confirm this in writing.
If you have trademark registrations in the old name, file an assignment or new application to protect the brand. Keep clear records of the resolution, certificate and all notification letters for future due diligence. Annual accounts and confirmation statements filed after the change should use the new name, although historic filings remain in the old name on the public register.
Common pitfalls and timeline
The entire process from resolution to certificate normally takes between one and two weeks if filed correctly, but allow extra time for updating every business asset. Common mistakes include using the new name before the certificate is issued, failing to update banking details promptly, or overlooking domain ownership transfers. Create a checklist covering banks, suppliers, customers, platforms, tax authorities, insurance and intellectual property.
Founders working from shared startup spaces such as Loomworks in Liversedge can discuss the practical side of rebranding with their operator mentor while completing the formal steps. Once all records are updated, the new name becomes part of everyday operations and the old name gradually fades from use.
Frequently asked questions
Can I trade under a different name without changing the company name at Companies House?
Yes. You can use a trading name or business name for marketing while the legal company name registered at Companies House stays the same. A trading name does not require a separate registration but must not mislead customers or infringe trademarks. The registered name still appears on official documents and contracts.
Do all shareholders need to agree to a company name change?
No. A special resolution requiring at least 75% of the voting shares is normally sufficient. Check your articles of association for any stricter rules. The resolution must be properly minuted and kept with the company’s statutory records.
How long does it take for Companies House to process a name change?
Processing times vary. Standard online or postal filings are usually acknowledged within days once all documents are accepted. Always check current service standards on the Companies House website, as times can change. The change is effective from the date shown on the new certificate of incorporation.
Do I need to tell HMRC when I change my company name?
Yes. HMRC should be informed so they can update their records for corporation tax, VAT and PAYE. In practice this is often done by submitting the new name on your next confirmation statement or by direct contact. Always confirm the latest notification method on GOV.UK.
What happens to existing contracts after a company name change?
Existing contracts generally remain valid but should be updated to avoid confusion. Many businesses send a short notice to counterparties confirming the name change while all other terms stay the same. Certain contracts may require formal amendment or novation. Review important agreements with suppliers, landlords and financiers.
