Can You Change a Company Name Quickly in 2026?

You can change a UK limited company name online via Companies House and often register the new name within 24–48 hours if the application is valid and the name is available.

How do you apply to change a company name through Companies House?

You apply by filing form NM01 (paper) or using the Companies House WebFiling service (online), and pay the appropriate fee; online applications complete fastest.
Use the WebFiling service to submit a change request. Provide the proposed name, the company number, and the date the resolution was passed. Pay the current fee: £8 for standard online processing, £10 for same-day service by post if required. Companies House validates the name against sensitive and prohibited lists and confirms availability. If validation passes, the registrar issues a Certificate of Incorporation on Change of Name, which legally records the new name.

What documents must a company pass before Companies House will accept a name change?

A limited company must pass a board resolution or special resolution, file supporting minutes or written resolution evidence, and include the effective date for the change.
Private companies commonly use a special resolution (75% of votes), while public companies use an ordinary resolution, where required by articles. Provide the resolution number and date when filing. If articles require director approval, include the relevant minute extract or signed written resolution. If the change involves sensitive terms (e.g., “Bank”, “Royal”), attach formal approvals from regulators or ministers.

How long does Companies House take to process a name change?

Standard online processing usually completes within 24–48 hours; postal submissions take up to five working days, and same-day postal service is available for an extra fee.
Processing time depends on accuracy and name checks. Companies House checks for identical or similar names, restricted words, and potential trademark conflicts. Rejections usually occur for identical names or use of restricted words without approvals. If rejected, Companies House returns the application with reasons and you must resubmit with a revised name or supporting documents.

What naming rules will Companies House apply when validating a new name?

Companies House enforces uniqueness, prohibits offensive terms, and restricts sensitive words that require approvals (for example, “bank”, “assurance”, “Royal”).
The registrar compares the proposed name to the register and takes phonetic and visual similarity into account. The name cannot be the same as an existing company number or too like one. If the name uses restricted words, supply regulator approval letters. Avoid characters that confuse, such as misleading punctuation or foreign language equivalents of restricted terms.

How do you check whether a proposed company name is available?

Search the Companies House register online, check trademark registers (UKIPO), and run a web domain availability check to reduce conflicts.
Start with the Companies House WebCheck or beta service to identify identical names and similar entries. Search the UK Intellectual Property Office for registered trademarks covering your industry. Check domain names and social handles to protect brand consistency. Document your searches before filing to support due diligence.

What practical steps speed up a company name change?

Prepare the signed resolution, confirm name approvals (if needed), verify availability, and file online using WebFiling with the correct fee to obtain the fastest processing.
Draft and circulate the resolution to shareholders or directors. Gather regulator approvals for restricted words in advance. Ensure the proposed name follows punctuation and character rules. Use the service page process to link company actions with post-filing updates, for example, updating statutory registers and stationery.

How do you update records after Companies House confirms the new name?

Update the company’s statutory registers, HMRC records, bank accounts, contracts, and marketing materials using the Certificate of Incorporation on Change of Name as evidence.
Send copies of the certificate to banks to update accounts and to HM Revenue & Customs to update tax records. Notify customers and suppliers via formal letters. Amend contracts where required to reflect the new name; some contracts require novation. Update company stationery, websites, and social media profiles to maintain brand clarity.

What costs and compliance actions follow a name change?

Expect Companies House fees (£8 online), potential legal fees for trademark clearance, and administrative costs to update corporate documents and third-party records.
Budget for trademark searches and filings if you plan to protect the new name. Include accountancy or company-secretarial time to update registers, update the PSC register, and file any necessary returns. Some banks charge fees for reissuing account documentation. Keep electronic and paper copies of the certificate for audit and compliance tracking.

When is changing a company name not advisable?

Avoid changing the name during ongoing litigation that uses the company name, when trademark conflicts exist, or when customer recognition loss would harm revenues.
Legal proceedings that reference the company name may require court approvals or create administrative confusion. Active trademark disputes risk injunctions after a change. High customer recognition means rebranding costs and sales disruption. Evaluate brand equity, search costs, and legal exposure before filing.
