Frequently Asked Questions

How do I file an NM01 form to change my company name at Companies House?

Complete the NM01 form through Companies House WebFiling, or download and post the PDF version. Attach the correctly-worded special resolution. Our NM01 generator saves time by filling in details and formatting your documents to Companies House standards.

How long does a company name change take in the UK?

Most online filings are processed within 1–2 working days. Postal filings may take up to two weeks. Prompt submission of clear documents helps ensure the fastest results.

Do I need shareholder or director approval to change the company name?

Yes. The board must initiate and approve the proposal, but the actual change requires at least 75% of shareholders to vote in favour via a special resolution.

What is a special resolution and how do I write one?

A special resolution is a shareholders’ agreement (minimum 75% approval) for key company matters. The exact legal wording is vital—our AI template builder ensures your special resolution meets Companies House criteria.

Can I change the trading name when changing my registered company name?

You may change your trading name at the same time, but all statutory records, contracts, and accounts must always show your company’s correct formal name.

Can I reserve a company name before changing it?

You cannot “reserve” a UK company name, but you can check availability and register matching domains or trademarks in advance.

What are the restrictions on new company names?

Companies House restricts names with sensitive words, misleading terms, offensive language, or close similarity to existing entities. Check their guidance or use our automated search to screen your options.

What if I forget to update HMRC or banks after changing my company name?

Delays or suspensions in accounts, payroll, and tax filings can occur. Immediate notification is essential.

Will a name change affect existing contracts or obligations?

The company’s legal identity remains the same, so contracts remain effective—but you must notify all parties to avoid confusion or operational issues.

Do I need a solicitor, or can I change our company name myself?

Most companies complete the process themselves using clear online tools—no need for a law firm if you follow UK Companies House rules. Our AI-driven templates and risk checks guide you through every stage.
