Changing Your Company Name — Process, Rules & Costs

Changing your company name is straightforward but there are rules to follow. The process involves passing a resolution, filing with Companies House and updating all business documentation.

Rules on Names

  • Must be unique — search BizLookup to check
  • Must end in "Limited" or "Ltd" (or PLC equivalent)
  • Cannot contain sensitive words (Royal, British, Authority) without approval
  • Cannot be offensive

The Process

  1. Pass a special resolution — 75% of shareholders must vote in favour
  2. File form NM01 — £8 online or £10 by paper
  3. Companies House reviews — usually 24-48 hours online
  4. Receive new Certificate of Incorporation — company number stays the same

After the Change

Update: bank accounts, HMRC records, stationery, website, contracts, insurance, domain names, social media and signage. The real cost of a name change is not the £8 filing fee but updating everything else.

Directed Changes

The Secretary of State can direct a name change if it is too similar to an existing name, misleading or offensive. You have 5 weeks to comply.

Cost

Companies House fee: £8 (online) or £10 (paper). Same-day: £30. Budget for updating bank, stationery and website. Use CalcPad to plan the transition costs.
