Changing your Limited Company name
You can change the name of your limited company through a third party (such as a company formation service), or directly with Companies House.
If you're opting for the latter, you need to complete form NM01. There is a £10 fee payable to Companies House to file the form.
If you're trading as a limited liability partnership, you need to file form LL NM01. A £10 fee applies.
