Regulations made under the Companies Act 2006 require an LLP to display its name at its registered office and other places of business, on business documents and on websites. The purpose of the regulations is that the legal identity of every LLP should be revealed to anyone who have, or may wish to have, dealings with it.

Every LLP, unless it has been continuously dormant since incorporation, must display a sign with its registered name at:

• its registered office
• any inspection place
• at any location at which it carries on business (unless it is primarily used for living accommodation) or if the LLP’s activities are likely to attract violent objections.

It must also include its registered name in all business communications (hard copy and digital).

An LLP must also display a sign with its LLP name:

• in characters that can be read with the naked eye, and
• in such a way that visitors to that office, place or location may easily see it at any time continuously, but if the location is shared by 6 or more LLPs , each such LLP must either display its registered name for at least 15 continuous seconds at least once in every 3 minutes, or make its registered name available for inspection on a register by any visitor.

An LLP must include its registered name in all forms of business communications and documents whether in hard copy or digital.

This includes:

• business letters, notices and other official publications
• business emails
• bills of exchange, promissory notes, endorsements and order forms
• cheques purporting to be signed by or on behalf of the LLP 
• orders for money, goods or services purporting to be signed by or on behalf of the LLP
• bills of parcels, invoices and other demands for payment, receipts and letters of credit
• all other forms of business correspondence and documentation.

Every LLP must disclose its registered name on its websites, and on any part of a website relating to it which it has authorised. The LLP doesn't need to include the LLP name on every page, but it must be visible and easily read.

There are 2 exceptions:

1. An insolvent LLP (one which a liquidator, administrator, or administrative receiver has been appointed) is not required to display its registered name at any premises which are also the place of business of those insolvency specialists.
2. If every member of the LLP is one whose residential address cannot be disclosed by the registrar to a credit reference agency, then the LLP does not have to display its registered name at any place at which it carries on business. This exception does not extend to the LLP’s registered office or inspection place for the LLP’s records.

On all LLP business letters, business emails, order forms and websites, it must display:

• the part of the UK in which the LLP is registered (England and Wales, Wales, Scotland, or Northern Ireland)
• the LLP’s registered number
• the address of the LLP’s registered office
• where the LLP name ends with the abbreviation LLP, llp, or the Welsh equivalent, the fact that it is a limited liability partnership or the Welsh equivalents.

If anyone with whom the LLP deals in the course of business makes a written request for:

• the address of its registered office
• the address of any place of inspection
• the type of LLP records kept at the registered office or inspection place,

the LLP must provide the information in writing within 5 working days of the receipt of that request.

If the LLP includes the name of any member on its business letters, other than in the body of the letter or as a signatory to it, it must include all the members’ names. It cannot be selective about which names to include.

However if the LLP has more than 20 members providing it keeps a list of all the members’ names at its principal place of business, and the document states that the list is available for inspection, it need not show the members’ names.

If the LLP is being wound up, is in administration, receivership or a moratorium is in force in respect of its debts, then every invoice, order for goods, business letter or order form (in hard copy, digital or any other form) must contain a statement that the LLP is being wound up.
