These are the specific rules for the .ltd.uk and .plc.uk SLDs, administered directly by us. They form part of and, in the case of conflict, take precedence over the Rules.

10.2.Requirements on Applicants

10.2.1. No Third Level Domain shall be registered in either the .ltd.uk or .plc.uk SLD unless all the requirements of this section are met.

10.2.2. All registrants in .ltd.uk and .plc.uk must be incorporated companies (not partnerships of any type or unincorporated companies) listed on the index of company and corporate names ('the Names Register') maintained under section 714 of the Companies Act 1985 (or later equivalents); and

10.2.2.1. (for .ltd.uk domains) must be entitled to use 'Limited', 'cyfyngedig', 'ltd.' or'cyf'. in their corporate name; or

10.2.2.2. (for .plc.uk domains) must be entitled to use 'Public Limited Company', 'Cwmni cyfyngedig cyhoeddus', 'Plc.' or 'ccc'. in their corporate name.

10.2.3.1. is a company of the appropriate type for the SLD; and

10.2.3.2. is not already the registrant of a Domain Name in that SLD.

10.2.4 No Domain Name shall be registered in either .ltd.uk or .plc.uk SLD unless the Third Level Domain can be derived from the official company name of the applicant using the algorithm in Clause 10.3 below. If the algorithm of Clause 10.3 below does not generate a name permitted by the Rules, your application to register a Domain Name within the .ltd.uk or .plc.uk SLDs will be refused.

10.2.5 Applications for Domain Names in the .ltd.uk and .plc.uk SLDs must state the full name of the company as registered and the company registration number, and the applicant must be prepared to provide proof of the company's incorporation.

10.2.6 If we become aware that the registrant company has changed its name, been dissolved, or otherwise removed from the list of active names on the Names Register, we may transfer, cancel, suspend or amend the Domain Name in accordance with our terms and conditions and by sending a notice in writing to the last known registered office of the company, or without notice if the registrant company has been removed from the list of active names on the Names Register.

10.3. Selection of Domain Name

10.3.1. The following algorithm is intended to assist you to convert your company name to a Domain Name capable of registration within either the .ltd.uk or .plc.uk. The steps must be carried out in the order given. All steps must be carried out, but some steps give the option of making no change. This algorithm is not guaranteed to generate a Domain Name capable of registration with us, i.e. the algorithm may only produce a name which is still in an inappropriate format or has already been registered, and in these cases the name will not be registered to your company.

10.3.2. The following terms or abbreviations are removed from the end of the company's name:

* limited
* public limited company
* cyfyngedig
* cwmni cyfyngedig cyhoeddus
* ltd
* plc
* cyf
* ccc

10.3.3. Each occurrence of the characters "&" and "+" is replaced by (the separate word) "and"
10.3.4. All punctuation marks are removed, including the following
* apostrophe
* quotation marks
* commas, full stops, colons, and semicolons
* exclamation, question, number, and currency marks
* parentheses, (square) brackets, and braces

10.3.5. Remove any marks on or around the letters, for example accents, leaving only the "base letter", i.e. the letter without any marks in or around the letter.

10.3.6. If at this point the name contains only spaces, no Domain Name capable of registration with us may be derived. Otherwise the remaining steps in this Clause 10.3 are to be carried out.

10.3.7. If the company name begins with any of the following words or phrases, they may be removed:

* the

For the avoidance of doubt, this is done once only.

10.3.8. If the company name ends with any of the following words or phrases, they may be removed:
* company
* cwmni
* and company
* a'r cwmni

and any abbreviation of these (such as "co", "and co", or "cpy")
For the avoidance of doubt, this is done once only.

10.3.9. All spaces at the beginning and end of the Third Level Domain are removed and the gaps between words in the Third Level Domain are reduced (if applicable) to single spacing.

10.3.10. All remaining spaces must either be removed or changed to hyphens (one hyphen per continuous string of spaces). The remaining Third Level Domain must be compatible with section 5.2 of the Rules. For the avoidance of doubt the restrictions in sections 5.5 and 5.6 do not apply to .ltd.uk or .plc.uk domains, provided that there is at least one number or letter (but no hyphens) in the name.
