  John Pitcher: Will a .org, or a .org.uk or a .net domain do OK for a small UK business?
  
  For a new customer, the .co.uk domain that matches their business name has gone. (There is no website for the name at the moment - but my customer will not be looking to try to pay a premium price for the domain.)
  
  For a company with a name of XYZ Cleaning Services
  
  I could either get a xyzcleaningservices.net or xyzcleaningservices.org.uk or xyzcleaningservices.org
  or
  xyzcleaningcompany.co.uk - note this is company not services
  
  I favour one of domains that matches their company name (rather than having a different domain name to the company name given in all of the directories etc), but am not sure if these extensions have the same weight in Google?

  Dave Elliott: while not restricted(i think) .org.uk is mainly and preferably used for charities and non commercial entities so i wouldn't use it for a business.
  
  personally, out of the three i'd use the .net
