In British or Irish company law, a company limited by guarantee is an alternative type of corporation used primarily for non-profit organisations that require legal personality. A guarantee company does not have a share capital, but has members who are guarantors instead of shareholders. The guarantors give an undertaking to contribute a nominal amount (typically £1) towards the winding up of the company in the event of a shortfall upon cessation of business. It cannot distribute its profits to its members, and is therefore eligible to apply for charitable status if necessary.
Like a private limited company, a company limited by guarantee must include the suffix "Limited" in its name, unless specifically excluded by law.
Common uses of guarantee companies include clubs, membership organisations (including students' unions, sports associations (such as the PGA European Tour), workers' co-operatives, other social enterprises, non-governmental organizations (NGOs) and charities (such as Oxfam). The railway infrastructure provider Network Rail, domain name registry Nominet UK, the UK Financial Services Authority (FSA) and IXP LINX (London Internet Exchange) are also companies limited by guarantee. Australia also has companies limited by guarantee, Cricket Australia being one example.
When incorporating multi-stakeholder organisations, this form is sometimes preferred over the industrial and provident society because company law allows multiple classes of member with separate voting constituencies.
