A private company must have at least one director and a public company two: sec152 CA 2006. There is no statutory maximum number of directors. At least one director must be a natural person: sec155. A person aged 16 or under cannot be a director: sec157.
By new sec156A, sec156B and sec156C of CA 2006 (inserted by sec87 of the Small Business, Enterprise and Employment Act 2015) only natural persons may be company directors. This is subject to any regulations made under these provisions, though these must provide that a company must have at least one natural person as a director. Any corporate director in office when these provisions come into effect must cease to be a director 12 months after the provisions come into effect.
Since April 2008 there is no requirement for a private company to have a company secretary, although one can still be appointed.
The Model Articles (for companies registered after 1.10.2009) provide that the minimum number shall be one director.
Table A, article 64 provides that unless otherwise determined by ordinary resolution, the number of directors (other than alternate directors) shall not be subject to any maximum but shall be not less than two.
