Occupational pension schemes (www.practicallaw.com/8-107-6900) must identify one of the participating employers (www.practicallaw.com/6-206-1084) as the principal employer. It is usually the employer establishing the scheme or the parent company in a multi-employer scheme (www.practicallaw.com/3-206-1085). The scheme’s principal employer will have special powers and duties under the scheme’s rules, for example, it may have power to agree amendments to the scheme or trigger a winding-up of the scheme.
