From HM Revenue & Customs · Business Leasing Manual
The concept of the associated company of the relevant company is extended to encompass structures involving consortium relationships so that if a leasing business is carried on by a company in partnership that is owned by a consortium or a company that is a 75% subsidiary of a holding company owned by a consortium the connection rule will reach up through the consortium to encompass companies that are members of the consortium and companies that are associated with members of the consortium.
