Understanding BT Group’s Ownership and Subsidiary Structure

Knowing who owns which part of a company is important to understand how it works globally. Our corporate hierarchy data shows the links between parent companies and their subsidiaries, making it easier to see control, structure, and risks in any corporate group. For multinational firms like BT Group, this data is useful for compliance, market research, and data management. CompanyData.com offers verified ownership records on over 380 million companies worldwide, giving a clear picture of company relationships across borders and sectors.

How BT Group’s Global and Local Headquarters Are Organized

CompanyData.com classifies companies using a three-level system: Global headquarters, National headquarters, and Local headquarters. This shows how a company’s different parts connect to each other.

Our three-level structure

  • Global Headquarter — BT Group’s main global headquarter is in London, United Kingdom, acting as the top company in its worldwide network.
  • National Headquarters — These manage operations at the country level. Examples for BT include BT USA and BT Singapore subsidiaries.
  • Local Headquarters — These operate regional offices or divisions, often managing local customer service centers, infrastructure, or sales hubs.

Every company entity has its own unique ID to link it to others, making the ownership structure clear and easy to analyze.

How control is identified

Control depends on ownership stake. If a company owns over 50% of another, it’s a controlled subsidiary. Our data focuses on these majority-owned companies to clearly show how global groups like BT are made up.
