About The 100 Group

About Us

The 100 Group represents the views of the Finance Directors of FTSE 100 and several large UK private companies.

Our member companies represent around 87% of the market capitalisation of the FTSE 100. They collectively employ approximately 6% of the UK workforce and in 2019/20 paid or generated taxes equivalent to around 11% of the total UK Government receipts.

The overarching objective of The 100 Group is to promote the competitiveness of the UK for UK businesses, particularly in the areas of tax, reporting, pensions, regulation, capital markets and corporate governance for the benefit of its members, the UK economy and long-term growth of the UK.

The 100 Group is registered on the European Transparency Register. For more information, see here.

Our structure

The 100 Group is organised through a structure of committees. Each committee meets once a quarter to debate emerging topics on the agenda of Finance Directors.

The main committee determines the overall strategic direction of The 100 Group, and delegates responsibility for action to the sub-committees. Each sub-committee is chaired by a member of the main committee. Committee meetings are held in private, and guests are invited by the committee

Our Members

Our members are drawn principally, but not exclusively, from Finance Directors of FTSE 100 companies. Membership is by invitation only.

The views expressed by The 100 Group are informed by the members of the committees and the membership as a whole, but they are not necessarily the views of individual members or their respective employees. 

The 100 Group’s membership is updated once a quarter. Additionally, The 100 Group invites a number of individuals to become honorary members, principally former chairman. 

Membership Requirements

Membership is by invitation and is at the discretion of our Main Committee. We would be interested to consider any application from entities that are UK headquartered and are listed on the FTSE 100 based on equity shares or of equivalent size (particularly by relevant market capitalisation metrics, turnover, employee numbers) to the FTSE 100. Also, if you have an active interest in the UK business community.

If you believe you are eligible for membership and would like to contact us further, please complete the application form.


The 100 Group can trace its origins back to 1975, when a group called The 100 Group of Chartered Accountants was formed. At that time, members were drawn more widely than Finance Directors. 

The first Chairman was Arthur John, and the members quickly decided that it should be a working organisation rather than a social group. The earliest topics covered related to the report of the Sandilands Committee, a UK Government inquiry into inflation accounting. 


In 1978, Leslie Pincot (Esso) became chairman, and shortly thereafter it established three standing committees to consider emerging topics. At this time, the group was heavily involved in the role and function of Audit Committees as well as establishing a group to consider the skills and knowledge required by Finance Directors. Accounting standards and tax legislation dominated activities and both have remained at the forefront of the Group’s activities ever since. 


Under Ian Tegner’s (Midland Bank) Chairmanship from 1989, the membership criterion was altered. Whereas previously a number of Chief Executives and Company Chairmen had been members, changes were implemented to restrict members to those holding a current role in finance. It was shortly after this move, that the group became known as the 100 Group of Finance Directors. 


Throughout the 1990’s the group lobbied on a number of high-profile activities such as pension reform and changes to accounting standards. It also played a leading role in the development of the Cadbury Report. 


More recently in the 2000’s, the group has played leading roles in the acceptance and development of International Accounting Standards, turning its attention to Europe and beyond. The current Chairman is Julia Wilson (3i) who succeeded Brian Gilvary (BP) in June 2020. The group’s activities continue to be as relevant and important today, as they have ever been.
