We are G15

The G15 is made up of 11 of London’s largest not-for-profit housing associations. Collective leadership is provided by the Chief Executives of each member organisation.

As an informal collective, we work collaboratively, sharing insight, aligning priorities, and developing best practice amongst members.

The Chair of G15 rotates every two years and is drawn from the Chief Executives of our members. The G15 is currently chaired by Ian McDermott, Chief Executive of Peabody. The vice-chair of G15 is Clare Miller, Group Chief Executive of Clarion.
