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.

News and Comments Residents’ Group

The G15 Residents’ Group is calling for government to pilot a new approach to shared ownership that could make staircasing more affordable, help more residents achieve full home ownership and unlock investment in new social and affordable homes. Read their letter to the Housing Minister here.

News and Comments Publications

G15 has published, ‘A city that works for everyone: How social housing supports London’s economy and communities’ a new report exploring the contribution social housing makes to the capital.

Drawing on analysis from the Centre for Economics and Business Research (CEBR), the report estimates that social housing residents contributed £27.8 billion to London’s economy in 2024. It also finds that almost two-thirds of employed social housing residents work in key worker roles across sectors including health and social care, education, transport and retail.

The report highlights the wider role of social housing in supporting communities, strengthening public services and enabling people to remain connected to work and local support networks across London.
The report is available to read now.
