We are proud of our strong, open partnerships with national and local government, Homes England, house builders, businesses, investors, community and charitable groups and many more.
These partnerships include:
The G15
SNG is part of the G15 group of London's largest housing associations 
.
The G15 members house one in 10 Londoners and are the largest providers of affordable homes in the capital. They build a quarter of all London’s new homes and collectively own or manage more than 600,000 homes.
G15 housing associations have the shared purpose of helping people in housing need, building more homes, and creating communities where people can realise their potential.
The Consortium of Associations in the South East (CASE)
The Consortium of Associations in the South East (CASE) is a research group of 12 major housing associations, who together own and manage homes across the South East of England.
The objective of the group is to share thinking on best practice, as well as to prepare and commission research on matters of common interest.
The group’s research aims to educate decision makers on how national and local policy will affect housing associations and their residents.
Sovereign Development Consortium (SDC)
The Sovereign Development Consortium (SDC) is an alliance of five landlords and housing providers in the south and south west, including SNG.
The consortium's regional overview and strong relationships with national and local developers mean it can build houses where they are needed most, including both rural and urban schemes. The SDC also tailors its developments to fit in with local requirements - such as local lettings, local labour, supported housing and resident involvement.
Working together, SDC members can keep procurement costs down, increase efficiencies, bid effectively for funding, and share best practice when building homes.
Since forming in 2004, the SDC has exceeded government targets with a focus on:
- building quality homes faster
- building more cost-effectively
- making sure homes are energy efficiency
- having the right mix of tenures, including rent, shared ownership, and outright sale
- creating attractive estates with designs that cut crime and traffic, and provide options for housing to be altered or extended for changing family circumstances.
Source Development Partnership
Source Development Partnership is a consortium of developing housing associations across the south and south west.
Joint Ventures
Formal joint ventures include several site-specific redevelopment partnerships with West Berkshire Council and with a number of major developers, including Countryside Partnerships, Crest, Linden Homes, The Hill Group, Tilia Homes and Vistry Group.
Shared Ownership Council
We are a founding member of the Shared Ownership Council , formed in 2024 and stemming from a strategic review of the future of homeownership. The review showed a general recognition of the potential of shared ownership to broaden access to homeownership. The Council’s aim is to improve the consumer experience of shared ownership so that it can meet its true market potential.
Other partnerships
Homelessness services
As well as working closely on relevant issues with local authorities, health services and other partners across all the areas where we have homes, we have more formal partnerships with a number of local authorities to deliver homelessness services. You can read more here about our approach and Housing First successes.
Accommodation for employees
If you’re an employer we could be the solution to your staff housing needs as partnering with us gives employees priority access to some of the best value homes in London and the East of England. We work with NHS trusts, the British Transport Police, and other large organisations to provide quality accommodation for their employees.
