We are proud of our strong 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’s 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 850,000 homes across the country.
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 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 engage decision makers on national and local policy, and its impact on housing associations and their residents.
Homes for the South West
Homes for the South West (H4SW) is the leading voice for affordable housing in the South West. The group is a not-for-profit coalition of twelve of the largest housing associations in the region who are committed to building the high quality, affordable and sustainable housing the South West desperately needs.
Members of H4SW own more than 250,000 homes, provide more than 500,000 people with a place to call home and contribute £1bn to the local economy every year.
Members of H4SW are continuing to identify and tackle the barriers to new housing across the South West, and making the case for new housing at a local, regional and national level.
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 a number of major developers, including Countryside Partnerships, Crest, Linden Homes, The Hill Group, Tilia Homes Vistry Group and Barratt.
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.
