What percentage of new builds have to be social housing?

In the United Kingdom, social housing refers to the housing provided below market rates for low-income families, individuals, and vulnerable people. These are typically owned and operated by government agencies or non-profit organisations such as housing associations.  At least 10% of new build developments must be for social housing, however this can vary depending on the area. 

What are the UK government’s social housing policies and initiatives?

The UK government implemented several policies and initiatives to increase the supply of social housing and to improve the quality of existing social housing.

The UK government has sought to increase the supply of social housing by mandating that a certain percentage of newly built homes be designated as social housing. The current requirement is at least 10%, known as the "affordable housing requirement". This applies to developments of more than a certain size or over a certain number of homes.

The "affordable housing requirement" is to ensure that there is a sufficient supply of affordable housing for low-income families; particularly in areas where housing costs are rapidly rising - London and Manchester for example. By creating a mandatory percentage, the government is able to ensure that there is a sufficient supply of affordable housing for these families.

Due to the greater need for affordable housing, local authorities have set higher targets as the 10% threshold is the minimum requirement from the government. 

Another benefit of social housing on new build developments, is that it can help to create more mixed and diverse communities. By including social housing in new developments, it can bring together people from different socio-economic backgrounds, creating a more inclusive and cohesive community.

The UK isn’t the only country to have introduced policies and initiatives around social housing. In the Netherlands, the government requires that at least 25% of the newly built homes be designated as social housing.
