- Loss of existing housing is generally only acceptable where the housing is replaced at existing or higher densities with at least the equivalent level of overall floorspace. This includes the loss of hostels, staff accommodation, and shared and supported accommodation that meet an identified housing need, unless the existing floorspace is satisfactorily re-provided to an equivalent or better standard.
- Where loss of existing affordable housing is proposed, it should not be permitted unless it is replaced by equivalent or better quality accommodation, providing at least an equivalent level of affordable housing floorspace, and generally should produce an uplift in affordable housing provision. All such schemes are required to follow the Viability Tested Route (see Policy H6 Threshold approach to applications).
- For estate regeneration schemes the existing affordable housing floorspace should be replaced on an equivalent basis i.e. where social rented floorspace is lost, it should be replaced by general needs rented accommodation with rents at levels based on that which has been lost, and the delivery of additional affordable housing should be maximised. All schemes should follow the Viability Tested Route (see Policy H6 Threshold approach to applications).
The regeneration and intensification of London’s housing areas has been, and will continue to be, a key part of the evolution of London, and critical to meeting its housing needs. It is important that existing homes of all tenures are well-maintained and are of good quality as these will continue to be the bulk of London’s housing stock.

In some cases, regeneration will include the loss and replacement of homes and it is important that any such scheme is delivered with existing and new residents and communities in mind. This is particularly pertinent for estate regeneration, and any proposals for such schemes should take account of the requirements of the Mayor’s Good Practice Guide.
It is important to ensure that estate regeneration does not lead to the loss of affordable housing and that it delivers an uplift in affordable housing where possible. All estate regeneration schemes should go through the Viability Tested Route and maximise the delivery of any additional affordable housing. For the purposes of this policy, existing affordable housing floorspace includes both occupied and vacant floorspace.
Where a borough is redeveloping an estate as part of a wider programme then it may be possible to re-provide a different mix of affordable housing on the estate (taking account of the wishes of people who want to return to the estate) if the overall level of provision is maintained across the programme, (further guidance is provided in the Affordable Housing and Viability SPG). Where this is proposed, the Mayor will closely scrutinise proposals and will only agree to them where he is certain that the housing is being genuinely re-provided and that no better option is available. Given the impact of estate regeneration schemes on existing residents, it is particularly important that information about the viability of schemes is available to the public even where a high level of affordable housing is being delivered.
