Affordable housing delivery and planning obligations

Our housing enabling team (HET) reviews new affordable housing in Harrow.  The team aims to provide as much affordable housing as possible.

We are helped to achieve this by:

  • The Greater London Authority (GLA)
  • Registered Providers (RPs) and
  • Private developers.

This is in line with the Town and Country Planning Act 1990, Section 106.

Section 106 (S106) agreement

A S106 agreement is a legally binding agreement or planning obligation. It is between a local planning authority, like us, and a property owner.

The purpose of a S106 agreement is to reduce the impact of the development on our local community and infrastructure.

The agreements secure contributions to affordable housing. They also cover other services, such as:

  • Community facilities
  • Public open space
  • Transport improvements
  • And/or affordable housing.

We aim to develop affordable housing from schemes that can can provide 10 residential units or more. This is in line with the London Plan and Local Development Framework (LDF) Policy.

For more information see our Planning obligations SPD.


You need to submit a financial viability assessment. This is to show how much affordable housing can be delivered on the scheme. Talks should take place before an application is submitted.

The HET advises on the type of affordable housing needed. They also provide details of suitable RP partners working in Harrow.
