Supplementary Planning Documents and Guidance

To help support decisions on planning applications, we've compiled a series of supplementary planning guidance (SPG) and supplementary planning documents (SPD) to provide greater detail on our strategic policies.

Planning obligations

Adopted 10 July 2014

This Supplementary Planning Document (SPD) provides guidance on the use of planning obligations in Hillingdon for those involved in the submission and determination of planning applications. 

This new version of the SPD replaces the previous version published in July 2008 and explains how planning obligations and the Community Infrastructure Levy operate alongside each other.

Despite changes to the infrastructure funding regime, planning obligations will continue to provide a valuable means of securing site-specific mitigation required to make developments acceptable in planning terms. For example, this could include ensuring developments meet site-specific, open-space requirements or provide sufficient levels of affordable housing. 

In accordance with Regulation 16(b) and 16(c) of the Town and Country Planning (Local Development) (England) Regulations 2004, any person aggrieved by a Supplementary Planning Document (SPD) may apply to the High Court for permission to apply for judicial review of the decision to adopt the SPD. And such application must be made promptly and no later than three months after the date on which the SPD were adopted.
