What are Supplementary Planning Guidance’s & Supplementary Planning Documents?

The role of Supplementary Planning Guidance (SPG) and Supplementary Planning Document (SPD) is to provide supplementary information to help guide the drawing up of development proposals and of planning applications.


Supplementary Planning Guidance is prepared within the context of Local Plans to assist individuals submitting planning applications. Supplementary Planning Guidance does not form part of the Local Plan, but may be taken into account as a material consideration when the Council determines planning applications. Over time SPGs will be updated and revised as SPDs within the context of the Planning and Compulsory Purchase Act 2004.


SPDs form part of the Local Development Framework (LDF) and are intended to expand upon policy or provide further detail to policies in Development Plan Documents (DPD), but do not have DPD status. These documents can demonstrate how policies can be taken forward. They do not include land allocations or policies which should be subject to independent examination.


An SPD is not part of the statutory Development Plan, unlike the DPD. However, the SPD will form part of the Local Development Framework, and will be an important consideration in determining planning applications. As well as this, it has greater weight than SPG because it has complied with the requirements for community involvement and Sustainability Appraisal and is in conformity with a development plan policy.
