Daylight and Sunlight for PlanningDaylight & Sunlight for Planning

Most local authority Unitary Development Plans now incorporate a requirement for analysis showing how a development is likely to affect the light level and amenity of neighbouring owners, which is usually heavily weighted towards neighbouring residential occupiers. The criteria applied are detailed within the Building Research Establishment’s (BRE) Site Layout Planning for Daylight and Sunlight (2011) and British Standard 8206-2. Generally speaking, the tests examine daylight, sunlight and overshadowing (DSO) of neighbouring properties.

Consequently it is essential that you obtain a report from an experienced consultant who understands the relevant tests and how to interpret the results in a manner which is balanced and considers the often dense urban landscape of our towns and cities. As experienced practitioners in this complicated area of consultancy, we would be pleased to assist you further. We also recommend reading our more detailed guide which can be found found here.
