Daylight & Sunlight Assessment

A Daylight & Sunlight Assessment is a detailed technical analysis and report that evaluates the potential environmental impact on daylight, sunlight and overshadowing by a proposed development based on appropriate industry standards (BRE). This is different from a Right to Light assessment which is a civil law matter rather than a planning issue.

There are several circumstances in which surveyors may be asked to deal with daylight and sunlight matters. These may include:

  • advising an adjoining owner who has concerns regarding a potential development adversely affecting their daylight and sunlight
  • assisting a developer wishing to assess impacts of daylight and sunlight on a development scheme or wishing to determine the maximum size of a potential development
  • advising on application of planning policy in respect of daylight and sunlight; and
  • acting for a developer at planning committee or planning inquiry.
