Daylight, Sunlight and Overshadowing

Town Planning Consideration

Daylight and Sunlight are types of amenity enjoyed by existing neighbours or future occupiers of a proposed development. Local Planning Authority policy will typically necessitate a formal report considering potential impacts to existing neighbours and the quality of provision within proposed dwellings in order to validate a submitted planning application.

Daylight, Sunlight and Overshadowing matters can and do often form reasons for refusal to grant planning permission. As such, they can become one of the main considerations in a subsequent appeal.

In addition, there are Daylighting credits available under Building Research Establishment Environmental Assessment Method (BREEAM) rating and certification, which apply to a wide range of buildings types.

This can help achieve an ‘Excellent’ or ‘Outstanding’ BREEAM rating, thereby signifying high sustainability performance to potential tenants or purchasers.
