Daylight, Sunlight, Overshadowing & Amenity Assessment

Internal and External Lighting Impact Survey & Assessment  

We specialise in daylight and sunlight assessment as well as external lighting impact assessment to support planning applications. We produce technical daylight assessment and sunlight assessment in line with the appropriate BRE guidance to comply with local planning requirements.

Natural light inside buildings is immensely important for comfortable living and working. We like and want natural light in our kitchens, and at our desks and other amenity spaces. People like to have a window seat and most people thoroughly dislike a windowless room. The amount of natural light that a window lets in depends upon what is outside that window, and particularly upon the proximity of other buildings.

The legal system recognises the value of natural light inside buildings, but because available space is finite it has to strike a balance between the importance of light and the importance of the construction of homes and offices, and the provision of jobs, schools and other essentials.

Local planning authorities consider the effect of new buildings upon existing structures, the planning system gives protection but not rights. Thus when planning permission is applied for, a local planning authority will want to see evidence of the effect it will have upon the neighbouring properties, including, in many cases, the light and other amenities that those properties currently have. Where a residential property is involved the local planning authority may use Site layout planning for daylight and sunlight assessment based on BRE Guidances.

Our daylight and sunlight assessment consultants provides a range of services covering all aspects of technical design and neighbouring impact assessment services for Skylight, Daylight, Sunlight along with Artificial Electrical Lighting. As part of this, our dedicated Lighting Team can provide expert advice on a variety of lighting issues.

We cater to both domestic structures such as independent houses, apartment complexes and non-domestic structures such as educational buildings, commercial complexes, mercantile spaces, storage and industrial buildings.
