Daylight and Sunlight Assessments for Planning Applications
Daylight and sunlight assessments are frequently required by planning authorities where new buildings or extensions may affect the natural light received by neighbouring properties.
Our consultancy prepares detailed daylight and sunlight reports in accordance with the industry guidance set out in the BRE Site Layout Planning for Daylight and Sunlight, commonly referred to as BRE BR-209.
These assessments help demonstrate that a proposed development provides acceptable daylight conditions and does not cause significant loss of light to surrounding buildings.
Our daylight and sunlight assessment services include:
● Daylight analysis to neighbouring windows
● Sunlight analysis to gardens and open spaces
● Vertical Sky Component (VSC) calculations
● Daylight Distribution testing
● Annual Probable Sunlight Hours (APSH) analysis
● Overshadowing and shadow path modelling
● 3D modelling of proposed developments
● Planning-ready technical reports for submission
Where daylight impacts are identified, we also provide design recommendations to help optimise layouts and reduce planning risks.
Biodiversity Net Gain (BNG) Reports for Planning
Biodiversity Net Gain is now a mandatory planning requirement in England under the Environment Act 2021, requiring most developments to deliver at least 10% net gain in biodiversity value.
A BNG report demonstrates how a development will improve biodiversity compared with the existing site condition.
Our BNG consultancy services include ecological site surveys, biodiversity metric calculations and habitat enhancement strategies designed to achieve planning compliance.
Our BNG services include:
● Habitat surveys and ecological baseline assessments
● Biodiversity metric calculations
● Habitat condition assessment
● Biodiversity Net Gain strategy reports
● Habitat creation and enhancement plans
● Native planting recommendations
● Landscape and ecological mitigation proposals
● BNG metric spreadsheets for planning submission
Right to Light Assessments
Right to Light is a legal property right that protects access to natural light through windows in neighbouring buildings.
Where developments may affect neighbouring light levels, a Right to Light Assessment may be required to evaluate potential legal risks.
Our right to light consultancy services analyse how proposed developments may affect neighbouring light levels and whether there is potential infringement of established rights.
Our Right to Light services include:
● Initial desktop right to light risk assessments
● Detailed daylight modelling analysis
● Light obstruction calculations
● Identification of potential legal exposure
● Design mitigation advice
Early right-to-light analysis allows developers to identify risks before construction or planning approval, helping avoid costly disputes later in the project.
