Daylight, Sunlight and Overshadowing are planning considerations which differ from Rights of Light.
Planners from the local council may be concerned about the potential loss of light to neighbouring properties as a result of new developments. Homeowners may fear they will suffer a loss of daylight or sunlight if their homes, yards or gardens are overshadowed by new developments. Utilizing guidelines set forth by the Building Research Establishment’s guide to good practices, we also measure your Vertical Sky Component and Average Daylight Factor to guarantee you meet all requirements.
The success of a planning application will rely on a number of reports being submitted.
Many developments, particularly in urban areas will pose light limitations to surrounding residential buildings and the scheme itself. Daylight, Sunlight and Overshadowing assessments will be required by Local Authority as a means of establishing proposed light levels. Here at Anderson Wilde & Harris we have a number of services to assist with your requirements.
When do I need a Daylight, Sunlight and Overshadowing report?
Planners from the local council may be concerned that large developments or developments in built up areas will have an impact on the light in the neighbouring properties. If they are, then they may request a Daylight, Sunlight and Overshadowing report to demonstrate that the neighbours won’t be affected.
Is a Daylight, Sunlight and Overshadowing report different to a Rights of Light report?
Yes. A Daylight, Sunlight and Overshadowing report will address the planning considerations, whereas Right to Light is common law right. During the planning process planners are usually only concerned with planning considerations.
How much does a Daylight, Sunlight and Overshadowing report cost?
This depends on the size of the development and the number of neighbouring properties that need to be considered as part of the assessment. We provide two types of assessments and these are quoted on a case by case basis. An initial assessment to give you our professional opinion about your potential loss of light. Next, a full Rights of Light assessment including 3D Modelling and software analysis is completed.
Can you tell me how much compensation I should be awarded?
This requires a full Rights of Light survey to be undertaken, either by yourself or the developer. We can calculate and negotiate the best compensation for you, so that you are happy to release your Right of Light.
Do you provide accurate results with 3D modelling?
Yes. With the aid of bespoke Rights of Light software we effectively build your development and local environment on the computer, and then calculate the exact amount of light lost to the neighbouring properties.
All our reports follow the Building Research Establishment (BRE) Site Layout Planning for Daylight and Sunlight Guidance note. They test a range of methodologies including Vertical Sky Component (VSC), Average Daylight Factor (ADF) and Annual Probable Sunlight Hours (APSH).
