Our team prepares these reports under RICS regulation from our Hampshire office, with BRE 209 (2022) as the working reference. Site attendance across the Winchester district runs faster than for London-led practices, and the practice has been delivering daylight and sunlight reports across the South Coast and East of England since 2004. Where works cross a shared boundary, party wall services sit alongside the daylight piece.
Vertical Sky Component covers light to windows. Annual Probable Sunlight Hours covers sunlight to habitable rooms with relevant orientation. Overshadowing analysis tests amenity space under the 21 March sun position recommended in the guidance. Sunpath studies sit alongside where seasonal access matters, particularly on tight historic plots where orientation drives much of the result.
A typical turnaround is 2 to 3 weeks from instruction. Calls are answered by a qualified surveyor, and a free initial assessment sets out scope before any fee is committed. This is a bespoke surveying service shaped to each scheme.
BRE 209 sets reference values, not legal thresholds, and shortfalls can be justified where the context supports the design. Reports are turned around in 2 to 3 weeks. The free initial assessment is the way in for borderline cases or for early advice on whether a full study is needed at this stage of the project.
