Our team prepares these reports under RICS regulation from our London office at Boundary Row, SE1, with BRE 209 (2022) as the working reference. The practice has been delivering daylight and sunlight reports since 2004. Where the scheme involves building over an existing property, airspace development advice sits 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. No Sky Line and sunpath studies sit alongside where geometry or seasonal access matter, with the larger Uxbridge and Hayes regeneration zones requiring particular attention to cumulative effects.
The report sets out methodology, figures, and design rationale where the numbers run below BRE 209 reference values. Typical turnaround is 2 to 3 weeks from instruction. A free initial assessment confirms scope before any fee is set. This is a bespoke surveying service shaped to each scheme.
BRE 209 reference values are guidance, not pass or fail. 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 scope before the planning programme commits to a particular form or massing strategy for the scheme.
