Our team prepares these reports under RICS regulation from our London office at Boundary Row, SE1, with BRE 209 (2022) as the working reference. Where works cross a shared boundary, party wall services sit alongside the daylight piece, and 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 the dense terraced geometry or seasonal access matter to the result for the proposed scheme.
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.
The 2 to 3 week turnaround means the report fits within most planning programmes without slowing submission. Reports follow BRE 209 (2022), and the free initial assessment runs through scope before any fee is set, so an early read on whether a full study is needed costs nothing to obtain at this stage.
