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.
Overshadowing analysis on ground-level amenity and public realm tests the 21 March sun position recommended in the guidance. Sunpath studies cover seasonal access where these add useful evidence, particularly on the Thames-side tower proposals where cumulative shadow effects matter to the planning conversation. Trees within the impact zone are factored in where they materially affect the outcome.
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 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 whether a full study is needed at this stage of the project.
