Our team prepares these reports under RICS regulation from our London office at Boundary Row, SE1, with BRE 209 (2022) as the working reference. For larger developments that could affect a neighbour's legal entitlement to light, rights of light assessments sit alongside the planning piece, and the practice has been delivering daylight and sunlight reports since 2004.
Overshadowing analysis on ground-level amenity tests the 21 March sun position recommended in the guidance. Sunpath studies cover seasonal access where these add useful evidence, particularly on the conservation-area infill where existing density and orientation drive much of the result. Trees within the impact zone are factored in where they materially affect the outcome of the assessment.
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.
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.
