London's planning environment runs across 32 London boroughs and the City of London Corporation, with the Greater London Authority setting strategic context through the London Plan and the Mayor's power to call in referable applications. The actual consent for most developments still sits with the relevant borough. The mix of work runs from the tall residential clusters at Stratford, Canning Town, Vauxhall Nine Elms, and Croydon, through the central conservation-area stock in Westminster, Camden, and Kensington and Chelsea, to the suburban character that defines much of the outer borough belt.
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. Where the scheme involves building over an existing property, airspace development advice sits alongside the daylight piece.
Using the knowledge we have gained throughout our involvement in projects of differing size and complexities, we are able to apply the criteria within the BRE guidelines and produce comprehensive reports to accompany a planning application.
When assessing daylight and sunlight, we work with a professional team to try and achieve the best outcome for a site, whilst respecting the neighbouring properties’ access to daylight and sunlight. We will also provide advice on how the design of potential residential accommodation can ensure access to good levels of daylight and sunlight.
Each London report opens with the proposed scheme drawings, an initial site appraisal, and a 3D model of the development and the affected neighbouring properties. The BRE 209 analysis then runs Vertical Sky Component for daylight, Annual Probable Sunlight Hours for sunlight, and No Sky Line where room geometry matters to the result for the proposed scheme.
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 tall building clusters across central and east London 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.
I have worked with CHP for a number of years, obtaining advice from them with regard to daylight and sunlight. They provide exactly what our clients require and work closely with us to resolve any issues, should they arise.

A formatted report attached to the planning submission gives the borough case officer the technical evidence they need without follow-up requests at validation. Where the figures sit cleanly inside BRE 209 reference values, the planning conversation moves on. Where they sit below, the design rationale, the existing density, and the broader London context explain why the proposal is still acceptable on balance for the case officer to recommend. Referable applications also pass through the Greater London Authority for review against the London Plan.
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.
