Daylight and Sunlight Surveyor in Merton
BRE 209 Assessments in Merton
Merton combines the new tall residential clusters at Colliers Wood and South Wimbledon with the substantial Mitcham and Morden regeneration coming forward across the south of the borough, the Wimbledon Village and Merton Park conservation-area stock, and the suburban residential character running through Raynes Park and Wimbledon Park. The London Borough of Merton reviews a steady caseload of mid-rise residential proposals, replacement housing, conservation-area infill, and rear and side extensions across the wider borough.
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 for larger developments that could affect a neighbour's legal entitlement to light, rights of light assessments sit alongside the planning piece, particularly on the Colliers Wood tower schemes.
Daylight + Sunlight
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.

How do we approach daylight and sunlight assessments in Merton?
Each Merton 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 Colliers Wood tower cluster and the Mitcham regeneration phases 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.

How does a daylight and sunlight report support a Merton planning submission?
A formatted report attached to the planning submission gives the London Borough of Merton 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 at Colliers Wood, and the masterplan context across the Mitcham and Morden regeneration zones explain why the proposal is still acceptable on balance for the case officer to recommend.
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.
