Daylight and sunlight reports for planning in Wimbledon
Merton Council looks for a daylight and sunlight assessment when an application puts new bulk close to neighbouring windows or creates new homes whose own light needs checking. In Wimbledon that might be a rear and loft extension to an Edwardian terrace, a replacement house in the Village with neighbours on both sides or a block of flats beside the station. In Raynes Park and Colliers Wood the usual application is an infill house or a conversion on a tight plot.
We build a 3D model from our own survey and the application drawings, run the vertical sky component, no sky line and sunlight tests on the neighbouring windows and set the results out in a report ready to go in with the application. A result that does not meet the BRE recommendations is stated plainly with the reasons behind it. If the architect can still change the scheme we can test alternatives first.
What you get
- A 3D model built from our own site survey and the application drawings
- Vertical sky component and no sky line results for each neighbouring window at risk
- Annual and winter sunlight hours for south-facing windows plus garden overshadowing on 21 March
- Internal daylight and sunlight results for new flats and houses where the planning officer asks for them
We can provide you with a daylight and sunlight report to support your application to Merton Council.
Blue Sky Surveyors offer a range of daylight and sunlight services for planning in Wimbledon. Below, you will find details on the services we offer.
If a planning authority have requested that you provide a daylight & sunlight assessment detailing the likely impact on neighbours, then we can help. We will build a 3-D CAD model of your proposal and run all of the required assessments as outlined in the BRE Guidelines: site layout planning for daylight and sunlight: a guide to good practice (BR209).
We will then outline the results of the study in a formal report which can be submitted in support of your planning application.
If you wish, or need, to minimise the impacts to the neighbouring properties (to improve the chances of the planning authority accepting the application), we can work with your architect to amend the design in order to adhere to the BRE guidelines.

Daylight & Sunlight within the development
Sometimes local planning authorities will require you to show that the proposed units in your development will meet the minimum daylight & sunlight requirements as outlined in the BRE guidelines. We can model your proposal and run an internal daylight & sunlight assessment which will show what light levels will be enjoyed within the proposed units. We will then outline the results of this assessment in a formal report which can be submitted in support of your planning application.

A maximum envelope study will help your architect early on in the design process by providing a maximum massing parameter in which the BRE recommended guidelines for daylight & sunlight will be met. We can provide you with a 3-D maximum massing model which can be easily utilised by your architect.

Frequently Asked Questions
What is a daylight and sunlight assessment?
An assessment of the effect a proposed building will have on the daylight and sunlight received by neighbouring properties, or of the daylight and sunlight that new homes will receive, carried out against the BRE guide Site Layout Planning for Daylight and Sunlight (BR 209, 2022 edition). It is a planning matter and is separate from a neighbour’s right to light.
Which tests are carried out?
For neighbouring properties we test daylight using the vertical sky component (VSC) and the no sky line (daylight distribution), and sunlight using annual and winter probable sunlight hours (APSH) for windows facing within 90 degrees of due south. Where gardens and amenity spaces are affected we test overshadowing on 21 March. For new homes we assess the daylight and sunlight within the proposed rooms against the targets in BR 209.
Does Merton Council require a daylight and sunlight assessment?
Not for every application. Merton Council will normally ask for one where a proposal sits close to neighbouring windows, is taller than the buildings around it or creates new homes, and the request often arrives from the case officer during validation or after neighbours have objected. If you have been asked for a report, send us the drawings and the council’s comments and we will quote within 24 hours.
What do you need from me?
The site address, the proposed drawings (plans, elevations and sections) and a copy of the council’s request if you have one. We build the 3D model from the drawings and any survey information needed, run the tests and write the report. Send the drawings over and we will quote within 24 hours, Monday to Friday.
What happens if a result does not meet the BRE recommendations?
The BRE figures are guidance rather than fixed limits and the planning authority will weigh them against the wider merits of the scheme. Where a result does not meet the recommendations we explain why, set it in context and, where it helps, work with your architect on changes that bring the scheme back within the guidance before the application goes in.
Will the report deal with my neighbour’s right to light in Wimbledon?
No. A right to light is a separate legal matter and a scheme can satisfy the planning tests and still infringe a neighbour’s right to light. We assess that separately; see our rights of light surveyors Wimbledon page.
