Daylight and Sunlight Assessment London
Blue Sky Surveyors prepare daylight and sunlight assessments to BRE 209 for planning applications across London, whatever the size of the scheme. Reports are written for the case officer at the council deciding the application. We quote within 24 hours, Monday to Friday.
Daylight and sunlight reports for planning in London
London boroughs ask for an assessment when a scheme is close enough to neighbouring windows to affect their light, stands taller than its surroundings or adds new dwellings. In streets of Victorian and Edwardian terraces that usually means a rear or roof extension facing a narrow garden. Around mansion blocks and mews the question is often a court or light well becoming tighter. On infill and regeneration sites it is a block of flats. In the commercial districts it is a taller building set among older ones.
We model the site and its surroundings in 3D, then test neighbouring windows and gardens and the new rooms against the BRE 209 criteria. The report sets out each result in tables and drawings the case officer can follow. Where a result does not meet the BRE recommendations we explain the context plainly and can talk through changes with your design team before submission.
What you get
- A 3D model of the site built from a survey visit and the surrounding buildings
- Vertical sky component and no sky line results for each neighbouring window tested
- Annual and winter sunlight hours for windows facing within 90 degrees of due south
- A written report with drawings and tables that goes in with the application
We can provide you with a daylight and sunlight report to support your application to your London borough.
Blue Sky Surveyors offer a range of daylight and sunlight services for planning in London. 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 my London borough council require a daylight and sunlight assessment?
Not for every application. my London borough 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 London?
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 London page.
