BRE Daylight & Sunlight, Done Right
Independent daylight and sunlight analysis that meets BRE standards — helping you secure planning approval with clarity and confidence.
When a BRE Daylight & Sunlight Assessment is required
You will typically need a BRE Daylight and Sunlight Assessment where:
- A scheme is being prepared for planning submission and daylight or sunlight impacts are a material consideration
- A planning officer has raised concerns relating to daylight, sunlight, or overshadowing
- You are responding to consultation responses or third-party objections
A proposal is being revised or resubmitted following officer feedback or committee deferral
In these situations, clear, planning-focused daylight analysis can be critical to maintaining momentum and avoiding unnecessary redesign.
Understanding daylight is key to planning success:
Daylight and sunlight are material planning considerations affecting both residential amenity and scheme acceptability. Insufficient daylight is a common cause of planning delay, revision, or refusal.
Our BRE-compliant daylight and sunlight assessments provide clear, proportionate evidence to support planning submissions and respond to officer concerns, helping projects progress with confidence.
What is included in a BRE Daylight and Sunlight Assessment
Our daylight and sunlight reports are built around the latest BRE guidance, ensuring that your proposals are supported by robust, defensible evidence. Each assessment is tailored to your site’s geometry, orientation, and surrounding context — balancing environmental performance with design intent.
Our reports typically assess:
- Vertical Sky component
- Daylight Distribution and No Sky line
- Annual Probable Sunlight Hours
- Overshadowing to Gardens and Open Spaces
- Daylight and sunlight access within proposed rooms
Our team applies these metrics with professional judgement — interpreting results within a planning context rather than relying on thresholds alone. The outcome is a clear, balanced report that demonstrates compliance while strengthening your planning submission.
