BRE‑Compliant Reports for Extensions, New Builds & Neighbour Objections

When your planning officer requests a Daylight & Sunlight Assessment, you need a report that is accurate, defensible, and fully compliant with BRE 209. We provide fast, specialist daylight & sunlight analysis for extensions, lofts, outbuildings, new builds, and multi‑unit developments — including VSC, APSH, Overshadowing, 25°/45° tests, and full 3D modelling.

⭐ Why You Need a Daylight & Sunlight Report

Local authorities rely on BRE guidelines to assess whether your proposal:

Causes loss of light to neighbouring windows
Creates overshadowing to gardens or amenity space
Fails Vertical Sky Component (VSC)
Fails Annual Probable Sunlight Hours (APSH)
Breaches the 25° or 45° rule
Impacts daylight levels within your own development

A compliant report can be the difference between approval and refusal.
