Interior Daylight Surveys

Quantify daylight levels within proposed buildings. Evidence-based surveys inform design decisions and demonstrate acceptable daylight access for future occupants.

Why Interior Daylight Matters

Daylight access is a key factor in occupant wellbeing, comfort, and satisfaction. Poor daylight levels can negatively affect quality of life and reduce the attractiveness of residential or commercial spaces.

Planning authorities may require interior daylight surveys to ensure new developments achieve acceptable standards, particularly in dense urban environments. Evidence of sufficient daylight provision helps strengthen planning applications and shows commitment to high-quality design.

What Our Interior Daylight Survey Provides

Pager Power undertakes on-site daylight measurements and analysis for completed buildings, using BRE-compliant methodologies to assess internal daylight conditions. Surveys typically include:

  • Measurement of daylight levels in key internal spaces such as living rooms, kitchens, and offices

  • Comparison with BRE standards and relevant planning conditions to confirm compliance

  • Clear illustrations and reporting that make results accessible to both technical and non-technical stakeholders

  • Independent evidence to reassure occupants, support responses to stakeholder concerns, or demonstrate compliance to planning authorities

Where surveys identify shortcomings, our reports provide the context and clarity needed to manage expectations and agree next steps with consultees.
