Loss of Light Planning Objections

Professional Assessment and Objections for Daylight & Overshadowing Impacts

Loss of light is one of the most common and impactful reasons for objecting to a planning application. If a neighbouring development threatens to reduce the natural light entering your home, garden or business premises, Cedar Planning can prepare a strong, policy-led objection that clearly demonstrates planning harm.

We support homeowners, neighbours, community groups and businesses in preparing effective objections grounded in daylight/sunlight guidance, planning policy and local design standards.

Why Loss of Light Matters in Planning Decisions

Local planning authorities must consider whether proposed development would cause:

• Unacceptable loss of daylight

• Significant overshadowing of rooms or gardens

• Reduced sunlight to key living spaces

• Overbearing visual impact caused by increased height or massing

Many councils rely on:

• BRE Guidelines: “Site Layout Planning for Daylight and Sunlight”

• Local design guides

• Neighbouring amenity policies

We ensure your objection demonstrates harm using the criteria planning officers must consider.

Common Causes of Loss of Light

We regularly prepare objections relating to:

• Two-storey side or rear extensions

• Loft conversions with large dormers

• Deep rear projections

• New dwellings built close to boundaries

• Oversized garden outbuildings

• Blocked south-facing windows

• Multi-storey developments overshadowing gardens

• Infill developments in tight urban plots

Even small extensions can dramatically reduce daylight depending on orientation and proximity.

If your concerns include other issues such as overlooking, overdevelopment, or Green Belt impacts, see our full Planning Objections Guide.
