What is a planning-compliant lighting design?

A planning-compliant lighting design is a professionally prepared lighting scheme that demonstrates how external lighting will meet the requirements of a planning application while minimising environmental impact.

Many developments now require careful consideration of light spill, glare, upward light, biodiversity and the protection of wildlife corridors. Our lighting designs use recognised guidance, technical calculations and best practice principles to create solutions that provide the required illumination while reducing unnecessary impact on the surrounding environment.

​

Do I need a lighting report for planning permission?

A lighting report may be required where a development includes external lighting or where lighting could affect nearby properties, highways, protected habitats or wildlife.

Typical projects that may require a lighting assessment include:

• Barn conversions and rural developments

• New residential developments

• Commercial buildings

• Sports facilities

• Padel and tennis courts

• Caravan and holiday parks

• Developments close to woodland, watercourses or ecological habitats

• Projects involving bats, birds or other protected species

A lighting assessment can help demonstrate to planning authorities that the proposed lighting has been carefully considered and that measures have been included to reduce environmental impact.

​

What is a DIALux lighting report?

DIALux is professional lighting design software used to model and calculate lighting performance.

Using DIALux, we can create a digital representation of a site and assess:

• Horizontal illumination levels

• Vertical illuminance

• Light spill onto neighbouring areas

• Lighting levels around boundaries and habitats

• Glare and obtrusive light

• Luminaire performance and positioning

The results can be presented within a technical lighting report to support planning submissions and demonstrate compliance with project requirements.

​

How do you reduce light pollution?

Good lighting design is about providing the right amount of light, in the right place, at the right time.

We reduce light pollution by considering:

• Selecting efficient, well-controlled LED luminaires

• Using warm white light sources where appropriate

• Avoiding unnecessary upward light

• Using accurate aiming and positioning of luminaires

• Controlling operating hours through timers, sensors or lighting controls

• Reducing light spill into neighbouring properties and sensitive areas

• Creating lighting zones based on actual requirements

The aim is to provide safe and functional lighting while protecting the character of the surrounding environment.

​

What lighting is suitable near bat habitats?

Lighting near bat habitats requires careful consideration because artificial light can affect bat commuting routes, feeding areas and roost locations.

Sensitive lighting approaches may include:

• Warm white LED lighting (typically 2700K or below where appropriate)

• Low intensity illumination

• Directional downward lighting

• Avoiding illumination of trees, hedgerows and bat corridors

• Maintaining dark areas between habitat features

• Using controls to reduce lighting duration and unnecessary operation

Each project should be assessed individually, taking into account the ecology survey information, site layout and planning requirements.

​

What lighting levels are acceptable near wildlife areas?

The appropriate lighting level depends on the sensitivity of the location and the requirements of the project.

For ecologically sensitive areas, maintaining very low levels of illumination may be necessary to protect wildlife corridors and habitats. Lighting designs are developed around the specific ecological constraints of the site and may include calculated light spill limits, dark corridors and mitigation measures.

​

How long does a lighting assessment take?

The timescale depends on the complexity of the project, the size of the site and the information available.

A typical external lighting assessment may involve:

1. Review of drawings, planning conditions and ecological information

2. Assessment of lighting requirements

3. Development of a lighting concept

4. DIALux modelling and calculations

5. Preparation of the lighting report

6. Review and amendments if required

Most smaller projects can usually be completed within approximately 2–3 weeks once all relevant information is available.

​

Can you help with planning condition discharge?

Yes. We provide lighting assessments and reports to support the discharge of planning conditions relating to external lighting.

We can review planning requirements, develop an appropriate lighting strategy and provide supporting documentation demonstrating how the proposed scheme addresses issues such as light spill, biodiversity and environmental impact.

​

Do you work with ecologists, architects and planning consultants?

Yes. We regularly collaborate with architects, developers, planning consultants, ecological consultants and contractors to integrate lighting solutions into wider project requirements.

Our role is to provide specialist lighting expertise that supports the overall design process and helps achieve planning approval while delivering practical lighting solutions.

​

Can you provide lighting de

signs for rural and heritage buildings?

Yes. We have experience working on sensitive locations including rural properties, historic buildings, churches and environmentally sensitive sites.

These projects require a balanced approach that enhances safety and usability while respecting the character of the building, landscape and surrounding ecology.
