What we do

There are many forms of light pollution and these are generically referred to as ‘obtrusive light’, which if not properly controlled can have physiological and ecological impacts. Since 2006, artificial light has been included on the list of possible Statutory Nuisances in England, Wales and Scotland and is also now referenced in both National and Local planning policy. The National Planning Policy Framework (NPPF) stipulates that: “By encouraging good design, planning policies and decisions should limit the impact of light pollution from artificial light on local amenity…” Paragraph 7.19 of the London Plan states: “The lighting of the public realm also needs careful consideration to ensure places and spaces are appropriately lit, and there is an appropriate balance between issues of safety and security and reducing light pollution.” For new developments there is now an opportunity for LPAs to impose planning conditions related to external lighting, including curfew hours. In recognition of the growing need to assess and mitigate environmental impacts, we have included Light Pollution/Light Impact Assessments as one of the services we offer. Herrington Consulting has long track record of analysing environmental impacts across a wide range of sectors. Therefore, drawing on our extensive experience in using detailed computational modelling techniques, we are able to analyse the impact of new or existing development on its surrounding environment. .



Is a Light Pollution Assessment Required?

The following questions have been taken from the Gov.uk document ‘Light Pollution’ published on the 6th March 2014 by the Ministry of Housing, Communities & Local Government and will help to identify when the possibility of light pollution might arise: Does a new development proposal, or a major change to an existing one, materially alter light levels outside the development and/or have the potential to adversely affect the use or enjoyment of nearby buildings or open spaces?

  • Does an existing lighting installation make the proposed location for a development unsuitable? For example, this might be because the artificial light has a significant effect on the locality, or users of the proposed development (eg a hospital) may be particularly sensitive to light intrusion from the existing light source.;
  • Does a proposal have a significant impact on a protected site or species eg located on, or adjacent to, a designated European site or where there are designated European protected species that may be affected? ;
  • Is the development in or near a protected area of dark sky or an intrinsically dark landscape where it may be desirable to minimise new light sources?;
  • Is the development in or near a protected area of dark sky or an intrinsically dark landscape where it may be desirable to minimise new light sources?"
  • Are forms of artificial light with a potentially high impact on wildlife (eg white or ultraviolet light) being proposed close to sensitive wildlife receptors or areas, including where the light shines on water?"
  • Does the proposed development include smooth, reflective building materials, including large horizontal expanses of glass, particularly near water bodies (because it may change natural light, creating polarised light pollution that can affect wildlife behaviour)?"

If the answer to any of the above questions is ‘yes’, local planning authorities and applicants should think about:

  • where the light shines;
  • when the light shines;
  • how much light shines; and;
  • possible ecological impact."
