In November 2025, Network Rail published updated guidance on assessing glint and glare impacts towards railway receptors, which includes scope for assessing glare towards both rail drivers and signalling assets. [...]

Solar farms can cause reflections throughout the day when sunlight hits the surface of photovoltaic (PV) panels. Depending on the orientation of the panels, the Sun and nearby receptors, these [...]

Aviation glint and glare assessments for solar PV almost always become more complex than initially anticipated, and possibly counterintuitively, they typically get more complicated when assessing smaller general aviation aerodromes, [...]

When undertaking glint and glare assessments, it is often necessary to predict not only whether solar glare is geometrically possible, but also the glare intensity: how intense any instance of [...]

In March 2025, glare from a nearby solar farm temporarily closed one runway at Amsterdam Schiphol Airport, causing significant disruption as incoming flights had to be diverted to alternative runways. [...]

For any project involving solar panels, or any other potentially reflective surfaces such as glass, or metal façades, a glint and glare assessment may be requested by the local planning [...]

Permitted development rights Permitted development rights in the UK allow certain things to be built or changed without the need for a planning application. Essentially, the idea is that certain [...]

In August 2025, the British Horse Society (BHS) updated their guidance on solar farms near routes used by equestrians [1]. This guidance covers a variety of topics, including noise, drainage, [...]

How early in a project should I commission a glint and glare assessment? Like most questions around planning applications, there is no one size fits all answer to this question, [...]

Depending on the surface conditions reflections of light can be specular or diffuse. A specular reflection has a reflection characteristic similar to that of a mirror, whereas a diffuse reflection [...]
