Shadow Flicker Impact Assessment
Assess and quantify potential shadow flicker from wind turbines. Independent evidence informs planning, reassures consultees, and identifies mitigation options where impacts may arise.
Why Shadow Flicker Assessment Matters
Shadow flicker occurs when the rotating blades of a wind turbine periodically block the sun, creating a flickering effect that can impact nearby homes and workplaces.
Unmitigated shadow flicker can lead to planning objections, project delays, and reputational risk. With over 2,000 wind assessments completed worldwide, Pager Power helps developers avoid these issues by delivering clear evidence that withstands scrutiny from planning authorities.
What Our Assessment Provides
Our shadow flicker assessments determine whether a development could cause significant impacts on surrounding dwellings by modelling expected shadow patterns throughout the year.
We identify which properties may be affected, estimate the duration of any flicker events, and compare results against relevant national or international planning guidelines.
Where issues are found, we recommend mitigation strategies such as layout adjustments, operational controls, or turbine shutdown schedules to remove or reduce impacts. Reports are clearly presented, with visuals that make findings easy to understand for planning officers, consultees, and the public.
Pager Power’s industry-standard modelling and almost two decades of wind project experience ensure accurate assessments that give stakeholders confidence and help keep projects on track.

Pager Power has helped us obtain planning permission across the UK
We first appointed Pager Power in 2004 to assess a number of wind farms in North East England resulting in objections being withdrawn by Newcastle Airport. The company has successfully helped us resolve NATS, Royal Airforce, telecommunications and minor airfield issues. Pager Power provides advice and technical analysis, are easy to talk to and deliver reports on time. Pager Power has helped us obtain planning permission across the UK including a range of onshore wind farms in North East England and Central Scotland.
