Street lighting Dimming Trial

Decision Maker: Executive Director Place and Communities

Decision status: Recommendations Approved

Is Key decision?: No

This dimming by 30% can now be considered our baseline. Since 2018, the Council’s inventory of street lighting has increased, not least by adoption of the former SSE network on the Slough Trading Estate. However, no further assessment of its efficiency and cost-effectiveness has been carried out to date.
