Drivers who leave their vehicle’s engine running while parked face a £20 fine after Lambeth Council introduced the penalty to improve air quality.

Drivers who allow their vehicle engines to run “unnecessarily” when parked in the London borough will be asked to turn off their engines, and if they fail to cooperate, will be issued with the fine from Monday (May 18).

The move builds on previous anti-idling events in the borough to raise awareness and educate drivers on the effects of idling, it said.

Councillor Claire Holland, Lambeth’s deputy leader  and cabinet member for sustainable transport, environment and clean air, said: “Cleaning up toxic air is an absolute priority for this council.

“Poor air quality is a huge health risk to our residents, and engine idling is a major contributor. We are determined to tackle the issue and are confident these new measures will help encourage people to change their behaviour so that everyone in Lambeth – particularly young children due to the effects on their development – is able to breathe clean air.”

In Lambeth, Waterloo, the Southbank, central Brixton, Clapham and the Vauxhall Gyratory have been identified as idling hotspots.

Outside schools, hospitals, taxi ranks and coach bays have also been flagged as key locations for drivers committing idling offences.

Between February 2018 and September 2019 wardens in Lambeth told 2,044 drivers to switch off their engine while stationary, of which 2,017 drivers complied with their advice and 27 people did not.
