The cut affects six school sites across the borough including Orchard Way Primary in Shirley.
The decision was revealed through a Freedom of Information request by InsideCroydon.
It will see the crossing services during school drop-off and pick-up hours stopped at the end of the year.
A spokesperson for Croydon Council said:
“Croydon Council will close its remaining non-statutory School Crossing Patrol service at the end of this school year, affecting six sites.
“This decision follows a 2022 service review and was discussed at the Council’s Scrutiny and Overview Committee in December 2022, before being confirmed as part of the Medium-Term Financial Strategy agreed by Cabinet in October 2024.
“Most patrols were phased out many years ago and risk assessments have been completed for the six remaining sites, with one now earmarked for a permanent crossing and three located on Healthy School Streets.
“Schools were notified in March 2025 and our Road Safety Officer continues to work with them on initiatives such as Junior Roadwatch. Whilst this is a non-statutory service, road safety remains a priority for the Council.”
