The Met’s force of 1,000 PSCOs were recently saved after ministers dropped plans for controversial cuts to the police budget.
With London’s other blue light services facing budget and operational challenges, Assembly Member Tony Arbour says greater use could be made of the PCSOs to ensure Londoners get “best value for money”.
In a report published on Friday, Mr Arbour suggests the officers could provide fire prevention advice to older and vulnerable householders and be trained in lifesaving skills such as the use of defibrillators.
He also suggests PCSOs could assist Local Authority Enforcement Officers and Trading Standards in tackling flyposting and littering.
Mr Arbour said: “There’s nothing worse than wasted potential, and PCSOs can do more for London.
“Around the country, PCSO’s are already training to provide fire safety advice and emergency medical care – London should be doing the same.
“By including PCSOs in training already taking place across London, we could easily create Tri-Service Officers, giving London additional fire safety and lifesaving support.
“This isn’t about replacing roles, this is about strengthening local services.
“The future of our emergency services is co-responding, and this is a real way to implement that today.”
