Hertfordshire’s police and crime commissioner said he is looking at "joined-up" functions between the emergency services when he spoke at a national conference on Wednesday.
David Lloyd addressed the conference, organised by the Chartered Institute of Public Finance and Accountancy (CIPFA), to discuss the integration between blue light services, including how police and fire can work closer together.
Mr Lloyd said that there could be greater cooperation and savings between the emergency services.
He said: "Police and Crime Commissioners across the country, as well as the service chiefs that they work with, will be starting to look at where they sit and where they are heading. Whether you’re looking at service re-engineering or running a more efficient fleet and estate it clearly make business sense to consider the options.
"When it comes to the outcomes we have in mind, I am pretty confident that these are something we can all get behind as well: better service to residents; shorter response times; joined-up and coherent services; reduced cost to the public purse."
He added: "There are also opportunities to have a radical look at how we do business, as well as how we hit our financial targets."
Hertfordshire Constabulary already shares some of its services and back-office functions with neighbouring counties, Bedfordshire and Cambridgeshire.
These departments include finance, fleet, estates and facilities, legal services, human resources, professional standards, training, ICT, firearms licensing, custody and crime recording.
