Firefighters from Mid and West Wales say they're concerned for public safety.
Much of the service is now manned by so-called 'retained' fire crews. These aren't based at a station, but travel there from home or work to respond to an emergency.
Although the Chief Fire Officer says levels of emergency response haven't changed, some firefighters say that though this saves money, it adds time and could put lives at risk.
Firefighter Scott Edwards is one of those who are concerned.
"If you ask a member of the public their perception of the fire service it's when they're in need, the firefighters turn up in a fire truck to a respond to any emergency situation", he says.
"The cuts could put that in jeopardy."
