Power flush vs single radiator flush

What type of prices am I expected to expect and also separately to fit a magnetic filter to reduce sludge build up. Sadly one of my radiators is cold at the bottom and warm ish at the top, bleeding releases no air.  Radiators and boiler are all 5 years old. 

I guess if doing one radiator I may need them all done? Also when powerflushing, where does the sludge go?

Full reverse flush is normally put straight down an external manhole from the machine. I'd do them all at the same time if there is sludge in the system

Thanks, I suppose makes sense to be do it all, guess it would be false economy to just do one, with a potential for needing another radiator done in a few years time.

The worse thing is I use water softener as well which in theory should reduce some of the sludge.
