Toilet fill valve replacement cost

What costs should I expect and how long will it take? It's just the one that is busted but I'm considering just redoing them all so I don't have to keep calling people out

"I charge £70 including fill valve. More if the cistern is built in as you often have to remove the toilet to get access"

"Yes, somewhere around £75-95 (for parts & labour inclusive) per cistern.. each one approx 1-2 hrs labour (dependant on pipe feeds positioning etc.) If doing more than one or several.. You should really be able to negotiate a further smaller discount. [We would anyhow]!? Hope that helpful. G-TEC Building."

"Hi, can you please confirm if you want the price for supplying and installing, or if you need labour-only for the installation? Once I know this, I can give you the correct quote."
