What would be a rough guess for the price to replace my old combi with
another one in same position? Just the fitting, as I am looking to get
a unit myself after looking around a bit more.

I currently have an 80k btu unit and would want to move up to a more
powerful one over 100k btu.
I am also considering getting one with instant hot water.

Any advice gratefully accepted.

I am in East Kent.
