Whoa with the cutting! Undo the nut on the copper pipe and pull the pipe out of the fitting. That will then allow you to undo the brass fitting off the plastic pipe with a pair of pliers, wrench or mole wrench which ever you have that will fit. You will then be able to unscrew the white plastic nuts to remove the float valve. When reassembling the valve and reconnecting the pipe discard that brass fitting and replace it with a 15mm compression to 3/4" BSP bend so if you ever have to replace the float valve again it will be a single nut to unscrew rather than having to undo the whole fitting. If you do not have an isolating valve in the pipe run up to the cistern consider putting one in that way you do not have to turn all the water off to carry out any maintenance on the cistern.

The fitting required will need to be 15mm compression x 1/2" BSP (not
3/4) and it should be a proper bent tap connector with a swivel nut
rather than comp to FI which he appears to have at the moment.

Since he's replacing the valve anyway, cutting through the old one may
be the easiest way of getting it apart - it doesn't need to be done
non-destructively.
