Taking it that the gap between the hot and cold entry pipes are the same on the new valve as the old one, is it simply a task to isolate and undo the supply pipes and fit the new valve or am I still going to have to make holes in the walls to gain access to the pipework?

hi, isolate both supplies, saying that connection center to center is the same,disconnect old valve,if theres enough play in the pipework cut the copper, remove nut and ring,fit new valve, if pipework is solid try cutting the O ring off only, be carefull not to cut into copper,remove o ring and nut, replace valve,turn water back on check connections, then operate shower valve ( remove shower head to flush system to eliminate any debris)
