the shower cable is 4mm very old stranded cable and the earth wire well its connected some where certainly not to the gas or water bit unsure where its connected , and you are right it has had some work done to it central heating installed and the shower put in less than 6 months ago , because the installation was in such a poor condition i didnt delve into it to much but what i do know is the is no circuit in the board for the shower and it appears to be an old immersion heater supply with a 20 amp pull switch ,
UPDATE
The house is to be rewired starting on tueday next week quote accepted , its not an easy one occupied house so need to leave some electricity , but when i walk in on tuesday the supply will be cut and new supplies installed , if i come accross any more dodgy pics i will post on here once i start
