I have just moved into a new house with a new Mira Play (9.5kw) shower installed. The shower switch outside the bathroom also has a small fuse box below it with a plug-type 13 Amp fuse in it. On the medium heat setting, the shower seems to work fine, but on high heat the fuse always blows and the shower won't work. Should a shower be wired up via a 13 Amp fuse like this? There appears to be a dedicated line from the fuse box for the shower. Are there 30 or 40 Amp fuses I can use without danger or is it more complicated than that?

is it possible to spur off the 45 amp electric cooker supply even thou i have a electric cooker fitted to run a mira play (9.5kw) shower

you can not run a 9.5kw shower on a 13 amp fuse it must be wired straight to the consumer unit on a 45 amp fuse useing 10mm2 cable
