Electrics under the bath

[CatHedger]

Hi, I’ve just taken off the side of the bath with the aim of fitting an overhead shower to the bath, and have found an electrical unit under the bath, which appears to be for the central heating system. It’s fixed to the floor, so it’s not raised, and the fact that a small ingress of water has made the floor board damp near the 230 volt unit has made me even more concerned as to whether this is safe and meets British standards. My dad told me not to worry about the bolts as amps will kill me, but I’m still concerned as can’t see any info on this under the bath. House is 5 years old. Is it ok? Looks like it’s in zone 0 as I’ve had to take side of bath off with a screwdriver, but still, there’s a leak on be copper pipes too. Doesn’t feel right. Any advice is greatly appreciated.View attachment 43425View attachment 43425View attachment 43426View attachment 43425View attachment 43426
