I was changing the consumer unit today and look how the previous person has earthed the main water and gas! I will give them 10 out 10 for ingenuity Here's how it looked after i had finished. On a totally different job i was called out to i came across this fitted by a so called electrician. The bottom of the rcd is feeding straight out to the RFC. How he thought that a 63amp RCD on it's own would comply with regulations is beyond me.I had to removed the enclosure and fit a larger one so that i could fit a 32 amp mcb next to the RCD as it needed. The guy even charged £330 just to fit that unit! It saddens me that cowboys like this get away with it and tarnish qualified electricians in the process.
