Back to the start

That's what I thought, I spoke to my neighbour about this (fully qualified) and he says competent just means knowledge. Most small jobs on an existing ring can be done by someone knowledgable but not necessarily part p qualified, so if you wanted to add/change a socket you could do as long as it's not in a special location like a kitchen or bathroom. I think the rule of thumb (or common sense) dictates that if you don't know then get someone in who does

My music room does have a dedicated ring main and earthing which I previously used exclusively for the audio system. However it used to niggle me that music seemed almost too perfect, initially very impressive but clinical and somehow lifeless. I persisted with this for several months, convincing myself that this was 'Hi-Fi' sound.  As it was supposed to be an improvement, I really wanted to hear it (placebo effect?) but eventually gave up

Once I reverted to using the normal house circuit, it seemed more organic to my ears and I have stayed that way ever since. Perhaps it's just a fact of getting older and more cynical about snake oil in Hi-Fi. Maybe I am no longer as gullible as I once was. Maybe I am misguided and the 'dryer' sound is what people are supposed to prefer

Transmission via HV cables, substations, shared supplies with other properties, underground LV cables etc over far greater distances than in my house must be having a far greater impact so what real benefit comes from the final few metres? Likewise, fancy expensive power chords, miraculous extension leads etc etc? Some companies make a good living out of this

Please don't let me put you off, I am just relating my own experience
