A friend of mine wants to bring the electrics on a property of his up to
scratch, and also get some storage heaters fitted, and got the local
supplier in to give him a quote - as he lives some miles away I agreed to
have the key and let them in. I was surprised by one or two things that they
said about his electrics, and by the quote, so I'd be grateful for the views
of more knowledgeable people here.
The property has just had a new kitchen fitted by a specialist company and
they, as would be expected, supplementary bonded the incoming water pipes
and also the sink top and draining board - using 6mm cable to do it. The
suppliers electrician said that they shouldn't have bonded the draining
board, which seemed pretty strange to me. Also, as I noticed that the
property is PME protected, I thought that all the bonding should be 10mm -
he said that 6mm was ok.
The existing consumer unit is the wired fuse type which my friend wants
replaced so that the property benefits from RCD protection - as he wants to
let the place. I was surprised when the Board's electrician said that,
although it was a good idea to replace the CU, it wasn't absolutely
As for the quote: for 3 storage heaters - 12, 18 and 24 - replacing the
consumer unit and fitting a second (3 ways) for the Economy 7 supply and
tidying up the bonding in the bathroom and kitchen, £2,617 - which I thought
was very steep.
