Having read many threads about bonding I am still confused.
The question is, when did all this stuff come in?
The reason I ask is because I now have my 4th property.
House #1, built 1947 - rubber wires in steel conduit, steel bath, no bonding to gas or water, no equipotentials. I rewired it in 1980 and the technician from Southern Electricity connected my CU without comment.
House #2, built 1956 - rubber T&E, steel bath, no bonding to gas or water. CH installed between build & 1984, no equi's. No other significant modifications.
House #3, built 1973 - PVC, bonding to secondary hot & cold only. Gas pipe & meter was repositioned and changed from steel to copper during previous ownership (before 1994) but not bonded. I have now bonded the gas pipe to CU and, after fitting a shower pump (with RCD), have also equi'd everything in the airing cupboard. Water supply pipe still not bonded (needs carpets & flooring raised to route a cable).
Flat #4, built 1982, 1st floor. Gas meter on ground floor bonded to electricity meter, water pipe not bonded. Original CH. Electric shower fitted with separate CU between build & before 2005. No equi's except H to C under kitchen sink.
In other words, all this stuff about bonding is comparatively recent. So what's the history? Even though the #4 met the regs at the time, should the supply pipe be bonded and the airing cupboard be equi'd now?
