This was a pre PIR visit, the manager said would I put back all the bonding as it had been cut off when the place was refurbed, I said it was unlikely to be nessesary but I would test it none the less, a quick look round showed every thing including the sink top had been at some point been bonded, but then again it was ex council property at some time in the past and I think the manager has been there since, My initial thought was if it is bolted to the wall then it,s extraneous and will be at 0 potential however the PIR will decide.
