514.1.1 Except where there is no possibility of confusion, a label or other suitable means of identification shall be provided to indicate the purpose of each item of switchgear and controlgear. Where the operator cannot observe the operation of switchgear and controlgear and where this might lead to danger, a suitable indicator shall be fixed in a position visible to the operator.
Placing an isolator out of sight may be considered to not comply with the above. Some people seem to have some funny ideas and don't read the regulations but jump to conclusions and just the other week I had to get out the book to show an inspector when there was a sub main supplying the kitchen there is no need for an isolator as well as the RCBO. So unless you want to have a confrontation with building inspector I would ask him what he will accept.
Making and submitting a detailed plan is always good practice. If you can say with hand on heart "I told you my intentions on <date> and you had no objections what has changed?" Then often they will back down. But where you submit the plan in wide general terms then of course they can and will object when they think it does not comply. Even if it does.
Also I have been to a number of jobs where the LABC did not realise they were to be passing the electrics. So do make it plain what you are expecting from LABC. The rules have changed slightly and now they can pass on costs of employing a third party to test your installation. And what they will accept as to showing you are competent also seems strange. They would not accept my son who had his C&G 2391 but allowed me to sign as I had a degree in Electrical and Electronic engineering. Yet the latter teaches nothing about inspection and testing. I also had a C&G 2391 but they didn't know that.
The hob normally has an isolator and a connection unit. The connection unit very likely not visible once everything is installed.
