No.
An isolator won't provide overload or short circuit protection for the cable.
A fusebox located in a commercial kitchen is a poor choice, it should be located in a separate room.

Dunno.
Will 100A TP be enough for a commercial kitchen? Will 25.0mm² be big enough to provide a 100A supply in that environment, taking into account the ambient temperature derating factor?
There is no way anyone on here can answer your question without a lot more info, which you dont seem to have.

How have you decided on the size of the cable?
35M is a long way, why is it so far from the supply?
It might be better to get a new supply put in locally to where it is needed.
Are you a builder or an electrician?

Am an electrican, gonna put rcd board in kitchen, the kitchen is really small so wont be loads of cookers more mircrowaves, mixers, kettles ect so just thought that it wouldnt pull more than 100amp so picked 25mm because it can carry appox 150amp
No it can't. Unless by 'appox' you mean 'significantly less than'.
