so is it acceptable for me to have an isolator,no rcd and just mcb's?

Since you are not on a TT supply, then you don't require RCD protection
for ALL circuits. However, you should have RCD protection (30mA trip) on
any socket circuits that might conceivably supply power to portable
appliances that could be used outdoors.

So in answer to your question, the strict answer is likely to be "no".
Whether you need RCD protection for the particular circuit in question
however will depend on the layout of your house etc.

As it is not a TT supply then what about no RCD on the CU and have a couple
of these http://tinyurl.com/47q2b
