16A will be fine, but 20A would be more normal. You don't have to run the sockets in a ring. You can branch off to your heart's content. Don't worry about not having 32A available, I don't think you need the ability to run 7kW of appliances up there!

right .loft is going to be a computer room and studio for myself it has 4 double sockets cable goeas into first then daisy chains to the last is this also the correct way or not
I would not see a problem using a 16amp MCB on such a load, but 20A is usually used. What sort of electricians "told you to buy" such parts as MCBs? Supplying these should be part of their service. You would not take a car in for repair and be told which parts to bring.

Unless the guy wanted to keep his turnover down? But I would have though that 1 MCB would not have made a lot of difference.
You can wire it in any configuration that pleases you. You can daisy chain each in turn, run as a ring, or branch off in a tree.
Unless you are planning to have a 3kW fan heater up there, I wouldn't bother changing to a 20A MCB. You'd probably actually get the 3kW fan heater and computer simultaneous on 16A, anyway.
