As i said "I have no idea if this is a silly high figure or not"
I am sure I should know better but I cant think straight. It does not help but some of the appliances we will need have not been purchased and I cant find out their starting current.
I think I have quoted worst case scenario... everything running. 62.5 amps seem low.
21 or 27 amps are just in case but that still leaves 170 to account for.
I read somewhere that RCD's or MCB's can account for start up current so wont trip on start up.

I wish I knew what my main RCD was in my previous place, probably 100.

Anyway, if the network operator can tell me I can go from there.
An added note, apparently the property has 3 phase

Do not worry about the start up current, that will not be the problem - it is the continuous current.

And so far nobody has mentioned "diversity factor", so I will.

For example. just because your cooker hob has 4 rings it does not mean they are all on at the same time, each has a temperature control of some sort etc.

I have a large house, a large well equiped workshop, 2 distribution boards and in all 5 ring mains and 3 main spurs, have not managed to blow the supplier's fuse (yet)

See post 27. That is not a problem. Just look at your continuous load. The inrush current is only milliseconds and if you had a 50 amp fuse it would not blow/trip it.
In fact you are protecting the freezer with a 13 amp fuse. You need to worry about the important things in life.

dont worry I understand start up load and the the mcb's or rcd's are rated so they can deal with start up, I was just mentioning it as i thought it a lot.

You are looking into this subject too much and it's obviously bothering you.
