I assume your gonna be fitting a new consumer unit too? The job's notifiable to the LABC under Part P, and requires the relevant BS7671 testing & certification (You know the ones: R1+R2, Zs, IR, RCD tripping etc)
Fluff - if you use that calculator select 2-core SWA even if you're using 3-core, or it'll do 3-phase calculations, and select PVC even if you're using XLPE or it'll run the conductors up to 90°...
Thanks guys
I am rotovating the garden soon so would like to lay the cable now I know it is def 4mm required.
Where can I get hold of the warning tape to lay above the cable? I take it any decent elec maerchant would stock it.

A common error in taking the simplistic view of over-engineering a solution so as to avoid the uncertainties of correct design, is that it doesn't take into account other factors.
If you decided to install so much equipment in your shed so as to max. out 10mm armoured, one would have to question the loading in the rest of the property served by a (max.) 100A main service.
This is not to say that 10mm wouldn't be appropriate for your installation given other considering factors, but going overboard is a simple waste of money are resources.
If 4mm may not give you sufficient for future use, 6mm will give you all that you should ever require as it could carry about 50% of the total property loading. Can you envisage a time when 50% or more of your total electrical loading will be in your garden shed?
