Preparing ground for a shed

[Soong]

I removed my old shed which was laid on this concrete. I bought a wooden base for the new shed which is coming in a few days.

This is the base: https://www.sheds.co.uk/adley-wooden-shed-base.html

Is it safe to assume I can just lay that base over the concrete and that's it?

The concrete isn't completely level but I assume the wooden base over it means it doesn't have to be?

Looking at the base you have purchased from https://www.sheds.co.uk/ it does not look as if the feet on the shed base are adjustable, picture of feet is poor but it does say "Allows you to make a flat base on uneven ground and is a reliable alternative to concrete."

Something like this I would use https://www.shedbase.com/quickjackpro/

Well the base would be flat even on a hill, but it might not be level. Guess you'll have to wait and see when it arrives.

Cheers those look very handy. I'll get some if it's not level.

Just been to look at the slabs and it seems like the central ones may cause it to not be level.

If I remove those and just have the outside ones that should still be fine if it means it's level? As the struts of the wooden base will be doing all of the supporting?
