It's not a set up I'm familiar with but I would suggest laying a 6mm insulation board then tiling onto that to get your 10mm rather than trying to get 10mm with adhesive which you will not be able to do successfully.

The tiler who gave me a quote advised that he would use "Norcros Thick Bed Stone and Porcelain adhesive".

Apparently this adhesive can be troweled on up to 25mm thick?

It certainly can but as local said it would be easier and quicker to ensure solid bed using a 6mm board first.

I don't know Norcros adhesives, and I'm never likely to, but in my experience the maximum bed depth of an adhesive will relate to small isolated areas and not the whole install.
It could well be cheaper to use a board or latex to make up the deficit.
I'd probably go with latex, to obtain a perfectly level substrate.

with slc and adhesive being about the same price why wouldn't you!
yes, you may have to pay an extra days labour to lay it but your save that on fixing the stone.

Completely agree with @3_fall plus with heavy stone, bulking out 10mm of addy you would undoubtedly result in some slumping issues as it dries

I would go for the insulation board personally, flatness will be no different if laid right.

Latex or board is much of a muchness, latex would probably be a bit cheaper not much in tho, but just certainly not bulking the whole job up with 10mm of addy

>22 mm limestone + 6mm insulation board = 2mm for adhesive !!! Need to be on site to know exact sub base preparation .
See the work potential Tilers have done and check them out, 3k + is a decent wad to throw away.

Cost of laying will also to an extent vary with the size and type of limestone flags. Larger pieces are a two man job to lift and position them. Some limestone I have laid has been flat finish so that the finished floor is flat like a supermarket floor. Other limestone has been more rustic (riven surface edges not flush with each other etc.) and requires more adjustments in the thickness of the adhesive.

Gentlemen,

Thanks again for your advice.

The Limestone size is 600mm x 900mm tumbled edges and tumbled surface, so definitely not smooth. I've uploaded a photo of the flagstones. The photo shows exactly how I would like the finished look.

I phoned two tilers today and am beginning to get the feeling that not too many tilers have experience of laying 20-22mm thick Limestone flagstones?
