Underfloor conduit for kitchen island unit?

Been there, done that (at customers request).

Actually, thinking about it a bit more you could create some sort of framework / H frame to hand pots and pans on.

Get your tin hat on sharpish mate , you'll be advised that conduit isn't designed to support additional weight of any sort apart from a very small spider- most likely with reg numbers quoted, and it would most certainly need a 50mm2 main bond back to the DNO transformer.
