Underfloor conduit for kitchen island unit?

[FatAlan]

Any recognised / best practice methods / conduit types for routing cables under floor. I’m looking to feed an island kitchen unit so will be looking to supply an induction hob and sockets.
Will be a completely new floor with insulation on top of concrete, underfloor heating pipes, screed with stone tiles on top.

Stick 25mm2 galv conduits in and put a draw wire in, however if the supply to the hob needs to be more than 6mm you will have to think again, PS, make sure the conduit is in one piece without any couplers and make sure any bends flow and are not tight.

As MDJ has suggested, last one I did I ran the 20mm2 conduit from a 100mm galvanised box so I could connect T&E to singles and also earth the containment. The other end went straight to a double socket but again a galv box could be used.

I'd put in some plastic conduit, but not above the ufh.

I did similar when I had to wire up a dentist chair

Presumably singles are easier to route through the conduit than T&E?

Obvious route has to be in the the 50-100mm insulation layer under the heating pipes.

There are, but I also had some 2.5 sat in the back of the van doing nothing so might as well use them.

We just use 40mm twin walled duct.

Is your base floor already laid. Might be a bit of a faff putting any conduit in the insulation.

what about 1/1/4 plumbing pipe.

Fancy name for Kopex I believe......

Depends upon the thickness of insulation but a minimum of 25mm conduit.
