I was trying to find concrete/screed floorboards that can be used as the structural floorboard and at the same have the grooves for the underfloor heating pipes.

The idea of using a concrete/screed floorboard is to have better thermal conductivity and less height instead of using floorboards and then a underfloor heating panel on top.

There are regular chipboards for underfloor heating that I'm also researching about, but considering the pricing, it may be better to just use regular chipboard and then additional underfloor heating panels on top.

If anyone has some advice on best options for underfloor heating in a loft, that would be great. I'm planning to use the same procedure on the 1st floor of the house later once we work our way down.

This is all very unclear

What about the first 2 options here

I used the *profloor* option for our second floor heating topped with
12mm ply. (pipe runs carefully marked!)

Curious about the concept of a heated loft floor. Grow-lights ?

I assume it's a loft conversion, and because of the pitched roof there
aren't vertical walls on which to mount radiators. So UFH is another
option.

As per the recent 'noises in the loft conversion' thread, pay close
attention to the correct way to mount any panels to allow for expansion
movement.

A Grand Designs program of many years ago featured a modern
'box like' house in London that was fitted with hot wall
panels, which I think were pregrooved flooring panels with
inset 10mm polypex piping.

The distribution manifolds come with auto air release provision. Unless
you have high flow rates, I see any vertical system being vulnerable to
air collection.
