I've had my underfloor heating installed but not wired in yet. I plan
to wire it in where I have removed a double socket, so on the ring
main. Do I just wire in a FCU to the old socket cables and then the
thermostat from that?

Alarm bells loudly ring. What's the scope of the underfloor heating
installation and what sort of load are we talking about?

I read in some posts that permanently fixed heating devices shouldn't
be wired directly to the ring main and if this is true [...]

Quite right. Any comprehensive space heating installation needs its own
dedicated circuit or circuits from the consumer unit or distribution
board. Unless this is something very small and localised it's not at
all appropriate to feed it from an existing ring circuit.

Underfloor heating comes under the 'special installation' provisions of
Part P and requires a Building Notice or installation and sign-off by a
member of a competent persons scheme, even if no new circuit is provided.
