I was watching a solid floor being filled the other day - they laid what
looked to be 150mm Kingspan board, and then dumped about 6 inches of
concrete on top. So I'd guess (or hope) that it doesn't compress.

AFAIK that is the standard way of laying an insulated floor.

It's pretty rigid stuff

But not a beam/block one; under some circumstances the manufacturer does
recommend battens to prevent sagging, but it looks as though that's only
where it's covered by a timber floor, rather than a screed

extruded polystyrene is cheaper than kingspan, and almost as good an
insulator and doesn't catch fire in a screed.

My floor was installed in July '15 with Ballytherm in the floor. Has already
sank 20-30mm. Can see the gap under skirting board and grout line where floor
tiles were before and after sinking. Any redress for this by the way or advice
on how to deal with it?

Underfloor(concrete) insulation is special foam, less compressible than the normal stuff.
They have used the wrong foam.
Mine hasn't moved at all.

I could be bothered to reply, if you could be bothered to quote some
context...

Sounds like the builders laid insulation right on top of the beam
and block surface, which they hadn't bothered to overscreed (so that
the insulation lies on a dead flat surface). The tops of the beams
would be a bit proud of the blocks and the whole floor structure
has sagged between the beams. either that or they used cheap expanded
polystyrene slabs which don't like getting wet (and did get wet during
construction), or high traffic areas like doorways, or the bit in front
of the sink.

Sue the builders is the only solution, except this sounds like
Ireland, where dodgy builders are commonplace, in which case go round
with some mates and kick shit out of him.

Which the Ballytherm website says is an acceptable installation method.

Every time I see a house being built near me (SE England) using beam and
block, they *always* pour/brush screed over the structure for some
reason, and it makes no sense to have rigid insulation effectively
supported on the high spots, i.e. the slightly proud ridge along
the tops of the beams.

If the upper surface of the blocks is flush with the tops of the
beams then no screeding would be necessary, but we don't know
what happened to the OPs property during construction. All we do
know is that the subfloor is flexing and/or sagging making his
floor tiles crack.

BAllythem sounds like Ireland and dodgy builders are commonplace.
I worked with a guy from Southern Ireland and the stories he told
me about builders and planning violations were hair-raising.

Resolve what?

Perhaps just a hint as to what you are talking about?

It sure would help. Floor insulation sinking.

OP: You can't unsink it. So your options are very few.

See a solicitor. Seems that the maker of the foil-backed
PIR insulation was supplied with some duff chemicals.

Sarah Beaney showed a sprogram where some soert of injected
foam could be used to repair subsidence. Not sure if this
could be used internally.

If you managed to inject it with enough precision to miraculously get the floor level again, it's still sitting on top of gradually collapsing insulation. I'd not consider that a satisfactory repair. Replace & maybe sue seems the only realistic option, or live with it as is.

You can live with it *and* sue. You don't have to actually do the
repairs to get damages amounting to what the repairs would cost. The
same as if your car is written off in an accident you don't need to use
the insurance money to buy a new car.

Built a new build house in Essex 2 years ago and have had the same thing happen to my house.

Ballytherm Insulation foam which has sunk by almost an Inch in places on a block and beam floor.

Developer wants to jack the floor up using a firm called Geobear rather than replace the product which has failed and no longer insulating my home.

Absolute bodge job!
