Most new houses have a 12 month guarantee on all fittings. Check
this out.
If you suspect you have no inhibitor Sentinel X-100 for instance,
then
partially drain, install X-400 sludge remover, and then after
removing after
a few weeks in the heating season flush out twice and fill with
X-100. Best
do it now before corrosion takes hold.

that's a bit more extreme than I intended!

Good old IMM

The water that comes out
is completely clear so is it likely there is any sludge to remove?
it's only had 1 winters use.

If the water is clear then it indicates that there almost certainly was
some inhibitor in there (the stuff I have had is clear IIRC) I'd have
thought as IME you can get some coloration at least quite quickly -
certainly after a year. You get a black coloration in the water from the
corrosion products.

Anyway, no I wouldn't think sludge remover is worthwhile here. But it
will be worthwhile adding some inhibitor anyway, then at least you know
that has been done properly.

Add some Fernox or Sentinel inhibitor from your local DIY shed or
Plumbers Merchants.

If you have an open system with a header tank you can just add it to
there.

Fernox do one in syringe that you can use to inject it into a rad. I
fitted a suitable threaded fitting to a piece of Hep2O pipe (flexible
plastic pipe), threaded that into the threaded hole at the top of the
rad, funnel in the end and then pour it in.

If you have a column type rad in the bathroom with the bleed valve on
top you can just stick the funnel in the top of that.
