OK so I have finally reached the coupling up the basin taps stage. Sadly
the advance purchase of 15mm cu to 1/2" tap are all female fittings
where the poxy flexible tails need male couplers. I think Toolstation do
something suitable but delivery only.

Also do tapered thread fittings exist anymore? I have a set of bath taps
with a single spout outlet. The connections appear to be parallel thread
female 1/2".

Can't help on Q1 as i've never used flexi tails.

I've always found taps to have male parallel connections and need the
tap connector with a thin fibre washer to seal on the end of the tail
rather than the thread itself.

I usually use a 15mm compression / compression service valve... take the
nut and olive off the tap end, and screw the flexi tail nut straight
onto the valve. The tap nut should include a rubber seal in the nut.

Also do tapered thread fittings exist anymore?

They do. Sometimes required for gas work, but seldom for water.

Unusual for a bath tap IME.

You can get male 1/2" bps to compression adaptors that also have a
flange. That will allow an O ring to go round the thread and make a seal
against the base of the tap.

Alternatively you could use a taper fitting and PTFE if you preferred.

Yes. I haven't described this well. See answer to John.

Inadequate description. This is a wall mounted bronze? casting for
filling over the bath side.

Or even a parallel one with lots of PTFE:-)

Are they a major problem? I was thinking they might be easier when I
come to renew some taps as part of tarting up the bathroom that I put in
mid 80s

Tips and gotchas welcome

There was a fairly negative thread a bit back. Significant failure rate
and some concern about imports not meeting wra spec. Probably not well
suited to low pressure systems.

Twisting during fitting can be tricky. IANAP

Ah, the spout is separate from the tap bit...

Something like:

Yup, it will work, but never feels as solid as a taper fitting.

Taps use a parallel thread with a fibre washer to seal - don't over
tighten. The washer will swell when wet and improve the seal. I usually
do "finger tight" then a bit with a spanner.

In my neck of the woods there are plans afoot to switch over to ¼" high
pressure pipes. Makes a good deal of sense, but I suspect adoption will
be a very slow process.

Spot on! The thread is the clamping device and has no bearing on the seal -
(PTFE not needed). The fibre washer is the key to making the seal. Clean
faces and new washer.

They aren't going to give anywhere near the flow you get from existing
15mm high pressure pipes.
