I have tried crimps in the past and been thoroughly disillusioned with
them. I have found them unreliable and easily pulled apart, even with
ratchet crimping pliers.

Which suggests that something is not working as it should there. I find
a well made crimp is far harder to pull apart than say a cable in a
screw down terminal. The ratchet crimpers often allow for some
adjustment to the tightness. Also make sure you are using the right type
of *insulated* crimp in them.

Apart from size, I presume there is a range of qualities. I'm sure the
lot I got were from Screwfix.

Is there an alternative convenient and affordable method recommended
where access is not required.

Solder and heatshrink is ok. Start with a mechanical join first (i.e.
twisted or wire wrapped) then solder.

Wago style terminals are also quick and easy - and probably easier to
implement in many more difficult to reach circumstances.

That sounds a simple and attractive solution.
