I can not see anyone mistaking a honeysuckle for anything else !

20% of our class last year couldn't identify the lonicera nitida
bagensen's gold and the lemon beauty one. For the later almost everyone
thought it was privet or buxus. Two thought it was cotonoeaster. Also
we don't know what the flowers look like. Little white flowers the OP
said? One should then ask which honeysuckle has little white flowers.

and I have
certainly never come across a climbing Cotoneaster.

I've got two - one trails down and up, following a fence, the other is
spread against a wall, as if climbing )

Out of 180 variety of honeysuckles, the vast majority are bush.

Other thoughts are Lonicera x americana which has the right colour berries
(and is a hybrid of implexa) but this for me flowers all summer and autumn

I'd say the fragrantissima then. A bush that climbs ;o)
