When to prune aeschynanthus pulcher in the UK
Why the timing differs here
For shrubs that flower on the current season's growth, the RHS times pruning to early or mid spring — after severe weather has passed and once the growth buds begin to swell. In Britain that is usually March into April rather than the February common in warmer regions; prune too early and the new shoots meet a late frost.
How to prune aeschynanthus pulcher
Cut spent-flowering stems back by up to one-third, cutting cleanly above a leaf node. Avoid pruning more than one-third of the plant in a single session to limit stress.
Aeschynanthus pulcher (royal red bugler) blooms at stem tips, so prune only after flowers have finished to avoid sacrificing buds. Trimming spent stems by one-third encourages branching and a more compact habit in the following season. Simply remove dead leaves or stems whenever they appear.

Why is UK pruning timing different from American advice?
Most pruning guides online are written for US conditions and anchored to USDA zones. Britain's maritime climate gives milder winters but later, less predictable last frosts — from March in the south-west to mid-May in the north — so the RHS advises against winter pruning for most plants: it pushes out soft growth that a late frost then kills. Britain also has the nesting-bird law, which has no US equivalent.
