When to prune cup of gold vine in the UK
Why the timing differs here
RHS guidance puts evergreen pruning in mid to late spring, once the risk of a hard frost has passed. Cutting evergreens in a British winter exposes soft new growth to frost damage, which is why the timing sits later here than in milder climates.
How to prune cup of gold vine
Cut the entire vine back by one-half to two-thirds after flowering, removing weak or crossing stems to a strong outward-facing bud. In frost-free climates, a harder renovation cut to 60–90 cm from the base every few years rejuvenates an old vine.
Cup of gold vine is a robust tropical climber that needs annual pruning to keep its size in check and promote flowering. Flowers are produced on new growth, so cutting back hard after the main flush of bloom encourages a second wave and keeps the vine from becoming a tangled mass.

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.
