When to prune bleeding heart vine 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 bleeding heart vine
After blooming, cut all stems back to within 2–4 nodes of the base or structural framework. In spring, as new growth begins, pinch out each shoot tip once it has produced 3–4 node pairs to encourage branching. Train the resulting shoots onto a trellis or hoop support.
Bleeding Heart Vine blooms on new growth and becomes rank without pruning. Cut back hard after flowering ends in autumn or in late winter before growth resumes. Regular tip-pinching in spring builds a denser plant with more flowering shoots. Vigorous plants may need a second light trim mid-season.

Is it illegal to prune bleeding heart vine in spring or summer in the UK?
Pruning itself is not illegal, but destroying an active nest is. Under the Wildlife and Countryside Act 1981 it is a criminal offence to damage or destroy the nest of any wild bird while it is being built or in use, and the RHS treats the nesting season as March to August, sometimes longer.

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.
