When to prune thunbergia battiscombei 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 thunbergia battiscombei
Cut stems back by one-third to one-half using sharp secateurs, pruning to a healthy node or lateral shoot. Remove any dead, crossing, or very woody stems at the base. Tip-pinch new shoots through summer to build a bushy framework before flowers form.
This vigorous African Thunbergia shrub-climber produces vivid purple-blue flowers and grows quickly. It needs annual pruning to stay manageable and to keep flowering well. Without cutting back it becomes woody and bare at the base. Prune in early spring before new growth begins or immediately after a main flowering flush.

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.
