When to prune aluminum plant (watermelon pilea) in the UK
Why the timing differs here
British pruning timing is set by the last frost rather than the calendar. The RHS advises against winter pruning for most plants because it pushes out soft growth that a late frost then kills — and UK last frosts run from March in the south-west to mid-May in the north.

Pinch out the top 1–2 nodes of each stem with your fingers or scissors every few weeks during active growth. For leggy plants, cut stems back to 5–10 cm above the soil in spring.
Aluminum Plant grows quickly and becomes leggy without regular pinching. Prune it often to maintain a bushy, compact shape.

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.
