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.

Prune with care — PeeWee is an oakleaf hydrangea that blooms on old wood. Heavy pruning removes next year's flower buds. Limit pruning to removing dead wood and spent flower heads. Light shaping can be done right after flowering ends in summer; avoid cutting in late summer, autumn, or winter.

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.
