When to prune milkflower cotoneaster 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 milkflower cotoneaster
Use loppers or a pruning saw to remove dead and crossing stems at their point of origin. For light shaping, cut back overlong shoots to a strong side-branch. Avoid shearing which destroys the graceful arching form.
Milkflower cotoneaster is a large, naturally well-shaped evergreen shrub valued for its arching form, white flowers, and long-lasting red berries. It needs little pruning. Remove dead, diseased, or crossing branches in late winter. Lightly trim to shape if space is limited, but avoid heavy cutting which spoils the natural habit.

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. Check milkflower cotoneaster for nests before cutting, and if you find an active one, leave that part of the plant until the birds have fledged.

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.
