When to prune cephalotaxus 'fastigiata' 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 cephalotaxus 'fastigiata'
Shorten new growth with hand pruners or hedge shears to maintain the desired columnar profile. The plant tolerates cutting into older wood and will regenerate from bare stems unlike many conifers.
Cephalotaxus harringtonia 'Fastigiata' (Japanese plum yew) is a slow-growing upright shrub that tolerates pruning well but rarely needs it. Its columnar form is natural. Trim to tighten shape or control size in late spring after new growth appears. Remove any dead or damaged stems at any time.

Pruning itself is not illegal, but destroying an active nest is.

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.
