When to prune hedera colchica 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 hedera colchica
Use sharp secateurs to cut back overlong or damaged shoots to a healthy bud or lateral stem. For hard renovation, cut all stems back to 30–60 cm from the base — Persian ivy re-shoots reliably.
Hedera colchica (Persian ivy) is a vigorous climber that needs regular pruning to control its spread and keep growth tidy. Prune hard in late winter or early spring before new growth begins. Remove wayward, weak, or frost-damaged stems. Cut back overlong shoots to a healthy bud to maintain the shape and size you want.

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.
