When to prune raspberry 'heritage' 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.
How to prune raspberry 'heritage'
Cut all canes flush with the ground using loppers or secateurs. Clear away and dispose of old canes (do not compost if disease is present). Thin emerging new canes in spring to 10–15 cm (4–6 in) apart, keeping the strongest upright canes and removing weaklings.
Heritage is an autumn-fruiting (primocane) raspberry — it fruits on the current season's canes. After harvest, cut ALL canes down to ground level in late winter. This is the simplest pruning regime of any fruiting cane: no need to identify old versus new canes. New canes will grow in spring and fruit from late summer into autumn.

Is it illegal to prune raspberry 'heritage' in spring or summer in the UK?

How often does raspberry 'heritage' need pruning in a British garden?

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.
