When to prune primulina 'loki' in the UK
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.

Snap or cut spent flower stalks off cleanly at their point of origin near the leaf axils. Remove any yellowing or damaged leaves by cutting or peeling them away at the base, keeping the rosette open and airy.
Primulina 'Loki' is a compact Gesneriaceae hybrid that needs minimal pruning. Remove spent flower stalks promptly to keep the plant tidy and may encourage further flowering.

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.
