When to prune douglas's sinningia 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.
How to prune douglas's sinningia
Deadhead spent blooms; cut back leggy stems to a healthy bud or node.
Prune douglas's sinningia mainly to shape it and encourage more blooms. Deadhead spent flowers through the season, and carry out any harder structural pruning at the plant's dormant or post-flowering window to avoid cutting off the next round of buds.

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.
