When to prune meadow blazing star 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 meadow blazing star
Cut spent flower spikes back to basal foliage after bloom if tidiness is preferred, or leave for wildlife. In late winter, cut all stems to within a few inches of the ground to make way for fresh growth.
Meadow Blazing Star benefits from deadheading spent flower spikes to tidy the plant, though the seed heads attract goldfinches so many gardeners leave them through winter. Cut stems back to the ground in late winter or early spring before new growth emerges from the corm. Pruning needs are minimal overall.

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.
