When can you cut hedges in the UK? Nesting season rules explained
Highveld Landscapes · 11 June 2026
Every spring we get the same call from customers across Shrewsbury: “Can you still cut my hedge, or is it illegal now?” It's a fair question, because the rules are widely misunderstood — so here's the straight version.
What the law actually says
There is no law that bans hedge cutting between March and August for garden hedges. What the law does say — under the Wildlife and Countryside Act 1981 — is that it's an offence to intentionally damage or destroy the active nest of any wild bird, or to disturb birds while they're building or sitting on a nest.
In practice, that means a hedge with an active nest in it can't be cut until the chicks have fledged. The main UK bird nesting season runs roughly from March to August, which is why responsible gardeners treat those months with care — not because cutting is banned, but because nests are likely.
Before any cut between March and August, we check the hedge carefully. If there's an active nest, the job waits — we'll tell you straight and come back when it's safe. Most of the time a sensible workaround exists, like trimming the unaffected faces and returning for the rest.
The best months to cut, by hedge type
Formal evergreen hedges like box and yew are usually best trimmed in early summer and again in early autumn. Conifer hedges like leylandii should be cut up to three times during the growing season (April to August, nest checks done) and never hard back into brown wood, because most conifers won't regrow from it.
Deciduous hedges like beech and hornbeam take their main cut in late August, with a tidy-up in winter. Native mixed hedging is best cut in late winter (January and February) — after the berries have fed the birds, and before nesting starts.
If a hedge has got badly overgrown, late winter is the time for hard renovation work, and some species need it staged over two or three years. We'll tell you honestly what your hedge can take.

Quick answers
- Is it illegal to cut hedges between March and August?
- No — for garden hedges there's no blanket ban. It is illegal to damage or destroy an active bird's nest, so hedges must be checked before cutting during nesting season (roughly March to August). If there's an active nest, the cut waits until the birds have fledged.
- How often should a leylandii hedge be cut?
- Two to three times a year during the growing season. Little and often is the rule — leylandii won't regrow from old brown wood, so letting it get away from you and then cutting hard back leaves permanent bare patches.
