When to cut a hedge on Teesside, and the rules that apply

Last updated: August 2026.

The law comes first

Under the Wildlife and Countryside Act 1981 it is an offence to intentionally take, damage or destroy the nest of a wild bird while it is in use or being built. There is no legal date range that makes hedge cutting automatically safe or automatically illegal for a domestic garden hedge, but the practical reality is that most nesting happens between March and August, and hedges are prime nesting habitat.

That means one thing in practice: check before you cut. A careful inspection of a domestic hedge takes a few minutes, and if there is an active nest the work waits. Any contractor who declines to look is putting your name on the problem, not just theirs.

The Teesside calendar

The region runs a slightly later season than most national guidance assumes. Growth starts in the second half of March, peaks in June, and slows through September.

• March to May: avoid where possible. Peak nesting, and cuts made now produce fast soft regrowth that needs doing again by July.
• June: the first formal cut for privet and fast evergreens, checked carefully for nests first.
• Late August to early October: the main cutting window for almost everything. Nesting is over, growth is slowing, and the cut holds its shape into spring.
• November to February: deciduous and native hedges cut while dormant, when the structure is visible and there is no wildlife risk.

Cutting evergreens in hard frost is best avoided, since frozen foliage tears rather than cuts and the exposed edges brown off.

Leylandii, and the one rule that matters

Leylandii will not regenerate from bare brown wood. Cut into it and that face stays brown permanently. Every reduction therefore has to stop while green growth remains on the branch, which sets a hard limit on how far a tall hedge can come down in one go.

Where a hedge has been allowed to reach five or six metres, that limit sometimes means the honest advice is removal and replanting rather than reduction, because the height you want and the height the plant will survive at are no longer the same number. Getting that assessed before booking saves a great deal of disappointment.

High hedges and neighbours

Part 8 of the Anti-social Behaviour Act 2003 gives councils a role where an evergreen hedge over two metres blocks light to a neighbouring property. It is a last resort: the council will expect evidence that the neighbours have genuinely tried to resolve it themselves, and there is a fee to bring a complaint. Both Middlesbrough and Stockton operate the scheme like every other English council.

Overhanging branches are separate. You may cut back to your boundary line, but the cuttings belong to the hedge owner and should be offered back rather than launched over the fence. Cutting beyond the line, or into the hedge in a way that kills it, moves the situation from tidy gardening into a civil dispute.

Shape, taper and why hedges go bare at the bottom

A hedge should be cut with the sides tapering very slightly inwards from base to top, so light reaches the bottom growth. Cut with vertical or, worse, flared sides, the top shades the base and the hedge thins out underneath within a few years. That single detail is the most common reason an established hedge looks thin at the bottom, and it is fixable only slowly.

Cutting a little and often keeps a hedge tight. Letting it run for three years then reducing it hard produces a stressed hedge with visible cut stubs that take a full season to green over. Costs and timing for the work itself are on the hedge cutting page, and larger volumes of hedge waste are covered under clearance.
