Domestic Hedge Cutting Rules UK: What the Law Says

Cutting hedges incorrectly can break the law. I find that often surprises people when it comes up. The rules on cutting hedges in the UK are spread across a few different laws. Most people only find out about them when a neighbour complains or a bird's nest stops the job halfway. As a tree surgeon I follow these rules every day. The following applies wherever you may be in the UK.

Quick summary of the hedge cutting rules

Nesting birds — the rule that covers every hedge

Under the Wildlife and Countryside Act 1981 it is an offence to damage or destroy a bird's nest while that nest is in use or being built. It applies to every hedge, garden or field, everywhere in the UK, every day of the year. Check before every cut.

There’s no closed season for a garden hedge

The Act works on whether a nest is there, not on dates. A domestic garden hedge can lawfully be cut at any time of year provided there’s no active nest in it. September to February is the safest window because that’s when you’re least likely to find one.

1 March to 31 August is a farming rule

Hedgerows on agricultural land have a separate closed period running from 1 March to 31 August, and it applies whether or not a nest is present. That’s an obligation on the land manager. It doesn’t apply to a hedge in a domestic garden.

Taking a countryside hedgerow out is controlled separately

The Hedgerow Regulations 1997, in England and Wales, control the removal of hedgerows in the countryside, mainly those on or adjoining agricultural land. They’re about removal, not trimming, and they don’t cover a hedge within the boundary of a house.

Branches overhanging your side

You may cut what overhangs your property, back to the boundary line and no further. You must not cut anything on your neighbour's side, and you must offer the cuttings back. Check for nests before you start.

A hedge that’s too tall

You can complain to the council under the High Hedges provisions in Part 8 of the Anti-social Behaviour Act 2003, in England and Wales. Know what that gets you: a remedial notice cannot require the hedge to be reduced below two metres, and it cannot require the hedge to be removed.

If you get it wrong

Damaging or destroying an active nest is a criminal offence carrying an unlimited fine and up to six months in prison, plus a criminal record.

Each of these is covered properly below, along with the cutting season for each hedge species and what to do about a neighbour's hedge.

The Wildlife and Countryside Act 1981

The main law is the Wildlife and Countryside Act 1981. It says you can’t intentionally damage, destroy, or obstruct a bird's nest while it’s being built or in use. For hedge cutting, this means you can’t cut a hedge with an active nest in it.

The nesting season is generally March to August. But birds don’t follow a calendar. I have seen wood pigeons nesting in February during a mild winter. Some species nest into September. The law doesn’t give fixed dates. It says: if there’s a nest, you leave it alone.

So the practical rule is simple: check the hedge before every cut. Even in December. If a contractor starts cutting without looking for nests, they’re breaking the law. We check every hedge we’re asked to trim. If we find a nest, we mark that section and come back after the birds have gone. There’s no exception for convenience.

Does the law apply to garden hedges?

Yes. The nesting bird protection covers every hedge. A privet hedge in a back garden has exactly the same standing in law as a hawthorn field boundary, and the same check has to be done before either one is cut. What differs is everything else. The rules written for farmland hedgerows don’t reach into a domestic garden, and that’s where most of the confusion on this subject comes from, so it gets its own section next.

Can you cut a hedge at any time of year?

If it’s a garden hedge, yes. There’s no closed season for domestic hedge cutting. You can cut in May if you need to, provided there’s no active nest in the hedge. The only date that matters is the day you look at it.

The Wildlife and Countryside Act 1981 works on the presence of a nest, not on the calendar, and it is in force every day of the year. A nest in February is protected in exactly the same way as a nest in June. So the question to ask isn’t "is it nesting season", it’s "is there a nest in this hedge today".

Where the 1 March to 31 August dates actually come from

Those dates get quoted at homeowners constantly, and they’re being quoted out of the wrong rulebook. The 1 March to 31 August closed period applies to hedgerows on agricultural land. It is an obligation on the land manager, it is enforced against farms, and within that window it bites whether or not there’s a nest in the hedge.

A hedge in a domestic garden isn’t on agricultural land and isn’t covered by it. Nor is it covered by the Hedgerow Regulations 1997, which control the removal of countryside hedgerows and don’t extend to a hedge within the boundary of a house. If your hedge separates your garden from next door's, neither of those rules is about you.

What that means in practice: nobody can tell you that cutting your own garden hedge in June is illegal, because it isn’t. What they can tell you, and they would be right, is that June is the month you’re most likely to find a nest in it, and that cutting through an active nest is a criminal offence.

The window we work to, and what we do outside it

September to February is the safe window and it’s when most domestic hedge work gets done. Not because the law sets those dates, but because the chance of finding an active nest is lowest and the job doesn’t get stopped halfway through.

Outside that window we still cut, and we still check first. We walk the length of the hedge, looking and listening. If there’s a nest we mark that section, cut the rest, and come back for the marked length once the birds have fledged. Birds don’t follow the calendar either way, which is why the check matters more than the date does.

The fine if you get it wrong

Disturbing nesting birds is a criminal offence. You can face an unlimited fine and up to six months in prison. In practice, it usually means a fine of several hundred or thousand pounds and a criminal record. The RSPB will investigate. But more often, it’s the neighbour who reports it. A dispute over a hedge cut at the wrong time is one of the most common neighbour complaints I hear about.

What about the neighbour's hedge blocking your light?

This is one of the questions I get asked most. Your neighbour's hedge is growing over the boundary, blocking your light, encroaching on your garden. What can you do?

You can cut any branches that overhang your property, right up to the boundary line. You must not cut anything on their side. You must offer the cuttings back to the neighbour. They can say no, but you’ve to ask. Throwing them back over the fence is fly-tipping. And before you cut, check for nests. The same law applies.

If the hedge is so tall it blocks light to your windows, you may be able to complain to the local council under the High Hedges provisions in Part 8 of the Anti-social Behaviour Act 2003. These apply in England and Wales, and only to a line of two or more mostly evergreen or semi-evergreen trees or shrubs acting as a barrier to light or access.

What the council can and can’t order

This is the part people usually get wrong. If the council upholds the complaint, it issues a remedial notice telling the owner what to do about the hedge. That notice cannot require the hedge to be reduced below two metres, and it cannot require the hedge to be removed. So a complaint is a route to getting a very tall hedge brought down to a manageable height. It isn’t a route to having it taken out.

There’s usually a fee, commonly £300 to £500 depending on the council, and the process takes months. The council will also expect to see that you’ve tried to settle it with your neighbour first. Talk to them before you spend anything. In practice a tree surgeon can often reduce the hedge from your side, or agree a reduction with both parties, faster and for less than the complaint fee.

Hedge cutting seasons by species

Conifer hedges (Leylandii, Thuja etc.). Two to three cuts per year. First cut in late May after the last frost. Second in late summer. Never cut conifers back to bare wood. They don’t regrow. The brown patches stay forever.

Mixed native hedges (hawthorn, blackthorn, hazel). One cut per year in late winter, January or February. This keeps the hedge dense and healthy without disturbing nesting birds or removing flowers and berries.

Privet. Two cuts per year. Late spring and late summer. Privet grows fast and goes leggy if left alone. Regular trimming keeps it dense.

Beech and hornbeam. One cut per year in late summer, August. Beech holds its dead leaves through winter if trimmed then, giving you year-round privacy.

Box. One cut in June or July on a dry day. Box blight is a risk. Clear all clippings.

How we cut hedges in the North East

Every hedge cut starts with a nest check. We walk the length of the hedge, looking and listening. If we find a nest, we mark it, leave that section, and come back after the birds have left. This isn’t optional. It’s the law, and it’s the right thing to do.

In County Durham, spring comes later than the south. We don’t cut conifers before the last frost because the new growth will burn. Native hedges get their winter cut in February, just before the sap rises.

What hedge cutting costs

Hedge trimming starts around £120 for a standard garden hedge. Large lengths, tall conifers or overgrown reductions cost more. A conifer hedge that gets two cuts a year is cheaper per cut than one cut on a hedge neglected for three years. Regular maintenance costs less than crisis management. Written quote before any work starts.

Can I cut my hedge any time of year?

Yes, provided no birds are nesting in it. The law doesn’t set fixed dates for garden hedges. Check first, cut second. The safest window is September to February.

What happens if I cut a hedge with birds nesting in it?

You’re committing a criminal offence. Maximum penalty is an unlimited fine and up to six months in prison. In practice, fines range from several hundred to several thousand pounds. The RSPB investigates and prosecutes.

Can I cut my neighbour's hedge overhanging my property?

You can cut branches that overhang your boundary, up to the property line. You must offer the cuttings back. You can’t cut anything on their side. Check for nests first.

How much does hedge cutting cost in County Durham?

A standard garden hedge starts around £120. Large hedges, tall conifers or neglected hedges cost more. Written quote before we start.
