The wildlife law that protects nesting birds – By expert hedge cutters in Glasgow
The Wildlife and Countryside Act 1981 is the law that matters most for a domestic hedge, and it has nothing to do with farming.
It makes it an offence to intentionally damage or destroy the nest of any wild bird while that nest is in use or being built.
The same rule applies whether the nest sits in a garden hedge, a farm hedgerow, or a tree, and it covers eggs as well as the nest itself. In practice, that means you must not cut into a section of hedge if doing so would disturb an active nest.
When domestic hedge cutting carries the most risk
Most birds nest between March and August, which is why that window carries the real risk, even though the Act itself sets no fixed dates.
The RSPB uses that same window as its practical guide, for exactly this reason.
Outside that window, a hedge is less likely to be hiding an active nest, though it’s never fully guaranteed.
Checking before you cut
The simplest way to avoid cutting into an active nest is to check first.
Walk the hedge, watch for birds flying in and out, listen for alarm calls, and part the foliage carefully to look for a nest.
Find one, and the fix is straightforward.
Leave that section alone, trim around it, and come back once the chicks have fledged, usually a matter of weeks. The rest of the hedge is fine to cut as normal.
The law still allows for cutting and trimming during nesting season, provided no nest gets disturbed.
You’re free to cut or trim a hedge at any other point in the year, no permit required. A proven breach carries an unlimited fine.
When hedge cutting law turns into a boundary dispute
Tall hedges are perfectly legal in Scotland.
The High Hedges (Scotland) Act only steps in once a hedge blocks light and a neighbour makes a formal complaint about it.
The High Hedges (Scotland) Act 2013
The High Hedges (Scotland) Act 2013 covers boundary hedge disputes.
It applies to any hedge formed mainly of two or more trees or shrubs, evergreen, semi-evergreen or deciduous, that clears the two-metre height threshold and blocks a reasonable amount of light to a neighbouring house or garden. Beech and hawthorn hedges are covered just as much as leylandii.
How a high hedge complaint works
A neighbour can’t go straight to the local council. They have to try resolving it informally first, and only apply for a high hedge notice once that’s failed.
If the council upholds the complaint, it can order the hedge cut back, usually to two metres, with a deadline attached.
Miss it and you’re in breach of the rules, risking a fine for non-compliance or the council carrying out the work themselves and recovering the cost from the hedge owner.
An overgrown hedge on its own isn’t breaking the law.
Getting it to meet the rules before a complaint is ever lodged avoids the cost and hassle of dealing with a notice after the fact.
Whose job is it to cut
Whoever owns a boundary hedge is responsible for keeping the whole thing in check, including the side that grows into next door.
A neighbour has the right to cut back branches that cross the boundary onto their own property.
They can’t enter your garden to do it, though, and any cuttings technically belong to the hedge’s owner.
The best time to trim hedges, by type
The right cutting season depends entirely on the type of hedge you’ve got, and on how established it already is.
Formal, conifer, and deciduous hedges
Formal hedges like beech, privet, or box need cutting back once or twice through the growing season to hold their shape, ideally in late spring and again in late summer once new growth has hardened off.
Cut too early and you’re trimming the same soft growth twice.
Fast-growing conifer hedges need more frequent attention, sometimes two or three cuts a year, because they lose density fast if left unchecked for even a single season.
Deciduous hedges like hawthorn or hornbeam are more forgiving. One cut in late summer or early autumn, once the bird nesting season has finished, usually keeps them tidy right through winter.
Evergreen hedges often need a light shape-up even in a mild Scottish winter, when deciduous types are dormant and best left alone.
Established and overgrown hedges
An established hedge that’s already at the height you want just needs cutting back to hold that shape, a quick job compared with what comes next.
An overgrown hedge is a different task entirely.
Hard renovation pruning is safer left to someone who knows how far back a specific species can be cut without leaving permanent bald patches in the old wood.
A hedge trimmed on a regular schedule rarely needs that harder renovation cut at all. Large hedges left unchecked for years are usually the ones that do.
Tools and hedge maintenance
A cordless hedge trimmer handles most garden hedges without trailing a cable across wet grass, and it’s worth choosing one with a blade length that matches your hedge rather than the biggest model on the shelf.
Hedge shears still do a better job on formal, tightly clipped hedges, where a powered trimmer can tear the leaf edges and spoil an otherwise clean line.
Clean the blades between hedges if you’re working on more than one, since sap and plant debris can carry disease from a sick hedge to a healthy one.
Whatever you use, clear up once you’ve finished cutting the hedge.
Garden waste can usually go in a council collection or the local recycling centre. Leaving it in a heap against the hedge just encourages pests and disease.
Common questions about hedge cutting rules
Can I report my neighbour for cutting their hedge?
If they’ve disturbed an active bird’s nest, yes. That’s a wildlife crime and can be reported to the police or the RSPB. If the complaint is about height or light rather than nesting birds, the right route is a high hedge complaint to your local council.
How often should I trim my hedge?
It depends on the species. Fast growers like leylandii need cutting two or three times a year. Slower, formal hedges usually need one or two trims, and established native hedges can often get by with a single cut in late summer.
Is it illegal to cut hedges in summer?
Not automatically. Cutting is legal at any time of year, provided you’re not disturbing an active nest. Summer just happens to overlap with peak bird nesting season, so it’s the time to check most carefully.
Do I need to cut my hedge on my neighbour’s side?
You’re responsible for the whole hedge if you own it, including the side overhanging next door. Your neighbour can trim back growth that crosses the boundary onto their property, but the hedge itself remains yours to maintain.
