Home › Guides › Hedge cutting: when to cut, and the law on nesting birds
Hedge cutting in the UK is governed by several overlapping legal frameworks designed to protect nesting birds, preserve important hedgerows, and resolve disputes over hedge height. Understanding when you can cut your hedges, what protections apply, and which regulations cover your situation requires knowing the distinction between domestic hedges (private property hedges around homes), countryside hedges (on or bordering agricultural and designated land), and high hedges that have become a matter between neighbours.
Nesting bird protection: the Wildlife and Countryside Act 1981
It is an offence under the Wildlife and Countryside Act 1981 to intentionally damage or destroy the nest of any wild bird while it is in use or being built. The Act specifically applies to nests that are actively in use or being built, so the offence is committed only if a nest is occupied at the time of damage or destruction.
The active nesting season is broadly 1 March to 31 August, though birds can and do nest outside this window in mild years. The RSPB recommends treating this period as a no-cut window for any significant hedge work. While technically you may legally cut between these dates if you first inspect the hedge and confirm no active nests are present, the practical difficulty of spotting every nest makes this approach risky.
The safest approach is to complete any substantial hedge cutting—renovation, hard pruning, or removal—between 1 September and 28 February. Routine maintenance trimming outside the March to August period is therefore best practice.
Timing by hedge type
Different hedges respond to cutting at different times, and timing also affects their appearance and function:
Hawthorn: Flowers on old wood in May, so avoid cutting before May if you want spring blossom. One annual cut in September is typical for informal hedges; formal hedges may receive a second trim in February to maintain shape.
Beech: Cut once yearly in August to lock in the russet-brown winter foliage that gives beech hedges their characteristic appearance. Never cut later than mid-September. For renovation or hard pruning, January to February is ideal when plants are dormant and birds have not begun nesting.
Conifer hedges (including Leylandii): Trim two or three times during the growing season between April and August, outside the peak nesting season of March and May. Never cut back into old brown wood, as most conifers—particularly Leylandii and Lawson’s cypress—will not regrow from it. Regular light trimming prevents the need for drastic cutting.
Mixed native hedges: One or two cuts annually in September, with an optional February trim for formal hedges. Avoid cutting in March and May if possible, as native hedge species (hawthorn, blackthorn, holly, field maple) support nesting birds and spring flowers.
High hedges and neighbour disputes
If a hedge is causing a serious problem for a neighbour—blocking light, access, or enjoyment of their property—and the hedge owner refuses to remedy it, the neighbour can lodge a complaint with the local council under Part 8 of the Anti-social Behaviour Act 2003.
A “high hedge” is defined as a barrier to light or access formed wholly or predominantly by a line of two or more evergreens, rising to more than 2 metres above ground level. Deciduous hedges and hedges below 2 metres are not covered by this legislation.
Before approaching the council, the complainant must attempt to resolve the matter by speaking to the hedge owner directly and then writing to them. Only after these steps have failed should they contact the local authority. Wiltshire Council, like most local authorities, charges a fee of £600 (rising to £650 from April 2026) to investigate a high hedge complaint. The council must first decide whether the hedge height is actually adversely affecting the neighbour’s reasonable enjoyment of their property; if it is, they may issue a “remedial notice” ordering the hedge owner to cut it to a specified height, usually 2 metres.
Appeals against the council’s decision are possible by both the complainant and the hedge owner. The council will not consider complaints about hedge roots under this legislation, only the height of the above-ground structure.
Hedgerow Regulations: countryside hedges
The Hedgerows Regulations 1997 protect hedgerows on or adjoining agricultural land, common land, nature reserves, and other designated areas. These regulations do not apply to hedges within the gardens of dwelling houses (domestic hedges), but they do apply to many rural hedges in Wiltshire and surrounding counties.
Before removing a countryside hedgerow of more than 20 metres in length, or any shorter hedgerow meeting another at each end, the owner must submit a “hedgerow removal notice” to the local planning authority at least six weeks in advance. The authority then has 42 days to decide whether to issue a “hedgerow retention notice” preventing removal. Retention notices can be issued only for hedgerows deemed “important”—those existing for 30 years or more and meeting ecological, archaeological, or landscape criteria set out in the Regulations.
Certain removals are allowed without notice, including those for access openings, emergency work, flood defence, development with planning permission, and pest eradication. However, unauthorized removal of a protected hedgerow is a criminal offence with substantial fines. Unauthorized removal of an important hedgerow can also result in the local authority ordering replanting at the owner’s expense.
If you own or manage land with hedgerows and are considering any removal, consult your local planning authority first to establish whether the Regulations apply.
Practical guidance: cutting your own hedge safely and legally
For domestic hedges on your own property:
- Plan any substantial work (hard pruning, renovation, removal) between 1 September and 28 February to avoid risk of harming nesting birds
- If you must cut between 1 March and 31 August, inspect the hedge carefully for active nests beforehand. If nests are present, wait until September
- Follow the recommended cutting schedule for your hedge type: beech in August, hawthorn in September (or February for formal shapes), conifer hedges in April to August with light regular trims
- Do not cut back into brown wood on conifers; they will not regrow
If you hire a contractor to cut your hedges, ensure they understand these timing requirements and confirm they will work within the nesting season constraints.
Key points
- It is an offence under the Wildlife and Countryside Act 1981 to damage or destroy an occupied nest; avoid cutting hedges between 1 March and 31 August as best practice
- Cut hawthorn in September or February (for formal shape) to protect spring blossoms; cut beech once yearly in August to preserve russet winter colour
- Conifer hedges need regular light trimming in April to August; never cut into brown wood
- High hedges (evergreen, over 2 metres) causing neighbour disputes can be addressed through Wiltshire Council (fee £600–£650) after direct attempts to resolve the problem fail
- Before removing a hedgerow on agricultural or designated land, notify the local planning authority at least six weeks in advance; “important” hedgerows (30+ years old, meeting ecological criteria) cannot be removed without consent
