Why “just cut it in June” is the Thanet hedge mistake that attracts a £5,000 fine.
Every June without fail, I arrive to quote a Thanet job and find the hedge has already been cut. Sometimes the owner checked the nesting rules. More often, they did not. The reasoning is always the same: spring is over, the birds must be done by now. Here is what is actually happening in a Thanet hedge in June, and why the fine is not theoretical.
The mistake I quote over, almost every week in summer
Hedges grow fast through late spring. By the end of May most privet, escallonia and hawthorn hedges on the Isle of Thanet have put on two or three inches of new growth. By mid-June they look untidy. The garden needs to look presentable for summer, the DFL owners are arriving, the school holidays are approaching. “Just cut it in June” is the obvious move.
The problem: June is not past nesting season. It is the peak of it.
Myth: “Nesting is a spring thing. By June the birds are done.”
Fact: most common hedgerow birds have two or three broods per season. Blackbirds commonly run three clutches, with the last completing in late July. Dunnocks have two to three broods through the season. House sparrows carry two to three clutches, the last often running into July in sheltered urban hedges. In Thanet's coastal salt-belt hedges, whitethroat and garden warbler, both summer migrants that arrive from Africa in late April, nest actively through until August. The Wildlife and Countryside Act 1981 window runs 1 March to 31 August precisely because of these multi-brood species.
What the Wildlife and Countryside Act 1981 actually says
Section 1 of the Wildlife and Countryside Act 1981 makes it a criminal offence to intentionally kill, injure or take any wild bird, or to intentionally damage or destroy an active nest. “Active” means a nest in use or being built, including a nest under construction with no eggs yet. On conviction in a magistrates’ court: up to £5,000 per offence.
The key point on proof: this is effectively a strict-liability offence once disturbance has been established. “I did not know the nest was there” is not a complete defence after the fact. The obligation is on the person doing the cutting to check first, not to prove ignorance after a nest has been disturbed.
Why Thanet’s coastal hedges nest later than the UK average
Thanet’s salt-belt hedges, from Westgate-on-Sea CT8 through Birchington CT7, Margate CT9, Cliftonville, Broadstairs CT10 and out to Ramsgate CT11/CT12, are ecologically rich nesting habitat. Coastal scrub species that are active well into summer include:
- Dunnock: two to three broods per season, last clutch commonly completing into July on the Thanet coast.
- Blackbird: up to three broods, last brood fledging in late July.
- House sparrow: two to three broods; Cliftonville’s dense terrace hedges and roofline vegetation hold significant house sparrow populations well into July.
- Linnet: two to three broods in coastal scrub, regularly nesting into late July in Thanet’s escallonia and hawthorn belts.
- Whitethroat: summer migrant arriving late April. Nests through May to August in thick coastal scrub. Mature escallonia and griselinia hedges along the Margate and Ramsgate seafronts are typical whitethroat habitat.
- Garden warbler: similar pattern to whitethroat in more sheltered inland scrub, extending nesting into August in the Minster and Monkton fringe.
The practical conclusion: most Thanet coastal hedges have active nests in June. Many have active nests in July. Some, particularly where coastal warblers are present, have active nests into August. The legal window and the biological reality line up closely here.
Wildlife and Countryside Act 1981: the nesting window
Under section 1 of the WCA 1981, it is an offence to intentionally damage or destroy an active nest. The main nesting season for UK hedgerow birds runs 1 March to 31 August. The safe default cutting window for most Thanet hedges is September to late February. Inside the window (March to August), cutting is only permitted after a competent visual nest check confirms no active nesting in the section to be cut. Penalty on conviction: up to £5,000 per offence. For the full wildlife-law picture including hedgehog protocol and the SPA/Ramsar designations around Sandwich and Pegwell Bay, see Nesting, hedgehogs and Thanet’s wildlife law.
What the safe cutting windows actually look like on Thanet
The default: September to late February. By September, the last broods on Thanet’s coastal hedges have fledged. By late February, the first eggs of the season have not yet hatched. For most homeowners on the Isle of Thanet, booking a proper annual cut in this window is the right answer: one full autumn pass, or a late-February formative tidy where needed.
Inside-window work (March to August): if you genuinely need a cut inside the window, the rule is a competent visual check before starting. Walk both sides of the hedge slowly. Look through the outer canopy into the body of the hedge. Listen for alarm calls: adults flying repeatedly to the same point are the giveaway. Look for obvious nest-building activity, dropped moss, feathers gathering at the base. If any active nesting is present in the section to be cut: stop and reschedule that section.
A quick glance from the pavement is not a competent check. For a large mature escallonia in a Cliftonville conservation-area terrace, or a coastal griselinia hedge used by whitethroat, a slower methodical walk on both sides is the standard. If there is genuine doubt, the cost of rescheduling is lower than the cost of a conviction.
In practice: how I schedule Thanet hedge jobs
For inside-window jobs I carry out a check on arrival. If I find active nesting in a section, I work around it where possible (trimming above a clear section, leaving the active section alone) and reschedule the affected area, usually four to six weeks out to let the brood fledge. I do not charge for the check. I flag jobs booked for June or July where the hedge is clearly a likely multi-brood habitat, so clients can decide whether to move the booking to September or accept the check-and-hold process.
The short version for homeowners: book September to February. Plan hedge work in the correct window rather than squeezing it in when the hedge looks bad in June.
For a practical overview of hedge-trimming technique, including cutting method and timing approach across different hedge types, Mark’s House and Garden UK cover the basics accessibly in their “Hedge Trimming for Beginners: 15 Essential Tips for Hedge Cutting” (YouTube, December 2025). Their channel is UK-based and useful for technique. Note that general UK guidance tends toward south-England inland norms; Thanet’s coastal-scrub species pattern makes the full 1 March to 31 August window more relevant here than a purely spring-centric reading would suggest.
