Three conservation areas, one six-week notice, and one £20,000 fine.
If your Broadstairs garden sits inside one of the town's three conservation areas, Thanet District Council's tree rules pick up where ordinary garden law leaves off. Much of Broadstairs' Victorian and Edwardian core is inside a CA. Most homeowners don't know it. Here is the short version of what it actually means for hedge work — and the shorter list of what it doesn't.
Conservation areas have been a fixture in English planning law since the Civic Amenities Act 1967. They protect the look and feel of an area, not just individual buildings — which is why the rules sweep up trees as well as bricks. Thanet District Council looks after three of them in Broadstairs:
- Broadstairs Conservation Area — originally designated 5 June 1970. Extended 1986. Extended twice more — a North extension and a South extension — both on 23 July 2009.
- St Peter's Conservation Area — designated 13 April 1973.
- Reading Street Conservation Area — designated 13 April 1973.
Three things worth knowing about that list. First, North Foreland, Stone Bay and Pierremont are not standalone conservation areas — parts of them fall inside the Broadstairs CA (particularly the 2009 extensions), but not the whole neighbourhood. Second, Article 4 directions — the extra layer of planning control that some Kent councils lay over CAs — do not apply anywhere in Broadstairs. That is Ramsgate territory. Third, if you are unsure whether your address is in one, the Thanet DC mapping layer is the authoritative answer. Search the postcode on the council's planning portal; if your plot falls inside a coloured CA polygon, you are in.
The actual rule, in plain English
Inside a conservation area, you must give Thanet District Council six weeks' written notice before you can prune, lop, top or fell any tree with a stem over 75mm in diameter measured at 1.5 metres from the ground. This is set out in section 211 of the Town and Country Planning Act 1990 — hence the "s.211 notice" contractors mention.
The council has six weeks from receipt of your notice to either do nothing (in which case you can proceed) or to slap a formal Tree Preservation Order on the tree (in which case a separate consent application is needed). In practice, well over nine times out of ten on a routine hedge job, the six weeks pass without comment and the work goes ahead.
What does 75mm at 1.5m actually look like?
About the diameter of a half-litre water bottle, measured at chest height. A thick holm oak or a mature yew standard clipped into a hedge for decades almost certainly qualifies. A privet stem in the body of a young hedge almost certainly doesn't. Multiple stems in a single hedge — each measured separately at 1.5m — can collectively push you over the line. Always worth a tape measure before a quote.
The £20,000 fine
The reason this matters: unauthorised works to a protected tree in a conservation area (or a TPO tree anywhere in Thanet) can attract a fine of up to £20,000 per tree on summary conviction, with unlimited fines available on indictment. That is not a rhetorical maximum; TDC has prosecuted for tree offences.
The Victorian and Edwardian villa gardens in Broadstairs — particularly the Stone Bay and Pierremont belts — regularly contain mature holm oaks, yews and holly standards grown up inside working hedge lines. They look like part of the hedge. They are not. They are individual trees over the 75mm threshold, and reducing one as part of a hedge cut without filing a notice is technically an offence.
What's exempt
Plenty, actually. The exemption list is what makes most routine hedge cutting in Broadstairs fall outside the rule.
- Hedging-species cutting. Trimming a privet, laurel, Escallonia, Griselinia, Olearia, Euonymus or Elaeagnus hedge — none of that needs a notice, even in a conservation area, even if the hedge is old and well-established. The rule targets trees; hedging species in their working role as a hedge are exempt.
- Stems under 75mm. Young hedges, formative cuts, anything where the largest individual stem is below the threshold.
- Dead, dying or dangerous trees. You can take down a dead tree without notice. Urgent work on a dangerous one is exempt, though the council expects to be told within five days.
- Fruit trees cultivated for fruit. A working apple tree is exempt while it stops being a productive fruit tree.
What this means in practice for most Broadstairs hedge jobs: the notice does not apply. A routine Escallonia, Griselinia, laurel, privet or Leylandii hedge cut in a conservation area is normally exempt. The notice catches the awkward cases — the holm oak grown up within an old field hedge on Reading Street, the mature yew at the corner of a Pierremont villa garden, the holly standard in the middle of an Edwardian Stone Bay boundary hedge.
The hidden traps
Three things catch people out.
Mature standards inside a hedge line. A lot of Broadstairs hedges — particularly on the Victorian and Edwardian villa belt from Stone Bay north, and around Pierremont — have one or two big trees grown up inside them. Holm oak, yew, holly, occasionally an old sycamore. They look like part of the hedge but they're individual trees over the 75mm threshold. Reduce one of those as part of a hedge cut without filing a notice, and it is technically an offence. Fine: up to £20,000 per tree.
TPO trees mixed into hedges. Separate to conservation areas, individual TPOs can apply anywhere in Thanet. They show on the same council mapping layer. If a hedge line includes a TPO tree, that tree needs full consent (not just a notice), and the rest of the hedge work has to be planned around it.
Listed building curtilage. If the property is listed (Grade I, II* or II), the garden walls, gate piers and structural features within the curtilage are also listed by default. Replacing a hedge with a wall — or removing a wall to plant a hedge — needs Listed Building Consent. Some of Pierremont's finer villa stock is in this category. Trimming the hedge: no consent needed. Changing the boundary type: full consent.
The High Hedges route
Different rule, worth mentioning. Under Part 8 of the Anti-Social Behaviour Act 2003, if an evergreen or semi-evergreen hedge over 2 metres is causing a neighbour a reasonable loss of light or amenity — and they have tried and failed to resolve it with you first — they can lodge a formal complaint with Thanet District Council. TDC's fee for this complaint is £650 (2026). If TDC finds in the complainant's favour, they can order a specific reduction with a compliance deadline. Broadstairs' four-floor Gladstone Road terraces and the Stone Bay clifftop villas throw up genuine High Hedges cases — a 6m mature laurel or Leylandii on those plots is not unusual.
How I handle it
Before I quote any conservation-area job, I check three things:
- The Thanet DC mapping layer — is the property inside one of the three CA polygons, and are there any individual TPOs on the plot?
- The hedge line — any stems over 75mm at chest height that would need a notice?
- The property — listed building? Any wall/gate/railing work that would trigger LBC?
If a notice is needed, I file it on your behalf. The s.211 form is a single page; I attach a description of the work, a sketch of the hedge, and my contractor details. Six weeks later, the work goes ahead. There is no fee. If a TPO consent is needed, that is a longer process (eight weeks, fee variable depending on what you're applying for); I'll flag it in the quote so you can decide whether to proceed.
Not sure if your address is in a CA?
Send your postcode to hello@broadstairshedges.co.uk or call 07763 100 477. I'll check the TDC layer and tell you whether the notice applies before you commit to anything. No charge for the check.
