How to apply for permission to prune trees in a Dover conservation area, step by step
People search for a "conservation area permit" for tree work in Dover, so that is what this guide is about. One thing to know before you start: in England the paperwork is not a permit and not an application. It is a notice of intended works, known as a section 211 notice (Town and Country Planning Act 1990). You tell Dover District Council what you plan to do, it has six weeks to react, and there is no fee. The council cannot refuse it or attach conditions, but it can answer by making a Tree Preservation Order (TPO), and that is the risk worth planning around.
This is the application walkthrough, built around the questions Dover owners actually ask. The rules themselves are explained in our section 211 guide for Dover, so this page sticks to doing it. Every council link below was checked against the council's own pages on 30 September 2026.
The short version
Check your address on the council's map. Measure any trunk in or beside the hedge (over 75mm across at 1.5m above the ground counts as a tree). If one qualifies and is not already under a TPO, email the works you want, the tree's location and your contact details to the council at least six weeks before the work. Wait. If you hear nothing, you have two years from the date of the notice to do exactly what you described. A hedge you trim as a hedge does not need any of this.
Step 1. Is my Dover address inside a conservation area?
Search your postcode or street name on the council's conservation area map; Dover District Council lists 57 conservation areas across the district, and if your property sits inside a boundary, the tree rules apply to your garden.
In Dover itself the council's own map layer names these areas: Town Centre, Dour Street, Charlton Green, London Road, Dover College, Dover Castle, Waterloo Crescent and Western Heights. The council's conservation areas page explains the designation and links the appraisals. Boundaries follow historic layouts, not postcodes, so two houses on the same road can fall either side of a line. Do not assume from the street name; look at the map, zoom to your plot, and screenshot it for your file.
The council's map notes that it is for viewing only and should not be used as evidence in planning applications. If your plot sits close to an edge, email the council's tree team (the address is in step 5) and ask them to confirm in writing.
Step 2. Is the plant in my hedge actually a tree?
It is a tree for these rules if it has a trunk more than 75mm across, measured over the bark at 1.5m above the ground; a hedge you keep clipped as a hedge is normally not treated as a tree.
The government guidance says the rules cover "anything that may ordinarily be termed a tree", which would not normally include shrubs but can include trees standing in a hedge, or an old hedge that has grown into a line of trees. In a Dover garden that usually means a hornbeam, beech, holly, ash or sycamore that has been allowed to rise through the hedge, or a leylandii left to run up to a single stout trunk. It applies to any species, evergreen or deciduous, native or not.
How to measure it. Hold a tape measure round the trunk at 1.5m up (about chest height) and divide the distance round by 3.14. Worked example: you measure 26cm round a hornbeam standing in your boundary hedge. 26 divided by 3.14 is about 8.3cm, so 83mm across. That is over 75mm, so it is a tree for these rules. A trunk of 22cm round comes out at about 70mm and is under the line. The threshold works out at about 23.6cm round.
Two wrinkles. If the tree has more than one stem at 1.5m, each stem is measured, and if any one of them is over 75mm the exemption is lost. And the council's own page words the threshold as trees "less than 75mm" needing no notice, while the national guidance says "does not exceed 75mm". A trunk sitting right on the line is a phone call to the council, not a guess.
Which trees in a Dover conservation area need notice, and which do not?
Any tree with a trunk over 75mm across at 1.5m needs six weeks' notice before you cut down, uproot, top, lop, wilfully damage or destroy it; smaller stems, dead or dangerous trees and clipped hedge plants are treated differently. Here is the scan-friendly version.
| What you are dealing with | Notice to the council? | Detail |
|---|---|---|
| Tree trunk over 75mm across at 1.5m (any species) | Yes, 6 weeks before | Applies to hornbeam, beech, holly, ash, sycamore, leylandii and every other species, evergreen or deciduous. |
| Trunk 75mm or under at 1.5m | No | Unless it has several stems and any one of them is over 75mm. Check any TPO first. |
| Tree of up to 100mm, cut down or uprooted only to give other trees room (thinning) | No | Sole purpose must be improving the growth of the others. |
| Hedge plants clipped as a hedge (privet, laurel, yew, box, hornbeam kept to hedge shape) | No | Not "trees". Wildlife law on nests still applies from 1 March to 31 August. |
| Fruit tree cultivated for fruit | Generally no | The council lists fruit trees cultivated for fruit production as exempt; national guidance ties pruning to good horticultural practice. |
| Dead tree | Five working days' written notice | GOV.UK says five working days' written notice before the work; the council asks for it by email, except in an emergency. |
| Immediately dangerous tree | Notice as soon as practicable | Work only what removes the risk. You may have to show it was dangerous, so photograph it. |
| Tree already under a TPO | Different route | A TPO overrides the conservation area rules and needs a formal application for consent. |
Works that trigger notice are cutting down, uprooting, topping, lopping, and wilfully damaging or destroying a tree. Removing live branches, including lifting a low crown, is lopping, so treat it as needing notice; the guidance exempts dead branches on a living tree. Other narrow exceptions exist (work the council itself carries out, work needed to build something with planning permission already granted, and tree work carried out under a Forestry Commission licence), and the guidance is linked at the end. A hedge is not a tree, but there is a separate regime for important countryside hedgerows: the council's tree page points to the national hedgerow guidance if a field hedge is your question rather than a garden one.
Step 3. Does the tree already have a Tree Preservation Order?
Check the tree on the council's TPO map; if it has an Order, you need formal consent instead of a section 211 notice, because a TPO overrides the conservation area rules.
The council says it has more than 600 TPOs across the district. For a TPO tree it wants a formal application, and the Planning Portal's tree works page covers that route as well as the conservation area notice. Trees can also be protected by conditions attached to a planning permission (on newer developments, for up to five years), which you can check by searching the address in the council's planning application search. Five minutes on the maps beats six weeks waiting for the wrong document.
Step 4. What do I write in a section 211 notice for a Dover tree?
The law asks for a description of the work, enough detail to identify each tree, and the date; a plan is not compulsory but helps. The guidance adds that one notice can cover several trees and several operations, as long as it is clear which work applies to which tree. Here is a realistic example for a Dover garden hedge (square brackets are yours to fill in):
Example notice (email body)
Subject: Section 211 notice, trees at [house number and street], Dover CT16 [postcode], Dover Town Centre conservation area
I give notice under section 211 of the Town and Country Planning Act 1990 of my intention to carry out the following work on [date].
Tree 1: hornbeam standing in the hedge on the rear (east) boundary, third from the garden gate, marked A on the attached sketch. Girth 26cm at 1.5m (about 83mm across). Work: reduce the crown by up to 1.5m in height and up to 1m in spread, cutting back to suitable growth points, leaving the tree in its natural shape. Reason: it has outgrown the boundary and is shading the kitchen window.
Tree 2: holly in the same hedge, marked B. Girth 30cm at 1.5m. Work: lift the lower crown to 2.5m by removing branches up to 50mm across. Reason: to clear the path.
Photographs and a sketch are attached. Owner and contact: [name, address, phone, email]. Contractor: [name and phone]. Date sent: [date].
Be specific about how much you want off. "Reduce by up to 1.5m" tells the tree officer what to check later; "prune as needed" invites a query. If you are not sure what work a tree can take, ask before you write it down, because the notice fixes what you may do for the next two years.
Step 5. How do I send the notice to Dover District Council?
The council's own tree page says to let it know by emailing tree.enquiries@dover.gov.uk, and you can alternatively use the online notification route on the Planning Portal.
Email is the route Dover District Council names on its tree protection page. Send the notice text, your sketch and photographs as attachments, and keep the sent message: the date on it is the date of your notice. The Planning Portal offers an online "Notification of Proposed Works to Trees in Conservation Areas" that reaches the same council. The council has also published a paper notification form (PDF) you can use as a checklist, although the law does not require any particular form. There is no fee for the notice.
Ask for an acknowledgement. A notice should be acknowledged, and the council may write back if it is too vague, in which case it is better to resubmit than to argue.
Step 6. What happens during the six weeks?
The council can make a Tree Preservation Order, tell you the work can go ahead, or say nothing and let the six weeks run out; it cannot refuse the notice or attach conditions.
If it makes a TPO, the tree is protected and you would then need to apply for formal consent for the work, and you can apply at any time. If it tells you the work can go ahead, you do not have to wait out the six weeks. If it says nothing, the notice period ends and you may do the work within two years of the date of the notice. The council decides mainly on the tree's amenity value and its contribution to the character of the conservation area, so a healthy, visible, mature tree is more likely to attract an Order than a scrappy one behind a shed.
Do not start early unless the council has said in writing that you can. Six weeks is six weeks from the date of the notice.
Step 7. What do I do once the six weeks are up?
Do the work described in the notice, and only that, within two years of the notice date. Keep the sent email, the acknowledgement and your photographs together, because the council keeps a public register and can compare what you said with what was done. Use an insured contractor who will read the notice first, since the guidance is clear that anyone who carries out or arranges the work can be caught, not just the owner. Ask them to work to good arboricultural practice, and if you need to find a qualified arborist the Arboricultural Association directory is a starting point.
Can I prune a tree during the bird nesting season once my notice has run?
Only if you first check for active nests. A section 211 notice does not override the Wildlife and Countryside Act 1981: it is an offence to damage or destroy an active wild bird's nest, and nesting season runs roughly 1 March to 31 August. Time the notice so that the six weeks, and your two-year window, still leave you a September to February slot. Our Dover cutting calendar shows how the months line up.
Step 8. What if the tree is dead or dangerous?
A dead tree needs five days' written notice to the council before work, and an immediately dangerous tree can be dealt with straight away, with written notice as soon as practicable afterwards.
The council's wording is that if a tree is dead or immediately dangerous, permission is not needed, works should be limited to what makes it safe, and notice goes by email to tree.enquiries@dover.gov.uk five days beforehand except in an emergency. It also says the responsibility for showing that a tree was dangerous lies with the owner or the person doing the work, and that photographs and a written opinion from a qualified tree specialist help. "Dangerous" means a present, serious safety risk, not a tree you would rather not have. If the danger is not immediate, use the normal notice. Where a tree is removed because it was dead or dangerous, the landowner has a duty to plant a replacement.
What happens if I do the work without giving notice?
Cutting down, topping, lopping, uprooting or wilfully damaging a tree in a conservation area without a notice is a criminal offence, with a fine of up to £20,000 in the magistrates' court and an unlimited fine in the Crown Court for serious cases.
The same penalties as for breaching a TPO apply. Courts also take account of any financial gain from the offence, and the owner can be required to plant a replacement tree. It is not only the owner at risk: the guidance says that anyone who causes or permits the work, or arranges for someone else to do it, can also face action. It is an easy mistake to avoid with a tape measure and an email.
When should I call in a professional, and what can we do?
Ring us when you are unsure whether a trunk counts, or you want to know how much a hornbeam or leylandii can lose without harm. We will look at your hedge and tell you which trees in it would need notice and which would not, help you word the works so the notice is clear, and carry out the pruning once the notice period has passed. We prune and reduce; the notice itself is yours to sign and send as owner, and we will not start until the six weeks are up.
