A Tree Preservation Order (TPO) is a legal order made by a local council that makes it a criminal offence to cut down, top, lop, uproot or wilfully damage a protected tree without written consent — with fines up to £20,000 in the Magistrates' Court, or unlimited in the Crown Court. It is one of the very few areas of planning law that carries genuine criminal penalties, and it is also one of the most widely misunderstood. This guide covers what a TPO actually protects, how to check for one, how to get consent, the exemptions that trip people up, and what happens if you get it wrong.
What a TPO is — and where the power comes from
TPOs are made under Part VIII of the Town and Country Planning Act 1990, with the operational rules set by the Town and Country Planning (Tree Preservation) (England) Regulations 2012 (in force from 6 April 2012). A council makes an order "in the interests of amenity" — broadly, because the tree contributes to the look and character of an area and is worth keeping. Amenity is assessed on visibility, the tree's individual and collective impact, and its wider value (screening, historic or landscape significance).
A TPO can protect four things:
| TPO type | What it covers |
|---|---|
| Individual | A single named tree, mapped as a dot on the order plan. |
| Group | Several trees protected together because their collective effect is what matters. |
| Area | All trees of a defined species/type within a mapped boundary at the date the order was made (a snapshot, not perpetual — younger trees planted later are not automatically caught). |
| Woodland | Every tree within the woodland boundary, including saplings and self-seeded trees that grow up later. |
Once a tree is covered, the order prohibits cutting it down, topping, lopping, uprooting, and any wilful damage or destruction — including cutting roots — without the local planning authority's written consent. That last point catches developers out: severing roots inside a root protection area during construction, or compacting the soil over it, is "damage" for these purposes even if no branch is ever touched.
Scope note: this guide is England-centric. Scotland (under the Town and Country Planning (Scotland) Act 1997), Wales and Northern Ireland run parallel but distinct regimes — see TPOs in Scotland, Wales and Northern Ireland — so always check the rules for the relevant nation.
How to check if a tree has a TPO
There is no single national TPO map. Orders are made and held by each local planning authority, so the first job is to find the right council for the address, then search its register. A full walkthrough lives in our guide on how to check if a tree has a TPO, but the core steps are:
- Identify the local planning authority for the postcode — TPO powers sit with the district, borough, city or unitary council, not the county.
- Search the council's TPO register or online map — most publish one, often as an interactive constraints layer.
- Check conservation-area status too — trees in a conservation area are separately protected even without a TPO (see below).
- Contact the tree officer for a definitive answer on a specific tree; registers can lag reality, and boundaries on a scanned 1970s order map are not always precise.
You can start that process on our TPO checker, which points you to the right council register by postcode and shows the tree-related planning activity PlanWatch is tracking in that area. If you are buying, do this before exchange — our guide to buying a house with a TPO explains why an undiscovered order can wreck an extension plan after completion.
Applying for consent to work on a TPO tree
If you want to carry out works to a protected tree, you apply for consent — a separate process from any planning application, on a dedicated form.
| Element | Detail |
|---|---|
| How | Standard application to the council describing the tree, the specific works and the arboricultural reasons. |
| Decision period | The council has eight weeks from valid receipt to decide. |
| Validity | Consent, once granted, is generally valid for two years. |
| Conditions | The council may grant with conditions — for example a replanting requirement, or a specified pruning specification. |
| Appeals | Refusal, disliked conditions, or non-determination within eight weeks can be appealed to the Secretary of State (Planning Inspectorate) under Regulation 19 of the 2012 Regulations. |
The stronger your arboricultural justification, the more likely consent. A vague "the tree is too big" is easily refused; a report showing decay, a defensible risk rating or a well-argued crown-reduction spec is not. Our guide to pruning or felling a tree with a TPO covers what a tree officer actually wants to see. Where the works arise from a development, the council will expect proper evidence — usually a BS5837 survey and an arboricultural impact assessment — submitted alongside the consent request.
Conservation-area trees: the separate six-week rule
Trees in a conservation area that are not already covered by a TPO get their own protection, and it works differently. Before carrying out most works you must give the council a "section 211 notice" six weeks in advance.
- Those six weeks give the council a window to make a TPO if it wants to keep the tree.
- If the council doesn't object or make an order within the six weeks, you may carry out the notified works within two years of the notice.
- A section 211 notice is not an application for consent — it can't be "refused" or granted with conditions. The council either makes a TPO or lets the period lapse.
The notice threshold is a small stem size (commonly cited as trees over 75 mm in diameter measured at 1.5 m, or 100 mm where thinning to help other trees grow), so genuinely small stems are outside the regime. A conservation-area tree is therefore protected by default, but through a notice-and-wait mechanism rather than an application-and-decision one. Our guide on TPO vs conservation-area trees unpacks the two side by side. Either way, if the tree affects a development you'll still likely need a BS5837 survey.
Exemptions — the part homeowners get wrong
Both the TPO and conservation-area regimes carry exemptions, and getting them wrong is how honest people end up prosecuted. Broadly, you don't need consent for:
| Exemption | The catch |
|---|---|
| Dead trees | You must still give the council five working days' prior notice (except a genuine emergency), and the tree must actually be dead — not just in poor condition. |
| Urgent works to remove an immediate danger | Narrowly interpreted; only the works needed to remove the danger, not a full fell. Photograph and document everything before cutting. |
| Preventing or abating a legal nuisance | Must be an actual nuisance in law, not mere inconvenience or leaf-fall; only the works reasonably needed to abate it. |
| Complying with an Act of Parliament | E.g. a statutory obligation on a highway or utility. |
| Implementing a full planning permission | Applies to a full permission (not outline), and only for works its implementation actually necessitates. |
The single biggest trap: the 2012 Regulations replaced the old "dead, dying or dangerous" test with "dead" plus urgent works to remove danger. A "dying" or merely "dangerous-looking" tree is no longer automatically exempt. Homeowners who still quote the old three-word phrase — and the contractors who repeat it — are the ones who get caught. If in any doubt, notify or apply; the cost of a rejected notice is nothing next to a prosecution.
Penalties for breaching a TPO
Unauthorised work to a protected tree is a criminal offence, and the penalties are real. Our dedicated guide on TPO fines and penalties goes deeper, but in summary:
- Destroying a protected tree (or works likely to destroy it) — a fine of up to £20,000 in the Magistrates' Court, and an unlimited fine if the case is committed to the Crown Court.
- Lesser breaches (e.g. unauthorised pruning that doesn't destroy the tree) — fines up to £2,500.
- Courts specifically weigh any financial benefit the offender gained — for example, a plot worth far more cleared for development. This is designed to stop the fine being treated as a cost of doing business.
- You can also be placed under a duty to plant a replacement tree of appropriate size in the same place — and that replacement is itself automatically protected by the original order.
Because liability is treated strictly in practice, "I didn't know it had a TPO" is a weak defence — which is exactly why a TPO check before any tree work, or any purchase, is worth the five minutes.
Worked example: the cleared plot
A developer buys a garden plot with a mature oak near the rear boundary, intending a two-unit scheme. Rather than commission a tree survey, they have the oak felled "to open the site up" before applying. The oak carried an individual TPO the seller never mentioned. The council prosecutes; the fine reflects the uplift in the plot's development value once the constraint was removed, a replacement-tree order is imposed, and the redesign the oak would have forced now happens anyway — around a stump. Every part of that outcome was avoidable with a £0 register check.
TPOs and development: how it fits together
For anyone building, three separate sources of tree-related obligation run in parallel, and they must not be confused:
- Local validation — the council won't register a planning application that lacks the arboricultural documents its checklist demands where trees are affected. Miss them and the application is returned unvalidated; see tree survey rejected at validation.
- Planning conditions — permission often comes with pre-commencement conditions requiring a final tree protection plan and arboricultural method statement, which must be discharged in writing before works start.
- Statutory tree protection — TPO and conservation-area rules, enforced by criminal law, sit on top of all of it.
A single tree can trigger all three at once. Crucially, the BS5837 planning documents and the TPO consent regime are not substitutes: an approved arboricultural impact assessment does not give you licence to cut a TPO tree, and TPO consent does not validate your planning application.
Requirements are set locally — check your council
This is the part national guides gloss over: the practical bar is set by your specific local planning authority, not by a single UK rulebook. TPO density, conservation-area coverage, how quickly a tree officer will slap a new order on a threatened tree, and exactly which arboricultural documents a validation checklist demands all vary council to council. Two identical extensions either side of a borough boundary can face very different tree scrutiny.
PlanWatch tracks live tree-related planning activity per council, so you can see how active a given authority is — new TPOs, conservation-area works notices, applications turning on retained trees — before you buy or apply. Compare local pages such as Leeds, Manchester, Lambeth, Bristol and Nottingham, or start from the tree-surveys hub and search your own postcode. Whatever a national article says, the tree officer for your address has the final word — confirm status and validation requirements with them.
Next steps
If you're at the start of a project, read do I need a tree survey for planning and check what a survey costs. If a protected tree is already in play, use the TPO checker to confirm status, then commission a suitably qualified arboriculturist. Then let PlanWatch watch live tree and planning activity around any address — including applications that affect protected trees near you.
