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. It is one of the few corners of planning law with genuine criminal penalties — and one of the most widely misunderstood.
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 a tree contributes to the look and character of an area and is worth keeping. It does not have to be rare or ancient; visual and public value is enough. A perfectly ordinary street lime can be protected precisely because losing it would harm the street scene.
What a TPO can protect
An order can cover:
- an individual tree;
- a group of trees (protected as a group, so the value is collective);
- an area of trees (a snapshot of trees present when the order was made); or
- a whole woodland (which protects trees within the defined area, including natural regeneration).
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 is "damage" for these purposes, even if the trunk is never touched. This is exactly why development near a protected tree needs a proper BS5837 tree survey and, where the tree is affected, an arboricultural impact assessment.
How consent works
If you want to carry out works to a protected tree, you apply for consent — a process entirely separate from any planning application.
| Step | Detail |
|---|---|
| How to apply | A standard application form to the council, describing the tree, the proposed works and the reasons |
| Fee | No fee for a TPO consent application |
| Decision period | The council has eight weeks from valid receipt to decide |
| Validity of consent | Once granted, generally valid for two years |
| Appeal route | Refusal, unwelcome 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 council will often consult its tree officer, and may grant consent subject to conditions — for example requiring works to a defined specification, or a replacement planting. Vague applications ("crown reduce the oak") tend to be refused or heavily conditioned; a clear specification from a qualified arboriculturist fares far better.
The exemptions people get wrong
The regime has exemptions, and misreading them is how honest people end up prosecuted. Broadly, you do not need consent for:
- Dead trees — but you must give the council five working days' prior notice (except in a genuine emergency where danger must be removed immediately).
- Urgent works to remove an immediate danger — narrowly interpreted; keep photographic and, ideally, arboricultural evidence taken before the work.
- Works to prevent or abate a legal nuisance — a genuine actionable nuisance, not mere inconvenience like leaf fall.
- Works to comply with an Act of Parliament.
- Works needed to implement a full planning permission — specific and limited to what the permission actually requires, not a blanket right to clear the site.
The single biggest trap: the 2012 Regulations replaced the old "dead, dying or dangerous" test with "dead" plus urgent works to remove danger. A merely "dying" or "dangerous-looking" tree is no longer automatically exempt. Anyone still quoting the old three-word phrase — and the contractors who confidently repeat it — are the ones who get caught. If in doubt, notify the council or apply for consent; the paperwork is far cheaper than a prosecution.
A worked example: the driveway that killed a protected oak
A homeowner lays a new block-paved driveway, excavating 300mm across the front garden. A protected oak stands 5m away. Nobody cut the tree — but the excavation severed structural roots inside the RPA, and eighteen months later the crown thins and the tree declines beyond recovery. That is wilful damage to a protected tree: an offence, even though no branch was ever pruned. Had the owner checked the register, commissioned a survey and used a no-dig build-up over the roots, the driveway and the tree could both have survived. The lesson: with a TPO, what you do to the ground matters as much as what you do to the tree.
Penalties for breaching a TPO
Unauthorised work to a protected tree is a criminal offence, and the penalties are real:
- Destroying a protected tree — 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, such as unauthorised pruning that does not destroy the tree — fines up to £2,500.
- Courts specifically weigh any financial benefit the offender gained — a cleared plot worth more for development is an aggravating factor, not a defence.
- You can be placed under a duty to plant a replacement tree in the same place, and that replacement automatically becomes protected by the original order.
Ignorance is not a defence, and nor is relying on a contractor's assurance. Liability can fall on the landowner as well as whoever wielded the saw.
Conservation areas: the separate rule
Not every protected tree has a TPO. Trees in a conservation area that are not already covered by a TPO are protected differently: you must give the council a section 211 notice six weeks before carrying out most works. The key differences from a TPO:
| TPO consent | Conservation-area s.211 notice | |
|---|---|---|
| What you file | An application for consent | A notice of intent |
| Council response | Grants, refuses or conditions it | Either makes a TPO, or lets the period lapse |
| Can it be "refused"? | Yes | No — it cannot be refused or conditioned |
| Timescale | 8-week decision | 6-week waiting period |
| If nothing happens | You need the consent | You may proceed, within two years |
Those six weeks give the council a window to make a TPO if it wants to keep the tree. It is protection by notice-and-wait rather than application-and-decision — but the practical effect is the same, so treat conservation-area trees with the same caution as any protected tree. (A small-size threshold applies to which trees the regime catches; if you are unsure whether a tree is big enough to be covered, notify anyway.)
Why it matters before you buy or build
A TPO stays with the tree regardless of ownership, so it passes to you when you buy the land. "I didn't know it had a TPO" is a weak defence. Before any tree work — or any purchase where trees matter to your plans — a quick check is worth the few minutes: use our TPO checker to find the right council register by postcode.
Requirements are set locally — check the right council
Although TPOs sit within a national legal framework, they are made and enforced by individual local planning authorities, and this is where applicants go wrong. The register you must check is the one held by the council for the tree's location, which is not always the council where you live. Conservation-area boundaries, the density of TPOs, and how actively a tree officer polices them all vary enormously between authorities — a heavily-treed borough may protect thousands of trees, while a neighbouring rural district relies more on conservation-area cover.
Because it is set and policed locally, the only reliable answer to "is this tree protected, and how strictly?" comes from the specific council. Authorities such as Leeds, Lambeth, Manchester and Bristol each publish their own TPO registers and conservation-area maps, and each has its own enforcement culture. PlanWatch tracks live tree-related planning activity per council, so you can see how your authority actually handles TPO consents and s.211 notices in real cases — start at the tree-surveys hub and check your area.

The bottom line
A TPO is real criminal law wrapped around a tree. It protects the whole living thing — trunk, branches and roots — and it does not care whether you meant to cause harm. If you are planning development near a protected tree, you will almost certainly need a BS5837 tree survey, an arboricultural impact assessment and, during the build, a tree protection plan.
