Damaging a protected tree: the offences, fines and liability

Cutting down a tree protected by a Tree Preservation Order without consent is a criminal offence carrying an unlimited fine, and the court is required to take account of any financial benefit the offender gained. For a landlord who removed a mature oak because it was shading a rear extension, that benefit is the uplift in the value of the scheme, and it can be a large number. The same protection applies to trees in a conservation area, where a six-week notice replaces a formal application but the offence provisions bite in the same way.

Liability is not limited to the owner. A contractor who swings the saw and an agent who instructed the work can both be prosecuted.

The offences created by the tree preservation regime

Two offences sit in section 210 of the Town and Country Planning Act 1990, and the difference between them decides how serious the day becomes.

The first, under section 210(1), covers cutting down, uprooting or wilfully destroying a protected tree, and wilfully damaging, topping or lopping it in a manner likely to destroy it. It also catches anyone who causes or permits those acts. This offence is triable either way, so it can be heard in the Crown Court, and there is no six-month time limit on bringing proceedings.

The second, under section 210(4), covers any other contravention of an order, which in practice means pruning or reduction work carried out without consent that falls short of destroying the tree. It is a summary offence with a fine capped at level 4 on the standard scale.

For trees in a conservation area, section 211 requires six weeks' written notice to the local planning authority before works to a tree above 75 mm in diameter measured at 1.5 m, or above 100 mm where the work is thinning. Carrying out the work without that notice attracts the same offence provisions.

Destruction, damage and what counts as either

"Destroys" does not require the tree to be felled. A tree rendered incapable of continued growth in its existing form is destroyed, and severe root severance during excavation can achieve that without a single branch being cut.

That matters on construction sites. Trenching for a soakaway across a root protection area, storing spoil over the roots, or compacting the ground with a tracked machine can all kill a tree over the following two seasons. Prosecutions have followed works of that kind, and a defence that nobody intended to harm the tree runs into the word "wilfully", which goes to the act rather than to the outcome.

Damage short of destruction is a section 210(4) matter. A crown reduction of a third, carried out on a TPO tree without consent, is the classic example.

The exemptions in the Town and Country Planning (Tree Preservation) (England) Regulations 2012 are narrower than most people believe. Dead trees can be removed with five days' notice given afterwards. Works to remove an immediate risk of serious harm are permitted with notice as soon as practicable. "Dying" and "dangerous" as free-standing categories went in 2012. Relying on a verbal assurance from a tree surgeon that a tree was "unsafe" is not a defence unless the risk was immediate and serious.

Penalties on conviction and how they are assessed

Section 210(3) directs the court, in determining the fine, to have regard to any financial benefit that has accrued or appears likely to accrue as a consequence of the offence. That provision is the reason fines in development cases are so much higher than fines for a domestic homeowner who wanted more light in the kitchen.

There is a separate consequence that outlasts the fine. Section 206 imposes a duty on the landowner to plant a replacement tree of appropriate size and species at the same place as soon as reasonably possible. The authority enforces that duty through a tree replacement notice under section 207, which runs with the land and is appealable to the Secretary of State. A purchaser can inherit it.

Confiscation proceedings under the Proceeds of Crime Act 2002 are available where the offence produced a quantifiable benefit. They are not routine, and the possibility is real enough to mention to a client who is weighing the fine against the value of an extra plot.

Liability of owner, agent and contractor

The words "causes or permits" in section 210(1) spread liability across the chain.

An owner who instructs the removal is liable. A managing agent who arranges the contractor without checking for protection is liable. The tree contractor is liable, and contractors are prosecuted regularly, because a professional in the trade is expected to check the status of a tree before starting.

Three practical consequences follow. Written instructions matter, because the paper trail decides who carries the risk. Contractor terms should require the contractor to satisfy itself of the tree's status. And insurance rarely responds to a criminal fine, whatever the policy says about legal expenses.

Investigation, evidence and prosecution decisions

Councils investigate through their tree officers. The evidence is more durable than people assume: dated aerial imagery, street-level imagery, previous survey records, the stump itself, and increasingly a neighbour's photographs with metadata.

Stump analysis establishes whether a tree was alive at the point of felling, which disposes of the "it was dead" defence in most cases. Ring counts and decay assessment are routine.

Authorities do not prosecute every breach. The usual factors are the value of the tree in amenity terms, whether the act was deliberate, whether a financial benefit followed, and whether the offender has previous. A first-time domestic breach of a small tree often ends with a replacement notice. A development site that lost a category A tree does not.

Reducing risk on a live construction site

Six steps, in order, and none of them takes long.

1. Check protection status before contracts are signed. Search the council's mapping and the national planning data service for TPOs and conservation area boundaries, and ask the tree officer in writing if it is unclear.
2. Commission a tree survey to BS 5837:2012 with a tree constraints plan, so root protection areas appear on the layout drawing.
3. Get consent in writing for any works, and read the conditions on it. Consent for a reduction is not consent for a fell.
4. Install protective fencing to the arboricultural method statement before any plant arrives, and photograph it in place with a date.
5. Include tree protection in the site induction, and repeat it whenever a new subcontractor mobilises. A groundworker who has never heard of a root protection area will dig where the setting-out says to dig.
6. Where excavation inside a root protection area is unavoidable, agree the method with the tree officer first and record it in the Construction Management Plan.

Illustrative example: a conversion of a former office to flats where a drainage run was moved 2 m to avoid a protected beech, at a cost of a day's work and a revised drawing. The alternative was a felled beech, a replacement notice and a prosecution file. This example is illustrative.

Trees survive development when someone owns the problem before the machines arrive. After that, everything is damage limitation.
