Tree Preservation Orders: What They Mean for Your Building Project

Buying a plot with mature trees on it can feel like a real win; those established oaks and beeches give a site instant character and value. What many landowners in Surrey do not realise until later is that some of those trees may be legally protected, and that cutting, pruning or even root-disturbing them without permission can land you with a heavy fine. A Tree Preservation Order is the mechanism councils use to protect trees they consider important, and understanding whether one applies to your site is one of the first things you should check before you plan any building work.

We speak to developers and homeowners all the time who assumed the trees on their land were theirs to manage as they saw fit, only to discover a protection order halfway through a project. That is exactly the sort of delay, expense and stress a little early knowledge can spare you. In this guide we explain what orders relating to Tree Preservation actually are, how to find out if one covers your site, what you can and cannot do, and how to keep your project moving without falling foul of the law.

What A Tree Preservation Order Actually Is

A TPO, is a legal order made by a local planning authority to protect a specific tree, a group of trees, or an entire woodland. Once an order is in place, it becomes an offence to cut down, top, lop, uproot, wilfully damage or wilfully destroy the protected trees without the council’s written consent. The protection applies regardless of who owns the land, so inheriting or buying a site does not wipe the order clean.

Councils make these orders when they consider a tree to be of value to the public, whether for its visual contribution to the area, its rarity, its age, or its importance to local wildlife. A single striking oak on a prominent corner might be protected, or a council might place a blanket order across a whole belt of woodland. The common thread is that someone at the authority has judged those trees worth keeping for the benefit of the wider community, not just the person who happens to own them.

How To Find Out If Your Trees Are Protected

The good news is that this information is a matter of public record, so you do not have to guess. Every local planning authority keeps a register of the Tree Preservation Orders in its area, and most now make this searchable online. Before you commit to a purchase or finalise a design, it is well worth checking directly with the council that covers your site.

There are a few reliable ways to confirm the status of the trees on your land:

• The local authority TPO register: the definitive source, held by the council’s planning or tree officer, showing every order and the trees it covers.
• A local land charges search: carried out as part of the conveyancing process when you buy, which should flag any orders affecting the property.
• Conservation area status: separate from a TPO but just as important, because most trees in a conservation area enjoy similar protection even without a specific order.
• A professional arboricultural consultant: who can check the records for you, interpret what they mean for your plans, and spot protections a general search might miss.

It is a common and costly assumption that no order on the register means no restrictions. Trees within a conservation area are protected by default, and a council can also serve a new order at short notice if it believes trees are under threat, sometimes in direct response to a planning application.

What You Can And Cannot Do To A Protected Tree

Once a Tree Preservation Order is in force, the default position is simple: you must apply for consent before carrying out any work to the tree. That includes felling, but it also covers pruning, crown reduction, cutting back branches that overhang your property, and any work that disturbs the root system. Even seemingly minor jobs need permission, and the responsibility to seek it sits with the landowner.

There are limited exceptions. Work to a tree that is genuinely dead, or that presents an immediate and serious risk to people or property, may be carried out without prior consent, but you are usually required to give the council notice and to keep evidence of the tree’s condition. The bar for this is high; a tree being inconvenient, dropping leaves, or blocking light does not qualify. If in doubt, the safe course is always to apply and let the tree officer decide.

The penalties for getting this wrong are not trivial. Unauthorised work that destroys a protected tree can lead to a substantial fine, and courts take into account any financial gain the offender made, for example by clearing a plot to build on it. On top of the fine, you may be required to plant a replacement tree, which then becomes protected in its own right.

How Tree Preservation Orders Affect A Building Project

For anyone developing a site, it is not just a legal box to tick; it can genuinely shape what you are able to build. A protected tree near your proposed footprint brings a root protection area with it, a zone around the trunk where excavation, foundations and hard surfacing are restricted. That can push a building line back, rule out a particular driveway route, or force a rethink of drainage runs.

This is why we always encourage clients to establish the tree position early, ideally before the architect finalises a layout. It is far easier and cheaper to design around a protected tree from the outset than to redraw plans after a planning officer raises an objection. A well-prepared application that clearly shows how protected trees will be retained and safeguarded is also far more likely to sail through committee than one that appears to ignore them.

Where a protected tree genuinely cannot be retained, removal is not automatically off the table, but it demands a strong, evidenced case and, almost always, a commitment to replacement planting. The council will weigh the value of the tree against the merits of the development, and a credible arboricultural report is what puts that argument on a professional footing.

Common Mistakes Landowners Make With Protected Trees

Most of the trouble we are called in to untangle comes from a handful of avoidable misunderstandings. Knowing them in advance keeps your project on the right side of the law.

• Assuming ownership means control: owning the land does not give you the right to fell a protected tree; the order stays with the tree, not the title.
• Confusing conservation areas with TPOs: trees in a conservation area are protected even without a specific order, and you must give the council six weeks’ notice before most work.
• Treating pruning as exempt: lopping, topping and cutting back all count as works requiring consent, not just felling.
• Relying on a contractor’s word: a tree surgeon quoting for the job is not the same as the council granting permission; the legal duty is yours.
• Leaving the check too late: discovering an order after work has started, or after exchange of contracts, is when a straightforward project becomes an expensive one.

Frequently Asked Questions About Tree Preservation Orders

How do I know if a tree has a TPO on it?

Contact the local planning authority for your area and ask to check the TPO register, which is public. A conveyancing search should also reveal any order when you buy, and an arboricultural consultant can confirm the position and explain what it means for your plans.

Can I remove a protected tree if it is dangerous?

Work to a tree that is dead or poses an immediate serious risk can sometimes be carried out without prior consent, but you should notify the council and keep photographic evidence of its condition. The threshold is high, so seek advice before acting unless there is a genuine emergency.

What happens if I cut down a protected tree by mistake?

Ignorance is not generally a defence. Unauthorised removal can result in a significant fine and an obligation to plant a replacement, so it is always worth checking a tree’s status before any work begins.

Do Tree Preservation Orders expire?

No. An order remains in force until the council formally revokes it, which is rare. It continues to apply through changes of ownership and over many years, so an old order is just as binding as a new one.

Can I still build if there is a protected tree on my site?

Very often, yes. The key is to design around the tree and its root protection area, and to demonstrate in your application how it will be retained and safeguarded. A clear arboricultural report is central to making that case to the council.

Your Pre-Project Tree Protection Checklist

• Check the register: confirm with the local authority whether any Tree Preservation Order covers your site.
• Confirm conservation status: establish whether the property sits within a conservation area, which brings its own protections.
• Map the trees early: get protected trees and their root protection areas onto the plan before the design is fixed.
• Apply for consent: never assume; seek written permission before any felling, pruning or root disturbance.
• Commission a report: back your planning application with a professional arboricultural assessment.
