TPOs and Conservation Areas: What Tree Surgeons Must Check

You quote a job, turn up with the chipper, and start dropping limbs. Then a neighbour mentions the tree is "protected". Now you could be looking at a prosecution and a fine that wipes out a year's profit. Getting the legal checks right before the saw comes out is the difference between a clean job and a very expensive mistake.

This guide covers what Tree Preservation Orders (TPOs) and conservation area rules mean for tree surgeons in England and Wales, who carries the risk, and how to build the checks into your quoting process so nothing slips through.

What a Tree Preservation Order Actually Is

A Tree Preservation Order is a legal protection made by a local planning authority on a specific tree, group of trees or woodland. Once a TPO is in place it is an offence to cut down, top, lop, uproot, wilfully damage or wilfully destroy that tree without the authority's written consent.

A TPO can cover:

• A single named tree
• A group or line of trees
• An area defined on a plan
• A whole woodland

The protection does not care about the species, the size or whether the tree looks healthy. If there's an order on it, you need consent.

Tip: TPOs and conservation areas are devolved matters. The detail differs in Scotland and Northern Ireland, so always check the rules that apply where the job is, not a general summary.

Conservation Areas: A Separate Set of Rules

Conservation areas work differently from TPOs and it's easy to confuse the two. In a conservation area, most trees above a certain trunk size are protected even without an individual order.

The key point for your day-to-day work: before doing tree work in a conservation area you usually have to give the local planning authority advance written notice — commonly six weeks — so they can decide whether to make a TPO. You can't just crack on.

Because the size thresholds, exemptions and notice periods can change and vary by authority, treat the council's current guidance as the source of truth rather than anything you half-remember from a previous job.

How to Check Before You Quote

Never rely on what the customer tells you. Homeowners often genuinely don't know, and "the last bloke did it and nothing happened" is not a defence.

Run these checks for every tree job:

1. Ask the local planning authority. Most councils let you search for TPOs and conservation area boundaries online, or you can ring the tree officer.
2. Check the address, not just the postcode. A TPO can apply to one garden and not the one next door.
3. Look at the whole site. A group or woodland TPO can catch trees a customer doesn't think of as "the" protected tree.
4. Get it in writing. If you apply for consent or submit a conservation area notice, keep the paperwork.

Building this into your routine means it happens every time, not just when something feels off. A morning routine that keeps jobs on track is the perfect place to lock in a "TPO checked?" step before any crew rolls out.

Applying for Consent (and How Long It Takes)

Where a tree is covered by a TPO, you apply to the local planning authority for consent to carry out the work. For conservation areas, you submit a notice of intent rather than a full consent application.

A rough guide to the process:

• TPO consent decisions commonly take around eight weeks, though it varies by authority and workload.
• Conservation area notices typically run on a shorter notice period before you can proceed.
• A clear application — species, what you propose, and why — tends to move faster than a vague one.

The practical takeaway: these are lead-time decisions, not same-week ones. If a customer wants the work done next Tuesday and the tree is protected, you need to manage that expectation up front. Pricing and timelines should reflect the admin and the wait, which is something to factor in when you quote for a tree job without underselling.

Exemptions — and Why You Shouldn't Lean on Them

There are limited exemptions, the most talked-about being work needed because a tree is dead or presents an urgent and immediate danger. But the bar is high and the burden of proof sits with whoever did the work.

Common traps:

• "Dead" doesn't mean "in poor condition" or "looks rough".
• "Dangerous" usually means immediate risk, not a general concern about future failure.
• Even where an exemption applies, you may still have to give notice and you should keep dated evidence — photos, reports, measurements — proving the condition before work started.

Don't talk yourself into an exemption to save the hassle of an application. If a council disagrees after the fact, you're the one explaining it.

Who Carries the Legal Risk?

This is the part that catches contractors out. The offence of carrying out unauthorised work can fall on the person who does the work, not only the landowner who asked for it.

So even if a customer instructs you, swears the tree isn't protected and signs everything, you can still be prosecuted for the actual cutting. The penalties for unauthorised work on a protected tree can be severe — potentially well beyond the value of the job.

Protect yourself by:

• Making the checks yourself rather than relying on the customer
• Recording your TPO and conservation area enquiry on the job file
• Keeping a written instruction from the customer
• Holding the right tree surgeon insurance and your method statements on record

Good record-keeping is your defence. A job-management system like Gaffer keeps the TPO check, the customer's written go-ahead, site photos and the council reference all attached to the job — so if anyone ever questions a job months later, the evidence is in one place instead of scattered across texts and a clipboard.

Build the Check Into Your Quote, Not as an Afterthought

The cleanest approach is to treat the legal check as part of quoting, not a separate task you might forget. When the protected-tree enquiry is a fixed step before any price goes out, you stop the nightmare scenario of committing to a date and price for work you're not yet allowed to do.

It also looks professional. A customer who hears "I'll confirm there's no TPO before we book this in" trusts you more than the contractor who just turns up swinging. With Gaffer you can capture the check, send a clear quote, then fire off automated booking reminders once consent lands — less admin, fewer slip-ups, and a paper trail that protects you.

FAQs

How do I find out if a tree has a TPO?

Contact the local planning authority for the property's address — most have an online map or a tree officer you can ask. Don't rely on the customer's word; check the specific address, as a TPO can cover one property and not its neighbour.

Can I prune a tree in a conservation area without permission?

Usually you must give the local planning authority advance written notice (commonly six weeks) before carrying out work on protected trees in a conservation area, so they can decide whether to make a TPO. Check the current rules with the council before starting.

What's the penalty for cutting down a protected tree?

Penalties for unauthorised work on a TPO tree can be significant fines, and serious cases can carry heavier sanctions. Because the figures and rules change, confirm the current position with the relevant authority rather than assuming.

Who is liable if a customer tells me to cut a protected tree?

The person who actually carries out the work can be prosecuted, not just the landowner. That's why you should make the TPO and conservation area checks yourself and keep written records, regardless of what the customer claims.
