TPO Applications & Appeals
Clear, evidence-based support for Tree Preservation Order applications, variations, objections and appeals — structured for planning acceptance.
TPOs protect trees with recognised amenity value. When works are needed for safety, damage prevention or development, evidence must be strong. Focused arboricultural assessment makes applications clearer, more proportionate and more likely to succeed.
POs raise questions — evidence provides direction
Whether you’re facing refusal, unclear restrictions or a request for additional justification, a structured TPO assessment explains what’s reasonable, what’s proportionate and how planners will interpret the proposal. A focused AIA shows how your layout interacts with every relevant tree and sets out reasonable, proportionate solutions.
What is a TPO Application or Appeal?
A TPO Application or Appeal provides the evidence required to:
- justify tree works (pruning, removal or management)
- demonstrate safety or structural concerns
- support development proposals
- object to a new or existing TPO
- challenge a refusal decision
This includes:
- detailed tree condition assessment
- structural, safety or damage analysis
- planning context and amenity evaluation
- proportionate work recommendations
- evidence aligned with LPA decision criteria
The aim is simple:
clear, defensible justification that meets the standards LPAs require.
The TPO Application & Appeal Process
| Step | Description |
|---|---|
| 1. Initial Review | Send decision notices, photos and the site address. |
| 2. On-Site Assessment | Condition, risk, amenity and structural context evaluated. |
| 3. Justification Drafting | Clear reasoning supporting works, variation or appeal. |
| 4. Submission or Appeal | Guidance on required documentation and next steps. |
| 5. Outcome Support | Additional evidence supplied if requested by the LPA. |
Our Approach
Evidence First
Every recommendation justified with clear arboricultural reasoning.
Proportionate
Work recommendations matched to real, not perceived, risk.
Planning Led
Reports structured around LPA decision-making frameworks.
Strategic
Approach tailored to raise acceptance likelihood and avoid unnecessary escalation.
Do I need a TPO application or appeal?
You’re likely to need one if:
- a tree you want to prune or remove is protected
- the LPA has refused previous works
- storm damage has created new safety concerns
- the tree is causing structural, surface or drainage damage
- an objection has been raised to proposed development
- you’ve received notice of a new or provisional TPO
- a neighbour’s tree affects your property and is under TPO control
If a tree is protected, any works require formal, well-justified approval.
What your TPO Application or Appeal includes
A focused, planning-ready package:
- full tree condition and safety assessment
- structural and physiological evaluation
- identification of defects, decay or stability issues
- proximity and constraint analysis
- justification for pruning or removal
- supporting evidence for objections or appeals
- amenity assessment aligned with LPA criteria
- recommended alternatives (if applicable)
- clear, proportionate reasoning
Why this Matters for Planning
LPAs assess TPO decisions under the Town & Country Planning Act 1990, the Tree Regulations 2012 and established amenity and risk criteria.
They expect clear evidence demonstrating:
- condition and structural stability
- safety and foreseeable hazards
- proportionality of proposed works
- impact on public amenity
- interaction with built structures
- reasonable alternatives
Weak or ambiguous applications often lead to:
- refusals
- delayed decisions
- repeat submissions
- appeals requiring stronger justification
A clear, technical justification improves acceptance and reduces friction.

Case Note
Detailed assessment identified a significant stem cavity and a history of branch drop. Risk evaluation supported targeted reduction rather than full removal. Revised works were approved, and the extension progressed without further arboricultural objections.
TPO FAQs
What is a Tree Preservation Order (TPO)?
A Tree Preservation Order is a legal protection placed by a Local Planning Authority (LPA) to safeguard trees that provide public amenity value. Once in place, consent is required before carrying out works such as pruning, felling, or root disturbance.
When do I need to apply for TPO consent?
You must apply for consent if any works are proposed to a tree covered by a TPO, including pruning, crown reduction, or removal. Undertaking works without approval can result in enforcement action and significant fines.
How do I apply for tree works under a TPO?
Applications are submitted to your Local Planning Authority using the standard TPO application form. Supporting arboricultural justification is typically required to ensure the proposal is valid and can be assessed efficiently by the council.
What information is required for a TPO application?
A valid application will usually include:
- A clear specification of proposed works
- A tree location plan
- Supporting arboricultural reasoning (condition, safety, or management justification)
- Photographic evidence where appropriate
Providing robust technical justification significantly improves the likelihood of approval.
How long does a TPO application take to be decided?
Local Planning Authorities generally aim to determine TPO applications within 8 weeks. Complex cases or insufficient information may result in delays or requests for further details.
What are valid reasons for carrying out works to a TPO tree?
Applications are more likely to be approved where there is clear justification, such as:
- Tree health decline or structural defects
- Safety risks to people or property
- Management of excessive shading or encroachment (with evidence)
- Good arboricultural practice
Requests based purely on preference or minor inconvenience are less likely to succeed.
Can a Tree Preservation Order be removed or overturned?
Yes, but only in specific circumstances. A TPO can be challenged or modified if it is no longer justified, for example where the tree has declined significantly or no longer contributes to public amenity. This typically requires formal evidence and professional input.
How do you appeal a refused TPO application?
If your application is refused, or approved with conditions you disagree with, you can appeal to the Planning Inspectorate. Appeals must be submitted within a set timeframe and should include robust arboricultural evidence to support your case.
How successful are TPO appeals?
The success of an appeal depends on the strength of technical justification. Appeals supported by clear arboricultural evidence, such as structural defects or management necessity, are more likely to succeed than those based on subjective concerns.
Can I carry out emergency work on a TPO tree?
Yes, but only where the tree poses an immediate risk of serious harm. In these cases:
- Only the minimum necessary work should be undertaken
- Evidence (such as photographs) should be recorded
- The Local Planning Authority should be notified as soon as possible
Misuse of this exemption can lead to enforcement action.
What happens if I carry out work without TPO consent?
Unauthorised works to a protected tree are a criminal offence. Consequences can include:
- Unlimited fines in serious cases
- A legal requirement to plant a replacement tree
- Potential prosecution
Compliance with TPO regulations is essential.
How do I check if a tree is protected by a TPO?
You can check directly with your Local Planning Authority or via their online mapping systems. For example, you can review TPO constraints through your council’s planning portal, such as:
https://www.planningportal.co.uk/permission/common-projects/trees-and-hedges/tree-preservation-orders
Professional arboricultural input can also confirm constraints and advise on next steps.
Can neighbours object to TPO applications?
Yes, TPO applications are subject to consultation. Neighbours and other stakeholders may submit comments, which the Local Planning Authority will consider as part of the decision-making process.
Do I need an arboricultural consultant for a TPO application or appeal?
While not mandatory, professional input significantly improves outcomes. A qualified arboricultural consultant can:
- Provide technical justification
- Ensure applications are valid and policy-compliant
- Support appeals with structured evidence
This reduces the risk of refusal and delays.
What is the difference between a TPO and a Conservation Area restriction?
A TPO provides specific legal protection to individual trees or groups, whereas Conservation Area protection applies to all trees above a certain size within a designated area. Both require formal notification or consent before works are undertaken.
