Understanding the Difference Between TPO and Conservation Area Applications for Tree Work
When planning tree work, it’s essential to know whether your trees are protected. In the UK, two common forms of protection are Tree Preservation Orders (TPOs) and Conservation Areas. While both aim to safeguard trees, the application processes and legal requirements differ significantly.
What is a TPO Application?
A Tree Preservation Order (TPO) is a legal protection placed on specific trees or woodlands by a local authority. Its purpose is to prevent unnecessary removal or inappropriate pruning.
If a tree is covered by a TPO:
You must submit a formal application to the local planning authority before carrying out any work.
The application should include detailed information about the proposed work and the reasons for it (e.g. safety concerns, structural damage, tree health).
The authority has up to 8 weeks to make a decision.
Consent must be granted in writing before any work begins.
Importantly, carrying out unauthorised work on a TPO tree can result in significant fines.
What is a Conservation Area Application?
Conservation Areas protect the overall character and appearance of a location, which includes its trees. Unlike TPOs, protection applies broadly rather than to specific trees.
If your tree is in a Conservation Area:
You are required to submit a Section 211 Notice (often called a “Conservation Area notification”).
This is not a full application but a notice of intent to carry out work.
The local authority has 6 weeks to respond.
During this period, they may:
Allow the work to proceed, or
Decide to place a TPO on the tree, which then requires a full TPO application.
If no response is received within 6 weeks, you may proceed with the work as described in your notice.
