Conservation Areas vs Tree Preservation Orders
Both conservation areas and TPOs protect trees, but they work differently. Understanding which applies to your tree determines what process you need to follow.
Key differences
| TPO | Conservation area | |
|---|---|---|
| What is protected | Specific trees named in the order | All trees with trunk diameter over 75mm at 1.5m height |
| Process | Apply for consent (8-week decision) | Give 6 weeks' notice (authority can make a TPO or let it expire) |
| Penalty for breach | Unlimited fine | Unlimited fine |
| Replacement duty | Automatic — landowner must replant | Authority can issue a tree replacement notice |
Can a tree have both?
Yes. A tree can be in a conservation area and also have a TPO. When both apply, the TPO rules take precedence — you need to apply for consent rather than just giving notice.
Notice vs consent
The conservation area process is a notificationsystem, not a consent system. You give the authority six weeks' notice of your proposed work. During that period, the authority can either make a TPO (which blocks the work until consent is granted) or let the six weeks expire, after which you can proceed.
With a TPO, you need active consent before doing anything. The authority has eight weeks to decide, and silence does not mean approval — if they do not respond, you can appeal to the Planning Inspectorate, but you cannot simply start work.
