No species is protected automatically
UK tree protection works by location, not by species. There's no list of protected tree types, so an oak, a beech or a yew is treated the same way as a sycamore or a conifer.
That said, oaks are protected more often than most trees in practice. They're large, long-lived and prominent, which are exactly the qualities councils look for when they decide a tree is worth a Tree Preservation Order.
When an oak is protected
- It has a Tree Preservation Order, either on its own, in a group, or as part of an area or woodland order.
- It stands in a conservation area and has a trunk more than 75mm across at 1.5m high, so six weeks' notice is needed before work.
- A planning permission for the property includes a condition requiring it to be kept.
- It's in woodland, where felling more than five cubic metres of timber a quarter usually needs a felling licence.
If none of these apply, you can generally work on an oak on your own land without the council's permission.
Ancient and veteran oaks
Very old oaks are often described as ancient or veteran trees. National planning policy in England treats them as irreplaceable, so a council will strongly resist development that would harm one.
That policy shapes planning decisions. It doesn't stop an owner felling an unprotected veteran oak outside the planning process, but councils often make a TPO quickly if they learn one is at risk. If you own a very old oak, assume the council will take an interest.
Wildlife rules that apply to every oak
A mature oak supports more wildlife than almost any other native tree, and wildlife law applies whether or not the tree is protected:
- Bat roosts are protected, and old oaks with cavities, loose bark or splits often contain them. Disturbing or destroying a roost is an offence.
- Nesting birds are protected while the nest is in use, roughly March to August.
A good tree surgeon will look for signs of both before felling, and a bat survey may be needed for a large, old tree.
What to check before working on an oak

- 3Check the planning history for conditions on trees.
- 4Ask your tree surgeon to check for bats and nesting birds.
- 5Get any consent or notice acknowledgement in writing before the work.
