There are a few things we need to consider before we even touch your trees.
The first is the council you are in, and whether your tree is on the exemption list.
I say shouldn't because according to council you don't need one... but we always like to double check in case they have introduced a new clause in the last few months.
If you don't see your council above, never fear!
Drop me a note and let me know which council you are in and I'll see whether or not your trees are in the exempt list.
