Permitted Development Rules for a Tree Removal
Whether you need consent depends on the tree's protection status. Trees with a Tree Preservation Order (TPO) cannot be removed, topped, lopped, or uprooted without the council's consent. Trees in conservation areas require 6 weeks' written notice to the council before any work. Unprotected trees on your own land can generally be removed without permission.
Conditions
- 1Trees with a TPO: must obtain consent from the council before any work (including pruning)
- 2Trees in conservation areas: must give 6 weeks' written notice to the council (Section 211 notice)
- 3Unprotected trees on your own land: no permission normally needed
- 4Dead, dying, or dangerous trees: TPO consent is still technically required but councils usually grant it
- 5Felling licence from the Forestry Commission may be needed if removing more than 5 cubic metres of timber in a calendar quarter
Size and Dimension Limits
- Not applicable; the issue is the tree's protection status
When Permitted Development Does Not Apply
- Breaching a TPO is a criminal offence with fines up to £20,000 (magistrates' court) or unlimited (Crown Court)
- Working on a tree in a conservation area without notice is an offence
- Neighbours' trees: you may trim branches overhanging your property but must return the cuttings
- High hedges: covered by separate legislation (Anti-social Behaviour Act 2003, Part 8)
What About Building Regulations?
Building regulations approval is not usually required
Building Regulations do not apply to tree removal. However, if removing a tree near a building on clay soil, the ground may swell (heave), potentially affecting foundations. A structural engineer or arboriculturist should advise if the tree is within influencing distance of a building.
Building regulations are separate from planning permission. Even if your project is permitted development, you may still need building regulations approval. Contact Welwyn Hatfield building control or use an approved inspector.
How to Apply in Welwyn Hatfield

If your project is permitted development and you want written confirmation, you can apply for a Lawful Development Certificate (LDC) from Welwyn Hatfield. This provides proof that your project does not need planning permission, which can be helpful when selling your property.
What Happens If I Build Without Permission?
High risk for protected trees. Breaching a TPO is a criminal offence with significant fines. The council can also require you to plant a replacement tree. Work on trees in conservation areas without notice is also an offence, and the council can impose a TPO retrospectively.
