When a tree is both in a conservation area and protected

Where a tree is covered by a Tree Preservation Order and also stands in a conservation area, only one procedure applies. The Order wins. Section 211 of the Town and Country Planning Act 1990, which requires six weeks' notice for works to conservation area trees, does not apply to a tree that is already the subject of an order.

So the answer to the conservation area and TPO tree question is: apply for consent under the Order, and forget the six-week notice. Doing both wastes time. Doing only the notice leaves you exposed to prosecution.

How the two regimes sit together

They exist for different reasons. A Tree Preservation Order is a deliberate act by the council protecting a particular tree, group or woodland it has assessed as worth keeping. Conservation area protection is automatic and applies to every qualifying tree in the area, whether anyone has looked at it or not.

Section 211 is best understood as a screening mechanism rather than a protection. It gives the council six weeks to decide whether to make an order. It does not give it the power to refuse.

That is why the overlap is resolved the way it is. Once an order exists, the council has already made the decision that section 211 was there to prompt, and the notice procedure has nothing left to do.

A tree can move between regimes. A section 211 notice frequently produces a Tree Preservation Order within the six weeks, and from that moment the tree is in the order regime and the notice is spent.

Which procedure takes precedence

Practical consequence, laid out:

Both are submitted on the same standard tree works form, which covers works to protected trees and notification of works in a conservation area. Tick the right box. A notice submitted for a tree under an order may simply be treated as invalid, and the six weeks you thought were running were not.

Check both designations before doing anything. The council's tree officer holds the order register and the conservation area boundary, and national planning data is published openly, though the definitive record is the council's.

Timing differences between them

The six weeks under section 211 is a waiting period. Nothing is decided at the end of it. If the council has made no order, you may carry out the works described in the notice at any time within two years.

The eight weeks under the Order is a determination period. At the end of it there is a decision, and if the council has not decided you cannot simply proceed. There is no deemed consent.

That difference matters when scheduling contractors. A conservation area notice can be served in February for works in August. An application for consent has to be granted before the saw comes out, and a refusal turns an eight-week wait into an appeal that takes months.

Where works to protected trees are needed as part of a development, they are better handled through the planning application itself, since works authorised by a full planning permission are exempt from the order controls. That route only works where the trees and the works are clearly described in the approved drawings, which is one more reason for an accurate tree survey.

Works exempt under one but not the other

The exemptions overlap but they are not identical, and this is where householders get into trouble.

Both regimes exempt dead trees, though the Order regime requires five working days' written notice before a dead tree is cut down, except in an emergency. Both allow work needed urgently to remove an immediate risk of serious harm, with notice given as soon as practicable afterwards. Both exempt works required by an Act of Parliament, and works by certain statutory undertakers.

Differences to watch:

• Size. Section 211 does not apply to a tree whose diameter, measured at 1.5 m above ground, does not exceed 75 mm, or 100 mm where the work is thinning to improve the growth of other trees. A Tree Preservation Order applies to the trees it names regardless of size.
• Fruit trees. The Order regime exempts work on fruit trees cultivated for fruit production where the work is in the interests of that production. Section 211 has no equivalent.
• Abating a nuisance. Both allow works to abate a nuisance that could be sued upon at law, and both are routinely misunderstood. The test is legal nuisance, not inconvenience. Overhanging branches may be cut back to the boundary at common law, but that right does not override either regime.

"Dead" and "dangerous" are the two words that cause most prosecutions. A tree in poor condition is not dead. A tree that might one day fail is not dangerous in the sense these exemptions use. Get a written arboricultural opinion before relying on either, and photograph the tree before the work.

What the council's tree officer checks

Officers assessing a submission look at a short list.

Whether the works are specified properly, using recognised terminology rather than "reduce" or "tidy up". Writing that specification is a discipline of its own, covered in pruning specifications and writing them properly.

Whether the stated reason is supported. A subsidence claim needs the engineering evidence. A light complaint is not a planning reason, though it will be weighed.

Whether the tree contributes to the character of the area, which under an order is the test that led to the designation, and in a conservation area is the test for making one.

Whether replacement planting is offered, and where. And whether the applicant is the person entitled to carry out the works, since consent does not confer any right over someone else's land.

Trees in the setting of a listed building bring a further consideration, set out in trees in the setting of a listed building.

Penalties under each regime

Section 210 of the 1990 Act makes it an offence to cut down, uproot, wilfully destroy, or wilfully damage a protected tree in a way likely to destroy it, and the penalty on conviction can be an unlimited fine. Lesser contraventions attract a lower maximum. Conservation area trees are protected on equivalent terms while the notice period runs or where no notice was given.

Fines are not the whole exposure. Replacement duties apply: where a protected tree is removed in breach, the landowner comes under a duty to plant a replacement of appropriate size and species at the same place, and the council can enforce that duty by notice. That obligation attaches to the land and passes to a future owner.

Contractors are prosecuted too. A tree surgeon who fells a protected tree on a householder's instruction can be convicted alongside the householder, which is why reputable firms ask to see the consent before quoting.

Larger-scale felling brings a separate licensing regime into play, and the interaction is set out in woodland felling licences and when planning is not enough.

Practical steps before any work

1. Ask the council in writing whether the tree is subject to an order and whether it stands in a conservation area. Keep the reply.
2. If an order applies, apply for consent and wait for the decision.
3. If only conservation area protection applies, serve the section 211 notice and wait six weeks.
4. Commission a written arboricultural opinion where you intend to rely on the dead or dangerous exemptions, and photograph the tree first.
5. Give the contractor a copy of the consent or the notice, and do not let work start without it.
6. Where replacement planting is conditioned, diarise it, because failing to plant is itself enforceable.
