Emergency tree works and evidencing an immediate risk
The exemption for urgent tree works is judged after the event, and the burden sits with whoever did the cutting. What to photograph, what to write down and when notice is due.
Emergency tree works on protected trees are lawful only where the works are urgently necessary to remove an immediate risk of serious harm, and the burden of proving that sits with the person who did the cutting. The Town and Country Planning (Tree Preservation)(England) Regulations 2012 exempt those works from the need for consent, along with works to a dead tree, but the exemption is judged after the event against whatever record exists. No record means no defence.
Landlords and managing agents get caught by this more often than anyone, because the call usually comes at night from a tenant.
What immediate risk of serious harm means
Three words are doing the work, and each narrows the exemption.
Immediate means now, not in six months. A tree with advanced decay that will probably fail within a season is a hazard to be managed through an application, not an emergency. Serious harm means harm to people or property of a meaningful order, not inconvenience. And urgently necessary means the works could not reasonably have waited for consent, which is a harder test than it sounds given that most authorities will deal with a pressing case in days.
The tree being dead is a separate exemption with its own procedure, and it is not the same thing as dangerous. A dead tree in the middle of a paddock endangers nobody.
Courts and authorities assess all of this objectively, on the facts as they were at the moment of the decision. Your honest belief that the tree was about to fall is not the test, though contemporaneous evidence of why you believed it is exactly what supports the conclusion that a reasonable person would have thought the same.
The evidence to gather before the saw comes out
Where there is any time at all, and there usually is a few hours, gather the record first. Ten minutes on site before the works are the difference between a defensible position and an enforcement file.
- Photographs of the defect from several angles, with something in frame for scale and the whole tree visible in at least one shot.
- Photographs of the target: the footpath, the road, the conservatory, the parked cars, whatever the failure would land on.
- A note of the date, time, weather and who attended.
- The name and qualification of whoever assessed the tree, and their reasoning in a sentence or two.
- Any attempt made to contact the council's tree officer or out of hours service, with the time of the call.
That last item carries disproportionate weight. A logged call at 21:40 saying the council could not be reached, followed by works at 22:15, reads very differently from silence.
Photographs, reports and timestamps
Digital photographs carry embedded capture times, and those are far more persuasive than a date written on a file afterwards. Do not strip the metadata by re-saving images through a messaging app before you archive them.
Where a tree surgeon or arboriculturist attends, ask for a short written statement rather than an invoice line. It needs to say what was observed, what failure mode was expected, why the risk was immediate, and what works were judged necessary to remove it. Half a page is enough. A retrospective report written three weeks later carries much less weight than one written that evening.
Keep physical evidence where you can. A section through the stem showing the extent of decay, or a failed limb retained on site, lets a tree officer see what you saw. Councils frequently ask for exactly this, and its absence is often what turns a routine notification into an investigation.
Notifying the authority, and when
The two exemptions have different notice arrangements, and mixing them up is a common error.
| Situation | Notice requirement |
|---|---|
| Tree is dead | written notice to the authority before the works, with a short period to allow inspection |
| Works urgently necessary to remove an immediate risk of serious harm | written notice as soon as practicable after the works are carried out |
| Tree in a conservation area, not otherwise protected | section 211 notice, six weeks, unless an exemption applies |
Give the notice in writing even where a phone call has already been made, address it to the tree officer by name if you have one, attach the photographs, and keep proof of sending. Do not wait for a reply before archiving the file.
For trees in a conservation area that are not subject to an Order, the ordinary route is a six week notice under section 211 of the Town and Country Planning Act 1990. The same emergency exemptions apply, and the same evidential burden comes with them.
Limiting the works to what is necessary
The exemption covers works to the extent they are necessary to remove the immediate risk. Not a metre more.
This is where otherwise defensible cases fall apart. A hanging limb over a footpath justifies removing the limb and, if access requires it, some adjacent branches. It does not justify felling the tree to ground level because the contractor was there anyway and one visit costs less than two.
Ask whether a lesser intervention removes the immediate risk: taking the failed limb, reducing an end-weighted branch, propping, or closing off and fencing the target area until consent can be obtained. Fencing off is frequently the correct answer and almost never the one that gets chosen, because it is inconvenient.
Where the tree is retained, plan the follow-up. A remedial specification written properly afterwards, along the lines set out in writing pruning specifications properly, turns an emergency into a managed programme.
The replacement duty afterwards
Removing a protected tree under an exemption triggers a duty under section 206 of the Town and Country Planning Act 1990 to plant a replacement of appropriate size and species at the same place, as soon as reasonably practicable. The replacement is then protected by the original Order.
Authorities can dispense with that duty on application, and frequently will where the planting position is unsuitable. Ask rather than assume, and ask in writing. An unplanted replacement is enforceable by notice.
If the tree stood within a development site, check whether its loss affects an approved tree protection plan or a Tree Survey submitted with an application, because conditions may require the scheme to be updated.
Where insurers and councils pull in opposite directions
Subsidence claims produce the sharpest version of this conflict. An insurer's arboricultural report may recommend removal of a protected tree, and the council may take the view that the evidence linking the tree to the damage is incomplete.
An insurer's recommendation is not an exemption. The emergency provisions concern immediate risk of serious harm from the tree itself, not gradual structural damage to a building, and subsidence cases run through the consent process with monitoring data rather than through the emergency route. That evidential argument is set out in trees and subsidence claims on neighbouring property.
Where the two positions cannot be reconciled, apply for consent and keep the correspondence. A refusal can be appealed, and compensation provisions exist in some circumstances. Cutting first and arguing later is the one route that closes off the others.
This is general guidance, not legal advice. Contravening a Tree Preservation Order is a criminal offence, so check the position with your local planning authority or a qualified arboriculturist before any works to a protected tree.

Frequently asked questions
Can I cut down a protected tree in an emergency?
Only so far as the works are urgently necessary to remove an immediate risk of serious harm. That exemption in the 2012 Regulations is narrow: the risk must be present rather than foreseeable, the harm meaningful, and waiting for consent unreasonable in the circumstances. The burden of proving all three falls on whoever carried out the works.
Do I have to tell the council before urgent tree works?
For urgent works to remove an immediate risk, written notice is given as soon as practicable after the works. For a dead tree the notice comes before the works, with a short period allowing the authority to inspect. Give notice in writing with photographs attached even if you have already spoken to someone by telephone.
What evidence should I collect before emergency tree works?
Photographs of the defect from several angles with something for scale, photographs of what the failure would land on, the date, time and weather, the name and qualification of whoever assessed the tree, and a log of any attempt to contact the council. Keep the original image files so the capture times survive.
Do I have to replace a protected tree that was removed?
Yes. Section 206 of the Town and Country Planning Act 1990 places a duty to plant a replacement of appropriate size and species in the same place as soon as reasonably practicable, and the replacement carries the original Order's protection. Authorities can dispense with the duty on request, so ask in writing rather than assuming.
Can I remove a tree because my insurer says it causes subsidence?
Not under the emergency exemption. That provision addresses immediate risk of serious harm from the tree itself, not gradual damage to a building. Subsidence cases go through the ordinary consent route supported by monitoring and root identification evidence. An insurer's recommendation carries no weight as an exemption if the works are later challenged.
