Replacement tree conditions and how councils enforce them

A replacement tree condition outlives the building work by years, which is why it catches householders long after they have filed the decision notice. The standard form requires planting in the first available planting season after the development is finished, and then requires you to replace any tree that dies, is removed or becomes seriously damaged or diseased within five years, with another of similar size and species, in the next planting season.

That five year tail is enforceable. So is the separate statutory duty that arises when a tree covered by a preservation order comes down. The two obligations are often confused, and they work differently.

The condition on your permission

Landscaping conditions are imposed under section 70 of the Town and Country Planning Act 1990 and have to meet the six tests in national guidance, including being necessary and enforceable. A well drafted one names the species, the stock size, the planting positions on an approved drawing, and the maintenance period.

Read yours before you plant anything. Three details decide what you actually owe.

The trigger. Some conditions run from completion of the development, some from first occupation, some from the date of planting. That start date sets when the five years end.

The specification. Nursery stock sizes matter. A condition asking for extra heavy standard trees is not satisfied by whips from a garden centre, and an officer with a tape measure can tell.

The substitution clause. Many conditions allow a different species with the prior written approval of the council. Where that clause exists, use it. Where it does not, the condition means what it says.

The statutory duty after a protected tree is removed

Section 206 works independently of any planning permission. Where a tree protected by a preservation order is removed, uprooted or destroyed in contravention of the order, the landowner has a duty to plant another tree of an appropriate size and species at the same place, as soon as they reasonably can.

The point people miss is that the duty also applies where the tree was removed lawfully because it was dead or presented an immediate risk. The exemption in the regulations removes the need for consent. It does not remove the duty to replant. Councils can and do dispense with the duty on application, and that dispensation has to be asked for rather than assumed.

The replacement then becomes subject to the original order automatically, so the new tree is protected from the day it goes in.

Where the tree stood in a conservation area rather than under an order, a comparable duty applies under section 213 following removal without the required notice.

How enforcement actually arrives

Councils have three routes, and which one they pick tells you how much trouble you are in.

For a breach of a planning condition, a breach of condition notice under section 187A is the usual instrument. It specifies the steps needed to secure compliance and gives a period of not less than 28 days. There is no right of appeal against it. Failing to comply is a criminal offence prosecuted in the magistrates court, which is why arguing about the species before the notice arrives is so much better than arguing after.

An enforcement notice under section 172 is also available and does carry appeal rights, though for planting failures the breach of condition notice is quicker.

For the statutory replanting duty, the instrument is a tree replacement notice under section 207. It must specify the trees, sizes, species and the period for compliance, and it can be served within four years of the date of the failure to replant. Appeals go to the Secretary of State under section 208, on grounds that include that the duty does not apply or that the requirements are unreasonable.

Enforcement is discretionary, so practice varies between councils. What does not vary is that a tree officer who has been ignored twice tends to formalise things.

Buyers ask about this at conveyancing. An unresolved planting obligation shows up in the local search as an outstanding condition, and it can delay a sale while the parties argue about who plants the tree. Clearing it before marketing is faster than negotiating a retention.

Getting the condition changed rather than breached

If the planting requirement is wrong, change it. An application under section 73 to vary or remove a condition is determined on the planning merits of that condition alone, and a well evidenced application supported by an arboricultural note usually succeeds where the original species is unsuited to the ground conditions or the position conflicts with a drainage run.

Bring evidence rather than preference. A soil assessment, a photograph of the failed stock and a short statement from an arboriculturist explaining why a field maple will establish where a beech will not is a persuasive package. A note saying the tree blocks the light is not.

There is a second route where the planting has been done and the council disputes the detail. A non-material amendment application under section 96A can correct a species name or a planting position that was recorded wrongly on the approved drawing. It is a light touch application with a short determination period, and it works only where the change really is non-material. Moving two trees a metre along a boundary qualifies. Halving the number does not.

Where the works themselves are still being designed, an arboricultural impact assessment prepared to BS 5837:2012 sets out the root protection areas, the trees to be retained and the mitigation planting, and it is far easier to agree planting positions at that stage than to renegotiate them under a notice. A landscape strategy does the same job at scheme level where several trees are involved.

Practical sequence for a householder

1. Find the decision notice and read the landscaping and tree conditions in full, including any drawing they refer to.
2. Diarise the end of the maintenance period, and the next planting season, which runs roughly from November to March for bare root stock.
3. Photograph the planting when it goes in, with a dated image showing the stock size.
4. If a tree fails, tell the tree officer in writing before the next season, with the reason and your proposed replacement.
5. Keep receipts and the nursery specification. Compliance is proved on paper.

Illustrative example: a rear extension is permitted with a condition requiring two semi-mature hornbeam along the boundary, maintained for five years. One dies in the second summer after a dry spring. The owner emails the tree officer in September with a photograph and a proposal to replant in December with the same species and improved topsoil. No notice is served. Had the failure gone unreported until year six, the council could still have relied on the condition because the five year period had not expired at the time of the failure. This example is illustrative.

The wider point for anyone planning work near trees is that the planting obligation is designed at application stage. Councils rarely refuse over a species choice, and they do refuse where a scheme offers no replacement for what it removes.
