Can a protected tree be felled once permission is granted

Yes, sometimes. The Town and Country Planning (Tree Preservation) (England) Regulations 2012 exempt work to a protected tree where that work is necessary to implement a full planning permission. The exemption is real and it is used every week. It is also much narrower than the phrase suggests, it does not apply to outline permissions or to permitted development, and a condition on your own permission will usually take it away again.

The exemption in the regulations

Regulation 14 of the 2012 Regulations lists the circumstances in which consent is not required for cutting down, topping, lopping or uprooting a tree covered by a Tree Preservation Order. One of those is work that is necessary to implement a planning permission, and the regulation expressly excludes outline planning permission and permission granted by a development order.

Three words in that formulation do the work.

Necessary. Not convenient, not less expensive, not preferred by the groundworks contractor. The test is whether the approved development can be built without removing or cutting the tree.

Implement. The permission has to be capable of implementation and the works have to be part of carrying it out, rather than tidying the site beforehand.

Full. An outline permission does not qualify, and neither does anything you are doing under permitted development rights.

The same logic runs through the conservation area regime. Where a tree in a conservation area is not covered by an order, the usual six week notice under section 211 is not required where the work is necessary to implement a full permission, and the same narrow reading applies.

Why necessary is narrower than it sounds

The question is objective, judged against the approved drawings. If the building footprint sits three metres clear of the trunk and the tree could survive with a no-dig driveway construction, felling it is not necessary. It may be easier. That is a different thing.

Authorities apply the test by comparing the approved plans with the tree's root protection area and crown. Where the approved layout physically conflicts with the tree, the exemption applies to the extent of that conflict. Where the layout could accommodate the tree with a buildable engineering solution, it does not.

Partial works follow the same rule. If the permission requires the crown to be lifted so a vehicle can pass, the exemption covers the crown lift. It does not cover felling the tree because the crown lift would leave it looking unbalanced.

An arboricultural impact assessment prepared to the recognised standard is the document that answers this question, and it should have been prepared before the application went in. The tree survey and impact assessment page sets out what that work covers, and councils usually expect it from a suitably qualified author.

Outline permissions and reserved matters

An outline permission is expressly outside the exemption, and that is unambiguous. While a permission remains at outline stage with matters reserved, the exemption is unavailable however obvious the conflict looks on the parameter plan.

Once all reserved matters have been approved and the permission is capable of implementation, the position is less settled and practitioners take different views. The cautious approach, which is the one to take, is to write to the local planning authority setting out the position and asking for written confirmation before any work happens. Most tree officers will respond, and a two-line email costs nothing against the risk.

Where the permission was granted subject to a condition requiring approval of a tree protection plan and method statement, that condition has to be discharged first in any event, so the confirmation conversation happens naturally as part of the process described in discharging a tree protection condition without delay.

Works outside the approved plans

The exemption is bounded by the permission. Four situations fall outside it entirely.

• Trees not shown for removal on the approved plans, however inconvenient they turn out to be.
• Trees outside the application red line, including those in a neighbour's garden overhanging the site.
• Work carried out before the permission is capable of being implemented, for example before a pre-commencement condition has been discharged.
• Site clearance carried out for access, storage or welfare accommodation rather than to build the approved scheme.

That last one accounts for a large share of the enforcement cases. A contractor clears a corner of the site to put the compound somewhere sensible, and the corner contains a protected tree that the approved plans showed as retained.

Where a woodland order or a felling licence is in play the position is more complicated again, because forestry licensing runs on its own track, as set out in woodland orders and felling licences.

Conditions that put control back

Section 197 of the Town and Country Planning Act 1990 requires a local planning authority, when granting permission, to ensure whenever it is appropriate that conditions are imposed for the preservation or planting of trees. Authorities use that power routinely, and the effect is to remove the practical benefit of the exemption.

Breach of condition is enforceable through a breach of condition notice, against which there is no appeal, or through an enforcement notice. The council does not need to prove a Tree Preservation Order offence to act.

Replacement planting conditions deserve their own attention, because the specification determines whether the replacement survives, and the rules are covered in tree planting conditions.

What to do before the chainsaw arrives

Five steps, in order, and the whole sequence takes a fortnight at most.

1. Read every condition on the decision notice and identify anything touching trees, landscaping or site clearance.
2. Check the approved plans and confirm exactly which trees are shown for removal and which are retained.
3. Discharge any pre-commencement condition relating to tree protection, and get the written confirmation.
4. Write to the tree officer, naming the trees, quoting the permission reference and the plan that shows their removal, and stating that the works are considered necessary to implement the permission. Ask for acknowledgement.
5. Photograph the site and the trees, with dates, before work starts.

Brief the contractor in writing with a marked-up plan, not verbally on site. Site staff change, and the person who fells the wrong tree is rarely the person who was briefed.

If it goes wrong

Contravening an order by cutting down, uprooting or wilfully destroying a protected tree is an offence, and the penalty is an unlimited fine. Lesser damage is also an offence with its own penalty. There is a separate duty to replace trees removed in contravention of an order, and that duty attaches to the land.

Beyond the fine, the practical consequences bite. An authority that has lost a tree to an unauthorised felling will scrutinise the rest of your development closely, and the relationship matters over a two-year build.

As an illustrative example, a self-builder with full permission for a house whose approved plans show one category C sycamore removed and a category B oak retained instructs a contractor to clear the plot. The sycamore is exempt. The oak is not, the removal breaches the retention condition, and it is also an offence under the order. One afternoon, two separate legal problems, and a replacement planting requirement that will run for years.
