Finding Tree Preservation Orders and checking coverage

A Tree Preservation Order is two things: a document with a schedule listing the trees, and a map identifying where they are. Neither tells you the answer on its own. The schedule says what is protected and how it is classified. The map says where. Read one without the other and you will get it wrong, which is how householders end up prosecuted for felling a tree they were told was not on the order.

Start with the council, because the council holds the legal record.

Where the records live

Three places, in this order of reliability.

The local planning authority holds the sealed order, the schedule and the definitive map, and must make them available for public inspection. Many councils publish a searchable tree preservation order layer on their planning constraints map, and some publish scanned order documents alongside it.

The national planning data service publishes tree preservation order, tree preservation zone and tree datasets supplied by authorities. Coverage is uneven, because it depends on each council digitising and submitting its orders, and older paper orders are frequently absent. A blank result there proves nothing.

A local authority search on a purchase will report tree preservation orders affecting the property. It reports what the council tells it, at the date of the search, so it is a snapshot rather than a check you can rely on years later.

The pattern is the same one that applies to other legally recorded lines. The published map is a convenience and the sealed record governs, which is exactly the position described in checking public rights of way on the definitive map.

Reading the schedule and the map together

Pull both documents and work through them in this order.

1. Find the order reference and the date it was made and confirmed. A provisional order takes effect immediately and has to be confirmed within six months, so check that confirmation happened.
2. Read the first schedule. Trees are listed by number against a classification: individual trees as T1, T2 and so on, groups as G1, woodlands as W1, areas as A1.
3. Locate the same numbers on the map. Individual trees appear as dots with the tree number, groups and woodlands as outlined areas, area classifications as hatched or shaded polygons.
4. Match the species descriptions in the schedule against what is actually growing. Orders from the 1970s and 1980s often describe species loosely, and trees have been felled, replaced and self-seeded since.
5. Note the boundary of the order against your title plan. A tree on a boundary can be rooted in a neighbour's land while overhanging yours, which changes who applies for consent.

The mismatch between schedule and ground is normal on older orders. Where a listed T4 oak is no longer there and a large sycamore stands three metres away, the order does not automatically transfer. That is a question for the tree officer rather than for you.

Individual, group, area and woodland

The four classifications protect different things, and the difference matters.

An individual classification protects a named tree at a mapped point. Straightforward.

A group classification protects the trees identified as a group, where the value lies in their combined contribution. The schedule should say how many trees of each species the group contains, and that number is what is protected.

A woodland classification protects all trees within the mapped woodland, including trees that grow or are planted after the order was made. It is designed for woodland managed as woodland, and the Forestry Commission's felling licence regime interacts with it.

An area classification protects the trees of the specified kinds standing within the mapped area at the date the order was made. Only those trees. Anything that grew afterwards is outside the order.

The trap in area orders

That last point is worth stating twice, because it produces bad advice in both directions.

An area classification made in 1978 protects the trees that were standing in 1978. A tree planted in 1995 within the same polygon is not protected by that order, even though the council's map layer shows the polygon covering it. Equally, a mature tree inside the polygon almost certainly was standing in 1978 and is protected, whatever anyone assumes about the map being out of date.

Planning Practice Guidance treats area classifications as a temporary measure, to be replaced with individual, group or woodland classifications once the authority has surveyed properly. Many councils never did. So if your tree sits inside an area classification, the question becomes evidential: was this tree here when the order was made? Historic aerial photography, successive Ordnance Survey editions and the tree's own girth and growth rate are how that gets answered, and an arboriculturist's report estimating age carries more weight than your recollection.

Conservation area protection as well

An order is not the only control. In a conservation area, section 211 of the Planning (Listed Buildings and Conservation Areas) Act 1990 requires six weeks written notice to the council before cutting down, topping, lopping or uprooting a tree, whether or not any order exists.

The 2012 Regulations set a diameter threshold below which the notice is not required, measured at 1.5 metres above ground level, with a higher figure where the work is thinning to help the growth of other trees. Measure it properly with a diameter tape rather than estimating, and record the measurement.

So a property can be caught by both regimes, or by the conservation area notice alone. Check both before you instruct a contractor. The same caution about relying on published datasets applies to ecological records, as set out in reading habitat inventories and classification data.

Asking the tree officer to confirm

Write to the council rather than telephoning, and ask four specific questions:

• Is the tree at the stated location subject to a Tree Preservation Order, and if so what is the order reference, the tree number and the classification?
• Was the order confirmed, and on what date?
• Is the property within a conservation area for the purposes of section 211?
• Does the council hold any record of the tree having been planted after the date of the order?

Attach a plan with the tree marked and a photograph. Keep the reply. Councils generally answer these promptly because a written answer protects them too, and a dated email from a tree officer is the document that resolves a dispute with a contractor or a buyer's solicitor later.

What to do when the records conflict

Conflicts arise often enough to plan for. The schedule lists a species that is not there. The map dot sits between two trees. The council's online layer shows a polygon that the scanned order does not. The order was never confirmed.

Three rules resolve most of these. The sealed order and its map are the legal record, so a discrepancy with an online layer is resolved in favour of the sealed document. Where the sealed document is ambiguous, the question is what a reasonable person reading the order and map together would understand to be protected. And where genuine doubt remains, treat the tree as protected and apply for consent, because the consequences of being wrong run one way only.

Where trees affect a development proposal rather than a single pruning decision, the document you need is a survey to BS 5837:2012 setting out the tree schedule, root protection areas and constraints. Councils usually expect a suitably qualified author for that work and professional review is strongly advised, so treat a tree survey draft as a starting point for an arboriculturist.
