A "blanket TPO" is an informal term for an order that protects a whole area or woodland of trees at once, rather than named individual trees — most often an Area order or a Woodland order. It is not a distinct legal category. Understanding which of the four order types applies to your land matters, because they protect very different scopes of trees, and because getting it wrong can turn a routine bit of pruning into a criminal offence.
The four types of Tree Preservation Order
Every TPO is made in one of four forms under the Town and Country Planning Act 1990 and the Town and Country Planning (Tree Preservation) (England) Regulations 2012. The legal effect is identical in each case — you cannot cut down, top, lop, uproot or wilfully damage or destroy a protected tree (including cutting its roots) without the local planning authority's (LPA's) written consent. What differs is which trees are caught.
| Type | What it protects | Future trees covered? |
|---|---|---|
| Individual | One or more specifically named trees, each identified separately on the plan. | No |
| Group | A defined cluster of trees whose collective value (e.g. a screen or belt) justifies protecting them together. | No |
| Area | All trees within a mapped boundary that existed at the date the order was made. | No |
| Woodland | All trees within a woodland, including future and self-sown trees. | Yes |
Individual orders
The most precise type. Each protected tree is listed and marked on the order plan, often with its species. Because they are explicit, individual orders leave the least room for doubt about what is covered — useful when you are checking a single specimen before pruning or building nearby. If you are planning a BS5837 tree survey for development, individually protected trees will be flagged tree-by-tree in the schedule, so their status is rarely a surprise.
Group orders
A group order protects a collection of trees valued as a unit rather than for each tree's individual merit — a row screening a road, a belt sheltering a boundary, a cluster framing a view. The order names the trees within the group, but their justification is the combined amenity they provide. Removing one can undermine the value of the whole, which is why they are protected together. Don't assume a scrappy-looking tree in a group is fair game: its role in the group, not its solo quality, is what the order defends.
Area orders — the classic "blanket" order
This is what most people mean by a "blanket TPO." An Area order protects every tree within a drawn boundary at the moment the order was made. It was historically used as a quick way to safeguard the trees on a site under development pressure without surveying each one individually.
The critical limitation: an Area order only captures the trees present at the date it was made. Trees that grow, self-seed or are planted afterwards are not protected. Over time this makes older Area orders increasingly uncertain — you may need to establish whether a particular tree actually existed when the order was made, which for a 1970s order can be genuinely difficult to prove. For this reason, government guidance discourages new Area orders in favour of individual, group or woodland classifications, and many authorities are gradually re-surveying and replacing them. But large numbers of older Area orders remain in force.
Because an Area order sweeps up everything, owners are frequently caught out — a tree they assumed was unprotected turns out to sit inside a decades-old mapped boundary. Always check before you act, and never rely on the tree simply "looking ordinary".
Woodland orders
A Woodland order protects all the trees within a woodland — and, unlike an Area order, it extends to future trees, including natural regeneration and replacements. This reflects how woodlands work: they are dynamic, and protecting only the trees standing on one date would be meaningless. Normal woodland management (thinning, felling and replanting under good forestry practice) is still possible, but it requires the council's consent, and a felling licence from the Forestry Commission may also apply as a separate regime with its own volume thresholds. A Woodland order therefore casts the widest net of all four types.
Why the type matters to you
Knowing which order type applies changes what you can assume:
- With an individual or group order, only the named trees are protected — but check the plan carefully, as groups can be extensive.
- With an Area order, assume every mature tree in the boundary is protected unless you can positively show it post-dates the order.
- With a Woodland order, treat the whole wood — including saplings and regrowth — as protected.
A worked scenario: the "obviously unprotected" sycamore
Suppose you buy a house with a self-sown sycamore near the boundary that is plainly younger than the surrounding trees. Whether you can remove it depends entirely on the order type. Under an Area order made in, say, 1985, the sycamore is only protected if it existed in 1985 — a tree that clearly seeded in the 2000s is not caught, though you may have to evidence that to the tree officer. Under a Woodland order covering the same ground, that same self-sown sycamore is protected, because woodland orders capture regeneration. Same tree, same garden, opposite answer — which is exactly why the classification on the order, not the tree's appearance, is what you must check.
Consent, penalties and duration
Whatever the type, works to a protected tree need consent. An application for consent is decided within 8 weeks of valid receipt, and a granted consent is generally valid for 2 years; a refusal, conditional grant or non-determination can be appealed to the Planning Inspectorate. Confirmed orders last indefinitely — see how long a TPO lasts.
Unauthorised works are a criminal offence. Destroying a protected tree can bring a fine of up to £20,000 in the Magistrates' Court (unlimited if committed to the Crown Court), with lesser breaches attracting up to £2,500; courts weigh any financial benefit gained, and there is a duty to plant a replacement. There are narrow exemptions — genuinely dead trees (with five working days' prior notice to the LPA) and urgent works to remove immediate danger — but note the 2012 Regulations replaced the old "dead, dying or dangerous" test with the far narrower "dead" plus urgent-danger wording. Homeowners who still rely on the old phrase are a common casualty.
Requirements and registers are set locally — check your council
TPOs are made and administered by your local planning authority, so the register you must search, the map format, and the practical approach of the tree officer all differ from council to council. There is no single national TPO database — each authority holds and publishes its own orders, and how easy they are to find varies widely. Validation expectations for any development affecting protected trees are likewise set locally: some councils demand a full arboricultural package up front, others condition it.
You can see how tree protection surfaces in practice by comparing authorities such as Leeds, Bristol and Lambeth — an inner-London borough with dense conservation-area coverage will handle blanket protection very differently from a large northern authority with extensive woodland. PlanWatch tracks live tree-related planning activity council by council, so you can check how orders and applications are being handled in your own area and whether nearby trees already feature in local cases. Before doing any works, confirm the order and its plan with your authority.
Remember too that this is an England-centric picture. Wales, Scotland and Northern Ireland run parallel but distinct statutory regimes, so if your trees are in a devolved nation, check that nation's specific rules.
How to find out which type applies
Check the order document and its plan, which the LPA holds and usually publishes on a searchable register or interactive map. The order will state its classification. If it is unclear — particularly with an older Area order — ask the council's tree officer to confirm. Our Tree Preservation Order check guide walks through how to search, and if you are in a conservation area, remember that trees there can be protected even without a TPO through the separate six-week notice regime.
If you are planning development where any of these orders bite, you will likely need a BS5837 tree survey and an arboricultural impact assessment to support your application. For the full framework, read our main guide to Tree Preservation Orders.
