Tree preservation orders exist across the whole UK, but Scotland, Wales and Northern Ireland each run them under their own devolved legislation — the protection principle is the same, the statute behind it is not.
Most tree-preservation guidance online is written for England, under the Town and Country Planning Act 1990 and the Town and Country Planning (Tree Preservation) (England) Regulations 2012. If your site is in Scotland, Wales or Northern Ireland, that guidance is close but not authoritative — the regulation numbers, notice periods, forms and appeal routes are different, and citing the wrong ones is how people get caught out. Here is how each nation actually works, and where the differences bite.
The one thing that is the same everywhere: BS5837
Before the differences, the common ground. BS 5837:2012 is a British Standard and applies UK-wide. A tree survey, tree constraints plan, arboricultural impact assessment, tree protection plan and method statement mean the same thing in Glasgow as in Guildford. The technical machinery is identical: every tree is graded into categories A, B, C or U (there is no "Category R" — that is a legacy misconception), and the root protection area is calculated the same way everywhere — a radius of 12 times the stem diameter measured at 1.5m, capped at 707m².
And everywhere in the UK, BS5837 is guidance, not law. It only becomes compulsory when the local planning authority demands it through its validation list or attaches it as a planning condition. So the BS5837 survey and the RPA calculation you produce are fully portable across the four nations. What changes is the statutory tree-protection regime sitting alongside the planning application.

Scotland
Scotland is the most clearly separate. Tree preservation orders are made under the Town and Country Planning (Scotland) Act 1997, with the operational detail in Scotland's own tree-preservation regulations. The planning authority makes and administers the order.
The core prohibition mirrors England: you must have the authority's written consent before you cut down, top, lop, uproot or wilfully damage or destroy a protected tree, and that expressly includes cutting roots — the kind of damage that happens accidentally when a driveway or extension is excavated too close to a tree. Conservation-area trees are separately protected under a notice regime. Scotland also runs felling permissions through Scottish Forestry rather than the Forestry Commission, a distinct regime that can apply to larger-scale felling outside gardens.
Because the legislation, forms, consent periods and appeal routes are Scottish, always apply to the relevant Scottish council and check the individual order's schedule rather than relying on English timescales. Do not assume the 8-week determination period or 2-year consent validity you may have read for England transfers unchanged.
Wales
Wales is the closest to England because it shares the same primary Act — the Town and Country Planning Act 1990 covers England and Wales together. However, Wales made its own Town and Country Planning (Tree Preservation Order and Trees in Conservation Areas) (Wales) Regulations 2012, so the operational rules are Welsh.
For most applicants the practical experience is very similar to England: a protected tree needs written consent for works; conservation-area trees carry a six-week notice regime; and the standard exemptions (dead trees, urgent danger works) broadly apply. But the governing regulations are the Welsh ones, enforcement and validation practice sit with Welsh councils, and felling licences are issued by Natural Resources Wales. Treat "England guidance" as a useful indicator, not the rulebook, and confirm anything time-sensitive against the Welsh regulations.
Northern Ireland
Northern Ireland is the biggest departure. Tree protection sits under the Planning Act (Northern Ireland) 2011, a wholly separate planning statute with its own regulations. Since the 2015 reform of local government, district councils make and administer tree preservation orders and deal with conservation-area tree matters — a change from the earlier centralised departmental arrangement, so older guidance that points you at a central department is out of date.
The protective principle holds — written consent before works to a protected tree — but the forms, timescales, appeal routes and conservation-area procedures are Northern Irish. English regulation numbers and consent periods do not transfer. Deal directly with the relevant district council's planning service from the outset.
A worked scenario
Say you own a semi in a conservation area near the England–Wales border and want a rear extension close to a mature oak. In England, if the tree is not already covered by a TPO you would give the council a section 211 conservation-area notice six weeks before any works, giving the authority a window to make a TPO. Just over the border in Wales, the same works are governed by the Welsh 2012 Regulations — the six-week notice principle is similar, but you file under Welsh procedure with a Welsh council. In Scotland or Northern Ireland the conservation-area procedure is defined by entirely separate legislation. In every case the BS5837 survey you commission to support the home extension is the same document — it is only the statutory notice wrapped around it that changes by nation.
Requirements are set locally — check your council
Even within a single nation, the validation requirement for arboricultural information is set by each local planning authority, not by central government. Two neighbouring councils can word their trigger differently, demand different documents at validation, or run very different tree-officer expectations. The national statute tells you how protection works; the local authority tells you what to submit and when.
That is why the practical first step, wherever you are, is to check the specific authority. PlanWatch tracks live tree-related planning activity council by council, so you can see how TPO applications, conservation-area notices and tree conditions are actually handled in your area. Browse the tree surveys hub, or look at how activity differs across authorities such as Leeds, Bristol and Manchester to get a feel for how much local practice varies before you rely on any national summary.
Practical takeaways
- BS5837 travels; the statutory regime does not. Your survey, RPA work and A/B/C/U grading are UK-wide; your TPO and conservation-area obligations are nation-specific.
- Always check the specific order and the local authority. Every TPO has its own schedule listing exactly which trees are protected. Do a TPO check with the right authority before assuming a tree is or isn't covered.
- Don't import England's exemptions. The "dead tree" and urgent-danger exemptions exist across the nations, but the exact wording, notice periods and size thresholds are set by each nation's regulations — confirm before touching a tree.
- Felling licences are a fourth regime. Beyond planning and TPO consent, larger-scale felling outside gardens may need a licence from the nation's forestry body — a separate application entirely.
- Consent is separate from planning permission everywhere. In all four nations, holding planning permission does not, by itself, authorise works to a protected tree. That trap catches homeowners UK-wide.
