Tree Surveys & BS5837 Reports in South Downs

Do you need a tree survey in South Downs?

If your project could affect a tree — one on your land, on a neighbour's, or on the street — within roughly its own height of the works, South Downs will usually expect a BS5837 tree survey before it will validate the application. It's near-certain where a tree is covered by a Tree Preservation Order or stands in a conservation area — check whether a tree is protected before you plan any works.

Requirements are set locally, so the exact trigger varies between authorities. Like every English planning authority, South Downs works from a local validation checklist, and where trees are affected an application submitted without the arboricultural information is usually invalidated — held before it's even assessed — rather than refused. That's a delay you avoid by getting the survey done up front.

What the survey leads to

The survey grades each tree A–U and calculates its root protection area — the ground you must keep clear. It then feeds an Arboricultural Impact Assessment setting out what your design means for the trees. If South Downs grants permission, you'll commonly need a Tree Protection Plan and an Arboricultural Method Statement approved to discharge a pre-commencement condition before any work starts on site. Budget for it early — see typical tree survey costs.
