Do you need a Tree Survey for Planning in London?
If trees sit on or near your site in London, your planning application is highly likely to require a BS 5837 Tree Survey. Root protection areas, crown spread, access positioning and tree quality all influence whether a layout is acceptable. Without early arboricultural evidence, even small schemes can trigger validation delays, redesign requests or restrictive conditions.
We confirm what’s required quickly and proportionately so your application stays on track.
Across London, tree constraints most often affect planning where development occurs within dense urban settings and established neighbourhoods.
This commonly includes:
Residential streets with mature street trees, where extensions and basements are constrained
Infill and redevelopment sites, where retained trees shape layout and public realm
Transport-led schemes, where tree belts influence access and alignment
Tight urban plots, where root protection areas significantly affect buildable footprint
London boroughs expect tree constraints to be fully addressed at design stage.
We deliver Tree Surveys for Planning across all London boroughs, supporting residential and commercial development throughout Greater London.
Why Planning Authorities Require a Tree Survey in London
London planning authorities rely on clear arboricultural evidence to assess whether development layouts properly respond to existing trees. Trees are a material planning consideration under the Town and Country Planning Act 1990, with national policy reinforced through the NPPF and technical requirements set out in BS 5837 (Trees in relation to design, demolition and construction). Where proposals affect root protection areas, canopy spread or retained tree quality, planners must be satisfied that designs are feasible, proportionate and deliverable.
When arboricultural evidence is unclear or incomplete, applications are commonly delayed, conditioned or returned for revision.
