If trees sit on or near your site in Merseyside, 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 Merseyside, tree constraints most often shape planning outcomes within urban regeneration and established residential areas.
This commonly includes:
Residential districts, where mature street and garden trees constrain extensions
Brownfield and regeneration sites, where retained planting influences layout and public realm
Transport corridors, where tree belts affect access and alignment
Smaller urban plots, where root protection areas limit buildable area
Local planning authorities expect tree impacts to be addressed early rather than deferred.
We provide Tree Surveys for Planning across Liverpool, St Helens, Wirral and surrounding settlements, supporting residential and commercial development throughout Merseyside.
Merseyside 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.
Our Tree Surveys for Planning are commercially aware, proportionate and planning-led, designed to support real-world construction sequencing, access logistics and foundation strategy without unnecessary escalation.
A planning-focused output that Merseyside planners can rely on:
BS 5837 tree survey and constraint data
Root protection area calculations and crown spread mapping
Retention categorisation with management commentary
Clear, decision-ready planning summary

A BS 5837 tree survey may be needed where trees are present on or close to a proposed development site in Merseyside. This can include residential extensions, infill developments, commercial schemes, redevelopment projects, and changes to access arrangements. The survey identifies tree constraints early so they can be incorporated into the design before a planning application is submitted.
A BS 5837 tree survey assesses the species, height, stem diameter, canopy spread, age class, condition, and retention category of relevant trees. It also calculates Root Protection Areas (RPAs) and identifies constraints that may affect site layout, building positions, foundations, drainage, utilities, access routes, and construction activities.
Yes. Street trees can affect a planning application if their canopies or Root Protection Areas extend into the proposed development area. Even though these trees are often outside the site boundary, they may still influence excavation works, access arrangements, drainage design, and construction methods.
Undertaking a tree survey before detailed plans are prepared allows tree constraints to inform the design process from the outset. This can reduce the risk of redesign, planning delays, and additional costs by ensuring that important trees and Root Protection Areas are considered before layouts are finalised.
A Root Protection Area is the minimum area around a tree that should remain protected to maintain its health and structural stability. BS 5837 surveys calculate RPAs for retained trees and show them on plans so development proposals can be designed to avoid unnecessary impacts on root systems.
Yes. Trees on neighbouring land may need to be included where they could influence the proposed development. Their canopies or Root Protection Areas may extend into the site, making them relevant to foundation design, excavation works, access routes, and construction activities.
Yes. Trees protected by a Tree Preservation Order (TPO) or located within a Conservation Area can significantly affect development proposals. A BS 5837 survey helps identify protected trees and assess how the development may affect them, helping applicants address tree related constraints at an early stage.
Requirements vary depending on whether the site falls within Liverpool, Knowsley, Sefton, St Helens, or Wirral. Liverpool City Council provides planning guidance here: https://liverpool.gov.uk/planning-and-building-control/planning-applications/. Applicants should review the validation requirements of the relevant local planning authority before submitting an application.
Yes. Providing arboricultural information at an early stage helps planning officers assess the impact of development on existing trees. This can reduce requests for additional information, support smoother validation, and minimise delays during the planning determination process.
Depending on the proposal, additional documents may include a Tree Constraints Plan, Arboricultural Impact Assessment (AIA), Tree Protection Plan (TPP), and Arboricultural Method Statement (AMS). These documents explain how trees influence the development and set out the measures required to protect retained trees before, during, and after construction.
