Council & Housing Tree Stock Surveys

Overview

Managing tree stocks at scale

Local authorities and registered housing providers carry a significant duty of care over the trees within their ownership. Failing to maintain an accurate, up-to-date record of tree condition and risk exposure can result in liability, reputational damage and preventable harm to residents and the public.

UA-5 delivers systematic tree stock surveys and ongoing cyclical inspection programmes tailored to the needs of asset managers, estates teams and tree officers. Every survey is conducted by Lantra-qualified inspectors using structured PTI methodology and digital field capture, producing a live, GIS-compatible dataset that supports decision-making and procurement planning from day one.

What we deliver

Full tree stock surveys across housing estates, parks, highways verges and open spaces
Individual tree records: species, age class, height, spread, condition and risk rating
Photographic evidence and GPS coordinates for every tree
TPO and conservation area identification flagged at survey stage
Recommended management actions with priority classification
Cyclical re-inspection scheduling aligned to risk profile
GIS-compatible data output compatible with your asset management system
Works specification and procurement support
Summary reporting for estates, asset management and senior stakeholder use

Why It Matters

Duty of care and liability management

Local authorities and housing providers are exposed to significant legal risk from unmanaged tree stocks. A structured survey programme is the foundation of any defensible tree management regime.

Defensible Compliance

A documented, systematic inspection programme provides clear evidence of due diligence in the event of a claim or regulatory review. Ad hoc or reactive-only management does not.

Risk Prioritisation

Not all trees carry equal risk. UA-5 survey outputs classify each tree by risk category so maintenance budgets can be directed where they matter most, rather than spread uniformly.

Asset Data You Can Use

Survey data is delivered in formats compatible with standard asset management and GIS platforms, enabling integration with your existing systems rather than sitting in a standalone report.

Housing Estate Specialists

We understand the operational environment of housing associations and local authority estates — including communal areas, boundary disputes, resident sensitivities and restricted access arrangements.

Cyclical Programmes

One-off surveys provide a baseline. Ongoing cyclical inspection programmes — typically on 1, 2 or 3-year cycles depending on risk rating — ensure the register remains current and your liability position stays managed.

Works Specification

Where works are required, UA-5 can produce a fully costed, prioritised works specification suitable for direct procurement or tender, drawing directly from the survey dataset.

Our Approach

Survey methodology and data standards

All tree stock surveys are conducted using the Lantra Professional Tree Inspection (PTI) methodology as the baseline assessment framework. Field data is captured digitally on-site, geo-referenced and attributed to enable immediate GIS import and filtering.

Each tree record includes species, estimated age class, height band, crown spread, stem diameter, overall condition, observed defects, failure potential assessment, and a recommended management action. Risk ratings follow a consistent classification allowing direct comparison across sites and across inspection cycles.

TPO, conservation area and other statutory designations are identified and flagged at the point of survey, ensuring your asset data reflects legal constraints from the outset rather than requiring a secondary check.

Typical survey outputs include

Individual tree records with full PTI attributes

GIS shapefile or CSV export

Photographic log referenced to tree ID

Risk register with priority classifications

TPO and statutory designation flags

Management action schedule by priority

Executive summary report for senior stakeholders
