Tree surveys for clear decisions
A tree survey records the condition of a tree or group of trees, explains the risks we can see and sets out the options. It helps homeowners, landowners and site managers decide what to do before any work is agreed.
What a survey is for
A survey is useful before a decision: before removing a tree, before pruning a crown that has grown over a boundary, when a tree looks unhealthy, or after a storm has left doubt about its stability. Buyers and sellers of land and property also sometimes need a written picture of the trees on the site.
A survey gives you a record. It does not replace the decision, but it makes the decision easier to explain to neighbours, a council or a contractor.
What the survey looks at
We record the species and approximate size of the tree, its visible health and any signs of decay, the structure of the trunk and main branches, and the ground and root area where these are visible. We also look at what the tree could affect if it failed or changed, such as buildings, paths, parked vehicles and people.
Reporting and recommendations
The report sets out what we observed, the level of risk we identified, the options, and the recommended actions with the reasons for them. It also states the limits of the inspection. Recommendations depend on what we find: a survey may suggest pruning, removal, monitoring or no work at all.
If the survey points to pruning, our tree pruning service explains the choices involved. If it finds that a tree cannot be made safe, the tree removal service covers how that work is planned.
What a survey cannot tell you
A survey is a visual assessment on the day of inspection. It cannot guarantee that a tree will never fail, and it cannot see decay hidden inside the trunk without further testing. Conditions change, so a tree assessed in summer may look different after a hard winter. The report will say what it is based on and when it was carried out.
Practical considerations
- Access: we need a safe route to the base of the tree and a clear view of the crown. Where the tree is in a neighbour's garden, their consent may be needed first.
- Protected trees: a survey does not confirm whether work is permitted. Check with your local planning authority first if the tree is protected.
- Timing: some decisions depend on the season, so tell us if you need the survey by a particular date.

Questions about tree surveys
Who will carry out the survey?
We will only describe a surveyor's qualifications once they are confirmed and supported.
Will the survey tell me what work to do?
It sets out the options and a recommended course, with the reasons. What you choose to do is your decision. Some recommendations may need permission before they can go ahead.
Can I get a survey for a single tree?
Yes. Tell us which tree it is, where it stands and what worries you, and we will explain what the survey will cover before you book it.
