As a landlord in the UK, your to-do list is likely dominated by gas safety certificates, electrical inspections, and tenancy agreements. However, one of the most overlooked aspects of property management lies just outside the window: the garden.

While a mature oak or a row of poplars can add significant “kerb appeal” and value to your rental property, they also carry significant legal and financial responsibilities. In the UK, the “Duty of Care” regarding trees is clear, and ignorance is rarely accepted as a defence in court.

Here is why regular tree inspections should be a non-negotiable part of your property maintenance schedule.

1. Legal Liability and the Duty of Care

Under the Occupiers’ Liability Act 1957 and 1984, landlords have a legal duty to ensure that visitors (including tenants and the general public) are reasonably safe. If a tree or a branch falls and causes injury or property damage, the owner is liable if it can be proven that the tree was hazardous and that a “reasonable” inspection would have identified the risk.

Regular inspections by a qualified arborist provide a paper trail. This documentation proves that you have been proactive in managing risks, which is essential if you ever need to defend a personal injury claim.

2. Preventing “Actionable Nuisance”

In UK law, if a tree on your property causes damage to a neighbour’s property (such as roots lifting their paving stones or branches damaging their roof), it is classified as a legal nuisance.

Landlords are often held responsible for “encroaching” roots or branches. Regular inspections allow you to:

• Identify roots that may be interfering with drainage systems or foundations.

• Prune back overhanging branches before a neighbour makes a formal complaint.

• Maintain good relations with the local community and avoid costly boundary disputes.

3. Protecting the Property Structure

Trees and buildings in the UK have a complex relationship, particularly in areas with heavy clay soil (common in London and the South East).

• Subsidence: Large trees can draw significant amounts of moisture from the soil, causing it to shrink and leading to structural cracks in the house.

• Direct Damage: Heavy limbs overhanging a roof can damage tiles during a storm or clog gutters with leaf litter, leading to damp issues inside the property.

An inspection can identify “high-water-demand” trees that may need more frequent crown reduction to keep the property’s foundations stable.

4. Identifying Pests and Diseases

The UK is currently facing several tree-health crises, including Ash Dieback and the Oak Processionary Moth.

• Ash Dieback: This fungus makes trees brittle and prone to sudden limb failure.

• Safety Risks: Some pests, like the hairs of the Oak Processionary Moth caterpillar, are a genuine health hazard to tenants and pets.

Early detection through an annual or biennial inspection can save a tree through targeted treatment, or at the very least, allow for a controlled removal before the tree becomes a dangerous “standing dead” hazard.

5. Compliance with TPOs and Conservation Areas

Before you pick up the saw, you must know the status of your trees. Many trees in the UK are protected by Tree Preservation Orders (TPOs) or are located within Conservation Areas.

Working on these trees without permission from the Local Planning Authority can result in fines of up to £20,000 per tree. A professional inspector will check the legal status of your trees and handle the necessary applications for works on your behalf.

Summary: A Proactive Approach

For a landlord, a tree inspection isn’t just an extra cost—it is an insurance policy. It protects your tenants, your neighbours, your bank balance, and your reputation.
