Is Your Tree Planted Too Close to Your House? A Guide for UK Homeowners.

Frequently Asked Questions

Can tree roots damage house foundations?

Tree roots can be associated with damage to buildings, but it is not as simple as roots physically pushing through foundations. In the UK, the main concern is often subsidence caused when trees take moisture from shrinkable clay soils, particularly during prolonged dry weather. Tree roots are generally unlikely to penetrate sound foundations directly, so the risk depends on factors such as the tree species, its size, soil type and the depth and construction of the property’s foundations.

How far should a tree be planted from a house in the UK?

There is no single distance that is suitable for every tree or property in the UK. The appropriate planting distance depends on the tree’s eventual height and spread, its root characteristics, water demand, soil conditions and the type of building nearby. Rather than relying on a fixed distance such as 15 feet, homeowners should consider the tree’s mature size and the conditions of the site before planting.

Which trees have the most invasive roots?

Some tree species have extensive or vigorous root systems and can present greater challenges when planted close to buildings, drains or other structures. Species with high water demand, including oak, poplar, willow and some eucalyptus and cypress species, can be particularly relevant where shrinkable clay soils are present. However, a tree should not be described as having “dangerous” or “invasive” roots simply because of its species, as the actual risk depends on the individual site and surrounding conditions.

Can I remove a tree that is too close to my house?

You may be able to remove a tree that is considered too close to your property, but you should check whether it is protected before carrying out any work. In England, a tree covered by a Tree Preservation Order normally requires written consent from the local planning authority before it is cut down, topped, lopped or uprooted. Trees in conservation areas can also have additional protection, so it is important to check with your local council before arranging tree work.

Can a tree cause subsidence?

Trees can contribute to subsidence in certain circumstances, particularly where they are growing close to buildings on shrinkable clay soils. During periods of prolonged dry weather, tree roots can take moisture from the soil beneath foundations, causing the clay to shrink and potentially contributing to movement of the building. However, not every tree near a property will cause subsidence, and other factors should be investigated before a tree is identified as the cause of structural movement.

Should I cut down a tree near my house?

Not necessarily. The presence of a tree close to a house does not automatically mean that it needs to be removed. The RHS recommends considering the tree’s species, size, condition, soil type and the construction of the building when assessing potential risks. If you are concerned about a mature tree near your property, having it inspected by a suitably qualified arborist can help determine whether pruning, monitoring or removal is actually necessary.

Who can inspect a tree near my property?

A qualified arborist or professional tree consultant can assess the condition, structure and potential risks associated with a tree. If you are concerned about suspected subsidence or cracks in your property, it may also be appropriate to involve a structural engineer or other building professional. Tree-related subsidence can be complicated, so it is important not to assume that a tree is responsible for cracks or movement without suitable investigation.

Can I move a tree that has already been planted?

Moving an established tree can sometimes be possible, but the difficulty and likelihood of success depend on the tree’s species, size, age and health. Smaller and younger trees are generally easier to transplant than large established specimens. Moving a mature tree can cause significant root disturbance and stress, so professional advice should be obtained before attempting to relocate it.

What should I do if I notice cracks in my house near a tree?

Cracks in a property should not automatically be blamed on nearby trees, as there can be many possible causes of cracking and movement. If you notice new or worsening cracks, particularly around windows, doors or other parts of the building, it is sensible to have the issue properly assessed. Where a nearby tree is suspected, an arborist and, where appropriate, a structural engineer can help establish whether the tree is contributing to the problem.

Do I need permission to prune a tree near my house?

You may need permission depending on the tree’s legal protection and where your property is located. In England, trees protected by a Tree Preservation Order generally require consent from the local planning authority before certain work is carried out. Trees in conservation areas can also be subject to controls. Always check with your local council before arranging significant pruning or removal, particularly if you are unsure whether the tree is protected.
