What should I do if I suspect a tree is causing subsidence damage?
Trees close to buildings and other built structures can increase the risk of subsidence when roots extract moisture from shrinkable clay soils beneath foundation level. If you suspect that trees (council owned or on neighbouring private land) are causing subsidence to your property then it is important that you contact your home insurance provider. Your insurance company will look into your concerns and may want to investigate the damage as part of a claim. If they believe that a council or neighbours tree is implicated in the damage, they will contact the respective tree owners on your behalf.
Where a claim is made against a council owned tree the council will reasonably expect an appropriate level of evidence provided to demonstrate that the tree in question is an influencing cause in the subsidence. In the case of a preserved tree this evidence is mandatory. As a guide this information is likely to comprise the following:
Without this information it is unlikely that the council will be able to take an informed view on any proposed works or an appropriate solution.
