Have had the report back, tree is a 17m mature lime. Despite difference in levels it’s anticipated that the roots will have gone under the house and have been for decades without issue. Soil is low in clay but a 1 to 2m crown reduction is advised.
Potential fly in the ointment is an ‘element of included bark’ at a 3m high bifurcation along with crack developing below the union. Further investigation needed.
Waiting for a call on the costs of a second inspection. Also found out the tree has a tpo attached.
