Mine is definitely subsiding. Unbeknown to me on purchase, but later told by a neighbour there was a big Plane Tree in front of our house that was removed by the council 2-3 years ago and there are also very large trees behind the house but are at least 10m away.
If you walk up the road every single bay window has cracked some more than others so I suspect there is also a water table issue at play. I'd welcome the house being underpinned. I suspect that under pinning will become more and more common as not only do houses age but get heavier as extensions go on upper floors. It might be seen as a positive in circa 10 years.
I wish my house had been underpinned
