Just on the geology of the UK, we are also an island surrounded by water. Apart from recognising certain rock types that seem to enhance spiritual activity, water has also been observed and recognised by the paranormal community to play a part in the conducting of spiritual energies. We have many rivers, natural (and man-made) mineral springs, marshlands and canal ways here that have existed for decades.
As with many other places in Europe, we also have a relatively shallow water table - only between 3 and 10 meters down on average. This vastly differs to some places in the US, for example, where the water table sits at 250 meters below the surface. I believe this all contributes to the hauntings we get, alongside the other geology and historic elements.
