Don't want to worry you benji but had similar a while back. Barn conversion with vaulted ceilings, and no roof space or floor voids. All ground floor power buried in screed. After breaking down two rings not one cable had an acceptable IR, most were around 0.1-0.2 megs. The whole of the ground floor power had to be rewired in surface trunking.

There is a lot of t&e,in this old realm,buried and encased,in materials not conducive with longevity

Sometimes it survives longer than it should,and sometimes...
