Many years ago I assisted with a thatched cottage full rewire, although calling it a cottage seems far too understated.
We had to work to a spec from the insurance company which was basically:
All wiring throughout the property had to be in threaded steel conduit or Kopex, the older type with corrugated metal lining, paper and PVC sheath.
Minimum conductor sizes for the MCB rating - essentially meaning wiring was 2 sizes bigger than regs/calculations.
No fuses in CU or lofts.
No junctions in lofts.
No downlighters (before the days of LED).
Firestopping holes.
I'm sure I've missed some.
