What size cable would that result in for 60m 100A supply?
(Hint, I fell about laughing.)

One thing that has struck me, the OP is suggesting a 100A fused switch. No allowance for discrimination between a standard 100A service.

i have not suggested anything and have not done any work on this installation , just described the lay out of the existing installation which includes a switch fused 100amp isolator at the mains position.
the plot thickens.
i'm told there use to be a caravan were the new garage has been built .
found an enclosure with a consumer unit fed in 25mm SWA.
with no sign of the "Caravan supply " SWA at either end the bulder made a few calls and i was told there is an underground " tee joint " in the main SWA before the house !
anyone come across that before.
whipped the cover off the CU in the house for a quick look and has all the hall marks of a "Pub Job" ,just had a copy of the toilet paper /test sheets
box marked reg no reads "12345678 " .
due my inspection next month and jobs like this make you want tell em to shove there fee up the rusty rivet hole.
