Two of the three wouldn't bother with a CU in the shed, opting for a beefy fused spur (like you get for cookers),
That’s what I’d envisioned as a workaround, but it’s not ideal in my eyes. Can’t say for sure if it’d need an earth rod - that’s down to what your Zs readings are (making sure the resistance of the circuit in an earth fault condition is low enough to trip the breaker within the required time - more resistance = slower trip time).

Thanks. I am going by three electrician quotes I have already had. Two of the three wouldn't bother with a CU in the shed, opting for a beefy fused spur (like you get for cookers), and no one was willing to bury the cable, saying they'd pass it on the floor behind some planters. One of the three said they'd install a ground spike and a CU.
Even if it takes more than a day, 2 grand is crazy money.
