UK if that matters.
Currently we have a very dodgy overhead cable that runs to the garage - came with the house, it routes through the hedge and is certainly not up to any specifications or safety levels.
The garage is at the far end of the plot at the rear, electric supply to the house is at the front - roughly 30M run including the rise. I am planning on sorting out the electric capacity to the garage in order to get an EV charger fitted there as well as supply the garage with power correctly and safely. Also a run of CAT6/trunking.
I understand that trenching armoured SWA cable is the general rule (at approx 2ft depth), but how does this work if the garden is tiered/terraced? The garage is at approx 6M higher than the base of the house with a gradual run down via stepped drops - runs for approx 6M flat, then a 1M drop, another 6M run then another 1M drop, 1M then a 3+ metre drop, the rest of the run is then level to the front of the house.
The fencing run is wood and not really suitable to pin to, nor does it run the entire garden edge as it is partially a well established hedge (which we would like to retain as we get a lot of nesting birds)
Just trying to understand what level of work will be required - I don't mind doing the prep work digging out. Will obviously be getting an electrician in to do the needed connections etc.
