Looking to run either a spur or full ring from my house to my shed. The cable would need to run down an internal stair, then underground for approx 8m.

The labouring, for lifting slabs & digging trenches can be arranged. I need some advice on how to prep' that before you start the work.

I would prefer a full ring, but I'm assuming this would involve running a cable from the front of the house, right out the back, which may not be advisable or possible.

The consumption would not be huge. But it would be good to run a power tool AND a light at the same time - but that's why I need advice before the process starts.

Thanks.
