    Advice on trench

    Hello Just looking for some advice on a rough cost on having a trench dug for cabling in an ev charger. The run is only around 10 metres long and is a mixture of concrete tarmac and soft ground. From what I've read it should be 600mm and then the ducting in. Most recent quote was over £3000...

    Cable in concrete trench corroded

There was a long trench dug through the house, and the cables laid into it. Now, a few years on, I've had a qualified electrician confirm that the cables...

    Trench for outside light supply

    I'm quoting to install an outside light at some distance from the nearest building. About 16m of the run will be underground, mostly under lawn, with about 2m of that under paving slabs, which will have to be lifted and re-laid. I am proposing a 500mm deep trench with ducting and warning tape...

    Trench Depth for underground cable...

    Running a supply from the house to the garage, just about to dig the trench for the ducting but wondered what depth it has to be? The cable will cross underneath a slabbed path before going about 2 metres max across (under!) the garden.
