Electricity Cable On A Boundary Wall

[Jaspar1969]

Hi
I live in a terraced house and my consumer unit is in the middle of my house. Which is an extension. If the neighbour allows can I run armoured cable out from the back of the unit and along the outside wall which is in his garden and then drop back into my own garden at the end of the ‘boundary’ wall?

There's really no reason why you shouldn't attach a cable to your own property.
The only consideration is that you have your neighbours permission to go into his garden to do the job.

Bear in mind that terminating armoured cable properly is quite a tricky job. A qualified electrician would be your best option.
Also, depending on what it's for, it may well be notifiable for "Building Regulations."

I second Builder's comment that terminating armoured cable is a tricky job. I ran a supply from the house to my shed and it was tricky - needed a hacksaw to get through the armour - but I did manage to do it.

Haha. Quite right Atheist. It's a horrible job to make it neat.
If you watch any of the Youtubes of it, they make it look so easy. :o)

Thanks for the answers. I will be getting an electrician to do this - just wanted to know if you think I’m allowed to run a cable on my wall in neighbours garden. Obviously would ask permission just to be courteous.

Is your wall literally right on the boundary, so that the cable would be in the neighbour's garden?

[Jaspar1969]

Yes. The extension is the boundary.

Would it not be possible to run the cable on the inside of the wall, until it reaches the wall that runs at 90 degrees to this wall. Your cable can then go through this wall and straight out onto your land.

[Jaspar1969]

Not really - I would have to run conduit/ trunking through the hall and kitchen to get to the back garden.
The supply is for a garden building at the bottom of the garden.

Could you do as Giz says ..you could run within the building fabric using pvc/pvc flat twin cable to cut out the neighbours bit..and then transition to swa to complete the external bit. Running the swa along the neighbours side could throw up issues in the future when periodic inspection reports are carried out especially if access to the cable is restricted.

I think I'd go with Ryzens' approach.
