    Our chimney stack is in a bad state of repair externally, cracked render, moss growing in amongst spalled brickwork etc etc. We need to get it repaired. Problem is, the chimney has a wrap around metal band with three insulators where the electricity supply is fed to the house, and from which the primary mains cable runs down to our fuse box.

    I don't think there's any way to fix the stack without temporarily detaching the wrap around metal band and therefore the three hefty electricity cables. Would this therefore be a job for the power company, or can a spark handle it?

    If it's a job for the leccy company, how much does that kind of thing cost? I wouldn't mind rerouting the supply anyway - at the moment the overhead cables run right over our lawn and spoil the view!

    Thanks for any advice and info on likely costs.

    As it is before the meter it may well be their responsibility, especially if it is unsafe.
  1.  
    I had oversailing cables at my last house and received wayleave payments from the power company. I put a propane tank in the garden and because the cables were uninsulated they replaced the three cables with a single insulated aerial bundled cable. At my present house because the cables oversailed the garden and were in the way of my newbuild house they moved a couple of poles so the cables ran along over the boundary and didn't oversail. Both times the work was done free of charge. I don't know if that helps at all.

    Up to the meter it is power co responsibility if the fixing is unsafe then supply company responsible.Doing my own refurb I had my existing overhead cable moved underground. I had to dig the trench and lay the conduit at my expense. Scottish Power ran a new supply cable from the pole in the garden approx. 45 mts and charged me £800 that was about 2 years ago. Looks like Peter was fortunate.

    Thanks folks. Revor I think I'd like to do the same as you. How deep was your trench and what conduit do you have to put in?

    Same as revor ... moved from overhead to undergound. We dug the trench, and miraculously we only paid SSE £132+VAT for a reconnection ... although before that we did get charged £340+VAT by the same people to disconnect a 2nd supply ... and that was about 12 minutes work I think.

    Mitchino, Think trench was about 600 deep but check with your supplier, I used 50 mm civils conduit pipe but watch out for 90 deg bends if needed use 2x 45 deg to make a slow bend. Alternatively you could use 80 mm Nayor conduit pipe looks like land drainage pipe but without perforations. Use this if you have a long run or the supply cable is greater than 16 mm as installers may struggle to pull the cable through. Needs bedding in sand then put a warning tape approx 300 mm above the ducting so if someone comes along with a digger In the future they will find the tape before the cable. Don't forget to put a rope through the ducting 6mm blue propylene should be ok.

    Speak to your local network company - ours was Northern Powergrid. They specified what they wanted if we were to do the conduit ourselves and where very specific about what we could have...

    When I laid the conduit for my newbuild, UK Power Networks wanted a specific conduit and the only supplier I could find was Jewsons. I also had to use hockey sticks at each end. They also wanted a draw cord fitted. The BCO also wanted to see warning tape on top of the conduit and another layer 300mm above the first. I've yet to find out how much it is going to cost me to have the cable installed.

    Ditto. and the draw rope should be at least 6mm poly. The draw cord that is sometimes supplied in the pipe may not be strong enough. Use it to pull a fatter cord through before burying the pipe.

    Scottish Power Network supplied the conduit and cable. They may move it for free if it is unsafe. I'd ring up and say you think you have an unsafe supply and they will be round faster than a weasel up a trouser leg.

    edit - I wonder if you could go so far as to say the damage has been caused by the cable movement...... You are happy to fix the chimney but they will have to move the supply.....
