We should be aware of any underground pipes and cables crossing our woodland. These will have been brought to our attention through searches when purchased.
Overhead.
First check to see if any overhead lines on or fronting your land are electricity or telephone.
Electricity lines. The regional transmission companies manage their overhead lines, in the Southeast it seems to be EDF Networks their main contact no. is: 0845 601 4516. http://www.edfenergy.com/products-services/networks/about-networks/index.shtml They will keep their lines clear but if you have a line with trees near or leaning on them phone and they will come and clear the lines. Obviously don’t touch a tree leaning on a power line, the cables have not insulation! Maintaining clear lines is their responsibility but they will ask permission when doing routine clearing. Make sure their contractors do a tidy job!
Telephone. BT look after their own lines, after a fashion. BT do not do routine clearing but take the view that if the lines are still up and have no faults then they are left to look after themselves weaving through the tree tops. If a tree falls on a telephone line causing a fault or wears through the insulation then they will send out their telephone engineers with a tree contractor and do the repairs and any tree clearing, all at their cost.
If you have a tree which, for some other reason, you want to fell next to a telephone line then contact BT and they will come and drop the line while you fell. To contact the relevant department take the numbers on the nearest poles, find the nearest phone number (to help them locate your site) and call faults. They will put you through to the relevant department.
Some roadside trees will be Highways responsibility. In 20 years we’ve never been asked to contribute to any line clearance!
