You need an Ordnance Survey map (scale 1:2500-1:10560) showing the location of your site and detailed site plan (scale 1:100-1:500) showing the layout of any new or existing buildings. Mark the exact location of the line or pole to be moved with a red pen. Photocopies are accepted.
Note: In cases where the work you are doing requires planning permission, you must provide details of the permission.
