Catenary wire

[diditrain]

I have been asked to install a catenary wire to take a supply into a detatched outhouse.
The span is roughly 6 metres and at the rear of the property. The span will cross an area, which the residents use to park their vehicles. 709.521.1.8 BRB says that overhead conductors should be installed at a height above ground of not less than 6 metres in all areas subjected to vehicle movement.
The house is a mid terrace and is not very tall. If i was to conform to this height then i would have to take my catenary above the gutter height on some sort of extension pole. Don`t faancy doing this as i think that it will look awful.
What would others do in this situation? It is roughly 4 metres to gutter height. My thoughts are to take it to gutter height

I think you'll find that the vehicle movement is referring to traffic other than cars, to cater for the passage of emergency vehicles. I think the general guidance elsewhere is 3.5M (I don't have my regs book to hand to look it up).

In positions accessible to vehicular traffic, the lowest part of your catenary would need to be 5.8m above the road surface.
In positions inaccessible to vehicular traffic, the lowest part of the catenary would need to be 3.5m above ground level.
See GN1 Appendix G for guidance.
However if the car parking is off the public highway, you maybe able use a bit of common sense and say >3.5m is adequate in your circumstances, providing it will not impede emergency service vehicles or other authorities requiring rear access to the buildings or surrounding area.
If it is a metalled road and considered part of the public highway you will need approval from the local highways authority to run an overhead line, as warning signs e.t.c. maybe required. If it's a private road approval by the land owner is all that is required.
