i've just put up a 6 ft fence, with 1ft trellis on top - total height = 7 ft...
never bothered with planning permission - i mean its just a fence...

just found this:
In general, if the height of any fence or other ‘means of enclosure’ (including a gate or wall) is within 20 metres of a road and would exceed one metre in height, then planning permission is required.
‘Road’ includes footpaths, tracks etc (see Roads Scotland) Act 1984 for definition).
In any other case where the height of the ‘means of enclosure’ would exceed two metres, then planning permission would be required.
Planning permission is required for any fencing within the curtilage of or surrounding a listed building.
Hedges do not require planning permission.
so maybe i'll just keep quiet...
