Fence Panels

[Theblip]

Is there a legal height limit on garden fence panels in the UK?

2m I think

[Atheist]

Planning permission not usually required for a fence or wall not fronting a highway, providing it does not exceed 2m in height. If fronting a highway, the max height is 1m.
If the fence is out of sight and no neighbours are likely to object, you might consider gently exceeding the height. Local Planning Authority should be contacted in case of doubt; e.g. if you have a Listed Building or are not sure about anything. There are other govt sources for such information, referring to Permitted Development.

2 m should be enough if you want to put something up, will be 6' 6 " once gravel board is in.

Tony, 2m is 6 foot six. Gravel board is irrelevant; it's overall height that counts. Typical panel will be 6 foot (1.8m) plus 20cm gravel board gives 2m.
Hope the OP gets the gist. Go for it if you're not asking for trouble by riiculous height or nasty neighbours. LPA won't launch an expensive enforcement procedure if there is no significant harm arising.

For all we know, Atheist, Theblip might actually be the nasty neighbour, wanting to challenge the height of a fence erected by the guy next door ;-)

Buen I think my advice is still relevant. If theblip is the 'nasty neighbour' then it's sensible that he knows the parameters. Trying to thwart a neighbour by quoting the letter of the law will not necessarily result in a 'victory'. A small infringement of the letter of the law will not result in draconian action against the infringer unless there would be significant and demonstrable harm to interests of acknowledged importance e.g. neighbouring amenity, or the character and appearance of the local area, or highway safety, or badger or bat welfare...... and so on.
