Hi there I read your message, and the other posts on here about this, and really feel for you Lee. It's your home, your private space, and you're having it regularly and thoughtlessly interrupted and ruined by your neighbour's behaviour. A few years ago I moved house and area because of my neighbour's aggressive behaviour, shouting and swearing (often directed at me - I stood it for seven years and then sold up and came to Dulwich). So I'm hugely sympathetic. The ideal is the noise stopping or Southwark Council acting, and from the sounds of it this will remain in 'ideal' territory i.e. it won't happen, or there'll be even more conflict with your neighbour. After a while, as much as one hates it, one has to go with the realities. So my suggestion is, and you may not like it, but the priority has to be you and your peace of mind... can't you offer to erect the layer or barrier you mentioned on their fence? Some kind of noise-abating substance, I think you called it an 'acoustic baffle', so even if they do kick the ball, the sound is softer and more muffled? Or, if as you say it isn't expensive, offer them half the money to do this? I know this isn't right, and they 'should' stop or do this themselves but if they won't, then this could be the compromise. Not ideal - I appreciate that - but anything to get rid of the sound of that blasted kicking, right? I hope this is helpful - you have my best wishes for a speedy resolution.
