There have been a few other threads recently about noisy neighbours. With people home more I guess a certain amount of extra noise is inevitable but that doesn’t make it any easier to tolerate.
I really feel for all of those suffering in this way.
I think it’s always best to try to sort it amicably if possible.
Have you tried calling round to politely explain the problem ?
Are they otherwise reasonable people?
It may well be that they have no idea how much the sound travels, and if you explain how it is keeping you awake at night, that might be enough to do the trick.
Otherwise there is Environmental Health, but it’s surely worth a try to appeal to them directly first.
