Their very long garden runs sideways along the back of ours and 2 other houses. Their play equipment is set about half way down the garden, so we'll away from their house but very close the our back fences.
Over lock down and through out the summer holidays the kids were in the garden 8am to 10/11pm on and off all day shouting and screaming really loudly. To the point where people on my conference calls could hear them over me speaking while I was working in the house. It really got me down but I tried to just put up as I realise lockdown was very tricky for lots of families.
We have never said anything because to be honest it sounds so petty to complain about children playing in their garden! Other neighbours did say something and it calmed down a bit and they seemed to be going inside earlier at night.
Last night at 10.40pm we were woken up by screaming and shouting again. It went on for about an hour. We could hear it clearly through double glazing. Nothing wrong, just children playing albeit ridiculously loudly! They are about 8-12 years old and there are 3 of them, plus frequent visitors.
As a parent, I can't understand why their parents think it is ok for them to regularly make this much noise. Why would you let your children do it? They must realise it is excessively loud and is disturbing people.
