Strange one but I wonder if anyone can give any help? I obviously play a musical instrument and I know that it can be loud at times but I am careful not to practice beyond 9pm because of our neighbours. Now on a totally different level, the house next door is being renovated and they've got some chaps in there who although seem very good, cannot speak a word of English and carry on working twith thier sanders, drills and hammers until sometimes gone 2am. I tried to speak to them to ask them what time they intended to finish that night but they just looked at me blankly and started speaking what I can only imagine was some type of arabic dialect. The boss chap never seems to be around anymore, having been for the first 2 months, when he was they'd pack up and leave at 5pm! They've applied for planning permission to build a 2 storey extension and whilst we hre more than happy for them to do this, as we'd like to do the same, we are concerned the building work will proceed on til the same amount of hours. What are the rules on noise levels and time noise should stop, I can't find any details with our local council, can anyone help?
