Thanks @TheMinkey Yes we did start with the diary but it became almost a full-time job updating it. To be honest, roughly 4 months in, since around the start of June - the contractors started adhering to the time regulations at least on Monday-Friday. It has now become less about calling the noise team and more just keeping the windows closed except for a brief respite in the evenings and on Sundays. The last time we called the noise team was on a Saturday late afternoon and they asked us to stay in the house while they sent a team out to investigate. The team then failed to show up. We lost yet another day to sitting in the house, listening to drilling and it turned out the complaint had been mis-managed(?) and was followed up with a phone call and apology. We try and get far away from the house on Saturdays now- nothing worse than attempting to have a lie in or sit and eat breakfast to a soundtrack of hammering, drilling, digging, shouting.
