After 5 months of sleep deprived nights, and four letters to the care home asking for help, I discovered I had a way through EH to deal with the matter. Within 2 weeks of EH being involved, the care home were served with a formal abate order, and within 3 weeks, the care home fitted a silencer to the tumble drier (the offending device).
If the Care Home had simply listened to my complaint, first given in Oct 2013, this would have been avoided.
However, no doubt that 5 months of sleepless nights, and day time tension have taken there toll, and I believe the Care Home are due to pay compensation. As yet they even have not had the courtesy to apologise.
