I didnt go to the dentist for three years and as i have a bit of a sweet tooth this is not recomended! Woke up in the middle of the night with massive pain, went to the dentist and found i had an abscess and a whole host of fillings that needed doing. My dentist had gone private in the meantime...
Rented 2 different houses in 2 years in Portsmouth and never came across this, although the first year the agent charged us £120 for their 'services'. Second year they were far more proffesional and didnt charge us a penny.
I always need to piss at night and its really irritating, preventing me from nodding off, consequently i always make sure my bladders dryer than the Sahara before bed.
I can imagine particulary along the west coastway that doing night time works will piss off large numbers of residents. Whatever time you do it though you will piss people off.
