According to the local council:
"All DIY/Construction noise must be carried out during the hours of
8.00am to 5.00pm Monday to Friday and 9.00am till 1.00pm on Saturdays and none at all on Sundays."The rules regarding construction noise would make sense for businesses such as builders, sparkies, plumbers and carpenters/joiners etc.
When pressed on the point of homeowners doing DIY at weekends and early evenings:
According to the council, wallpapering or painting can be done at *any* time, even through the night, but power tools must only be used during the times stated above.
That seems incongruent with DIY hobbyists who work a 9 to 5 Mon to Fri job, How are they supposed to carry out DIY with such restrictions?
Personally I would have thought till 7.00pm weekdays for noisy activities would have been OK and that all day on Saturday and Sundays from 9am to 5pm.
Incidentally, the use of lawnmowers in summer evenings is OK as no one has ever complained about a lawnmower in over 20 years!
