Is your hot tub installed in a “holiday let” setting?

According to Health and Safety Guidelines (HSG282), a domestic hot tub used in rented accommodations—including holiday lets, homes, parks, lodges, chalets, cottages, and caravans—should be disinfected using Bromine or Chlorine through an inline continuous disinfection feeder.
