In England and Wales a mains-fed sprinkler counts as a hosepipe where that supplier’s temporary use ban is in force, under the Water Industry Act 1991 section 76 and the Water Use (Temporary Bans) Order 2010. A lawn counts as a garden. The offence is a fine up to level 3 on the standard scale. It is not a UK-wide switch. As of 20 October 2026, Thames, Anglian, Essex & Suffolk, and South East Water in Sussex had bans in force. Scotland and Northern Ireland use their own drought powers. Use a can, or rainwater already in a butt, and do not fill the butt from the mains during the ban.
