Isle of Wight is served by 1 water company, and a ban is set per company, not per county. The county is genuinely the wrong unit of answer: your postcode decides.
Southern Water could not be confirmed, so check with them directly. Which of these applies at your address depends on which one bills you.
We could not confirm Southern Water’s current status from their own page, so we are not asserting a restriction. Check with your supplier before using a hosepipe.
