Kent is served by 4 different water companies, and a ban is set per company, not per county. The county is genuinely the wrong unit of answer: your postcode decides.
South East Water has a ban in force. Thames Water has a ban in force. Southern Water has a ban in force. SES Water has no restrictions. Which of these applies at your address depends on which one bills you.
You cannot use a hosepipe or sprinkler at home. A watering can or bucket is still fine, and the maximum fine is £1,000.
