Glossary Term: Non Half Hourly
Acronym: NHH
Non-half hourly meters generally require customers to submit manual readings to their supplier, or, if they are smart meters, automatically submit readings once a day, monthly or longer, depending on the settings. This is compared to Half hourly meters that produce meter readings every 30 minutes.
