Half-hourly meters provide more accurate information by providing electronic meter reads every 30 minutes. Half hourly meters are typically used by large/high energy users with a demand higher than 100kVA. You can ascertain whether you are a half hourly customer by checking the top line of your MPAN and to see if it starts 00. You will find this on a copy of your bill under supply details. You can also tell as there will be a communications link so the meter can be read remotely daily. We have allocated account managers that specialise with dealing with Half Hourly meters for our clients.
