NHH (Non Half Hourly) 05-08 metering – Licence Conditions with guidance notes for the provision of advanced metering for larger business sites



In April 2009 the government introduced a requirement for Suppliers to provide advanced metering for larger non-half-hourly read electricity and non-daily read gas sites in the non-domestic sector. For electricity this affects about 170,000 sites in Profile Classes 5 to 8. The requirement applies to new and replacement meters, with advanced metering to be installed for all such sites by 06 April 2014.

ENMAT provides replacement metering solutions for customers still using profile classes 5 to 8.  Contact ENMAT today to discuss your needs.

  • Came into force April 2009


  • Obligation on all electricity and gas suppliers to install AMR by 5/4/2014


  • Applies to non-domestic supplies


  • Electricity profile classes 05 to 08


  • Gas sites with a measured annual consumption ≥ 732,000 kWh


  • Applies to all new supplies, any replacement meter and to all relevant supplies after 5th April 2014


  • In effect, from 2014 onwards suppliers can only use Advanced Metering on these larger non-domestic supplies

What is a Non-half-hourly metered supply?

For non-half-hourly metered supplies, the NHHDC determines the consumption by calculating the advance (the difference between the last two meter reads, this is annualised to produce an annual advance (AA), this being the data the supplier will pay on).

The NHHDC is also responsible determining the estimated annual consumption (EAC), which is a forecast for a year ahead. The EAC is initially provided by the supplier, and thereafter forecast based on actual meter readings.

Data from the DC (EAC/ AA’s) is provided to the non half hourly data aggregator, which aggregates the individual values provided into a single figure split in a number of ways e.g. geographically, geographically & supplier or supplier. This aggregated data is then provided to the Central Systems, maintained by Elexon, to determine the value of energy which has been used by suppliers so that they are able to settle with the distribution network which generated the energy. The process is known as balancing and settlement and falls under the balancing and settlement code (BSC).
