Abort Reason
Next Action
  • For SMETS installations several electricity meter variants are required to cover all types of customer supplies, for example, 1 phase supplies, 3 phase supplies and 5 terminal meters for switched heating load.

  • If your job has been Aborted for this reason you could choose to wait until the correct meter variant becomes available, or alternatively instruct IMServ to install AMR metering.

  • Alternatively, before attending site Suppliers should attempt to filter-out premises where a suitable meter type is not available, while this is generally effective we accept that it’s not 100% reliable. In the UK we have a small number of NHH site with Current Transformer (CT) meters, no SMETS meter manufacturers have committed to building a CT SMETS meter, these sites are suited to AMR/HH metering.

  • This abort reason will only be used if the DCC Service Centre notify IMServ that they are unable to communicate with the remote devices. If this occurs IMServ will attempt to rebook an appointment for a date when DCC service has resumed without the Supplier needing to re-request.

  • Most Suppliers have instructed IMServ to follow the 'Install and Leave' process so our Technicians will fit meters regardless of WAN signal availability, as a result this Abort reason is rarely used.

  • If you do decide you want IMServ to Abort all jobs where we are unable to establish WAN, as Supplier you will need to monitor the on site situation and re-instruct IMServ if/when appropriate to do so when WAN coverage is available.

  • On occasion we may install a meter and successfully establish the WAN, but we are still unable to establish the HAN. As a general rule these problems don’t occur during electricity only installations, it’s more likely to occur for Gas installations where the Gas meter is located some distance from the communication hub.

  • To address the issue the industry is waiting for Dual Band Communication Hubs (DBCH) to become available, the expectation is that the lower frequency 868MHz communication hubs will be more effective in penetrating thick walls. 

  • The Supplier needs to monitor the situation and inform IMServ to re-attend when the issue is likely to have been resolved.
