SAPC is coming. Are your smart meters ready?

SAPC (Standalone Auxiliary Proportional Controller) will soon be a requirement for smart metering technology in the UK, allowing users to control electricity loads. The question is, are your smart meters ready for a SAPC future?


Critical Software has developed the first available SAPC software that enables proportional control of up to five devices. A 20-minute assessment with one of our experts will give you the information you need to ensure your smart meters can integrate with a SAPC solution.


Our experience of DCC’s Great Britain Companion Specification means we can develop and test of SMETS2 smart metering devices including:

  • Auxiliary Proportional Controllers (APC)
  • Auxiliary Load Control Switches (ALCS)
  • Electricity Smart Metering Equipment (ESME)
  • Gas Smart Metering Equipment (GSME)
  • In-Home Display (IHD)
  • Prepayment Interface Device (PPMID)
  • Consumer Access Device (CAD)
  • Home Area Network (HAN) Connected Auxiliary Load Control Switches (HCALCS)
  • Hand-Held Terminal (HHT)

Take the first step towards a SAPC future.
