Why isn’t my IHD showing the correct prices?

Smart tariffs like Octopus Cosy offer flexible electricity rates that change throughout the day based on peak and off-peak periods. Sometimes, your IHD may not show the current prices you’re being charged, making it tricky to track your energy use and costs.

Common reasons your IHD may not show the right smart tariff prices

  • Data update delays: IHDs depend on timely updates from your smart meter and supplier. Communication issues can cause your display to show old rates or defaults.
  • Tariff support limitations: Not all IHDs can fully support or properly display multiple-rate or time-of-use tariffs. Some models only show standard rates, even on more complex tariffs.
  • Supplier or network issues: Sometimes technical or system issues prevent suppliers from updating your meter with the latest prices.

What can you do if your IHD is not showing the correct price?

  • Check your supplier’s app or online account: This is the most accurate way to see your current rates and real-time usage.
  • Restart your IHD: Unplug, wait 30 seconds, and restart—this can sometimes refresh the data.
  • Contact your energy supplier: Report incorrect rates so your supplier can ensure your tariff is correctly set up and, if possible, remotely update your smart meter.
  • Understand the limitations: Even if your IHD can’t display every rate, your supplier’s system will still bill you accurately according to your tariff.

Summary:
 It’s frustrating when your IHD doesn’t reflect your smart tariff (like Octopus Cosy). This is common due to technical limitations, delays, or your IHD model. It won’t affect your actual charges. Always check your supplier’s own website or app for the correct rates and contact them if you continue to see problems.
