How to read a smart meter

Smart meters automatically send readings to your suppliers, so needing to take a manual reading is much less common than with a traditional meter. Still, there are a few circumstances where you may need to take a smart meter reading. Here, we’ve gone over how to read a smart meter – for electricity and gas smart meters alike. Thankfully, the method is usually pretty similar from one smart meter to another.

How to Read a Smart Meter

When getting a smart meter, it’s fairly common to get the meters themselves mixed up with your in-home display. During a smart meter installation, you usually get an in-home display – this is a small portable device that displays energy usage information. It’s sometimes possible to take a reading from this in-home display, but most energy suppliers recommend using the actual meters.

Because smart meters automatically send readings to your supplier, you won’t normally have to take a reading at all. However, there are a few situations where you might need to read your smart meter, such as:

  • When you’ve just switched energy supplier. You’ll usually need to send the first meter reading yourself
  • You’ve switched supplier and they’re unable to connect to your meter. This is most common when you have an older smart meter
  • You may also want to check your smart meter to see how it’s changed recently

Submitting Meter Readings

The more regularly suppliers receive gas and electricity readings, the more accurate your bills will be. Without regularly readings, they’ll be forced to estimate your usage which may lead to higher bills.

If you have a smart meter, then readings should be automatically sent to your supplier on a regular basis (with every month being the minimum). Otherwise, all you need to do is call your supplier to give them the readings. If they have a function for doing this through their website or on an app, then these methods will probably end up being a little quicker.
