Smart VS AMR Meters: What Is The Difference?

Advances in metering and energy technology has taken leaps and bounds over the last few years, meaning manual meter reads and estimated bills are becoming a thing of the past.

Many businesses already have AMR meters, but what is the difference between these and the new smart meters?

Firstly we’ll look at what each type of meter is:


AMR stands for Automated Meter Reading device. These meters work by creating a connection channel between a business customer and its energy supplier.

For AMR meters, the communication only goes in one direction, to the supplier. The energy supplier will receive meter reads once per month, so there is no need for manual meter reads. This ensures accurate billing and allows the customer to analyse their energy usage data.


  • They send accurate meter readings to the energy supplier so there are no more estimated bills
  • Improved security and tamper detection for equipment


Smart meters are the more technologically advanced version of AMR meters. Smart meters are required to be produced to an industry standard referred to as the Smart Metering Equipment Technical Standard (SMETs). The latest generation of smart meters are SMETS2, which feature many benefits over conventional and AMR meters.

They share the same functionality of AMR meters by automatically sending a meter reading and diagnostic data to your energy supplier, however they use a centralised data communication company (DCC) for their communications to the supplier. This allows them to both send and receive messages from their energy provider.

Smart meters also come with an optional Smart Energy Display which shows you exactly how much energy you’re using in real time. This allows businesses to gain more control over their energy consumption and bills.


  • They send accurate meter readings to the energy supplier so there are no more estimated bills
  • Improved security and tamper detection for equipment
  • Gives customers the option of having a smart energy display which shows real time energy usage in pounds and pence. This enables more detailed feedback of energy usage
  • Gives customers feedback on their energy usage to adjust their habits in order to lower their electricity bills
  • Helps the energy network to better understand the UKs energy demand to match supply
  • Can be operated as a pre-payment meter if you need help managing your payments and budgeting


Despite certain similarities, AMR and smart meters use different technologies and have their own benefits.

AMR meters only communicate from the customer to the energy supplier, whereas smart meters have two-way communication between the energy supplier and the business customer.

The amount of information they provide is also different. AMR meters only provide kWh information and possible peak kW demand for the month.

Smart meters send a lot more information, including; cumulative kWh usage, daily usage, peak kW demand, voltage information, outage information, time of use kWh and peak kW readings. They also send tamper notifications to the energy supplier.

Smart meters come with an optional Smart Energy Display, which shows you real time energy usage and how much you’re using in pounds and pence. This helps improve customers understanding of their energy usage, and means there will be less customer support queries.


The government has issued guidelines that require energy suppliers to offer smart meters to all domestic and small business customers by the end of 2020.

Although businesses who currently have AMR devices can keep them, in most cases businesses have not been able to have AMR meters installed in their since 21st May 2018. Any meter upgrade will automatically be to a smart meter for these customers.

Smart meters give businesses more control over their energy consumption and are ideal for businesses looking to reduce their energy bills. As well as showing real time energy usage data, businesses can now add a new layer of control as we can now offer pre-payment mode on our latest generation of smart meters.

Some customers may be interested in the benefits that pre-payment smart meters offer. These are ideal for certain SME business types providing an extra level of control to budgeting.
