Understanding your Landis+Gyr e470 smart meter

The Landis+Gyr E470 is a widely installed SMETS2-compliant smart electricity meter in the UK, designed to measure and automate electricity consumption readings. These meters reduce the need for manual submissions and support smart-meter-dependent tariffs.

What is the e470?

The E470 is a digital meter that replaces older, analogue models, providing more accurate and frequent data about your energy use. It connects homes to the smart grid, allowing your energy supplier to receive readings automatically. Knowing how to interact with it directly can be useful for monitoring consumption or when smart functionality is temporarily unavailable.

Identifying your meter's SMETS version

Smart meters in the UK are categorised as either SMETS1 or SMETS2, with SMETS2 offering enhanced functionality and interoperability. The E470 model can be either SMETS1 or SMETS2, which can be confusing as they often look similar.

The easiest way to identify your meter's SMETS version is to check its installation date; meters fitted before March 2019 are almost certainly SMETS1, while those installed after September 2019 are most likely SMETS2. For meters installed between these dates, or if you're unsure, contact your energy supplier; they will have the information on file.

A key visual difference for SMETS1 Landis+Gyr E470 meters is often a separate Communications Hub (Comms Hub) located next to the meter, such as a Trilliant SEAP-2001-V. SMETS2 E470 meters typically integrate the communications hub, meaning there's no separate box. SMETS2 meters also typically have one green and one grey button, and never have a black border around the display.

SMETS2 meters are the current standard and are designed to retain smart functionality even if you switch energy suppliers. Many SMETS1 meters have been or are being migrated to the national Data Communications Company (DCC) network, allowing them to behave more like SMETS2 meters and survive supplier switches.

Navigating your e470: buttons and display

The Landis+Gyr E470 meter features a liquid crystal display (LCD) and two main buttons, typically labelled 'A' and 'B'.

Key buttons and their functions

Hold button 'B' to open the Tariff Display List, which will show the first rate. Press button 'A' to move to the next rate displayed on the meter.

Common display codes and what they mean

The E470 cycles through various screens, each displaying different information. The most important reading for billing purposes is usually labelled "TOTAL Act Import" or "kWh". This shows your total electricity consumption in kilowatt-hours (kWh).

If you are on a dual-rate tariff (like Economy 7), your meter will display separate readings for different times of day, often labelled "Rate 1" and "Rate 2" (or "R01" and "R02"). "Rate 1" typically represents daytime usage, and "Rate 2" nighttime usage.

The meter may also show messages related to its operational status, such as "Credit Accepted" after a top-up on a prepayment meter, or error messages like "Invalid code" if a top-up code is entered incorrectly.

How to read your Landis+Gyr e470 meter

Manually reading your Landis+Gyr E470 meter is straightforward once you know which buttons to press and what to look for.

Taking an electricity reading

1. Locate your meter: It's often found near your fuse box, under the stairs, or in a cupboard.
2. Wake the screen: Hold button 'B' to open the Tariff Display List. This will also activate the display.
3. Find your reading: The first screen you see after holding 'B' will be your first rate (e.g., "TOTAL Act Import" or "kWh"). Record all the digits shown before any decimal point. Ignore any leading zeros.
4. Dual-rate tariffs: If you're on a dual-rate tariff, press button 'A' to move to the next rate (e.g., "Rate 2"). Record this reading separately.

The Landis+Gyr E470 is an electricity meter; if you have gas, you will have a separate gas smart meter installed elsewhere. Gas meters display usage in cubic metres or cubic feet, not kWh, and must be read separately. For more details on how to read different smart meters, see our guide on how to read your smart meter.

Understanding your readings

Meter readings are used to calculate your consumption for billing purposes. The average UK home uses around 2,700 kWh of electricity per year. Your readings, combined with your tariff's unit rate and standing charge, determine your energy bill. Regularly checking your meter readings can help you track your energy usage and identify any unexpected spikes. Understanding your energy bill can also help you manage your consumption more effectively.

Troubleshooting common Landis+Gyr e470 issues

While Landis+Gyr E470 meters are generally reliable, you might encounter occasional issues.

Meter not displaying

If your E470 screen is blank and doesn't respond to button presses, try pressing and holding a button on the meter for about 10 seconds to wake the display. If the display remains unresponsive, contact your energy supplier. They can remotely diagnose the issue and may need to send a technician for a potential replacement.

Smart functionality issues

If your smart meter isn't sending automatic readings to your supplier, or your in-home display (IHD) isn't working, this could indicate a communication problem. However, an IHD not working does not necessarily mean the smart meter itself is offline. SMETS1 meters, particularly older ones, sometimes lose smart functionality after a supplier switch if they haven't been migrated to the DCC network. SMETS2 meters are designed to avoid this.

Suppliers aim to resolve connectivity issues for commissioned meters within an operational resolution window of 42 days from when the issue started. If the meter is still not connected after this period, a meter exchange or specialist investigation may be arranged.

Safety warning

Never attempt to open or tamper with your smart meter. This can be dangerous, illegal, and could damage the meter or void warranties. Smart meters are the property of your energy provider and are designed to be tamper-proof and remotely managed. Always contact your energy supplier for any serious problems or concerns; they are the authorised personnel to handle meter resets and repairs.

Maximising your energy control with the e470

Understanding your Landis+Gyr E470 meter is the first step towards taking control of your energy consumption.

Beyond basic readings

Your E470 smart meter provides more than just billing data; it offers insights into your energy behaviour. By regularly checking your meter or using an in-home display (IHD), you can see how much electricity you're using and when. This information is invaluable for identifying energy-intensive appliances or habits and making informed decisions to reduce your consumption. The E470 supports flexible tariffs, allowing you to potentially benefit from cheaper electricity during off-peak hours if you adjust your usage patterns.

Connecting your meter to better energy management

The data from your Landis+Gyr E470 meter can be a powerful tool for energy management. By understanding your usage patterns, you can make conscious choices to reduce your energy footprint and potentially lower your bills.
