EDMI meter reading: your step-by-step guide

Accurately reading your EDMI energy meter is essential for correct billing and understanding your energy use. This guide provides clear, step-by-step instructions for reading common EDMI electricity and gas meters, helping you avoid estimated bills and stay in control of your energy consumption.

Understanding your EDMI meter

What is an EDMI meter?

EDMI meters are a common type of smart meter installed in UK homes for both electricity and gas supplies. These devices record your energy consumption, often displaying readings for different rates to accommodate various tariffs. While smart meters are designed to send readings automatically to your energy supplier, understanding how to read your EDMI meter manually remains a valuable skill for verification or in case your meter goes offline.

Why accurate readings matter

Accurate meter readings are crucial for ensuring you're billed correctly for the energy you use. Without them, your supplier might have to estimate your consumption, which can lead to overpaying or underpaying. Regular manual checks, even with a smart meter, help you keep track of your usage, verify your bills, and prevent any billing confusion. This is particularly important with the ongoing phase-out of older systems like the Radio Teleswitch Service (RTS), which requires replacement with modern smart meters, including EDMI models.

How to read your EDMI electricity meter

General steps for EDMI meters

Reading most EDMI electricity meters follows a similar pattern. You'll typically need to wake up the display, navigate through a menu, and then record the numbers for each rate.

1. Locate your meter: Find your EDMI electricity meter, usually in a utility cupboard, under the stairs, or near your fuse box.
2. Wake the display: Press any button, often "OK" or "A", to activate the screen. If the display is blank, try holding the button down for a few seconds.
3. Navigate to readings: Hold the "OK" button until "Billing" appears on the screen. Hold "OK" again to enter the Billing menu.
4. Access advanced options: Use the arrow buttons (often ">") to scroll to "Advanced" and hold "OK" to select it. "TOUmtrx" should then appear.
5. View rates: Hold "OK" to enter the TOU matrix sub-menu. You'll see "RATE1" displayed. Use the arrow buttons to view "Rate 1" and "Rate 2" if you have a multi-rate tariff.
6. Record your reading: Write down the full number displayed for each rate, ignoring any digits after the decimal point.

Reading an EDMI ES 10B meter

For the EDMI ES 10B, the navigation is similar to the general steps, focusing on the "OK" button for selection and arrow keys for navigation. You'll typically find your readings under the "Billing" or "Advanced" sections after waking the display. Pay close attention to the rate indicators (e.g., Rate 1, Rate 2) to ensure you're recording the correct consumption for your tariff.

Reading an EDMI Mk10 meter

The EDMI Mk10 meter also uses a button-based navigation system. After waking the display, you'll generally follow the path through "Billing" and "Advanced" to reach the "TOUmtrx" (Time of Use matrix) where your Rate 1 and Rate 2 readings are stored. Ensure you hold the "OK" button to select menu options and use the arrow keys to cycle through the different rates.

How to read your EDMI gas meter

Identifying your gas meter display

EDMI gas meters often have a similar display and navigation to their electricity counterparts, though they typically only show a single reading as gas tariffs are usually single-rate. Your gas meter will usually be located outside your property in a meter box, or sometimes indoors near the gas supply entry point.

Getting your gas meter reading

1. Locate and wake: Find your EDMI gas meter and press a button (often "OK" or "A") to wake its display.
2. Navigate: Similar to electricity meters, you may need to press "OK" to enter a menu, often labelled "Billing".
3. Find the reading: Look for a screen displaying a single consumption figure, usually labelled "Total" or "Volume". Record the full number, ignoring any digits after the decimal point. Gas readings are typically in cubic metres (m³) or cubic feet (ft³), which your supplier converts to kilowatt-hours (kWh) for billing.

Interpreting your EDMI meter readings

Understanding rate 1 and rate 2

Many EDMI meters display readings for different rates, commonly "Rate 1" and "Rate 2". These rates are used for multi-rate tariffs, such as Economy 7, where electricity costs vary depending on the time of day. Rate 1 typically records your peak-rate consumption (more expensive), while Rate 2 records your off-peak consumption (cheaper). If you're on a single-rate tariff, you might only see a reading for Rate 1, or both rates might show the same total.

What your readings mean for your bill

Your meter readings directly influence your energy bill. By providing accurate readings, you ensure your bill reflects your actual energy usage, rather than an estimate. Smart meters, including EDMI models, are designed to send automated readings to your supplier. However, manually checking your meter allows you to:

• Verify accuracy: Compare your meter's display with the readings on your bill to ensure consistency.
• Track usage: Understand how much energy you're consuming over time, which can help you identify patterns and potential areas for savings.
• Avoid estimates: If your smart meter is offline or not communicating, a manual reading prevents your supplier from having to estimate your usage.

Troubleshooting common EDMI meter issues

Blank or unresponsive display

If your EDMI meter display is blank or unresponsive, try these steps:

1. Press and hold: Often, simply pressing and holding any button (e.g., "OK" or "A") for a few seconds can wake up the display.
2. Check power: Ensure the meter has power. For electricity meters, check your main fuse box. For gas meters, a blank display might indicate a low battery, as gas meters are battery-powered.
3. Wait: Sometimes, meters can go into a power-saving mode or temporarily lose display. Wait a few minutes and try again.
4. Contact your supplier: If the display remains blank or unresponsive, contact your energy supplier. They can diagnose the issue, which might include a faulty meter or a low battery in a gas meter.

Incorrect readings or display errors

If you suspect your meter is displaying incorrect readings or showing error codes:

1. Re-read carefully: Double-check your reading, ensuring you're looking at the correct rate numbers and ignoring decimal places.
2. Consult manual: If you have your meter's manual, check for explanations of any error codes displayed.
3. Compare with bill: Cross-reference your current reading with previous bills to spot any significant, unexpected discrepancies.
4. Contact your supplier: If you continue to believe the readings are incorrect or an error code persists, reach out to your energy supplier for assistance.

When to contact your supplier

You should contact your energy supplier if:

• Your EDMI meter display is consistently blank or unresponsive.
• You see persistent error messages you can't resolve.
• You believe your meter is faulty or providing inaccurate readings.
• You need help understanding your tariff rates as displayed on the meter.
• You have an older RTS meter that needs replacing. The RTS is being switched off, and your current supplier is responsible for replacing it with a smart meter free of charge.

Submitting your meter reading

If you have an EDMI smart meter that is online and communicating, it should send readings automatically to your supplier. However, there are times you might need to submit a manual reading:

• Verification: To confirm the accuracy of your automated readings.
• Offline meter: If your smart meter is temporarily offline or not communicating.
• Switching supplier: Your new supplier may request a manual reading to ensure a smooth transition.
• Estimated bills: If you've received an estimated bill, submitting an accurate reading can help correct it.

Most energy suppliers, including Fuse Energy, offer easy ways to submit readings through their website or app. Fuse Energy provides clear guidance on reading your meters and offers 24/7 human customer support to assist with any difficulties you encounter.
