If you’ve ever stood staring at your smart meter, wondering which numbers to write down or why it’s flashing at you, you’re not alone.
Smart meters are designed to make energy management easier, but for many UK households, they can still feel confusing. Whether you’re submitting a reading to your supplier, moving house, or simply checking your energy use, knowing how to take a meter reading from a smart meter can save you time, stress, and even money.
- How to read different types of smart meters (electricity and gas)
- What all those numbers actually mean
- When you need to take a manual reading (even if your meter is “smart”)
- How to fix common issues with readings
- And how accurate meter readings can help you lower bills
Why Smart Meters Matter
Smart meters are the next generation of energy meters being rolled out across the UK as part of a government-backed plan to modernise the grid.
Unlike traditional meters, smart meters automatically send readings to your energy supplier, so you no longer need to submit them manually every month.
According to Ofgem, smart meters help:
- Improve billing accuracy (no more estimated bills)
- Track real-time energy use
- Support a greener, more flexible energy system
However, there are times when you might still need to know how to take a meter reading from a smart meter, such as if your meter temporarily goes offline, you switch suppliers, or you just want to double-check your usage.
Understanding How Smart Meters Work
Smart meters measure the amount of gas or electricity your home uses , just like traditional meters , but they also include wireless communication technology that sends data to your supplier via a secure network.
Every smart meter setup typically includes two main components:
- The Smart Meter , Installed on your gas and electricity supply, usually near your existing meter location.
- The In-Home Display (IHD) , A small screen that shows your usage in pounds and pence, as well as kWh (kilowatt hours) for electricity or m³ for gas.
Together, these devices give you an instant view of how much energy you’re using, when, and how much it’s costing you.
If your smart meter has temporarily lost connection (for example, after a power cut), you may still need to read it manually , which is exactly what we’ll cover next.
When You Need to Take a Smart Meter Reading
Even though smart meters are designed to send readings automatically, there are times when you’ll still need to know how to take a meter reading from a smart meter.
Here are the most common scenarios:
- You’re switching suppliers: Some suppliers ask for a final reading when you switch to ensure accurate billing.
- Your meter has lost connection: Smart meters rely on mobile networks; if the signal drops, they can’t send data automatically.
- You want to verify your bills: Checking your readings manually helps confirm your bills match your actual usage.
- You’ve moved house: You’ll need to give your new supplier accurate readings on move-in and move-out days.
- You want to track usage trends manually: Some households prefer keeping their own records, especially if they’re trying to save energy.
How to Take a Meter Reading from a Smart Meter
Different smart meters display readings in slightly different ways, depending on the manufacturer and model. Below we’ll explain how to read the most common types used across the UK: SMETS1 and SMETS2 meters.
How to Read a Smart Electricity Meter
For a SMETS1 Electricity Meter (Older Type)
- Press the “A” button to wake up the screen.
- Keep pressing until you see the word “TOTAL ACT IMPORT” or “IMP KWH.”
- The number displayed (e.g. 005324.2) is your electricity reading.
- Ignore the numbers after the decimal point.
For a SMETS2 Electricity Meter (Newer Type)
- Press either the “A” or “OK” button to wake the screen.
- Look for a number next to “kWh” , that’s your total energy usage.
- If your meter displays multiple screens, select “Meter reading” or “Total energy used.”
- Note the figure before the decimal point.
How to Read a Smart Gas Meter
For a SMETS1 Gas Meter
- Press the “A” button to activate the screen.
- You’ll see a number next to “VOLUME” or “M3.”
- Write down the first five digits (ignore decimals or zeros at the end).
For a SMETS2 Gas Meter
- Wake the display by pressing “OK” or “A”.
- The screen should show “Meter index” , this is your gas reading.
- Record the digits before the decimal point (e.g. 00324).
Tip: Gas readings are shown in cubic metres (m³), while electricity is measured in kilowatt hours (kWh).
Using Your In-Home Display (IHD)
Your In-Home Display is the easiest way to monitor and understand what affects your energy consumption , and it can also help you confirm your readings.
What You’ll See on the Screen:
- Electricity usage (kWh)
- Gas usage (m³)
- Real-time costs in £/hour
- Daily and monthly usage summaries
If you want to check your usage without walking to the meter cupboard, the IHD is your go-to tool.
For example: If your IHD shows a spike at 6 PM, that’s likely due to cooking, heating, or charging multiple devices at once.
Common Smart Meter Problems (and Fixes)
1. My IHD isn’t showing any data
- Check that it’s plugged in and within 5–10 metres of your smart meter.
- Restart it by unplugging and plugging back in.
- If still blank, contact your supplier for a signal refresh.
2. My smart meter isn’t sending readings
- Take a manual meter reading from your smart meter.
- Check your last bill , if it says “estimated,” your meter may have lost signal.
- Ask your supplier if your meter is SMETS1 (older model) , these sometimes go “dumb” after switching suppliers but can be reconnected.
3. My bills are too high
If you suspect billing errors, take manual readings weekly and compare them with your supplier’s records.

Understanding Your Smart Meter Readings
Knowing how to take a meter reading from a smart meter is only part of the puzzle , understanding what those numbers mean can help you take control of your energy usage.
| Reading Type | Unit | What It Means |
| Electricity | kWh | Total energy used , 1 kWh = 1,000 watts for one hour |
| Gas | m³ | Volume of gas used (converted to kWh for billing) |
| Cost | £ | Based on your tariff’s rate per kWh |
For example: If your meter shows 005324 kWh, and your rate is £0.30 per kWh, your usage is roughly £1,597.20 for that period (before standing charges).
Checking readings monthly helps you identify usage spikes , such as heating surges in winter or increased summer cooling.
Why Accurate Smart Meter Readings Matter
Even with automatic updates, taking a manual meter reading from a smart meter every month is a smart habit.
- Avoid estimated bills that may overcharge you.
- Identify wasted energy , for instance, appliances left on overnight.
- Track energy-saving improvements (like insulation or efficient lighting).
- Support the UK’s Net Zero goals by enabling smarter grid management.
According to GOV.UK – Smart Meter Benefits, over 30 million UK homes now use smart meters , and the data helps both households and suppliers build a more energy-efficient system.
How Often Should You Take Readings?
- You’ve recently changed supplier or tariff.
- You’re budgeting for energy bills.
- You want to double-check your direct debit accuracy.
Manual readings act as a safety net , ensuring that your supplier’s automatic readings align with your real usage.
Consumer Tip: Don’t Fear the Buttons
- “A” or “OK” usually scrolls through options.
- “B” often moves backward or exits a menu.
You can’t accidentally “reset” your meter by pressing buttons , it’s safe to navigate and explore.
If you ever get stuck, visit your supplier’s help page for specific meter model instructions, or check Citizens Advice – Reading Your Meter.
How to Read Prepayment Smart Meters
If you’re on a pay-as-you-go (PAYG) smart meter, readings still matter. They show how much credit you’ve used and help you manage top-ups more efficiently.
- Press the “A” button until you see “Credit” or “Balance.”
- Press again to show “Total usage.”
- The number next to kWh or m³ is your reading.
You can also check your IHD to see remaining credit, emergency balance, and daily usage trends.
If you’re regularly running low, consider switching to a direct debit plan to avoid higher PAYG rates.

Winter Tip: Monitor Seasonal Energy Usage
During colder months, heating and lighting can double or even triple your electricity and gas consumption.
To stay on top of winter bills:
- Take readings every two weeks.
- Track your usage on the IHD.
- Consider switching to a time-of-use tariff that rewards off-peak usage.
These simple habits help you understand how your home uses energy and make smarter choices.
How Smart Meters Support Sustainability
Every meter reading from a smart meter contributes to a smarter, greener grid.
By providing real-time usage data, smart meters allow suppliers to balance supply and demand more efficiently, reducing energy waste and supporting renewable sources like wind and solar.
That means your readings don’t just help you, they help the planet.
Final Thoughts
Learning how to take a meter reading from a smart meter doesn’t have to be complicated. Once you understand which buttons to press and what the numbers mean, you’ll gain a clearer picture of your energy habits , and how to improve them.
Remember:
- Check your readings monthly (especially after switching suppliers).
- Use your in-home display to monitor usage and costs in real-time.
- If your bills seem off, take manual readings and contact your supplier.
Accurate readings empower you to stay in control, save money, and help build a smarter, greener energy future.
