How to read your gas and electricity meters

What kind of energy meter do I have?

Electricity and gas meters come in all shapes and sizes! So before we get into the practicalities of meter reading, here’s how to work out which type of energy meter you have.

Traditional (non smart) meters

Any meter installed before 2011 will definitely be a traditional meter, as that’s when the smart meter roll out began. But traditional meters were still widely installed up to about 2017.  If your meter has dials, or a display with 4 to 6 black, white and red numbers, it’s very likely you have a traditional, non-smart meter.

Smart meters

Smart meters are the new generation of electricity and gas meters. They send readings to your supplier automatically using a secure wireless network. If you’ve got a smart meter, you’ll usually have a portable device called an in-home display (IHD) which helps you see how much energy you’re using. If you log into your online account, you’ll be able to see if your meter is a smart meter.

Multi-rate meter

If you’re on a plan like Economy 7 that gives you different prices for your electricity between day and night, you have a multi-rate meter. You’ll need to take 2 readings from it. Some multi-rate meters have 2 displays, showing your different rates. Others have a button you need to press to switch between the 2 readings.

Different makes and models of meter use different terms for the 2 rates. Here’s a table to help you know which reading’s which. 

You can get smart and traditional multi-rate meters.

Pay As You Go meters

You pay for your energy before you use it with a Pay As You Go (or Prepayment) meter. In short, they work like a pay-as-you-go phone – you buy credit for your meter, and top up whenever you need more. Read about them in our guide to Pay As You Go meters.

Pay As You Go meters can be traditional or smart. If you have a traditional Pay As You Go meter, you top it up using a card, token, or key. You take this to your local Pay Point or Post Office, to top up with cash.

Smart Pay As You Go meters can be topped up online or using our OVO Energy Top-up app, so you can easily top up on the go.

How to read your traditional electricity meter

Let’s start with how to find your electricity meter. Electricity meters are usually on an outside wall, inside a porch or entrance hall, or inside a cupboard in a living room. You could also find it in a basement, utility room, or garage. If you know where your consumer unit (fuse board) is – there’s a good chance your electricity meter is near it.

There are several types of traditional electricity meter, and you read them in different ways. It could have a standard (mechanical), dial or digital display, be a multi-rate meter or a Pay As You Go meter. 

How to read a standard (mechanical) or digital electricity meter

• Pretty simple! Just write down all the numbers you see, from left to right

• Ignore any numbers in red, or in a red box

• And ignore any numbers after a decimal point

So, the readings for the meters above would be 44955 and 30540.

How to read a multi-rate electricity meter

If you have a multi-rate plan, with lower-priced off-peak electricity (like economy 7), you’ll have more than one reading on your meter.

If you have a standard mechanical meter, there’ll be 2 rows showing your readings. But if your meter has a digital display, you’ll just need to press a button to scroll through the different rates. 

To read a multi-rate digital meter:

• Press the button to switch between rates.

• Make a note of the day rate and the night rate, ignoring any numbers after the decimal point.

• Next to the reading, there’s often a smaller 1 or 2 to show which rate is which (2 for the peak or day rate; and 1 for off-peak or night). If you’re not sure which is which, check your last meter readings on your bill.

• In the example above, there’s a sticker on the meter to show which rate is the low (or night) rate and which is the normal (or day) rate.

If you’re not sure when your peak and off-peak times start and stop, find out in your online account.

How to read a dial electric meter

Dial meters are slightly trickier. Each dial turns in the opposite direction to the one before. So first, check the direction of your dials. They might not be exactly like the example above. Every dial on every meter is numbered from 0 to 9. 

The pointer always moves upwards, from 0 through to 9, and then around again to 0. We always take the reading from the number the pointer is on, or has just passed, not the number it’s moving towards.

To read your dial electric meter:

1. Start with the highest-numbered dial first (in this example, the dial is 10,000 and the reading is 8).

2. Then work your way through the other dials from left to right, including any zeros.

3. If the pointer is directly on a number, write it down.

4. If the pointer falls between 2 numbers, write down the lower number. (Remember, the pointer hasn't reached the higher number yet.)

5. When a pointer falls between 9 and 0, write down 9. Reduce the reading you've already taken for the dial to its left by 1, since the pointer won't have reached that number, even though it’s very close. For example, in the picture above, if you wrote 8159_, when adding the next digit you’d need to correct it to 81589.

6. Ignore any red dials/numbers in red.

In this example, the correct reading is 81589.

How to read your traditional gas meter

First of all, where is your gas meter?

This isn’t a silly question! You’d be surprised how many of us don’t actually know. In most homes, the gas meter will either be in the kitchen, hallway or outside in a cupboard or meter box. If you live in a flat, the meters for your building might even be all together in a special meter room or in a box outside.

Make sure you find the right one for your home! It should be clearly labelled – but if you’re having trouble, check with your landlord or letting agent.

Gas use is calculated in 2 different ways. Older meters measure in imperial (with usage calculated in cubic feet) and newer meters work in metric (with usage calculated in cubic meters). 

How to read a digital metric gas meter

Digital metric gas meters have 5 main numbers, and will often have M³ on the front, or say “cubic metres”.

To read your gas meter:  

• Read the 5 numbers from left to right, in the order they appear, including any zeros

• Ignore any numbers in red, or in a red box

• Ignore any number after a decimal point (sometimes shown in red)

• In this example, the meter reads 00014

How to read a digital imperial gas meter

Digital imperial gas meters have 4 main numbers, and will often have ft³ on the front or say that it measures in “cubic feet”.

To read your gas meter correctly:  

• Read the 4 main numbers from left to right, in the order they appear, including any zeros

• Ignore any numbers in red, or in a red box

• Ignore any number after a decimal point (sometimes shown in red)

• In this example, the meter reads 5148

How to read a dial gas meter

Each dial turns in the opposite direction to the one before. So before you take a reading, check the direction of your dials. Every dial on every meter is numbered from 0 to 9. 

The pointer always moves from 0, counting upwards to 9, and then around again to 0. We always take the reading from the number the pointer is on, or has just passed, not the number it’s moving towards.

To read your dial gas meter:

1. You might see 4 or more dials – but you only need to read the 4 main ones. 

2. Start with the highest-numbered dial first (in this example, the dial is 1,000,000 and the reading is 7).

3. Then work your way through the other dials from left to right, including any zeros.

4. If the pointer is directly on a number, write it down.

5. If the pointer falls between 2 numbers, write down the lower number. (Remember, the pointer hasn't reached the higher number yet.)

6. When a pointer falls between 9 and 0, write down 9. Then you might need to take 1 away from the reading you've already done for the dial to its left (the pointer won't have reached that number, even though it’s very close). For an example, see the explanation on How to read a dial electric meter above.

7. Ignore any red dials/numbers in red.

In this example, the correct reading is 7205.

How to read your smart electricity meter

This depends on the type of smart meter you have. Here’s how you read the 4 types of meter that we usually install.

How to read an Aclara SGM meter

• Press the blue “A” button a few times, until you find a screen labelled “TOU Rate 1”
