Reading Electric Meters – How to Take Readings From Different Types of Electrical Meters Including Standard, Digital, Punch and Economic system 7 and x Meters
If you have never taken an electrical meter reading before information technology tin can be quite disruptive. Using the guide below, yous will learn all near the unlike types of electric meters that include standard electric meters, the digital meters, dial meters and the two different Economic system 7 and x meters. Yous volition also learn how to calculate how much a given appliance could cost to run.
Electric meters or energy meters as they are also known are installed in pretty much every abode or commercial premises in the country that has a connection to the electrical grid.
The meter is used to calculate how much electricity has been used or consumed by the occupants of the premises to power electrical appliances such every bit Boob tube'south, fridges, freezers and other household goods so that their given free energy supplier gas accuse for what's been used.
The meter itself measures electrical usage in "units". With most meters, one unit of measurement of electricity consumed is equal to one kilowatt hour (or kWh for short) or if 1000 watts of power is drawn consistently over the period of one hr, this equals 1 kWh or 1 unit.
How to Read an Electric Meter
At present that nosotros have looked at the various unlike types of electrical meters and how they display electric usage, it'south now time to accept a look at how you lot actually have a meter reading from each unlike type of meter.
How to Read a Standard Electric Meter
Reading a standard electric meter to give your free energy supplier a meter reading is a fairly straightforward job. All you lot have to practise is provide your supplier with the numbers in black or on a black surroundings, reading them from left to right.
You may also notice that there are numbers in red or on a cherry-red background. These are effectively decimals and can be safely ignored equally your supplier is merely interested in the whole numbers.

How to Read a Punch Electrical Meter
These are arguably the trickiest types of electrical meters to read due to the number of dials and more chiefly the management in which each punch is read. This is ordinarily the office that catches people out.
Equally we accept mentioned above, each dial alternates in terms of which direction it's read in. Most meters start with the first dial on the left being read in a clockwise management and the next one to it's correct beingness read in an anti-clockwise direction and so on.
Substantially, the first, third and fifth dials are read clockwise, while the 2nd and fourth dials are read anti-clockwise.
A proficient indicator in terms of which mode the punch should exist read is which way the numbers around the face run. If they run clockwise, then read the meter clockwise, but if they run anti-clockwise, read the meter in an anti-clockwise direction.
Each dial will run all the way effectually from 0 to 9, at which point information technology then starts again.
There are likewise a few rules to exist aware of when reading the dials:
- Ever commencement with the punch furthest to the left and then read across to the right
- If the dial mitt falls between two numbers go with the lowest number due east.yard. if it falls half way between 8 and 9, go with eight
- If the dial hand falls betwixt 0 and 9 on any punch so always get with the 9
- If you lot have a reading of 9 on whatever of the dials and so you will demand to reduce the reading of the dial to information technology's left by 1 e.g. if the fourth dial reads nine and the third dial to its left reads three, this numbers needs reducing to 2
- You don't need to record the concluding dial. These are ordinarily coloured red or labeled 1/10

How to Read an Electronic or Digital Electric Meter
Once more, as with the standard electric meter, the digital meter is pretty straightforward to read. On the digital LCD display, record all of the numbers to the left of the decimal point including any nix values.
Whatsoever numbers to the right of the decimal signal can exist safely ignored.

How to Read Economy 7 and Economy 10 Electrical Meters
Equally we have discussed above, Economy seven and Ecomony ten meters characteristic two displays if their the older type mechanical meters or if you lot have a digital meter, in that location volition be meter view select button or the meter itself volition simply alternate between reading views.
Equally we have stated above, if at that place is any mention of "multirate" on the meter housing then you tin be certain that the digital meter you lot are dealing with is indeed an economic system seven or x meter. Even so, if it mentions single rate then it'southward only a standard digital meter on a standard tariff.
If yous've established your digital meter is indeed a multi-rate meter then you will need to supply ii meter readings to your supplier – your on-peak and off-summit readings.
Most digital multi-charge per unit meters will simply alternate their display to testify either the on-pinnacle or off-peak reading. If you watch it for long plenty you should come across information technology change.
The given reading you lot are viewing will exist signified by the small number to the left of the actual reading – either 1 or two
But note downwardly each reading onto a piece of paper and and so transfer them to your suppliers chosen method of capturing the readings. In most cases, this will exist an online portal of some kind.
In the instance that you take an older mechanical meter, both readings should be displayed and easy to run into. Only note each one down and transfer them to your supplier for billing.

How to Read a Prepayment Electric Meter
Every bit the name would suggest, if you have a prepay meter and then you take to pay for your electricity upfront before you use it and due to this, chances are that your supplier will not require a meter reading, simply on the odd occasion they may exercise.
If they do, but locate your meter and view the digital LCD display. In the majority of cases, the brandish volition be set up by default to evidence the remaining credit on the meter, merely in that location should also be a push button somewhere on the front that will allow you to change the default view and show total usage.
Simply printing the push to gyre betwixt each view.
If however, you cannot run across whatsoever buttons and then you lot will demand to consult your supplier
How to Read a Smart Meter
This is a flake of a trick as the reply to "how do y'all read a smart meter" is you don't, that'south essentially i of their main plus points.
Well, I guess that's not strictly true every bit if you do have a smart meter, then yous should be checking the free energy usage in your home as often as possible so that you lot tin can meet what appliances are using the near and when need within the dwelling is at its highest.
From the perspective of reading the meter to get a reading to requite to your supplier so that they can beak you for your usage, and then this is certainly non required as smart meters feed usage data directly to your supplier, without the need for you to supply information technology yourself.
However, if you lot do desire to view your total usage in kWh, and then this is certainly possible, just accessing the information will depend on the type of meter yous have:
- Smart Meter with Keypad: Press ix on your meters keypad and you should then see some letters appear, normally along the lines of IMP KWH. This will be followed by a series of eight digits that shows your full usage figure
- Smart Meter with 2 Buttons: Press the button labeled Display Select or sometimes just Display. The meter should then display your usage reading. It's the series of numbers followed by kWh
- Smart Meter with A/B Buttons: To view your usage figure, simply printing the A button until y'all run across something similar to "Full ACT IMPORT" and the serial of digits below followed past kWh are your usage numbers
- Smart Meter with 3 Buttons: Simply press the eye push until you see a series of numbers preceded by kWh and this will be your total usage effigy
- Smart Meter with Orange Push button: Press the orange button and you should then B

Reading Economic system vii Smart Meters
Smart meters are besides bachelor for Economy 7 and some economy 10 tariffs.
If you have a smart meter with a fundamental pad and economic system seven, printing the number half-dozen button until you can see "IMP R01". The digits preceding this should be full usage for off-height hours.
To view your on-peak usage, merely press the number 6 button again until you meet "IMP R02" and the following numbers will land your on-peak usage
If you accept a three button meter, press the centre push until y'all meet R1 and R2. R1 should indicate your off-superlative tariff usage and R2 should land your normal rate of on-peak usage.
Notation: In gild to access your full usage effigy in kWh, y'all will demand to use the smart meter itself and not the in-dwelling brandish unit.
One terminal point to exist aware of in terms of your electric meter is that every meter installed in the UK has it'south own MPAN number (supply number or Southward-Number as they are also known). This number is totally unique and is used to identify your individual meter.
When viewing your bills or completing a paper or online class to submit your meter readings, information technology's a expert idea to also check the MPAN number quoted on the paperwork or you lot online portal confronting your ain meter just to make sure they are the aforementioned.
What Unlike Types of Meters are There?
The blazon of meters used to measure out electricity consumption in a given belongings or building vary greatly around the world, simply here in the United kingdom of great britain and northern ireland there are substantially six dissimilar type of electricity meter.
The blazon of meter that is used will very much depend on the requirements of the user:
- Standard Electricity Meter: The standard electricity meter is the most popular type of meter and features in the majority of United kingdom of great britain and northern ireland homes. It'south a fairly basic type of meter and measures electricity used in kWh (kilowatt hours). The total usage is displayed via a mechanical dial display which makes information technology very easy to take a reading
Standard electric meter with mechanical dial
- Dial Electricity Meters: This type of meter operates in a similar fashion to the standard meter, but instead of a line of numbers you take a serial of dials that wait similar mini clocks. To misfile things a little more than, each punch normally turns in a dissimilar management, either clockwise or anti-clockwise

- Digital Electricity Meters: Again, pretty similar to the standard electricity meter, but instead of take a mechanical dial display, yous have an LCD display. I betoken to annotation is that if at that place is any mention of multi-rate anywhere on the meter so the chances are this volition be an economic system vii or 10 meter, merely if single rate is mentioned so chances are this is simply a standard digital meter
Modern standard digital electric meter
- Economic system 7 and Economy 10 Electric Meters: In most cases economy seven and 10 meters are like to the standard electric meters, in that they display usage in kWh via a mechanical dial, but instead of having ane punch display you will have two. Economy seven and economy 10 tariffs charge dissimilar rates per kWh for on-peak and off-peak electricity usage, and then one dial is for on-meridian usage and the other dial is for off-peak usage
Economic system vii electric meter with dual mechanical dials
- Prepayment Electricity Meters: Equally the name suggests, this type of meter requires the user to pay for their electricity in advance as opposed to paying for what has been used. In times past, prepay meters operated on coins (some of you may remember this) but today a card or key is used to purchase credit. In terms of display, prepay meters are generally digital and feature a push that tin change the display from remaining credit to full usage

- Smart Electrical Meters: The smart meter is very much at the cutting border of electrical metering. They can accurately measure existent-time electrical usage and besides many other things. Smart meters likewise communicate directly with your supplier so you lot don't take to worry nigh supplying meter readings and they also do away with estimate billing so yous are actually charged for what you utilize equally opposed to what your supplier things you lot might employ
Smart electrical meter
The blazon of meter that works best for you volition very much depend on how and when y'all utilise the electricity in your dwelling house.
If you live in a fairly decorated house, where many people are in and out for nigh of the twenty-four hour period then you're going to want a constant supply of electricity at a adept rate.
In light of this then a standard meter, dial meter, digital meter or smart meter coupled with a competitive stock-still rate electrical tariff will probably exist the way to get. With the emergence of and so many comparision sites over the last few years, information technology's now very easy to compare free energy suppliers and the tariffs they take on offer and go the all-time deal for you.
If however, the majority of your electrical usage will be during off-peak night time hours, then an economy 7 or economy x tariff and accompanying meter may exist the all-time solution for you.
Why do y'all Need to Supply Electric Meter Readings?
If you have a smart meter, then supplying meter readings to your free energy supplier is not needed as the meter itself does this for y'all.
However, if you don't accept a smart meter, then you will demand to provide your supplier with your electric meter readings yourself.
Ideally, yous should provide readings at least every 3 months or even better, every month if you tin. This will enable your electric supplier to neb yous much more than accurately as they will have a much amend thought of your usage.
In the issue that you don't supply your readings regularly then your supplier will provide you with an guess nib. This means that they will neb you lot on what they think you accept used.
On the whole, guess bills are generally non too far off, but on the odd occasion there's a chance that y'all may exist drastically over or under charged. Either fashion, both scenarios are less than ideal so it'southward best to supply your meter readings as regularly every bit possible.
Where is my Electric Meter?
If you lot accept lived in your home for some time, finding your electric meter should exist second nature by now.
However, if you have simply moved into your current dwelling house then occasionally, it can be a bit of a chore locating your meter.
In most instances, your electric meter should be in one of the following locations:
- Exterior located in a meter cabinet or meter box
- In an under stairs cupboard
- Well-nigh the front door
- In a porch
- In the garage
- In a utility room/kitchen
- Boxed in by previous owner/tenants
If afterwards having a expect around your meter isn't obviously visible then there are a few things y'all can do.
If the belongings is a rented property then you can ask your landlord or your letting agent. They should exist able to tell you straightaway. It'southward also worth checking your tenancy agreement.
If you have just purchased the property you can try to contact the previous owner.
If this isn't possible then one trick is to go exterior and run across if you tin can see any cables running into your home from nearby poles. See where the cable runs into your property and then become inside and see if you can see any wires internally.
Generally, the meter itself should be located somewhere close to the incoming supply.
One signal to note is that there may be several cables/wires running into the business firm, one of which will be the phone line, so don't misfile this with the electric supply cable.
There should be some considerable size difference betwixt these ii cables, with the electric cable beingness a fair size bigger.
If your electrical supply isn't obviously run in from a telegraph pole, then it will probably run underground. This is typically the case on many housing estates.
Again, subsequently walking effectually your home y'all should spot information technology fairly easily and with undercover supplies the meter tends to be located externally where the supply comes out the ground or very close to it on the within.
What is a kW and a kWh?
To truly sympathize how much energy a given appliance uses and how much this could cost you, it's a bang-up idea to get a good understanding of exactly what a kilowatt and kilowatt hour is.
By understanding what each actually means you can then hands:
- See how much an appliance, tool etc could cost to run
- Place electrical goods that are expensive to run and reduce their usage
- Meet how your energy provider works out your bills
- See why information technology's a good idea to turn appliances off at the plug and non go out them on standby
- Compare prices between energy providers
Firstly we'll bargain with kilowatts (or kW). Every bit with most other metric measurement scales, kilo generally ways 1000 e.g. kilogram which is a 1000 grams, kilometer which is a 1000 meters etc. and with this in listen, kilowatts are no different. one kilowatt essentially equals 1000 watts.
Watts themselves are a measurement of power, or how much ability a given apparatus needs to run. For example, a 2000 watt or 2kW heater will need a supply of 2000 watts of power for it to work.
When it comes to kilowatt hours (or kWh), although this measurement scale is related to kilowatts, it'due south not quite the same.
Whereas kilowatts are a measurement of power needed for a given appliance to work, a kilowatt hour is simply a measurement unit that equates to the amount of free energy that it would have to run a 1000 watt appliance for one 60 minutes.
Sticking with our 2kW heater example mentioned above, as it requires 2000 watts of power to operate, it would use 1kWh of energy in just xxx minutes, or half an hour.
Similarly, if you had a modernistic 10 watt LED light bulb, it would accept 100 hours to utilize 1kWh of free energy.
How can I employ Kilowatt Hours to Calculate how much an Appliance might toll to run?
Now that we have established the differences between kilowatts and kilowatt hours, it'south at present possible to use this information to figure out how much a given appliance is likely going to toll to run.
Pretty much every appliance these days will feature a label somewhere on the particular that states the how much ability it needs to run.
A typical power rating label on the dorsum of a microwave
In one case you have located the label, make a note of the power requirements of the appliance. In this example we're going to be using a microwave. On looking at the power rating label (as you can see in the image to a higher place) information technology's an 800 watt microwave.
Now that we know how much ability our microwave is going to use, we at present need to work out how long it's going to exist used for each day. For arguments sake, we're going to say thirty minutes or 0.v hours a day.
To work out exactly how many watts-hours per day our microwave is going to utilise, nosotros so simply multiply 800w by the hours used per mean solar day; 800 10 0.5 = 400, and then in this case, 400 watt-hours per twenty-four hours
The next step is to work out our kWh figure – in this case we take our watt-hour figure of 400 watt-hours divide past 1000 watts (or a kW) and this will give us our kWh figure. To summarize, 400 watt-hours ÷ grand = 0.4kWh
At this betoken, we now take the basis of something we can work with to estimate how much our microwave is going to cost to run over a given time frame.
Again, for arguments sake we're going to wait at the cost of our microwave over a 31 day month. Firstly, we multiply our 0.4kWh by 31 days to give u.s.a. a total of 12.4kWh for the 31 days.
Next, we need to have a look at our electric current electricity pecker or contract to see how much our provider is charging us per kWh for our electricity. As an instance cost we're going to say that it'southward 0.19 pence per kWh.
All that'southward left to do now is to multiply 0.nineteen pence x 12.4kWh for the xxx days and we make it at a cost of £2.36 for our microwave for the month.
At this bespeak, you should now have a scrap more of an in-depth understanding of the differences between kW and kWh and how each tin be used to summate the running costs of a given appliance.
Depending on what meter you have will depend on how yous read your electrical meter. Equally yous tin see form the above, the standard electric meters are generally the easier to translate, just on the whole, every bit long as you learn how to correctly read your given meter, you won't get incorrect.
