Reading Electric Meters – How to Take Readings From Different Types of Electrical Meters Including Standard, Digital, Dial and Economy 7 and 10 Meters
If you accept never taken an electric meter reading earlier it can be quite confusing. Using the guide below, you will learn all near the different types of electric meters that include standard electrical meters, the digital meters, dial meters and the 2 different Economy 7 and 10 meters. Yous will also learn how to calculate how much a given appliance could cost to run.
Electric meters or energy meters as they are likewise known are installed in pretty much every home 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 past the occupants of the bounds to ability electrical appliances such as TV'south, fridges, freezers and other household appurtenances so that their given energy supplier gas charge for what'south been used.
The meter itself measures electrical usage in "units". With virtually meters, one unit of electricity consumed is equal to one kilowatt hour (or kWh for brusk) or if 1000 watts of power is fatigued consistently over the period of ane hour, this equals 1 kWh or 1 unit of measurement.
How to Read an Electric Meter
Now that we have looked at the various different types of electrical meters and how they display electric usage, information technology's now time to have a expect at how yous actually take a meter reading from each dissimilar blazon of meter.
How to Read a Standard Electric Meter
Reading a standard electric meter to give your energy supplier a meter reading is a adequately straightforward chore. All you lot have to practise is provide your supplier with the numbers in black or on a blackness surroundings, reading them from left to right.
Yous may besides notice that in that location are numbers in scarlet or on a red background. These are effectively decimals and tin be safely ignored as your supplier is just interested in the whole numbers.

How to Read a Dial Electric Meter
These are arguably the trickiest types of electric meters to read due to the number of dials and more importantly the direction in which each punch is read. This is normally the part that catches people out.
As nosotros have mentioned in a higher place, each dial alternates in terms of which direction information technology's read in. Nigh meters offset with the offset dial on the left being read in a clockwise management and the side by side 1 to it'southward correct being read in an anti-clockwise direction and then on.
Substantially, the starting time, third and 5th dials are read clockwise, while the second and fourth dials are read anti-clockwise.
A good indicator in terms of which way the dial should be read is which way the numbers effectually 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 style around from 0 to 9, at which signal it and then starts again.
There are too a few rules to be aware of when reading the dials:
- Always start with the dial furthest to the left and then read across to the right
- If the dial manus falls betwixt 2 numbers go with the lowest number e.thousand. if it falls half style betwixt viii and 9, go with 8
- If the punch hand falls between 0 and 9 on any punch then always get with the ix
- If yous have a reading of 9 on any of the dials and so y'all will need to reduce the reading of the dial to it'due south left by 1 due east.g. if the fourth dial reads ix and the tertiary punch to its left reads 3, this numbers needs reducing to 2
- Yous don't need to record the concluding dial. These are ordinarily coloured crimson or labeled one/x

How to Read an Electronic or Digital Electric Meter
Again, every bit 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 indicate including any zero values.
Whatever numbers to the right of the decimal point can exist safely ignored.

How to Read Economy 7 and Economy 10 Electric Meters
As we take discussed above, Economic system 7 and Ecomony 10 meters feature ii displays if their the older type mechanical meters or if you have a digital meter, there will be meter view select push or the meter itself will simply alternate between reading views.
As we have stated above, if in that location is any mention of "multirate" on the meter housing then yous can be certain that the digital meter y'all are dealing with is indeed an economic system 7 or 10 meter. However, if information technology mentions single rate so it's simply a standard digital meter on a standard tariff.
If you lot'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-peak readings.
Most digital multi-charge per unit meters will simply alternating their brandish to bear witness either the on-peak or off-meridian reading. If you lot spotter information technology for long plenty you should see it alter.
The given reading y'all are viewing will exist signified past the pocket-size number to the left of the actual reading – either 1 or 2
Just note down each reading onto a slice of paper and so transfer them to your suppliers chosen method of capturing the readings. In most cases, this volition exist an online portal of some kind.
In the example that yous have an older mechanical meter, both readings should be displayed and like shooting fish in a barrel to run into. Simply note each one downwards and transfer them to your supplier for billing.

How to Read a Prepayment Electrical Meter
Every bit the proper name would suggest, if you have a prepay meter and so you have to pay for your electricity upfront earlier you lot use it and due to this, chances are that your supplier volition not require a meter reading, but on the odd occasion they may practice.
If they do, but locate your meter and view the digital LCD display. In the majority of cases, the brandish will exist set past default to testify the remaining credit on the meter, merely there should too be a push button somewhere on the front that will allow you to change the default view and show full usage.
Only press the button to ringlet between each view.
If still, you cannot see any buttons then y'all will need to consult your supplier
How to Read a Smart Meter
This is a flake of a pull a fast one on equally the respond to "how do yous read a smart meter" is yous don't, that'due south essentially one of their principal plus points.
Well, I approximate that's not strictly true as if you lot do have a smart meter, and so you should be checking the energy usage in your home as often as possible so that y'all can come across what appliances are using the most and when demand inside the domicile is at its highest.
From the perspective of reading the meter to become a reading to give to your supplier and so that they tin bill y'all for your usage, then this is certainly not required as smart meters feed usage data directly to your supplier, without the need for you to supply it yourself.
However, if you do desire to view your total usage in kWh, so this is certainly possible, but accessing the information volition depend on the type of meter y'all accept:
- Smart Meter with Keypad: Press 9 on your meters keypad and y'all should then see some letters appear, normally along the lines of IMP KWH. This will be followed by a serial of 8 digits that shows your full usage figure
- Smart Meter with ii Buttons: Press the button labeled Display Select or sometimes but Display. The meter should so 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 press the A button until y'all see something similar to "TOTAL ACT IMPORT" and the serial of digits below followed by kWh are your usage numbers
- Smart Meter with three Buttons: Just press the middle button until you see a series of numbers preceded past kWh and this volition be your total usage figure
- Smart Meter with Orangish Button: Press the orangish button and you should then B

Reading Economy 7 Smart Meters
Smart meters are also available for Economy 7 and some economy 10 tariffs.
If you take a smart meter with a key pad and economy seven, press the number 6 button until you lot can see "IMP R01". The digits preceding this should be total usage for off-peak hours.
To view your on-elevation usage, simply press the number 6 push once more until you see "IMP R02" and the following numbers will state your on-peak usage
If yous have a three button meter, press the center button until you encounter R1 and R2. R1 should indicate your off-peak tariff usage and R2 should state your normal rate of on-tiptop usage.
Note: In lodge to access your total usage figure in kWh, you will need to utilise the smart meter itself and not the in-home display unit of measurement.
One final bespeak to be aware of in terms of your electrical meter is that every meter installed in the UK has it's own MPAN number (supply number or Southward-Number equally 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 form to submit your meter readings, it's a adept idea to as well cheque the MPAN number quoted on the paperwork or you online portal against your ain meter just to brand sure they are the same.
What Unlike Types of Meters are There?
The type of meters used to measure electricity consumption in a given property or building vary greatly around the world, but here in the UK there are essentially six unlike type of electricity meter.
The type of meter that is used will very much depend on the requirements of the user:
- Standard Electricity Meter: The standard electricity meter is the nigh popular type of meter and features in the majority of U.k. homes. It's a adequately 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

- Dial Electricity Meters: This blazon of meter operates in a like way to the standard meter, but instead of a line of numbers you lot accept a serial of dials that look like mini clocks. To misfile things a little more, each dial normally turns in a different direction, either clockwise or anti-clockwise

- Digital Electricity Meters: Again, pretty similar to the standard electricity meter, merely instead of have a mechanical dial brandish, you have an LCD brandish. I point to note is that if at that place is any mention of multi-rate anywhere on the meter and then the chances are this volition be an economy vii or 10 meter, but if single rate is mentioned and then chances are this is merely a standard digital meter
Modern standard digital electric meter
- Economy seven and Economy 10 Electrical Meters: In well-nigh cases economy seven and ten meters are similar to the standard electric meters, in that they display usage in kWh via a mechanical dial, but instead of having 1 dial display you will have two. Economy 7 and economy ten tariffs charge different rates per kWh for on-pinnacle and off-tiptop electricity usage, and so one punch is for on-peak usage and the other dial is for off-superlative usage
Economic system 7 electric meter with dual mechanical dials
- Prepayment Electricity Meters: As the name suggests, this type of meter requires the user to pay for their electricity in accelerate as opposed to paying for what has been used. In times past, prepay meters operated on coins (some of you may recall this) but today a card or key is used to purchase credit. In terms of display, prepay meters are mostly digital and characteristic a button that tin can modify the brandish from remaining credit to total usage

- Smart Electrical Meters: The smart meter is very much at the cutting edge of electrical metering. They can accurately measure existent-fourth dimension electrical usage and too many other things. Smart meters besides communicate straight with your supplier so you don't take to worry nearly supplying meter readings and they too do away with estimate billing so you are really charged for what yous use every bit opposed to what your supplier things you lot might utilize
Smart electric meter
The type of meter that works best for y'all volition very much depend on how and when you employ the electricity in your home.
If you lot live in a adequately busy firm, where many people are in and out for almost of the day then you lot're going to desire a constant supply of electricity at a good rate.
In light of this then a standard meter, dial meter, digital meter or smart meter coupled with a competitive fixed rate electrical tariff volition probably exist the way to go. With the emergence of and so many comparision sites over the final few years, it's now very easy to compare energy suppliers and the tariffs they have on offer and go the best deal for you.
If however, the majority of your electrical usage will exist during off-peak nighttime time hours, then an economic system vii or economy 10 tariff and accompanying meter may exist the best solution for you.
Why exercise you Need to Supply Electrical Meter Readings?
If you have a smart meter, then supplying meter readings to your energy supplier is not needed as the meter itself does this for you.
However, if you don't take a smart meter, and so you will demand to provide your supplier with your electric meter readings yourself.
Ideally, you lot should provide readings at least every 3 months or fifty-fifty better, every month if you can. This will enable your electric supplier to pecker y'all much more accurately as they will have a much ameliorate idea of your usage.
In the upshot that you don't supply your readings regularly then your supplier volition provide yous with an estimate neb. This means that they volition bill you on what they think you have used.
On the whole, judge bills are generally not too far off, but on the odd occasion there'south a run a risk that you may be drastically over or under charged. Either way, both scenarios are less than ideal and then it's all-time to supply your meter readings as regularly as possible.
Where is my Electric Meter?
If you accept lived in your dwelling for some fourth dimension, finding your electric meter should be second nature by now.
Notwithstanding, if you have just moved into your current domicile 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
- Most the front door
- In a porch
- In the garage
- In a utility room/kitchen
- Boxed in by previous possessor/tenants
If after having a look around your meter isn't obviously visible then in that location are a few things you can do.
If the holding is a rented property then you lot tin enquire your landlord or your letting amanuensis. They should be able to tell you straightaway. Information technology'southward as well worth checking your tenancy agreement.
If you have just purchased the property y'all tin can try to contact the previous possessor.
If this isn't possible and so one trick is to go outside and run into if you tin can see whatever cables running into your home from nearby poles. Meet where the cable runs into your belongings and then go within and run across if you can meet any wires internally.
More often than not, the meter itself should be located somewhere close to the incoming supply.
One signal to note is that at that place may be several cables/wires running into the house, one of which will be the phone line, so don't confuse this with the electric supply cable.
There should be some considerable size difference between these two cables, with the electric cable beingness a off-white size bigger.
If your electrical supply isn't obviously run in from a telegraph pole, so it will probably run underground. This is typically the instance on many housing estates.
Once more, after walking around your home you should spot it fairly easily and with underground supplies the meter tends to be located externally where the supply comes out the footing or very shut to it on the inside.
What is a kW and a kWh?
To truly understand how much energy a given apparatus uses and how much this could cost you, it's a neat idea to become a good understanding of exactly what a kilowatt and kilowatt hour is.
By understanding what each actually means you can and so easily:
- See how much an appliance, tool etc could toll to run
- Identify electrical goods that are expensive to run and reduce their usage
- See how your energy provider works out your bills
- See why it'south a good idea to turn appliances off at the plug and not leave them on standby
- Compare prices betwixt energy providers
Firstly we'll deal with kilowatts (or kW). As with virtually other metric measurement scales, kilo more often than not ways 1000 eastward.chiliad. kilogram which is a 1000 grams, kilometer which is a 1000 meters etc. and with this in mind, kilowatts are no different. i kilowatt essentially equals g watts.
Watts themselves are a measurement of power, or how much power a given apparatus needs to run. For example, a 2000 watt or 2kW heater volition 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, information technology's not quite the same.
Whereas kilowatts are a measurement of ability needed for a given appliance to work, a kilowatt hour is simply a measurement unit that equates to the amount of energy that it would take to run a 1000 watt apparatus for one hour.
Sticking with our 2kW heater example mentioned above, equally it requires 2000 watts of ability to operate, it would use 1kWh of energy in merely 30 minutes, or half an hr.
Similarly, if you lot had a modern 10 watt LED light bulb, it would accept 100 hours to use 1kWh of energy.
How can I use Kilowatt Hours to Calculate how much an Appliance might cost to run?
Now that we have established the differences betwixt kilowatts and kilowatt hours, it's now possible to utilize this information to figure out how much a given appliance is likely going to price to run.
Pretty much every appliance these days will feature a label somewhere on the item that states the how much power information technology needs to run.
A typical power rating label on the back of a microwave
Once 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 ability rating label (as you can run across in the image higher up) it's an 800 watt microwave.
Now that we know how much power our microwave is going to utilize, we now need to work out how long it's going to be used for each solar day. For arguments sake, we're going to say xxx minutes or 0.v hours a day.
To work out exactly how many watts-hours per day our microwave is going to use, we then simply multiply 800w past the hours used per day; 800 x 0.5 = 400, so in this example, 400 watt-hours per day
The side by side step is to work out our kWh figure – in this instance we take our watt-hour effigy of 400 watt-hours divide by chiliad watts (or a kW) and this volition requite us our kWh effigy. To summarize, 400 watt-hours ÷ m = 0.4kWh
At this betoken, we now have the ground of something nosotros tin can work with to estimate how much our microwave is going to cost to run over a given fourth dimension frame.
Once again, for arguments sake we're going to expect at the cost of our microwave over a 31 day month. Firstly, we multiply our 0.4kWh by 31 days to give us a full of 12.4kWh for the 31 days.
Adjacent, nosotros demand to have a wait at our electric current electricity bill or contract to see how much our provider is charging u.s.a. per kWh for our electricity. As an case cost nosotros're going to say that information technology's 0.xix pence per kWh.
All that'south left to exercise at present is to multiply 0.19 pence x 12.4kWh for the 30 days and we arrive at a cost of £2.36 for our microwave for the month.
At this indicate, you lot should at present have a bit more of an in-depth understanding of the differences between kW and kWh and how each can exist used to calculate the running costs of a given appliance.
Depending on what meter you accept will depend on how you read your electric meter. As you can run across form the above, the standard electrical meters are more often than not the easier to translate, only on the whole, equally long as you learn how to correctly read your given meter, you won't go wrong.
