Meter readings

Meter readings are really important because they tell us how much energy you’re using.

Submitting a meter reading is easy, there are just a few things you need to know. Take a look below.

New customers

You need to submit meter readings the day before your official supply start date, on that date, or within 5 days after. We’ll send you an email just before your switch date. Just click the link in the email to submit your first meter readings. Or give us a call on 0800 092 0202.

Existing customers

We’ll send you an email reminder every month with a link to submit your meter readings. Or submit them online in your Flow account. You can always call us too, on 0800 092 020. Please submit your readings near the end of the month and only once a month.

Got a Smart Meter?

If you have a Smart Meter installed, please remember that we can’t currently receive your smart meter readings so you’ll need to submit them in the usual way. Please read our guide to help you read your smart meter.

How to read your energy meter

Electricity meters

There are a few different kinds of electricity meter and they are read in slightly different ways.

Simply enter all six numbers on your meter, including the number furthest to the right (usually, but not always red). If the number starts with a zero, include this too.

The reading above is therefore 04267.3


A two rate meter allows you to enter two different figures. You’ll have this kind of meter if you’re on an economy tariff. The Low rate is your night or economy rate. The Normal rate is your day or standard rate. Again, just provide us with the 6 digit number from left to right including the last number (usually in red). That means that the top reading here would be 67437.1 and the bottom reading would be 32554.0.

Sometimes, meters showing two rates are digital and only have one display. Different types of this kind of meter work in different ways. You’ll see an identifier for the rate on the left hand side. This will usually be numerical – for example, rate 1 and rate 2. Rate 1 will be your low or night rate, rate 2 will be your normal or day rate. Either the display will change automatically every few seconds to show the two rates. Or you’ll need to press the small button on the meter to see the rate that isn’t currently showing. Then just read the number as it shows, including all the digits (although please exclude the rate identifier.


Dial meters need to be read left to right and each dial represents a separate number. Each dial actually turns in the opposite direction to the one before it. So if the pointer on the dial is turning clock wise the next dial should turn anti-clockwise. Every dial revolves from 0-1 and will pass through 9 before cycling round again. But whichever way they turn the numbers passed will always run in the same order – so the pointer will pass 1, then 2, then 3 and so on.

If the pointer is between two numbers always record the lower number. If the pointer is directly on a number take that one. So in the picture the reading is 26730.6 (include the small dial).

If the pointer falls between the 9 and the 0 make a record of 9 and reduce the reading you’ve already taken by one. So, for example if you’ve originally recorded 5 as the number reduce it to a 4.

Gas meters

There are a few different kinds of gas meters and they are read in slightly different ways.


Dial meters need to be read left to right. Each dial represents a number. The pointers on the dials spin round in a clockwise direction. The number you’re looking for is the number the dial has just passed. So, if the pointer on the dial is between 2 and 3, the pointer has just passed 2 so you need to record number 2. Therefor the reading for the meter above is: 02673.


With this kind of meter, please simply read the 5 numbers from left to right. Ignore the numbers after the decimal point, whatever colour they are. The meter reading here would therefore be: 00366

imperial meter

One of the simpler meters! Just read the 4 numbers from left to right, ignoring the smaller numbers which may be in red. So the reading here would be: 6375.
