Are you unsure how to read a water meter and need some advice on taking a water reading? Our helpful guide will help you better understand your water meter reading.
Why should you provide a water meter reading?
Regularly taking a water meter reading lets you keep an eye on how much water you're using and helps your water company provide accurate bills. Similar to submitting an electricity meter reading, there are many advantages to providing a water meter reading:
- Ensures you are being charged the correct amount for your water usage.
- Assists you stay within a budget.
- Helps detect potential water leaks sooner.
- Shows your water consumption habits.
- Avoids disputes with your water supplier.
Where do I find my water meter?
Your water meter can either be located outdoors or indoors. If the water supply pipe is shared with other households (like in flats or apartments), the meter is most likely to be indoors. On the other hand, if the water supply pipe is not shared with other households the preference is for the water meter to be installed outdoors.
Outdoor water meter
An outdoor water meter is often situated very close to the stop valve. These are frequently found on your property close to the footpath. Keep an eye out for a small metal or plastic cover in the ground. Simply lift this cover (preferably with a tool like a screwdriver) and you should be able to see another plastic-type cover, this is there in order to protect your water meter from frost. Remove the protective covering and you will find the water meter.
Indoor water meter
If you can't find a meter or plastic cover near the footpath, chances are that your meter is installed indoors. Most water suppliers will attempt to install the water meter where the water supply enters your property. This is often located under the kitchen sink or in your garage.
In most large buildings, your water meter will be in a utility room much like the one depicted to the right. To determine which water meter belongs to your home, you will have to verify the serial number on the meter and make sure it matches the number on your water bill.
What does a water meter look like?
Before you read your water meter, it is important to find out whether your water meter is a traditional water meter or a smart water meter. The UK government first introduced smart water meters back in January of 2016. Most households still use the traditional water meter. We will delve into the differences and benefits of either meter so you have the knowledge to identify what meter you have.
Traditional water meter
The vast majority of water meters in the UK are round in shape and are connected to the water mains piping. On the surface of your meter, you will notice either four or five black digits and two red digits, often accompanied by a small dial. You can find the serial number of your water meter on the outer rim of your meter. Your meter serial number should consist of nine digits.
Smart water meter
Like traditional water meters, most smart water meters are also round in shape and slightly larger than a traditional water meter. There is a digital screen that shows multiple numbers and as many as three decimal points after a coma. The serial number of a smart water meter is located above the bar code, which can be found in the inner portion of the meter underneath the digital display.
How to read a water meter
Now that you have identified what type of water meter you have, let’s have a look at how to read your water meter.
Firstly, it is important to look where your water meter is located and make sure the serial number matches the number on your water bill. Ensure that any coverings protecting the meter are open or removed, some water meters have a lid; if there is one, open it so you can see the meter face.
Since there are two types of water meters, we will look at how to read a water meter for each type. We’ll cover which numbers you read on a water meter and explain water meter dials in more detail.
How to read a traditional water meter
Your water meter should display either four or five black digits followed by two red ones. Red numbers are decimal points to your usage. Simply read the black numbers from left to right and ignore any red numbers at the end. Your water company does not require the red numbers in order to read the meter correctly.
How to read a smart water meter
You shouldn't have to read a smart water meter. The whole purpose of having a smart water meter installed is for your local water supplier to be able to obtain the water meter readings automatically making things simpler for the consumer. You may want to look at your smart water meter reading to ensure you are being billed accurately.
Much like a traditional water meter, simply read the digital numbers from left to right until the comma. You can ignore any digits after the comma.
How to submit a water meter reading
Once you have your water meter reading, you can submit the figures to your water supplier via your online account, by phone, or even by post. In order to provide a meter reading, you may need to provide the following information:
- Your customer reference number. This is the eight or 10 digit number shown on your water bill.
- Your payment reference number. The reference number normally consists of 13 digits and is located on your water bill.
- Your name as it appears on your water bill.
- Your water meter reading.
