A Practical Guide on How to Read Your Water Meter

Learning how to read your water meter is a simple but powerful skill for tracking usage, spotting costly leaks early, and making sure your bills are accurate. Think of it as a quick health check for your home's plumbing and your wallet.

Why Reading Your Water Meter Matters

Getting to grips with your water meter is one of the fastest ways to take control of your utility bills. This simple check-up helps you see exactly what your household is using and can flag expensive leaks before they spiral into serious damage.

When you understand your usage, you can be confident that you’re only paying for the water you've actually used. It also puts you in a much stronger position if you ever need to challenge an unusually high bill from your supplier.

Knowing your consumption patterns also shines a light on where you can make savings. For example, many people are surprised to learn about how much running a dishwasher costs. Regular meter readings will show you the direct impact of using your appliances more efficiently. Ultimately, this skill empowers you to be a smarter, more proactive homeowner.

Finding Your Water Meter and Getting Ready

Before you can read your water meter, you have to find it. In the UK, it’s usually outside your home near the boundary of your property. Look for a small plastic or metal cover on the pavement or in your garden, often marked with ‘Water’.

You might need a flat-head screwdriver to gently open the lid. Don’t be surprised if it’s full of leaves or soil; just clear out any debris so you can see inside.

Once the cover is off, you’ll see the meter itself, often next to an isolation valve or stopcock. This tap controls the water supply to your house. It’s always a good idea to know where this is. In fact, you can learn how to turn off your water mains in our separate guide – a handy skill for any homeowner.

Understanding Different Water Meter Displays


Once you've located your meter, the next step is reading its display. Thankfully, it’s simpler than it looks. Most UK homes have one of two main types: a traditional analogue meter or a more modern digital one.

How to Read Common Water Meters

Here's a quick guide to understanding the two most common types of water meters in UK homes.

Meter Type What to Look For How to Record Your Reading
Analogue Meters A display that looks like a car's odometer, with a row of numbers and often a few small, spinning red dials. Your water company only bills you for cubic metres (m³), so just write down the numbers shown in black and white. You can ignore any numbers in red or on the red dials, as they’re for testing.
Digital Meters A straightforward electronic LCD screen that shows a clear numerical reading. No dials or different colours to worry about. Simply jot down all the numbers you see on the screen from left to right to get your reading.

The Rise of Smart Meters

While classic analogue and digital meters are common, advanced smart meters are gradually being rolled out. According to the latest findings on UK water resources from gov.uk, only about 12% of households in England have one, but their impact is significant.

These meters are a game-changer because they send readings automatically, often every half an hour. This provides a constant stream of data that makes it easy to spot unusual patterns, like a sudden spike in usage that could point to a leak.

How to Calculate Usage and Check for Leaks

Once you've got your meter reading, working out your usage is simple subtraction. Take your current reading and subtract the previous one. For example, if your meter now shows 5678 and your last reading was 5500, you’ve used 178 cubic metres of water.

Your meter is also one of the best ways to spot hidden plumbing problems.

Pro Tip: To check for a leak, turn off everything that uses water – taps, washing machine, dishwasher, etc. Note the meter reading, then leave everything off for about an hour. If the number has moved when you check again, you likely have a leak.

This test can catch anything from a dripping tap to a more serious hidden pipe issue. A tiny leak can waste thousands of litres over time, running up your bills.

If you perform this test and notice other signs like water leakage through a ceiling, it’s a clear signal to act fast. Our expert plumbers can find and fix leaks quickly, saving you money and hassle.

When Should You Take a Meter Reading?

To get a handle on your water usage, consistency is key. Try to take a reading on the same day each month. This simple routine helps you build a clear picture of your household’s water habits and makes it easier to spot unexpected spikes that could signal a leak.

Having accurate, monthly records puts you in a stronger position if you ever need to challenge an unusually high bill.

There are a couple of other crucial times to take a reading. Make sure you do one the day you move into a new property to ensure you’re not paying for the previous occupant's usage. Likewise, always take a final reading when you move out to close your account correctly.

Common Water Meter Questions Answered

Here are a few common situations you might encounter and what to do about them.

What if My Meter Reading Hasn't Changed?

If your meter reading is the same as last time, especially after a week of normal water use, it could be stuck or broken. First, check that your home's main stopcock is fully open. If it is and the meter still isn’t moving, contact your water supplier. The meter is their responsibility, so they will send an engineer to check it and replace it if needed, free of charge.

Why Is My Water Bill So High if There's No Leak?

A surprisingly high water bill can be baffling. Before you panic, think about what’s been happening in your household lately.

  • Seasonal Use: Have you been watering the garden more or filled a paddling pool?
  • New Appliances: A new power shower, dishwasher, or washing machine could be using more water than your old one.
  • Having Guests: A few extra people staying over can easily push your water consumption up.

If none of these apply, run through the leak check process one more time to be certain you haven't missed a slow, hidden drip somewhere.


If you’ve ruled out leaks and can’t account for high usage, there might be a hidden plumbing issue. The expert plumbers at Go Assist are brilliant at diagnosing and fixing tricky problems. You can find out more and book a reliable engineer on our website.
