Water is something most of us use everyday without thinking twice about it - but it all adds up. In the UK, the average person uses hundreds of litres of water each day, much of it in the bathroom through showers, toilets and taps - equalling to an average of 100-170 litres a day per person. But how much does that actually mean in real terms, and what does it cost you over a year?
In this blog, we'll break down the average water usage per person in the UK and explain where it all goes. You'll see how much everyday bathroom activities contribute to your total usage, what it looks like in pounds and pence, and how it scales up in a typical 4-person household. Finally, we will look at simple ways you can reduce both your water consumption and your bills without making big lifestyle changes.
What is The Average Cost of Water in The UK?
In the UK, around 60% of households now have a water meter, meaning most homes are billed based on actual usage rather than a fixed rate - however the exact percentage varies by region and water company. To make things simple, lets discuss just the average costs for metered customers.
The cost of water in the UK is based on both your water supply (clean water in) and wastewater charges, and prices vary slightly depending on your supplier. However we have looked at the most updated going rates per cubic meter of clean water and waste water from 5 different regions across the UK for you to compare.
From this data it shows that on average the West/Midlands currently has the cheapest combined rate for clean and waste water usage per cubic meter, sitting at an average of £4.18, with South/London coming close second at £4.20, then East at £5.51, North West £5.52 and the most expensive is South West sitting at around £7.71.
However one thing to bear in mind is that the cost per cubic meter is not the only price you will pay, each water supplier has their own individual fixed yearly rates which can really up the overall cost. Every water supplier charges differently, with some charging different rates based on your property type. Despite the South West costing more per cubic meter compared to the West/Midlands, the fixed rate for West/Midlands compared to the South West can be up to 17-19% more expensive depending on property type.
How Much Water Do We Use In The Bathroom?
Based on average figures from Water UK, the table below shows how much water each bathroom fixture uses, we can then use that information to calculate how much water you're really using and how much it's costing you.
Lets say the average person flushes their toilet 8 times per day, washes their hands 8 times a day for 30 seconds while leaving the tap running, brushes their teeth twice with the tap running and then has a daily 10 minute mixer shower or bath, this can equal to around 168 litres of water used per person, per day just in your bathroom alone - that's 61,320 litres of water used in a year . To put that into perspective, a household of 4 might use around 245,280 litres of water a year just in the bathroom, which is enough to fill over 1,600 baths, showing just how quickly water usage adds up over time.
What is The Average Cost of Water Usage in The Bathroom?
The bathroom is one of the biggest contributors to overall water costs, with daily activities like showering, flushing the toilet and using taps adding up over time. While each use may only cost a small amount, the total annual cost can be significant.
The visual below shows a breakdown of the average annual cost per person for each bathroom appliance, highlighting where the most water - and money - is being used.
How to Reduce Bathroom Water Usage
Reducing water usage in the bathroom doesn't require major lifestyle changes - small, consistent habits can make a noticeable difference to both your consumption and your annual costs. Since the bathroom is the largest source of water use in most homes, even minor improvements here can lead to significant savings over time.
Take Shorter Showers
Showers are one of the biggest contributors to water usage. That quick 5 minute shower can quickly turn into a 20 minute shower singing session and can add on 120 litres extra usage or around an extra 65p a day. Cutting just a few minutes off your daily shower can save litres of water each day and reduce your yearly costs.
Install Water-Efficient Fixtures
Switching to low-flow showerheads, aerated taps and dual-flush toilets can significantly reduce water usage without affecting performance. By swapping to a dual-flush toilet, they can save thousands of litres per household annually compared to older models when properly used. These upgrades are simple but highly effective.
Turn Off Taps When Not in Use
Avoid letting taps run while brushing teeth, shaving or washing your hands and face. This small habit can save a surprising amount of water over the course of a year. Leaving your tap running for 2 minutes while brushing teeth uses around 12 litres of water, by simply using for a shorter amount of time - lets say you only use the tap to rinse your toothbrush for 15 seconds - that will only use 1.5 litres of water, costing you around just £12.80 for a years worth of teeth brushing opposed to £51.10.
Fix Leaks Promptly
Dripping taps and running toilets can waste large amounts of water over time. For example - A dripping tap wastes at least 5,500 litres of water a year - enough to fill a paddling pool every week for the whole summer. Fixing leaks quickly helps prevent unnecessary usage and keeps your bills under control.
Be More Mindful of Daily Habits
Simple changes - like using only the water you need, turning off taps between uses, and being aware of how long you spend in the shower - can all contribute to lower water usage.
By making a few small adjustments, you can significantly reduce the amount of water you use in the bathroom - helping you lower your bills while also using water more efficiently.
Final Thoughts
By looking at water usage on a per person basis, it becomes much clearer how everyday routines drive both consumption and cost. When scaled up to a full household, these figures increase substantially, highlighting just how impactful small changes can be.
It's also important to remember that costs vary depending on location, water tariffs per cubic meter, fixed annual rates and whether your home is metered. In regions with higher water prices, such as the South West, the financial impact of water usage can be even more noticeable.
Ultimately, the key takeaway is that the bathroom offers the biggest opportunity to reduce both water usage and costs. Understanding where your water is going is the first step towards managing it more effectively - and reducing your bill in the process.
