Water Usage Calculator
How much water do I use?
Our simple water usage calculator will help you to understand how much water you might be using in your home. It gives a rough estimate of weekly water usage based on the number of times you use items which consume water, based on the number of occupants in your home.
The data in this water usage calculator uses fascinating data and numbers gathered from our report on how much water things use around your home, so check that out for more useful information.
Your numbers of for water usage may be even higher than this, because there are so many places water is used in homes, we have excluded things like brushing your teeth, washing your hands, water used in cleaning etc in our water usage calculator but we have covered many of the high water consumption items in the UK.
For more on water usage, see our guide on how to read a water meter and our water leak calculator.
As you can see from our handy water usage calculator, the numbers can add up significantly over a week and if you are interested in water conservation or simply want to potentially save money if you are on a water meter, this information can be handy. Clearly, the more occupants you have in the home, the more water you will likely use, as can be seen in the water use calculator above.
If you would like to understand how much water a certain sized tank, pond or even swimming pool can hold in water, please have a look at our water volume calculator. Also, we have a useful article explaining the signs of a water leak in your home or business.
As you can see from the water usage calculator, a water amounts add up:
Let’s use an example for water usage:
- A household with 2 adults and 2 children
- Each taking 3 baths per week and 4 showers per week
- Using the dishwasher 4 times in a week
- Using their washing machine 4 times per week
- Visiting the toilet 3 times daily each
- And using their garden hose once a week
- Are estimated to use 2,487 litres per week!
- To put that into perspective…
- If someone drinks 2 litres per day in the UK
- That’s over 3 years of drinking water used (almost 3.5!)
- We have other useful leak detection tools to help understand water leaks too
On this subject of water usage calculators, one of the things in the tool is baths and showers, we discuss these in our article about bathroom condensation problems. Plus in our guide to a bathroom leak, one of which might be a toilet leak.
How do you calculate water leaks?
Clearly, as experts in early water leak detection, we are experienced in evaluation how much water loss people are experiencing in their home or business (we do commercial leak detection too). So this kind of information and data is useful for us too. One of the key considerations is the type of water leak you have in your property.
Water leaks come in many shapes and sizes, including a few examples:
- Combi boiler leaks on your central heating network
- A leak under floorboards or underground leaks
- A radiator leak which could be in a number of places
- A ceiling leak, which brings about specific risks too
- Linked to that, a shower leaking through ceiling
As we are sure you can understand all these are different and can involve various types of water leaks, or escape of water as insurance companies classify them as often. The water could be clean mains water, sewer water, drain water or even water in your central heating pipes.
So not only is the type of water different but similarly, the amount of water. For example, as highlighted in our boiler pressure loss calculator, a pressurised boiler system might only have a finite amount of water whereas a mains water pipe leak, can have an almost endless supply of water until it is fixed.
This is why leak detection experts like us helping to find leaks can be very beneficial, and help to prevent further damage to your home. We are water damage restoration experts too!
Water Usage Calculator Benefits
We hope you found our water usage calculator useful in helping to understand how water usage adds up. Water usage calculators often surprise people as something like flushing the toilet is often done without a second thought, not realising that each time you use it, many litres of water are used.
Water conservation is a big issue in many countries, especially as production and distribution of drinking water has a carbon footprint – you can read more about this in the BBC Guide to Water Usage Impact.
We also have some interesting articles about drinking water usage and tests:

How do you calculate water usage?
You can calculate your water usage using our free water usage calculator tool. By simply entering a few details about the number of people in your home and how often you use appliances which consume water (such as dishwashers and washing machines) we give you a quick estimate of your usage which can be really useful, especially if you are looking to reduce water consumption.
How much water does a family of 4 use per day UK?
There are number of factors which will contribute to how much water a family of 4 uses per day in the UK, especially as the amount of baths and showers people take will make a difference, as will using the toilet etc. Factoring in things such as washing machines, dishwashers and other general usage, it would be around average to be in the region of 200 to 400 litres per day, possibly more for some.
How much is 1,000 litres of water?
To help visualise how much 1000 litres of water is, think of a cube 1m x 1m x 1m and that is 1,000 litres of water (also known as a cubic metre of water or M³). Meters cubed are often used as the scale on water meters to measure consumption. Clearly, 1,000 litres is a lot of water but an average UK household may get through more than this in a week and one bath could be 100 litres alone.
