How much does it cost to flush a toilet?
"There isn’t really a straightforward answer to this question," explains Tim Clarke, Head of Media atCCW(Consumer Council for Water). "There are so many variables to consider, including the type of toilet you have – single flush or dual flush – and the fact that water charges vary across the country. And bear in mind only those who pay metered charges would be affected by this, as they pay for the amount of water they use – rather than unmetered charges."
Calculations will also depends on how many times you flush your toilet in yourbathroom designeach day. According to CCW research, the average person flushes the loo around 6 times a day (which is 5 small and 1 big flush for dual flush toilets).
This information has led them to conclude the following estimates:
- a person’s average daily use of asingle flush toilet is about 25p per day or 4.16p each time they flush.
- a person’s average daily use of adual flush toilet is about 9p per day or 1.5p each time they flush.

It's clear from the estimates above that investing in a modern dual flush toilet can save you around 16p per day in water bills (which is close to £60 a year in savings). According toWaterwise'dual flush toilets typically use 4-6 litres of water per flush as opposed to the old style flush systems which use a 13 litres on average'. Ideal in the face of ever increasingwater bill rate rises.
Another money saving alternative is the modern rimless toilet (for a detailed explainer on these you can read our piece onwhat is a rimless toilet). The efficient flush technique of rimless toilets use less water than traditional models. When fitted with a dual flush, rimless models typically use between 3-4.5-litres per flush.
Should I use old bath water to flush my toilet?
As people were struggling with the cost of living last year, Money Saving Expert advised people to "flush their toilets with old bath or shower water".
The theory behind this is that it works the same way as the normal flush would, by pushing the waste down the pipe but without using any additional water from your supply. And it does actually work.
However, whether or not this will save you money very much depends on if you are on a water meter or not. Those not on water meters will find no difference in their bill if they switch to recycling bath or shower water for flushing their loo, while - in theory- those who are on a water meter should use less water. How much water will depend on how much you flush the toilet, which is likely to be dependent on how many humans you have using the toilets in your house.
Say for example you have four people using the toilet four 'single flush' times in a day, you could save yourself around 65.5p a day in toilet flushes. Whether that is worth the effort (and potential mess) is up to the individual.
