Water meters found to immediately reduce water use

People use 16.5% less water when they have a water meter in their homes - research from the University of Southampton has found.

The study was based on a five-year programme to install nearly half a million water meters in the south-east of England.

This reduction is far more than the national average of ten per cent and is mainly achieved very quickly after a meter is installed.

Overall, we find a strong decrease in water consumption due to the UMP. But what is particularly remarkable from a behavioural perspective is that households start reducing their consumption as soon as the meter is installed – even though they do not immediately have financial incentives to do so, due to the three month ‘grace period’ between installation and switch of contract."
