Water companies lost over a trillion litres of water last year because of leaks.

UK water companies: 10 worst suppliers for leaks as hosepipe bans come into force - including Thames Water

As the hosepipe ban comes into effect across parts of England we reveal which water companies have lost the greatest amount of water to leaks in the last year.

Water companies are losing millions of litres of water every day because of leaks – as gardeners across England face £1,000 fines for using hosepipes.

NationalWorld analysis of Ofwat data found over a trillion litres of water was lost through broken or cracked pipes in England last year – enough to water 4.5 billion gardens for 15 minutes apiece, based on one hose pipe using 1,000 litres per hour on average.

The amount lost to leakage was also the  equivalent of almost half a million Olympic sized swimming pools.

The analysis comes as Thames Water becomes the latest provider to announce a hose pipe ban after a summer of record-breaking temperatures. The ban comes only days after one of its own pipes burst in Islington, flooding the local street and damaging properties.

How much water has your local provider lost to leaks in the past year? Here we reveal which companies have lost the most water relative to the length of piping in its supply network.
