The hosepipe ban will be lifted for Thames Water and Southern Water customers tomorrow but will remain in place for others.
It came after an 'extraordinary' amount of rain eased the water shortage in the South and East.
The ban came into place on April 5 after the driest two-year period on record.
But rainfall in April was more than two-and-a-half times higher than average, and it has continued to come down in May and June.
Thames Water's sustainability director Richard Aylard said: "Since we imposed the temporary use ban just over two months ago, we have received an extraordinary amount of rain.
"We are really pleased we can now lift the ban but, with groundwater levels still low and the possibility of a third successive dry winter, we still need to be careful.
"We don't need a ban, but we do need to ask everyone to keep on using water wisely."
South East Water (SEW) and Veolia are continuing their bans.
Both rely heavily on groundwater supplies which take longer to be penetrated by rain fall.
SEW Asset director Paul Seeley said: "As soon as we are confident the groundwater sources have recovered we will remove the restrictions."
