Outdoor swimming pools and lidos have been allowed to open since the end of last month under Boris Johnson's roadmap for easing of coronavirus lockdown restrictions.
But indoor pools - and gyms - remain shut under the rules outlined by the Prime Minister for a few more days.
This is set to change, though, from Monday when non essential shops and beauty services also reopen, along with outdoor hospitality.
Indoor leisure, including gyms and pools, are reopening from April 12, under step two of the roadmap.
The roadmap states: "Indoor leisure and sports facilities will be able to reopen for individual exercise, or exercise with your household or support bubble."
Swimming lessons for children will also be able to resume from this point. But over 18s will not be permitted to join in until Step 3, which is currently scheduled for Monday 17 May.
Swim England's Chief Executive, Jane Nickerson, said: “It’s fantastic news that indoor pools will be allowed to open again from Monday 12 April.
“It’s a date that we have been looking forward to for some time and it will be a welcome relief to the millions of people that have been denied the opportunity to swim, dive, play water polo or enjoy artistic swimming to finally have that conformation.
“Our club members will be counting down the days and hours having desperately missed taking part in the aquatic sports they love, while recreational swimmers and those who rely on pools to remain physically active will be thrilled to get back in the water once again."
The four tests that must be passed before each stage of the restrictions are easing are as follows:
