From 1 September Withdean Sports Complex, King Alfred Leisure Centre, Portslade Sports Centre and Stanley Deason Leisure Centre are all open and welcoming back visitors.
Moulsecoomb Community Leisure Centre and St Luke’s Swimming Pool will follow on 1 October.
Prince Regent Swimming Complex will remain closed for the time being as major Health and Safety works are underway to replace the ventilation system which is over 30 years old. During lockdown LED improvements to the main pool lighting has already been able to be completed.
Leisure centres were allowed to re-open from 25 July but many still remain closed across the country. Industry associations such as Community Leisure UK are continuing to press for government support for public leisure centres.
Safety is a top priority for visitors and staff. This means leisure centres are more expensive to run, with extra cleaning and fewer people able to use the facilities at any one time.
Councillor Marianna Ebel, joint chair of the Tourism, Equalities, Communities and Culture Committee, said: "We know how valued our community leisure centres are and how much they have been missed during the lockdown.
"Looking after our health, both mental and physical has been given new meaning during these challenging times but leisure centre operators across the country are facing a very difficult financial situation. In the light of this we are doing all we can to safely open facilities and enable them to keep open for our residents."
