Cheshire West and Chester Council has confirmed that the sites will open on Tuesday, May 4.
The Chester facility is at Dee View Hub in Europa Court, off Bumpers Lane (CH1 4NP) and will operate from 3-7pm, Monday to Friday, and from 8am to noon on Saturday.
The Ellesmere Port centre is based at the town's library in Civic Way operating during normal library opening hours.
Both of these sites have parking available nearby.
The "Community Collect" service offers free packs of Covid-19 test kits for residents to do at home as part of the Government recommendation that we all test twice a week, regardless of whether we have been vaccinated or not.
