From Cheadle Village Partnership meeting:

The current aim is for Tescos to open in Cheadle by the end of November, but it may be couple of weeks earlier as work is currently ahead of schedule.

The Church, which owns the site and is developing the upper rooms, is looking for feedback from the community on what could go into the upper rooms (more than you might think, apparently).  There will be open days on Fridays and Saturdays in October and a section should appear on the Church website where you can find out more information.
