You can find out when your next ESA assessment will likely be by contacting the DWP office dealing with your claim.
Whilst there is no legal requirement to issue an ESA50 it would be incredibly rare for a reassessment to be done without one being sent to the claimant, so expect the form to be the first indication that you are being assessed again.
