The latest prediction from Marco Langbroek is that re-entry will occur around 06:30 UTC tomorrow, May 10, with an uncertainty of +/- 4.1 hr:

The latest TLE from space-trak (dated March 9.655) has perigee down to 127 km. The spacecraft has passes over the UK on May 10 as follows (times are UTC):
04:34 – Low elevation in the southeast.
06:05 – Almost overhead
07:36 – Almost overhead
09:06 – Low in the southwest.
All of these are in daylight so if it does re-enter over the UK we are unlikely to see it but, if the sky is clear it might be worth looking when it comes over.
