Thanks.
Had a quick look at flightradar and I think it seems to be like that:
5x Bristol (2x ERJ135, 3x ERJ145)
3x Munich (1x ERJ135, 2x ERJ145)
3x Brussels (3x ERJ145, 2x for Brussels Airlines and 1 could be also be based in East Midlands instead of Brussels, not sure)
1x Newcastle (ERJ135)
1x Aberdeen (ERJ145)
1x Orebro (ERJ145 for LOT)
1x Karlstad (ERJ145, flying only the route Karlstad-Jönköping-Frankfurt)
1x Birmingham (ERJ145, new)
1x Bremen (ERJ145, flying Airbus shuttle between BRE and TLS and as well SN flights between BRE and BRU)
1x ERJ145 (G-RJXI) has no movements since more than one week
