I’ve recently discovered that OFCOM changed some of the PMR 446 restrictions. Primarily OFCOM have removed the demarcation between analogue and digital frequencies in the 446.0 and 446.2 MHz range. So the 16 channels can be used for either FM or DMR subject to the usual restrictions on power and antenna etc.
These changes have been reflected in an update to the codeplugs published on this site as I know many people monitor this band. There are now separate zones for PMR 446 and DMR 446. For DMR I’ve used Talkgroup 9, Colourcode 1 and Timeslot 1. This can be easily changed in CPS to suite local requirements.
