UHF 584-607MHz, license required UK?

Hi all - newbie question here running IEMs for 4pc indie band on festival circuit and small venues. Mostly playing in the UK but occasional Europe dates.

Whilst assessing options I reckon I'm probably looking to get the LD Systems MEI 1000 G2.

Various different options are available, Ch38 and Ch70, but not sure where this 584-607MHz ('B5') version falls. Ofcom PMSE info wasn't specific enough and I haven't found any info about licensing in this band. Anyone have any pointers as to whether this is allowed in UK/EU etc?

LD Systems info sheet says it's ok but this band isn't really mentioned on the Ofcom website.

I'm aware that that Shure & Sennheiser are better and industry standard. However we are keen to make the switch ASAP to wireless in-ears for at least 2 of us and these are definitely outside our price range for now (although we'll be upgrading down the line). Walks the line between affordable and well-reviewed, plus has specific frequency selection instead of pre-set channels.

Thanks in advance x
