I think EARS may have it wrong somehow, or at least they are not communicating the information very well, GMRS/FRS have never been allowed to be used in The UK before as we have the crummy by comparison PMR446 service and some of the GMRS/FRS overlap other users in The UK.
GMRS frequency 462.5625 is used by the Fire service which is GMRS Channel 1. They also use GMRS frequencies 462.5875 & 462.6375
They also use 462.5375 (which is close but not GMRS)(Full list of UK Handheld Firefighter Frequencies here)
The 467 frequencies also overlap UK Media/Outside Broadcasting frequencies and on ship handhelds, this in itself must cause interference as American tourists are famous for taking their GMRS radios on cruises, ferries, holidays and such.
As far as I know GMRS/FRS radios can only be used in Canada (without a licence) or in The US (Licence needed for GMRS frequencies but not FRS). That being said, in Ofcoms new allocations there seems to be a gap from 462.5 to 463MHz although the usual allowance for ships and media is there on the FRS 467 channels. I've never heard of a 5 year GMRS/FRS licence for Europe before though and I'm sure they have it wrong?
