No, you wouldn't, your list states the frequency range as "Digital communications" @ 70cm WL for that matter and as a secondary, look at the ISM bands for Region 1 (UK etc) and you will see that that frequency, along with the 868-869MHz is perfectly usable and would not get anybody's "arse kicked"
The only thing you have to be careful of is duty cycle and power output at these ISM band freq's (the powers that be like 10% @ < 500mW, some say 100mW depending on freq).
Portable traffic lights, motorway sign communication etc all use these kinds of technology without any prior arrangement from HAM enthusiasts, lots of things share the same frequencies, so it helps to encode it as much as possible, more common is to use a XBEE type interface these days, but all perfectly legal nevertheless, you only suffer from interference if multiple systems on the same frequency are operating the area, thats why it helps to use channels.
I have been designing systems with sub 1GHz radios for the past 5 years for the Highways Agency and they have passed every single conformity going (they've had to).
