Please be so kind as to turn off the Caps Lock.

There is a commercially-available UHF radio system operating in the 446MHz region, labelled "PMR" - Private Mobile Radio, and 2-way radios are available commercially starting at around £35GBP per pair. No licence is needed for operation. These things can be found at major home improvement outlets and major stationery and business equipment retail outlets. Numerous on-line traders stock them as well. Try http://uk.rs-online.com/web/search/searchBrowseAction.html?method=retrieveTfg&binCount=39&Ne=4294957561&N=4294964533+4294954226 (usual disclaimer).
