yes kaz, just keep it so when we get a good freeze the growth tip isnt real wet and exposed to frost and snow, you can wrap a roll of fleece round it to protect it, i had one in a pot, kept it up against a south faceing wall in winter, which was fine for 4-5 years, i figured it was hardy, so moved it out away from the wall, they stand cold very well, but the growth tip is the most tender part in a freeze, so out in the open they are at risk, we just had a real mild winter so it might have been fine out in the open, but we cant risk it.
they do get hardier with age and size, but ya need to wait a good while, because no on actually knows at what age and size they need to be in the UK to be fully hardy, only ones i have seen in the open and looking fine after a winter or two have been 10-12' tall!
Sam, dont be complacent about it being hardy, i made the same mistake and lost mine too, i would wrap the growth tip in a good fleece for winter, and even then be wary, small date palms are not as hardy as ya think!
two palms i do know to be fully hardy even when small are : trachycarpus fortunei, chosen palm and chamaerops humilis, mediteranian palm, i have had both in the ground from 12" one is now 7' tall the about 4' they stand our weather pretty well, both are fan palms, and both can be put in a pot for a few years too.
