I guess its time to come back out of "Lurk Mode", I've not had the pleasure of hunting deer in Britain as I was only 17 when I immigrated to Canada, but while here I have had done lots, I have been fortunate enough to take many deer plus a bull moose and a bull elk Any way my point is I've skinned a few. The sooner you get the hide off the better! In particular if it is very warm or very cold. If you cant get the carcass some were to cool it its important to get as much body heat released as possible so take its coat off. If its Below freezing the hide quickly becomes very hard to remove in particular on the lower legs so get that part done quickly. They can be skinned either hanging or on a table/ground either way you will find it much easier if you work from the head/neck down, When "opening the animal" try to make all possible cuts from the inside towards the outside so as not to cut hair which will dull your knife and get on the meat. If you have to move it somewhere after skinning it rap the carcass in an old bed sheet it will keep it clean and keep flies off if its warm out.
