My two cents,,
I assume location SW= the UK but if not some of this may not apply !
De-icing light Aircraft is a drag so if you can avoid doing it by keeping the Plane in a hangar overnight or, if the plane has to be parked outside put it in a position where the rising sun (yes we do get sun in winter, Honest) will melt the Frost. Tip, turn the Plane into the Sun so that the Windshield clears too while you go and have a cup of tea/coffee in the Clubhouse.
Brushing light snow off an airframe is not too bad but as mentioned earlier beware that any water left on the airframe may re-freeze when you begin your flight. Dont assume snow will be blown off on the takeoff run, the wind chill factor makes it freeze onto the metal. If you use deicing fluid only Aircraft de-icing fluid will work, (Car de-icers just re-freeeze after a few mins). Scraping ice off with plastic scrapers will probably damage the finish and the aircraft owner wont thank you for it.
When you finally get airborne, the low winter sun can cause visiblity problems plus dont get caught out on a cloudless afternoon when the sun is low on the horizon, its actually already nearly dark on the ground ! (hint you can see the streetlights/ car headlights coming on!). If you dont have a night rating and your home airfield does not have runway lights plan your flight to end 30mins or more before sunset.
If you fly from a grass strip beware that wet grass/mud is more slipery than ice and the Aircraft can be hard to control on the ground when taking off and landing particularly in a crosswind !
Watch the Temperature/Dewpoint difference on the TAFs /Metars if its close you could get fog/mist developing in the late afternoon.
Winter flying can be safe and enjoyable but like all things in aviation the key is in the preparation.
