Thanks for the kind words everyone.
Still can't get to the warehouse so I've no idea how bad it is in there but when I saw it yesterday (from the hills behind) there was maybe 2-3 feet of water surrounding it.
So that means that all my Karrimor stuff is flooded, the highlander bags, probably the Gransfors, definitely the kelly kettles, most of my maxpedition gear and god knows what else. That's assuming the racking didn't fall over in which case everything is knacked.
If my server is dry then restarting should be quite quick (pending clean premises and payout), if not the that slows stuff down rather.
Biggest pain at the moment is that I can't contact the insurers! The number on their website goes through to a third party domestic helpline and they haven't a clue how to contact commercial. The brokers are shut and my paperwork is of course in a filing cabinet in the unit.
Nowt I can do until Monday.
