The 3 year old van with tank fitted cost me £10.5k originally.
Poles must have cost me another £3k over the years (I include one pole that was £1.7k.)
A trolley, backpacks, reels, a non-standard size holding tank (so it could fit through the door), membranes, resin, water, unit rental etc., I dread to come up with a number really.
And don't get me started on van repairs and vehicle hire.
Ouch!
Whichever way I slice it though, apart from the first year when I converted to WFP, the profit has always been more than trad bevcause the higher turnover far outstrips the higher expenses.
