Habitation check

Just had my third habitation check done, last year it was £170. Nearly fell off my chair on being told it was £299 when I collected it. I wasn't informed of this when dropping it off. This price is way over the top for the amount of work done, & its only a six metre van. Plus the gas taps, awning light & fridge were left on. I was warned that the gas bottles were unsafe due to only having one securing strap, this is how the van was delivered from Baileys & it passed your pre delivery check plus two subsequent hab checks, so why is it now a problem? I have always defended Lowdhams in the past but now I feel aggrieved and am unlikely to be a customer again. So for you its short term gain, long term loss.
