Myself and Mrs Jim are getting some builders in to do some minor DIY involving moving a loft hatch, and some general boxing in in the house. We've had three quotes, one we've discounted due to not being happy with the builder. The other two, one is quoting £240 plus materials (plus VAT?) for some vaguely defined quote, while the last gave the most detailed quote at £550 plus VAT including materials. We went back to the last, who was our prefered choice anyway to get some clarity on how he reached the figure - he sent an email back saying they charged competitive prices, but then four hours later we got another email saying he'd do it for £430 plus VAT (£516). This is a fairly hefty price reduction, which we're not sure whether we're comfortable with or not. If the guy can knock 20% off the price without being prompted, then was he ripping us off with the original price, or is he making savings elsewhere (e.g. using the materials spare from another job?). Any comments would be appreciated - the guy gets good reviews, but we're just uncomfortable at such a large reduction being applied without any negotiation at all - it doesnt feel quite right!
