I've just started trying to get quotes for our renovation and one of the builders has told me that they charge for the quote. The size of the fee depends on the scale of the job and is refundable if they take on the job. Is this usual now? Good or bad? They are highly recommended and have a waiting list of about 8 months so I'm wondering whether to suck it up or keep banging my head against a brick wall attempting to get other builders to quote.
