Do ask for quotation for legal fee for both S&P and loan documentation from different law firm. The stamp duty and valuation fee is fixed. There is calculation for legal fee but usually they will mark up. Even bankruptcy search can be charged double.

I've got all legal fee plus stamp duty&valuation for 10k all in for a property price 440k. If i did not ask for discounts, I will be charge 16k. Find law firm that have good clerk, the clerk that incharge of my loan is very fast and helpful.
