Pricing is based on the sale value of the property. This is an unfair pricing strategy as it's not based on the amount of work the surveyor will be doing. I had a chat with one of the surveyors (who happened to be charging a lot more than all the others) and he gave me some nonsense about it being difficult to price if this strategy wasn't used. There are many fairer ways to price. It could be based on square footage, age of the property, number of bedrooms perhaps. If the price of property keeps increasing, so does the surveyor's fee yet the amount of work involved stays the same. Absolute extortion!
