I don’t think you’d ever get them to change the agreement in this way! They will never take increased costs on the chin or actually have a “fixed price” – I believe the only fixed price you will ever get is if you buy a house and land package on a standard agreement for sale and purchase and then literally don’t change ANYTHING! I have never known anyone on a build contract to ever pay the price they were first quoted! If anyone has then they have been very very lucky – its not the norm. I have in the past run contracts past lawyers who have tried to amend clauses, only to be told by the builder “no, like it or lump it” – especially in a busy market, they don’t have to please the customer in this way. Its no good for the consumer, but that’s the way it is unfortunately.
