It is absolutely worth getting a survey when buying a house! A surveyor will inspect the property thoroughly and inspect on any defects they find, potentially saving you hassle and cost down the line. They can also advise on issues you may wish to get the vendor to address before you buy, or give you the information you need to renegotiate the price to reflect any work that needs doing. You should always make sure your surveyor is Regulated by RICS, the professional body for Chartered Surveyors.
