Also known as a full survey, this is the fullest and most comprehensive of the options open to the property buyer. It involves an extensive investigation of the property and a thorough examination of all the major aspects and minor details that are visible. There is some flexibility as you can request the surveyor to concentrate on specific features of the property. It is most suitable for larger, older homes with more potential for problems and those more than 75 years old, property over three stories in height, buildings of unusual construction (such as thatched, timber etc.), or if you plan to extend, convert or renovate the property. A full structural survey can cost you anything from £400 to £1000.
