A structural survey, also known as a Full Building Survey or Level 3 Survey, is the most thorough type of property inspection. It provides an in-depth analysis of the property's construction, materials and condition, including areas that a homebuyer report would not cover.
The surveyor will examine the property in far greater detail, looking at the building's structure, identifying defects and their likely causes, and advising on necessary repairs with estimated costs. The resulting report is comprehensive and can run to many pages.
A structural survey is recommended for older properties (typically pre-1900), unusual constructions (such as timber-framed or thatched buildings), properties that have been significantly altered, or any property where you suspect there may be structural issues. It is the most expensive type of survey, typically costing between £800 and £2,500 depending on the property, but it provides the greatest peace of mind and the most detailed information for decision-making.
You are buying a Victorian terraced house built in 1890. Your mortgage broker recommends a structural survey given the age of the property. The surveyor discovers that the rear extension has subsidence and estimates repairs at £15,000, which you negotiate off the purchase price.
