A structural survey is an in-depth, targeted inspection of a building's load-bearing elements and overall integrity. It is typically conducted by a chartered structural engineer to diagnose specific defects (like cracks, subsidence, or bowing walls) or to assess a property before major renovations.
The purpose of a structural survey is to identify any defects or potential problems with the structure of the building that may affect its stability, safety, or value. This can include things like cracks in walls or foundations, problems with the roof or chimney, and issues with damp or rot.
A red flag in a survey refers to severe problems found during the inspection that must be repaired as soon as possible. These concerns typically relate to structural decay and can have a significant negative impact on the property value.
The surveyor will take around 1-4 hours to complete the physical survey of your home, depending on the size and type of property. Full structural surveys, which are more in-depth, can take anywhere between 3-8 hours to complete.
Structural red flags include wide or progressive cracks in walls, sloping floors, bowing walls, signs of subsidence, or a visibly sagging roof. These issues can indicate movement in the property's foundations and often require evaluation by a structural engineer to determine the seriousness and cost of repair.
Factors that decrease property value the most fall into three main categories: location issues, structural damage, and poor neighborhood conditions. These factors can collectively slash a property’s value by 5% to 30% or more.
Look for defects
Surveyors look for visible signs of wear, tear and damage to a property that may affect the sale price or enable buyers to negotiate a better deal. A survey also involves checks for hidden problems like damp, mould, structural movement, roof defects and utility problems.
A full structural survey, also known as a RICS Level 3 Building Survey, costs an average of £656 in the UK, typically ranging from £574 - £894. The final price will depend on your property's value, complexity, and location, as well as your chosen RICS surveyor's availability.
The surveyor will carry out a visual inspection of these installations. He will check things like light switches, plug sockets, extraction fans, run taps and flush toilets.

Key Takeaways: Property Red Flags at a Glance
Structural issues like foundation cracks or systemic damp are often “run away” signs. Legal “DIY” (unpermitted extensions or conversions) can lead to massive fines or insurance voids. Environmental hazards like Japanese Knotweed or flood risks shouldn't be ignored.
Property survey and utility flags follow the American Public Works Association (APWA) national uniform color code. These colors identify boundaries, temporary markings, and underground utilities.
There are many issues that can be red flags on a home inspection, but the most serious include structural or foundation problems, major water damage or an active leak, or problematic electrical wiring. All of these can be very costly to repair and can create safety or health hazards.
Do I need a survey when buying a house? Yes, we advise that you need a survey when buying a house. It identifies potential issues, such as structural problems, which could impact the property's value and your decision to purchase. You might use the unbiased information from the survey to renegotiate the price.
5 common survey question mistakes that'll ruin your data
Good survey questions are specific, unbiased, and tailored to what you want to learn. Here are 5 essential, universally effective questions across different categories:
Of course, everyone makes mistakes, and surveyors are no exception. It could be that a survey performed 100 years ago was inaccurate and is now calling your property lines into question. Even modern surveying equipment is subject to operator error, so the owners of newer homes can also run afoul of a boundary dispute.
Below we outline what to expect during the visit and how you can prepare effectively.
A drain survey is not included in a standard house survey. Property surveyors do not have the tools and experience to provide a thorough drain inspection.
Whilst you may have already gone back and forth with the vendor to reach a mutually agreed price prior to your survey, as the buyer you are completely within your rights to renegotiate if the survey reveals unexpected issues which impact the property's value.
For most modern properties of standard construction, you should get a level 2 survey. If you are purchasing an older or unusual property or one which has been extended or developed, you should get a level 3 survey.
Whilst a 20 year old home isn't really all that old, it is worth having, at least, a homebuyer's survey conducted to check for issues that may not be immediately visible to an untrained eye. The last thing you want is to purchase your dream home, only to find it has some less-than-ideal qualities further down the road.
Common red flags on a house survey include damp, subsidence, electrical problems, asbestos and insulation issues. Some are relatively minor and easy to fix, while others may affect the property's value or mortgageability.
Disadvantages of surveys
Opinion surveys are indispensable tools in market research. To obtain reliable results, you need to avoid 4 types of statistical error. In this article, I explain each error in detail: coverage, sampling, non-response, and measurement errors.
