Structural Survey Services
Independent structural surveys for residential and commercial properties across the UK, giving you a clear understanding of a building's true condition and safety.
What Is a Structural Survey?
A structural survey is a detailed engineering inspection of a building's structure, including the foundations, load-bearing walls, beams, floors and roof, carried out by a qualified structural engineer to assess safety, identify defects and recommend repairs. At LENIO Group, we provide independent structural surveys for residential and commercial properties across the UK, giving you a clear understanding of a building's true condition and safety.
Whether you are buying a property, have noticed cracks in the walls, or are planning renovations, our structural surveys provide accurate technical insight backed by professional engineering knowledge. Unlike a general property survey, ours focus specifically on structural safety, stability and engineering performance, and our reports explain clearly what the issue is, why it is happening, whether it is serious, and what actions or repairs are required.
What We Check in a Structural Survey
Our structural engineers assess the key elements that determine the safety and stability of a building. We examine the foundations for movement and settlement, which can occur due to soil conditions, water damage or poor construction, and we carefully assess cracks in internal and external walls and ceilings to determine whether they are cosmetic, thermal or structurally significant.
We also check the stability of load-bearing walls, the condition of the roof structure including rafters, trusses and connections, and the performance of beams and columns that transfer loads through the building. In addition, we inspect floors for deflection or uneven movement and look for wider signs of structural distress, such as severe cracking patterns, bulging walls or separation between structural elements, helping to identify problems early before they become serious.
Foundations & Settlement
Checking for movement caused by soil conditions, water damage or poor construction.
Cracks in Walls & Ceilings
Assessing whether cracks are cosmetic, thermal or structurally significant.
Load-Bearing Walls
Confirming the stability of the walls that carry the building's loads.
Roof Structure
Inspecting rafters, trusses and connections for condition and support.
Beams & Columns
Reviewing how key elements transfer loads through the building.
Floors & Distress Signs
Checking floors for deflection and looking for wider signs of structural distress.
Why Structural Surveys Are Important
Many serious structural issues are not visible during a standard viewing or inspection, so problems such as cracks, movement or hidden defects can go unnoticed and later lead to expensive repairs or safety risks. A structural survey helps property owners and buyers make informed, confident decisions by providing a clear and detailed evaluation of a building's condition.
It allows you to understand the true structural condition of a property, avoid unexpected repair costs, make safe and informed purchase decisions, plan renovations or extensions with confidence, and detect hidden defects early before they become more serious.
What You Receive
After the survey, you receive a detailed structural report that provides a full assessment of the building's structural condition. The report describes any defects found, explaining the type, location and visible symptoms, and sets out an engineering analysis of the causes, such as ground movement, structural overloading, poor construction or material deterioration.
Each issue is assessed and categorised by severity, so you understand clearly whether it is minor, moderate or serious and how it may affect the building. The report then provides practical repair or strengthening recommendations, written in clear, easy-to-understand language while maintaining professional engineering accuracy.

Our Structural Survey Process
We begin with an initial consultation to understand your concerns and determine the type of survey required, whether you are buying a property, noticing cracks, planning an extension or experiencing movement. We then provide a tailored quotation based on the property size, location and complexity, and arrange a convenient survey date once it is approved.
One of our qualified structural engineers then carries out a detailed on-site inspection, assessing the foundations, load-bearing walls, beams, columns, floors, roof structure and any visible cracks or movement. After the visit, we review the findings, determine the root causes and severity of any issues, and prepare a clear engineering report. If repairs, renovations or strengthening work are required, we can provide further engineering guidance to help you move forward with confidence.
Structural Survey or Building Survey?
A building or home survey is a general property inspection carried out by a surveyor to assess overall condition, but it does not provide detailed engineering analysis. A structural survey is more technical and is carried out by a structural engineer, focusing specifically on the structural safety and performance of the building and providing engineering-based solutions for any defects found. For properties with cracking, movement or suspected structural problems, a structural survey is usually the more appropriate choice.
Frequently Asked Questions
A structural survey is a detailed engineering inspection of a building carried out by a qualified structural engineer. It focuses on the strength, stability and overall condition of the structure, including the foundations, walls, beams, floors and roof. Unlike a basic property inspection, a structural survey examines how the building is performing structurally and identifies any defects, movement or potential risks. The findings are explained in a clear report with practical recommendations.
In many cases, a structural survey is highly recommended before purchasing a property, particularly for older buildings or those showing visible cracks or movement. It helps you understand whether the property has hidden structural problems that could lead to costly repairs in the future. With this information, you can proceed with confidence, plan any necessary works, or renegotiate the price if issues are found.
During a structural survey, the engineer examines all of the key load-bearing and structural elements of the building, including the foundations, external and internal walls, roof structure, beams, columns and floors. They also look for warning signs such as cracking patterns, uneven floors, settlement, bowing walls and water-related damage. The engineer then determines whether any issues found are cosmetic, minor or structurally significant, and explains what this means for the property.
The on-site inspection for a structural survey usually takes a few hours, depending on the size and condition of the property. After the inspection, the engineer prepares a detailed report, which typically follows within a few working days. The report sets out the findings, explains the likely causes, and provides clear, professional recommendations so you fully understand the condition of the structure.
A home survey is a general property inspection carried out by a surveyor to assess overall condition, but it does not go into detailed engineering analysis. A structural survey is more technical and is carried out by a structural engineer, focusing specifically on structural safety and performance. It provides a deeper assessment of any defects and sets out engineering-based solutions. For properties with cracking or movement, a structural survey is usually the more suitable option.
Structural surveys are carried out by qualified structural engineers with professional experience in building analysis, structural design and construction behaviour. At LENIO Group, our engineers are trained to assess complex structural issues and provide accurate, reliable and practical recommendations based on UK engineering standards. This ensures you receive trustworthy advice backed by genuine engineering expertise.
