Beyond the Bricks: Why a Building Survey Could Be Your Most Important Home-Buying Decision

Buying a home is likely to be one of the biggest financial commitments you will make. Whether you are purchasing a Victorian terrace, a modern apartment or a rural cottage, it can be difficult to know exactly what you are buying from a viewing alone.

Fresh paint and a well-presented interior can make a strong first impression, but they tell you very little about the condition of the roof, walls, drainage, structure and other important parts of the property.

This is where a building survey can prove invaluable. A professional survey can help you understand the condition of a property before you commit to the purchase, identify potential problems and make a more informed decision about what the property is really worth to you.

What Is a Building Survey?

A building survey is a professional inspection of a property carried out by a building surveyor. Its purpose is to assess the condition of the building and highlight defects, areas of concern and potential future maintenance requirements.

Depending on the type and scope of the survey, the surveyor may assess elements including the roof, external walls, windows and doors, floors, ceilings, internal walls, visible structural elements, drainage and other accessible areas of the property.

The findings are then presented in a written report, giving you a clearer picture of the building you are considering purchasing.

Importantly, a building survey is different from a mortgage valuation. A valuation is primarily undertaken for the lender to establish whether the property provides suitable security for the mortgage. A survey is undertaken for you, the buyer, and focuses on helping you understand the condition of the property.

From HomeBuyer Reports to Level 1, 2 and 3 Surveys – What Has Changed?

The terminology used for residential property surveys has changed over the years, which can understandably cause some confusion for home buyers.

Historically, buyers may have been familiar with terms such as the HomeBuyer Report, HomeBuyer Survey and Valuation, Condition Report and Building Survey. You may still hear these terms used today, particularly “HomeBuyer Report”, even though the current RICS framework uses a different approach.

The Royal Institution of Chartered Surveyors (RICS) introduced the RICS Home Survey Standard to provide greater consistency in residential surveying. Under the current standard, surveys are broadly distinguished by the level of service and detail provided: Level 1, Level 2 and Level 3.

A Level 1 survey is the most concise of the three levels. It provides an overview of the property's condition, identifying significant visible defects and risks but generally without providing detailed advice on repairs. It is typically most appropriate for conventional properties in apparently reasonable condition where a detailed assessment is not required.

A Level 2 survey provides a more detailed inspection and report. This is broadly the level of service many buyers previously associated with a HomeBuyer Report or HomeBuyer Survey. It is commonly suited to conventional houses, flats and bungalows of standard construction and aims to identify defects that could materially affect the property.

A Level 3 survey provides the most comprehensive level of inspection and reporting under the RICS Home Survey Standard. This is the level most closely associated with what has traditionally been called a Building Survey or, historically, a Full Structural Survey. It is particularly appropriate for older, larger, unusual, extensively altered or visibly deteriorated properties, as well as properties where significant renovation or repair works are anticipated.

We typically recommend a Level 3 survey as, in our experience, buyers can be disappointed with the level of detail provided by Level 1 or Level 2 surveys when they want to understand more than simply what defects are present. A Level 3 survey allows for greater detail around the likely root cause of defects, their significance and the appropriate repair or remediation, giving buyers a more complete understanding of the property before committing to their purchase.

Why Have a Building Survey?

Buy With Greater Confidence

A viewing can only tell you so much about a property. A building survey considers the construction and condition of the building from a professional perspective, helping to identify defects and areas of concern that may not be immediately apparent. Having this information before you commit can provide greater confidence in your purchase and reduce the risk of unwelcome surprises after you move in.

Understand What You Are Really Buying

No property is perfect, and identifying defects does not necessarily mean you should walk away. A building survey helps you understand the significance and likely cause of issues identified, distinguishing between routine maintenance and defects that may require more substantial investigation or repair. This gives you a clearer picture of the property's overall condition and what you are taking on as its new owner.

Avoid Unexpected Costs

Roof repairs, structural works, damp-related issues and other significant defects can be expensive to address. While a survey cannot identify every concealed problem or predict future defects, it can highlight visible issues and potential areas of expenditure before you purchase, allowing you to factor likely repairs and maintenance into your budget.

Strengthen Your Position When Negotiating

Where significant defects are identified, a building survey can provide a useful basis for further investigation, obtaining repair quotations and, where appropriate, renegotiating with the seller. A survey does not automatically justify a reduction in the purchase price, but it gives you professional information on which to base discussions rather than relying on assumptions.

Identify Where Further Investigation Is Needed

Some defects require specialist investigation before their cause or extent can be fully established. A building survey can identify when further advice may be appropriate, such as from a structural engineer, drainage specialist, electrician or other suitably qualified professional, allowing you to investigate potentially significant issues before committing to the purchase.

Plan for Future Maintenance

A survey is not only about identifying immediate problems; it can also help you understand how the property should be maintained in the years ahead. This can be particularly important with older buildings, where traditional materials and construction methods may require a different approach to modern properties, helping you plan and budget for future maintenance.

Is a Building Survey Worth It?

In short, yes. When compared with the potential cost of unexpected repairs or remediation after purchasing a property, a building survey represents a relatively small investment. By identifying defects before you commit, it gives you the opportunity to understand potential costs, negotiate where appropriate and make a more informed decision, making it a valuable tool when buying a home.
