Homebuyer Report vs Building Survey: Which Do You Really Need?

When you are buying a property, a survey can provide peace of mind, but with a few options on the table it is easy to feel unsure which one is right for you. The two most common choices are the homebuyer report and the building survey report. Both are carried out by RICS surveyors and both set out the problems you may face down the line. Where they differ is in the depth of the inspection and the type of property they suit.

This CJ Bloor guide covers the differences between the two, the situations each works best in, and roughly what a building survey report cost looks like, so you can make the right decision for your purchase.

What is a Homebuyer Report?

A Homebuyer Report, also known as a Level 2 RICS Survey, is a mid-level survey. It is designed for homes that are in a reasonable condition and of a conventional build, typically post-1930s and without major alterations.

It provides a clear picture of the property's overall condition, flagging any visible issues that could affect its value or need attention after you move in.

Read more in our detailed Homebuyer Report guide.

What's included in a Homebuyer Report?

• Inspection of the property's interior and exterior
• Assessment of key areas like the roof, walls, windows, and insulation
• Checks for signs of damp, subsidence, or structural movement
• A traffic light rating system to make findings easy to understand
• Optional market valuation and insurance reinstatement figure

This type of report doesn't delve into concealed or inaccessible areas, so it's suited to homes where no obvious problems are expected. The traffic light ratings follow the RICS condition rating system, where 1 is good and 3 is urgent.

Typical inspection time: 1 to 3 hours on site.

What is a Building Survey?

A Building Survey, or Level 3 RICS Survey, is the most comprehensive survey you can get. It is suited to older, larger, or significantly altered properties, as well as buildings that clearly need repair or renovation.

Unlike a Homebuyer Report, a Building Survey provides in-depth insight into the structure and condition of the property. It is particularly useful if you are planning major work, as it gives you a solid understanding of what you are working with.

This is the survey many people mean when they ask about a "full structural" survey. The term is dated, but the homebuyers survey or full structural question is really the same as homebuyers survey vs building survey: the Level 3 building survey report is the modern equivalent.

What's included in a Building Survey?

• Thorough inspection of the property's structure and fabric
• Detailed analysis of defects, including potential hidden issues
• Advice on necessary repairs and ongoing maintenance
• Photographs of defects for clarity
• Optional market valuation and insurance reinstatement figure

Typical inspection time: 2 to 6 hours on site.

Homebuyer Report vs Building Survey: Key differences

Here is a quick side-by-side to help you compare the two:

As a general rule: if the property is newer and hasn't been extensively modified, a Homebuyer Report may be all you need. If it is older, larger, or looks like it needs work, opt for a Building Survey.

The home buyers report vs building survey decision, then, is driven by the property rather than the price. A cheaper survey on the wrong property is a false economy if it misses the problems you needed it to find.

Building survey report cost

A building survey report cost is higher than a homebuyer report because the inspection takes longer and the reporting is more detailed. Exact fees depend on the size, age and location of the property, so we quote each one individually rather than quote a flat rate.

For a full breakdown of what drives the fee, see our guide to how much a house survey costs. The important point is that the extra spend on a Level 3 building survey report is small next to the repair bills it can uncover on an older or altered home.

How to decide which survey is for you

Your choice of survey should be guided by the age, condition, build type, and complexity of the property. Below we have broken down the most common property types and the survey typically suited to each.

Flats and apartments

If you are purchasing a flat, the type of building it is in can make all the difference.

• For flats in modern, purpose-built blocks that appear to be in good condition, a Homebuyer Report is usually sufficient. It will flag any obvious defects, damp, or issues with things like windows, insulation, and electrics, though the surveyor is limited to the flat and common areas they can access.
• If the flat is part of an older building, particularly converted Victorian or Edwardian houses, and you are purchasing a share of the freehold, then a Building Survey may be a better choice. These conversions often come with unique quirks, shared drainage systems, or older materials that have aged differently. A more detailed inspection helps spot problems hidden behind cosmetic refurbishments, and if you are buying a share of the freehold you will be responsible for a proportionate share of the upkeep of the whole building.

Worth noting: if you are buying a leasehold flat, you won't always get the full picture unless the surveyor can access the roof or communal spaces. If that access is denied or restricted, your report may reflect that.

Victorian or Edwardian homes

Older homes are full of character, but they can also come with hidden issues that aren't obvious during a viewing.

• Victorian and Edwardian properties were built with materials and techniques that don't always stand up well to modern use or weathering. Timber decay, roof sag, outdated electrics, and subtle structural movement are all more likely in properties over 100 years old.
• Even if the property has been maintained or recently refurbished, cosmetic updates can mask deeper problems. A Building Survey looks beyond the surface and provides detailed commentary on everything from damp in solid walls to the condition of original floorboards and roofing.

In short, if the property was built before 1930, a Building Survey is usually the safer bet.

Homes that have been extended or renovated

A modernised kitchen or loft conversion might look great in the photos, but how well were those changes carried out, and did they meet building regulations?

• If you are buying a property that has had extensions, loft conversions, internal knock-throughs, or other structural changes, a Building Survey is generally the better option. It assesses the work that is visible and any signs of poor workmanship or knock-on effects.
• Surveyors can also spot where improvements have been made without adequate support, insulation, or damp proofing, all of which can cost thousands to put right if left unchecked.
• Where structural calculations or planning permissions are missing, the surveyor can advise on next steps or recommend a legal review before proceeding.

New build properties

If you are buying a property that has just been constructed, or is still under warranty, a traditional survey might not be necessary. Instead, what you will usually want is a snagging survey.

• Snagging surveys focus on catching poor workmanship, incomplete finishes, and defects in fittings or construction quality, such as scratched windows, misaligned doors, or issues with underfloor heating and ventilation.
• A snagging inspection is typically carried out before you move in so the developer can correct any problems under the warranty. It ensures you are not footing the bill for someone else's shortcuts.
• If you are buying a new build that is more than a few years old but still under warranty, you might still opt for a Homebuyer Report, especially if the property is showing early signs of wear.

Read more in our guide to the new build snagging survey.

Listed buildings or homes in conservation areas

These properties come with their own set of challenges. From restricted materials to special maintenance rules, any work done on a listed property must meet very specific standards.

• A Building Survey is strongly recommended for listed properties or those in designated conservation areas.
• The surveyor will check for defects and can also comment on historic materials, the potential impact of weathering, and the kind of repairs allowed under conservation guidelines.
• These reports are usually tailored, giving you a clearer understanding of what is realistic for future maintenance or improvements.

Not sure where your property sits?

Sometimes it is not obvious which category your property falls into, especially if you are buying in an area with a mix of old and new homes, or if the seller has undertaken partial renovations.

That is where CJ Bloor's pre-survey consultations come in. If you are unsure whether you need a Level 2 Homebuyer Report or a Level 3 Building Survey, just submit an enquiry selecting the level of service you believe is appropriate. We will review the property details and either provide a quotation based on that level or advise if an alternative level would be more suitable.

Frequently asked questions

What is a building survey report?

A building survey report is the written output of a Level 3 RICS survey. It sets out the condition of the structure and fabric in detail, explains the defects found, and gives advice on repairs and ongoing maintenance. It suits older, larger or altered properties where a fuller inspection is worthwhile.

Homebuyers report or building survey: how do I choose?

CJ Bloor's advice is to let the property decide. A homebuyer report is likely to be enough for a modern, conventional home in reasonable condition. A building survey report is the safer choice for a property built before 1930, one that has been extended or altered, or one that clearly needs work.

Is a homebuyers survey the same as a full structural survey?

No. A homebuyer survey is a Level 2 report with a moderate level of detail. A "full structural" survey is an older name for the Level 3 building survey report, which goes into far more depth. If someone asks about homebuyers survey or full structural, they are really weighing up Level 2 against Level 3.

How much does a building survey report cost?

A building survey report cost is higher than a homebuyer report because the inspection and reporting take longer. The exact fee depends on the size, age and location of the property, so we quote each job individually. See our house survey cost guide for what drives the price.

Does a building survey report include a valuation?

Not as standard. Neither a homebuyer report nor a building survey report includes a valuation by default, but both can have one added on request. If you want reassurance on the price, ask for the valuation option when you request your quote.
