A RICS Level 2 survey (Home Survey Level 2) is a visual inspection suited to conventional homes built after 1900 and in reasonable condition. A Level 3 survey (Building Survey) is a detailed, analytical inspection suited to older, altered or non-standard properties. It also explains why defects have happened and how to put them right.
In short: a Level 2 tells you the condition of a property. A Level 3 tells you the condition, the cause, the consequence and the cure.

Buying a home is one of the biggest financial decisions most of us will ever make. A professional building survey gives you a clear picture of what you are actually buying, including the defects, structural issues and maintenance concerns that are almost impossible to spot during a viewing.
But which survey do you need? At Cornerstone Surveyors, we carry out RICS Level 2 and Level 3 residential surveys every day, and it’s the question we are asked most often. We are an independent, residential-only practice, so our advice is based on one thing: what is right for you and your property. This guide gives you a straight answer.
A building survey is a professional inspection of a property carried out by a qualified RICS surveyor. It assesses the condition of the home, identifies defects and flags anything that could affect its value or cost you money after you’ve moved in.
In the UK, RICS (the Royal Institution of Chartered Surveyors) sets the standards for residential survey types. The two most commonly chosen for home purchases are the Level 2 and the Level 3. Which one is right depends on the age of the property, its condition and what you plan to do with it.
Skipping a survey altogether carries real risk. According to RICS, buyers who purchase without a survey face an average of £5,750 in unexpected repair costs after moving in, and 17% spend more than £12,000 making their new home habitable.
A Level 2 survey, also known as a Home Survey Level 2 (and previously as a HomeBuyer Report), is the most popular choice for mainstream residential purchases. It is designed for conventional properties in reasonable condition, and gives you a practical, clear overview without the deeper structural analysis of a Level 3.
Our RICS Level 2 survey report uses a traffic light condition rating system. That makes it easy to see at a glance what needs urgent attention, what is a minor concern and what is in satisfactory condition.
A Level 2 is the right choice if your property was built after 1900, uses standard construction materials and methods, and appears to be in reasonable condition. There should be no obvious signs of major alteration or neglect. For most typical houses and flats, it is a cost-effective way to get genuine reassurance without paying for a level of detail you don’t need.
Typical cost: from £700, depending on the size and location of the property.
A Level 3 survey, also known as a Building Survey, Full Building Survey or Structural Survey, is the most comprehensive inspection available for a residential property. It goes well beyond a visual assessment. Your surveyor examines the structure, construction and materials in depth.
Unlike a Level 2, our RICS Level 3 building survey explains not just what defects exist, but why they have occurred and what should be done about them. You will typically receive repair recommendations, maintenance priorities and, where possible, cost guidance for remedial work.
A Level 3 is the right choice if your property was built before 1900, or if it has been significantly extended or altered. It is also the safer option for homes built from non-standard or unusual materials, and for any property where you have noticed damp, cracking, sloping floors or signs of movement during a viewing.
If you are planning major renovation or structural work after you buy, a Level 3 gives you the detail you need to plan and budget with confidence. It is the survey we most often recommend for period, listed and older homes, which make up much of the housing stock across Gloucestershire, the Cotswolds and the wider South West.
Typical cost: every Level 3 is quoted individually, because every property is different. In our area, they typically start from £1,000. Size, age, construction type, location and complexity all affect the price, and we explain each of them in our guide to what affects the cost of a Level 3 survey.
Both surveys are carried out by qualified RICS surveyors, and both will identify defects and flag concerns. The difference lies in the depth of the investigation and the detail of what you get back.
A Level 2 is a visual assessment. Your surveyor records what can be seen, such as surface defects, signs of damp and evidence of movement, and rates each element using the traffic light system. It is clear and practical, and well suited to properties where the risk of hidden or complex problems is low.
A Level 3 is a far more analytical exercise. Your surveyor doesn’t just record what is visible. They investigate why a defect has occurred, assess what it means for you and advise on how to deal with it. They will also go further physically, entering roof spaces, lifting accessible inspection hatches and examining construction techniques in detail. The report is longer and richer, and it is genuinely useful when you are dealing with an older, altered or structurally complex home.

Work through these four questions to find the right fit.
Built before 1900? A Level 3 is recommended. Built after 1900? A Level 2 is likely to be enough, as long as the answers below don’t point the other way.
No? A Level 2 is likely to be suitable. Yes? A Level 3 gives you the deeper inspection you need.
None visible? A Level 2 may be enough. Spotted something? A Level 3 will give you a clearer picture of the cause and extent.
No? A Level 2 is fine. Yes? A Level 3 gives you the detail to plan and budget properly.
If you are still unsure, get in touch before you book. We can advise on the right survey level based on the age, construction and condition of the property.
A survey that flags issues is not necessarily a reason to walk away. It gives you options. Depending on what is found, you may be able to renegotiate the purchase price to reflect the cost of repairs, ask the seller to deal with specific defects before exchange, or commission a specialist report (from a structural engineer or damp specialist, for example) to understand the scope and cost.
Your Cornerstone surveyor will always talk you through the findings, so you can understand what is serious, what is routine and what simply needs monitoring. If you’d like to know what surveyors look for, our library of common building defects and issues explains them in plain English. The report is the start of a conversation, not the end of one.
We are an independent, residential-only firm, and everything we do is built around helping homebuyers make confident decisions. This is how it works:
A Level 2 is a visual inspection that reports on the condition of a conventional property, while a Level 3 is an in-depth inspection that also explains the causes of defects and how to repair them. A Level 3 is best suited to older, altered or non-standard homes.
Not necessarily. A Level 3 is more detailed, but for a conventional property built after 1900 and in reasonable condition, that extra detail often isn’t needed. The best survey is the one that matches the risk profile of your property, not always the most expensive one.
Yes. The RICS Home Survey Level 2 is the current name for what was formerly known as a HomeBuyer Report. You will still see both terms used, but they refer to the same type of survey. If you’d like a deeper comparison, read our guide to the difference between a HomeBuyer Report and a Building Survey.
In most cases, yes. Period and listed homes often use traditional materials and construction methods that need specialist interpretation, and a Level 3 gives you that depth. See why this matters in our guide to a Level 3 survey for a Victorian house, or read about listed building survey costs if you are weighing up the price.
It depends on the condition and construction. A 1970s home was built after 1900, so a Level 2 survey is often suitable if it is well maintained, unaltered and built with standard materials. If it has been extended, shows signs of defects or uses non-traditional construction, such as concrete or timber frame, a Level 3 is the safer choice.
A Level 2 typically takes two to four hours on site, depending on the size of the property. A Level 3 generally takes longer, often half a day or more, because the inspection goes into greater depth.
Both surveys are non-invasive, so surveyors can’t open up walls or lift fixed floors. However, an experienced surveyor will recognise the signs that suggest hidden problems and will recommend further specialist investigation where needed. This is why choosing a qualified, experienced RICS surveyor matters.
No. A Level 3 focuses on the condition of the property rather than its market value. If you need a valuation as well, we can usually add one to your survey, or arrange a separate private valuation.
Choosing the right survey is one of the most important steps in any property purchase. Whether you need a Level 2 Home Survey for a more modern home or a Level 3 Building Survey for an older or more complex property, Cornerstone Surveyors provides RICS-accredited, independent inspections across Gloucestershire, the Cotswolds, Bristol and Somerset.
