Survey Guide • Buying a Home • RICS Surveys
One of the most common questions buyers face is which survey to choose. Level 2 or Level 3 — the names are not very helpful on their own, and the difference matters more than most people realise.
This guide explains exactly what each survey covers, how they differ in depth, and how to decide which is right for the property you are buying.
Quick answer: A Level 2 survey suits most modern, well-maintained properties in reasonable condition. A Level 3 survey is the better choice for older properties, those with known issues, or anything you suspect may need significant work. When in doubt, go Level 3.

What is a Level 2 survey?
A Level 2 survey — also called a RICS Home Survey Level 2 or Homebuyer Report — is a visual inspection of a property’s condition. It is the most commonly chosen survey for straightforward residential purchases.
The surveyor inspects the property throughout and assesses visible elements: the roof, walls, floors, windows, ceilings, drainage, and services. They are not required to lift floorboards, move furniture, or investigate behind surfaces. The inspection is visual and non-destructive.
The report grades each element using a simple traffic light system:
- Condition Rating 1 (green): No repair needed at the time of the inspection.
- Condition Rating 2 (amber): Defects that need attention but are not considered serious or urgent.
- Condition Rating 3 (red): Defects that are serious and/or need to be repaired, replaced, or investigated urgently.
A Level 2 survey typically includes a valuation section (if requested), a summary of risks, and guidance on legal issues. It gives buyers a clear overview of condition without going into the depth of a full building survey.
You can find out more on our RICS Level 2 Survey page.
What is a Level 3 survey?
A Level 3 survey — also called a RICS Home Survey Level 3 or Building Survey — is the most thorough residential survey available. It provides a detailed assessment of the property’s construction, materials, and condition.
The surveyor examines the property in significantly more depth than a Level 2. They assess the roof structure (where accessible), the building fabric, damp, drainage, structural elements, and any significant defects. Where they are unable to inspect a particular area, they will note this as a limitation and may recommend further investigation.
The Level 3 report is longer and more detailed. It describes what the surveyor found, what it may mean in practical terms, and what action may be needed. It does not use the traffic light condition ratings — instead, it provides a full written account of findings and their significance.
A Level 3 is particularly suited to:
- Older or period properties (Victorian, Edwardian, pre-war)
- Properties with unusual construction (timber frame, stone, conversion)
- Properties that have been altered or extended
- Properties where the buyer wants maximum detail before committing
See our RICS Level 3 Building Survey page for a full description of what is included.
Key differences side by side
| Feature | Level 2 Survey | Level 3 Survey |
|---|---|---|
| Inspection depth | Visual and non-intrusive | Thorough; greater detail on structure and materials |
| Report format | Traffic light condition ratings | Detailed written descriptions of all findings |
| Defect detail | Identifies defects; limited commentary on cause | Explains defects, likely causes, and repair implications |
| Property type | Modern or well-maintained homes | Older, larger, or complex properties |
| Valuation | Optional add-on | Not typically included (separate valuation available) |
| Report length | Shorter, structured | Longer, narrative-style |
| Typical use | Standard residential purchases | High-value, older, or complex properties |
Which survey suits which type of property?
The right survey depends on the property itself, not just the buyer’s preference. A newer, standard-build property in good visible condition is generally well-served by a Level 2. An older, altered, or unusual property often requires the depth of a Level 3 to give the buyer the information they need.
Level 2 tends to suit:
- Properties built after 1950 in conventional construction
- Homes that appear well-maintained and structurally straightforward
- Buyers who want a clear condition overview rather than an in-depth analysis
- Properties where the estate agent or vendor has provided recent maintenance records
Level 3 tends to suit:
- Properties built before 1920 or with non-standard construction
- Conversions — barns, mills, commercial-to-residential, flats in older buildings
- Any property with visible signs of movement, damp, or significant alteration
- Large or high-value homes where the stakes of missing a defect are higher
- Properties where the buyer is planning major renovation or extension work
Surveyor’s note: If you are unsure which level to choose, a RICS-qualified surveyor can advise based on the type, age, and condition of the property before you book. It is better to ask early than to discover limitations after the report is received.
Is a Level 3 survey worth it?
For the right property, a Level 3 survey typically pays for itself many times over. A detailed report can reveal defects that are not visible on a standard inspection — issues with the roof structure, hidden damp, problematic alterations, or structural movement that would otherwise only emerge after purchase.
The cost of a Level 3 survey may be higher than a Level 2, but the information it provides can support price renegotiation, help you budget for repairs, or in some cases give you good reason to walk away from a purchase before exchange.
Buyers sometimes hesitate because they feel a Level 3 is excessive for a property that looks fine. In our experience, older properties rarely look exactly as they are. Hidden problems in Victorian terraces, Edwardian semis, and converted properties are common — and often not visible without a thorough inspection.
If the property is important enough to spend hundreds of thousands of pounds on, a Level 3 survey is a proportionate response.
Do I need a Level 3 survey?
You are not required by law to get any survey. The decision is yours. A mortgage lender’s valuation — which some buyers confuse with a survey — is not a survey at all. It assesses the property’s value for lending purposes, not its condition. It will not flag the defects a buyer survey would find.
If you are buying without a mortgage, there is no third-party check on condition at all. Getting a Level 2 or Level 3 survey is the only way to understand what you are buying before you complete.
In practical terms, you may want to consider a Level 3 if any of the following apply:
- The property is more than 60–70 years old
- You can see cracks, damp patches, or evidence of past repairs
- The property has been extended, converted, or significantly altered
- You are buying a flat in an older block and want to understand the building’s overall condition
- You simply want the most complete picture possible before one of the largest purchases of your life
If none of those apply and the property is a modern home in good order, a Level 2 may be sufficient. But if there is any doubt, the additional depth of a Level 3 is usually the right call.

Frequently asked questions
Can I upgrade from a Level 2 to a Level 3 after the inspection?
Not usually. The two surveys involve different inspection approaches and produce different reports. If you want a Level 3, it is worth booking that from the start rather than commissioning a Level 2 and later wishing you had more detail.
Does a Level 3 survey include a valuation?
A standard Level 3 building survey does not typically include a formal RICS valuation. If you need a valuation alongside a detailed survey, it is worth discussing this when you book. LM Surveyors also offers separate private valuation services.
Is a Level 2 survey the same as a Homebuyer Report?
The RICS Homebuyer Report was the predecessor to the current Level 2 format. They are broadly similar in scope and purpose. The Level 2 is the current RICS standard for this type of inspection.
What if the surveyor finds something serious in a Level 2?
If a Level 2 survey returns a Condition Rating 3 (red) for an element, the report will typically recommend further investigation by a specialist. You can then decide whether to obtain additional reports, renegotiate the price, or proceed with the purchase factoring in likely repair costs. A specific defect report may be useful in those circumstances.
How long does each survey take?
Survey duration varies by property size and complexity. A Level 2 inspection on a standard two or three bedroom home may typically take two to three hours on site. A Level 3 on a larger or older property is often longer. Your surveyor will confirm an expected timeframe when you book.
