What Type of Survey Do I Need When Buying a House?
Level 1, Level 2, Level 3 — choosing the wrong survey could cost you thousands. Here's how to pick the right one for the property you're buying.
A house survey is one of the most important things you'll pay for when buying a property — and one of the most misunderstood. Many buyers default to the cheapest option, or skip a survey altogether, not realising what they're leaving themselves exposed to.
According to research by Compare My Move, 35% of buyers who commissioned a survey were able to negotiate a lower purchase price as a result, saving an average of £6,390. That figure alone makes the cost of a survey — typically £400–£700 for most buyers — look like one of the better investments in the entire process.
The question isn't really whether to get a survey. It's which one.
The Three Types of RICS Survey
All three survey levels are provided by surveyors registered with the Royal Institution of Chartered Surveyors (RICS). Always verify your surveyor is RICS-registered before commissioning.
There is also a fourth body — the Residential Property Surveyors Association (RPSA) — whose Home Condition Survey is broadly equivalent to a RICS Level 2. Both are valid choices; the key is using a properly accredited surveyor regardless of which body they belong to.
Level 1: When Is It Actually Appropriate?
Rarely. The Level 1 Condition Report is designed for new or near-new properties in excellent condition built from standard materials. It gives a traffic-light overview of visible condition but provides no repair advice and no valuation.
The price difference between a Level 1 and Level 2 is modest — Level 1 starts at around £300, Level 2 from around £400. For that relatively small additional cost, a Level 2 gives you repair advice, deeper inspection, and the option to add a market valuation. According to RICS, Level 1 is aimed at conventional properties in good condition — but even in that scenario, most buyers are better served by a Level 2.
A Level 1 survey does not provide advice on how to manage any defects it identifies. If a problem is flagged, you're on your own in terms of understanding its significance or cost. For most purchases, a Level 2 is a significantly better use of money for a modest price difference.
Level 2: The Right Choice for Most Buyers
The RICS Level 2 Home Survey (formerly called the HomeBuyer Report) is the most commonly chosen survey in the UK, and for good reason. It strikes the right balance between depth and cost for the vast majority of residential purchases.
It covers:
- A detailed inspection of all visible and accessible areas
- Condition ratings with traffic-light system for each element
- Advice on defects that need repair or monitoring
- Identification of issues that may affect the property's value
- Optional market valuation and insurance reinstatement figure
Cost: Typically £400–£1,000 depending on property value, size, and location. HomeOwners Alliance puts the average at £400+ for a standard property.
Time on site: 1–4 hours.
A Level 2 is appropriate for:
- Standard houses, flats, or bungalows built from conventional materials
- Properties built after approximately 1960
- Homes that appear to be in reasonable condition with no obvious red flags
- Properties that have not been significantly altered or extended
Level 3: When You Need the Full Picture
The Level 3 Building Survey (formerly the RICS Building Survey or Full Structural Survey) is the most thorough survey available. It goes beyond what's visible to provide a detailed analysis of structure, construction, and defect causes — along with repair priorities and estimated costs.
The surveyor will inspect roof spaces, look under floorboards where accessible, assess non-standard construction materials, and provide specific guidance on the likely cost and urgency of any remedial work.
Cost: Typically £630–£1,500+, depending on property value and complexity.
Time on site: Up to a full day for complex properties.
If you're unsure whether you need a Level 2 or Level 3, ask the surveyor before booking. A good RICS surveyor will give you an honest view on which level is appropriate for the property you're buying — and may recommend upgrading if they have concerns based on the listing details or photos.
A Level 3 is appropriate for:
What About the Mortgage Valuation?
Your mortgage lender will commission a valuation survey before approving your mortgage. This is not a survey for your benefit — it is for the lender's benefit, to confirm the property is adequate security for the loan.
A mortgage valuation will not identify structural problems, damp, roof condition, or any of the defects that could cost you thousands after completion. It is a brief check, often completed in under 30 minutes.
Never rely on a mortgage valuation as a substitute for commissioning your own survey. The two serve entirely different purposes. Our guide to what a mortgage valuation is and how it differs from a survey explains this in detail.
How to Use Your Survey to Negotiate
A survey that comes back clean is a good outcome. A survey that flags defects is also useful — just in a different way. Any significant issue identified by the surveyor gives you grounds to renegotiate the agreed price before exchange of contracts.
Get quotes for the remediation work identified, and use those quotes to support a revised offer. This is one of the most legitimate moments in the buying process to reduce the price — you're not trying to chip away arbitrarily, you're reflecting the actual condition of the property with evidence.
Our guide to negotiating house price as a buyer covers this in detail, including how to approach a post-survey renegotiation without derailing the sale.
Before you even get to a survey, it's worth knowing whether the asking price is realistic in the first place. Brix&Mortr gives you an independent price check based on real HM Land Registry sold prices for comparable properties — so you're negotiating from a position of knowledge.
Frequently Asked Questions
Do I have to get a survey when buying a house?
No — surveys are optional in England and Wales. However, HomeOwners Alliance research found that 11% of buyers who skipped a survey found problems after moving in and regretted not commissioning one. For most buyers, a survey is a small cost relative to the potential exposure.
What is the most common type of house survey in the UK?
The RICS Level 2 Home Survey is the most commonly chosen option for standard residential purchases. It provides a good balance of depth and cost for conventional properties in reasonable condition.
How much does a house survey cost in the UK?
According to Compare My Move, the average house survey cost in 2026 is £445. Level 1 surveys start from around £300, Level 2 from £400, and Level 3 from £630. Costs increase with property value, size, and location.
When should I book a house survey?
As soon as your offer is accepted. Booking promptly signals commitment to the seller and speeds up the buying process. If the survey reveals significant issues, you have more time to renegotiate or make alternative arrangements before exchange.
Can a house survey fall through a sale?
A survey doesn't directly cause a sale to fall through — but its findings might. If the survey reveals serious structural problems, the buyer may choose to withdraw, renegotiate on price, or ask the seller to carry out repairs before exchange. This is a normal part of the process and preferable to discovering problems after completion.
