Last reviewed: 15 July 2026. This guide is general information, not professional or legal advice. Survey types, names and costs can change, so confirm the current position with a qualified surveyor and the official sources linked below before you rely on it.
A house survey is an independent inspection of a property by a qualified surveyor, carried out for you, the buyer. It tells you what condition the building is really in - the defects, the risks and the things worth investigating further - so you can proceed with confidence, renegotiate, or walk away. The right level of survey depends mostly on the age, type and condition of the home you are buying.
Surveys work differently in Scotland. Most Scottish homes are marketed with a Home Report, which already contains a single survey and valuation commissioned by the seller (s.98, Housing (Scotland) Act 2006), so a Scottish buyer often does not need to commission the survey types described below. This guide describes the position in England and Wales.
A mortgage valuation is not a survey
This is the single most common misunderstanding in the buying process. When you take out a mortgage, your lender arranges a valuation - but as RICS explains, "a mortgage valuation is for the benefit of the lender, not the home buyer/owner, and it won't include the same level of detail as a survey." Its job is simply to confirm the property is worth enough to secure the loan. It will not tell you about damp, roof problems, movement, or old wiring, and you may never even see a copy. If you want to understand the condition of the home, you commission your own survey.
The three levels of RICS home survey
Residential surveys in the UK are organised around the RICS Home Survey Standard, which has three levels, increasing in depth and price as you go up. In 2025 RICS ran a consultation on updating this standard, so the way the levels are described may change over time and you could see newer wording (proposals discussed have included describing them as basic, intermediate and advanced). Either way, the substance below is what matters.
Level 1 - the most basic (formerly the Condition Report)
A Level 1 survey describes the condition of the property, flags any risks and potential legal issues, and highlights urgent defects. It does not go into detailed advice or repairs. RICS says it is most suitable for conventional properties and newer homes in good condition where you just want reassurance there is nothing obviously serious wrong.
Level 2 - the mid-level (formerly the HomeBuyer Report)
A Level 2 survey gives more detail: the condition of the accessible parts of the building, and ideas about future repairs and maintenance. RICS says it is most suitable for conventional properties in reasonable condition that are simple in form and layout. It comes in two versions - a survey only, and a survey and valuation that adds a market valuation and an insurance reinstatement figure. This is the most popular choice for typical homes.
Level 3 - the most thorough (formerly the Building Survey)
A Level 3 survey is the most comprehensive report. It inspects the accessible and visible parts of the building in detail, explains the cause of defects, and sets out the likely consequences of not acting. RICS recommends it if you are dealing with a large, older or run-down property, a building that is unusual or has been altered, or if you are planning major works.
Which level should I choose?
As a rough guide, match the level to the property. If in doubt, go up a level - the extra cost is small next to the cost of a problem you did not know about.
| Property | Level to consider |
|---|---|
| New build or modern home in good condition | Level 1 - or a new-build snagging inspection |
| Conventional house in reasonable condition | Level 2 |
| Older or period property (for example Victorian or Edwardian) | Level 2 or Level 3 |
| Large, run-down, unusual, listed or heavily altered property | Level 3 |
| Any home with visible damp, cracks or roof concerns, or where you plan major works | Level 3 |
What does a survey cost?
Survey fees vary with the property's size, value, location and the level of survey. RICS's own guidance puts Level 1 as "starting at a few hundred pounds", with the most detailed Level 3 bespoke services "costing over £1000" (RICS consumer guide).
For a rough sense of typical prices, one UK survey comparison service published average figures from its own users for a typical home worth around £292,000. These are illustrative user data, not an industry standard, and your quotes will differ:
| Survey type | Illustrative typical fee |
|---|---|
| New-build snagging survey | around £394 |
| Valuation report | around £354 |
| Level 2 survey | around £499 |
| Level 3 survey | around £656 |
The practical takeaway: always get a few quotes from different firms for the same level of survey, and compare what is included rather than price alone. RICS's advice is to shop around and ask for quotes from different RICS firms.
Who should carry out the survey?
Look for a surveyor regulated by RICS (the Royal Institution of Chartered Surveyors). "Chartered Surveyor" is a protected title that, as the GOV.UK Regulated Professions Register confirms, "may be awarded only by the Royal Institution of Chartered Surveyors (RICS)." Worth knowing: surveying has no "reserved activities" in law, so someone can practise without the RICS title - which is exactly why the RICS regulation, and the surveyor's professional indemnity insurance, are the trust signals to check for. It is also sensible to be cautious about a surveyor recommended solely by the party selling to you, and to ask whether any referral fee is involved - our guide on questions to ask your surveyor covers this.
Can I use the survey to renegotiate?
Yes. If a survey uncovers significant problems - a failing roof, movement, serious damp or old electrics - you can use the written findings to renegotiate the price, ask the seller to carry out works before completion, or in a serious case withdraw. Sellers are not obliged to reduce the price, but many are open to a reasonable conversation when there is evidence in writing.
Frequently asked questions
Is a mortgage valuation the same as a survey?
No. A mortgage valuation is carried out for your lender's benefit to confirm the property is worth enough to secure the loan; RICS states it "won't include the same level of detail as a survey." It will not assess condition, damp, the roof or the wiring, and you may not receive a copy. A survey is commissioned by and for you to understand the property's actual condition.
What are the three survey levels?
The RICS Home Survey Standard has Level 1 (a basic condition report, best for newer conventional homes in good order), Level 2 (a more detailed report for conventional homes in reasonable condition, available survey-only or with a valuation), and Level 3 (the most comprehensive, for large, older, unusual, altered or run-down properties). RICS ran a consultation on updating this standard in 2025, so the level descriptions may change over time and you may see newer wording alongside the Level 1/2/3 names.
How much does a house survey cost?
It depends on the level, and the property's size, value and location. RICS puts Level 1 at "starting at a few hundred pounds" and the most detailed Level 3 bespoke services at "over £1000". Illustrative comparison-site figures for a typical ~£292,000 home were around £499 for a Level 2 and £656 for a Level 3, but these are not a standard - always get your own quotes.
Do I need a survey on a new-build home?
A new build usually comes with a warranty, but a survey or, more commonly, a snagging inspection still helps you spot unfinished or defective work before and after you move in. See our guide to new-build snagging surveys.
Does my surveyor have to be RICS-regulated?
There is no legal requirement - surveying has no reserved activities, so anyone may practise. But only RICS can award the "Chartered Surveyor" title, and choosing an RICS-regulated surveyor with professional indemnity insurance is the accepted way to know you are dealing with a qualified, accountable professional.
