The main types of house surveys in the UK are usually described through the RICS survey levels: Level 1, Level 2 and Level 3. Each is designed for a different type of property and a different level of detail.
RICS is reviewing its Home Survey Standard, but the first edition remains in force until the second edition takes full effect.
RICS Level 1 Home Survey: a basic condition overview
A Level 1 Home Survey is the least detailed of the three RICS survey levels. It is intended for conventional homes built from common materials that appear to be in satisfactory condition. The report highlights significant visible defects and matters needing attention.
That makes it most suitable for a modern flat, house or bungalow with a straightforward layout and no obvious signs of major alteration or deterioration.
For example, if you are buying a fairly new two-bedroom house on a modern estate and it appears well maintained, Level 1 may provide enough reassurance. If the same property has cracking, damp staining, a converted loft or repeated extensions, moving up a level would usually make more sense.
RICS Level 2 Home Survey: the common middle ground
Level 2 is what many buyers still mean when they ask for a “homebuyer survey” or “HomeBuyer Report”. The formal RICS terminology is now Home Survey Level 2. It is designed for conventional properties in reasonable condition and offers a more extensive inspection and more useful advice than Level 1.
A Level 2 report can identify defects, flag repairs or maintenance, and indicate whether further investigation is needed before exchange. It often suits typical houses and flats that are not especially old, unusual or heavily altered.
Level 2 with or without a valuation
RICS Level 2 can be provided as survey only or as survey plus valuation. The valuation version can include a market valuation and an insurance reinstatement figure. If you want those figures, check that they are included in the quotation rather than assuming every Level 2 survey comes with them.
A mortgage lender’s valuation is different. It is primarily for the lender to assess the property as security for the loan, so it is not a substitute for a survey commissioned to help you understand the home’s condition.
RICS Level 3 Home Survey: the most detailed option
A Level 3 Home Survey is the most comprehensive RICS home survey and is the modern equivalent of what many people still call a building survey. It is intended for older, larger, unusual, run-down or significantly altered homes, as well as properties where major renovation is planned.
The report goes further into construction, visible defects, repair options and future maintenance. Where safe and accessible, the surveyor investigates more thoroughly than at Levels 1 or 2. Services are observed but are not fully tested in the way a specialist electrician, gas engineer or drainage contractor would test them.
If you are considering a Victorian terrace with signs of movement, an older stone cottage or a house with several extensions, Level 3 is normally the stronger starting point. The extra detail can help you decide whether to proceed, renegotiate or commission specialist reports.
How to choose between Level 1, Level 2 and Level 3
The best survey is not determined by purchase price alone. Age, construction, condition, alterations and your own plans for the property matter more. A relatively inexpensive period house can justify Level 3, while a costly modern apartment may only need Level 1 or Level 2.
Level 1 suits straightforward modern homes in good condition; Level 2 suits conventional homes where you want meaningful detail without a full building survey; and Level 3 suits older, unusual, altered or problematic homes, or purchases where you want the deepest available condition assessment.
Before booking, tell the surveyor about anything you noticed during viewings. A stain beneath a bathroom, cracks around an extension, a flat roof, a cellar smell or an old electrical installation can all affect the advice you need. Asking “which level would you recommend for this specific property, and why?” is more useful than simply requesting the cheapest report.
Other reports buyers often confuse with a house survey
A new-build snagging inspection is designed to identify defects, poor finishes and incomplete work in a newly constructed home. It can be useful around completion, but it is a separate service rather than one of the standard RICS Home Survey levels.
Specialist reports may also be recommended after a general survey, including structural engineer reports, damp or timber investigations, electrical inspections, drainage surveys or asbestos surveys. A home survey does not replace every specialist test.
Buyers in Scotland should also be aware of the Home Report system. Most homes marketed for sale must have a seller-provided Home Report containing a Single Survey and valuation, an Energy Report and a Property Questionnaire. That changes the buying process compared with England, Wales and Northern Ireland, although additional professional advice may still be sensible when concerns arise.
Useful internal topics to explore alongside this guide include house buying legal process, conveyancing searches explained, and what a conveyancer does when buying a home.
Frequently asked questions
Is a Level 2 survey enough for an older house?
Sometimes. A conventional older home in good condition may be suitable for Level 2, but traditional construction, significant alterations, visible defects or poor maintenance can make Level 3 the better choice. Ask the surveyor before instructing them.
Is a building survey the same as a Level 3 survey?
In current RICS terminology, Level 3 is the most detailed RICS Home Survey and broadly replaces the older RICS “Building Survey” wording. Many firms and buyers still use “building survey” informally.
Does a house survey include a property valuation?
Not automatically. Level 2 is available with a valuation option, while Level 1 and the standard Level 3 report do not inherently include a market valuation. Always check the surveyor’s quotation and terms of engagement.
Can a survey guarantee there are no hidden defects?
No. Home surveys are inspections with defined limits, not guarantees that every concealed defect will be found. Access, floor coverings, furniture, finishes and safety restrictions can prevent parts of a property from being inspected. The report should explain significant limitations.
Choosing the survey that matches the property
The simplest way to compare UK house surveys is to match the depth of the inspection to the risk in the property. Level 1 is a light condition check, Level 2 is the everyday homebuyer survey for conventional homes, and Level 3 is the detailed choice for properties that are older, altered, unusual or in poorer condition. When in doubt, describe the property to the surveyor before booking and ask what level they recommend. The right survey should help you make a better buying decision, not simply produce another document for the file.
