House Survey Types Explained
Key Summary
- There are three main RICS house survey levels — Level 1, Level 2, and Level 3 — each suited to different property types and buyer needs.
- A Level 2 HomeBuyer Survey is the most popular choice and suits modern, conventionally built homes in reasonable condition.
- A Level 3 Building Survey is the most thorough option and is recommended for older, period, or non-standard properties.
- A mortgage valuation is not a survey and does not protect the buyer.
- Choosing the wrong survey level for your property could leave you unaware of significant issues before purchase.
What Is a House Survey?
A house survey is a professional inspection of a property carried out by a qualified surveyor. Its purpose is to assess the condition of the building and report on any defects, risks, or areas requiring further investigation before you commit to the purchase. In England and Wales, most surveys are carried out under the RICS Home Surveys Standard, which sets out three survey levels. Each level varies in the depth of inspection, the detail of the report, and the type of property it is designed for. It is also worth being clear about one thing from the outset: a mortgage lender’s valuation is not a survey. It is a report prepared for the lender’s benefit, not yours. It tells the bank whether the property is suitable security for a loan. It tells you very little about the actual condition of the building.RICS Level 1 Survey
A Level 1 survey, sometimes called a Condition Report, is the most basic option available. It provides an overview of the property’s condition using a simple traffic light rating system, but it contains no advice, no commentary on defects, and no recommendations. It is generally suitable only for new-build properties or very recently renovated homes where you have very high confidence in the condition of the building. For most buyers, it provides too little information to be genuinely useful.RICS Level 2 HomeBuyer Survey
The Level 2 HomeBuyer Survey is the most widely used house survey type in England and Wales. It builds on the Condition Report by adding written commentary, advice on defects, and recommendations for further investigation where needed. It also uses the same traffic light rating system to flag the severity of any issues. A Level 2 survey covers the visible and accessible parts of the property, including the roof, external walls, windows, doors, internal walls, floors, ceilings, roof space, drainage, and services. The surveyor will note anything that requires attention and explain what the implications might be if it is left unaddressed. This survey level is best suited to:- Modern properties built from around the 1930s onwards
- Conventionally constructed homes in a reasonable state of repair
- Buyers who want a clear, readable overview of a property without a full structural investigation
RICS Level 3 Building Survey
A Level 3 Building Survey is the most detailed and comprehensive survey available. It goes well beyond the Level 2 in terms of both the inspection itself and the depth of reporting. The surveyor will examine the construction, materials, and condition of the building in much greater detail. They will look at how the property has been built, comment on the nature and cause of defects, assess the likely remedial works required, and advise on the urgency of any action needed. At Skylark Surveyors, we also make use of drones and the latest inspection technology to assess high-level areas that would otherwise be inaccessible. A Level 3 Building Survey is the recommended choice for:- Victorian, Edwardian, and other period properties
- Listed buildings and buildings of historic significance
- Properties that have been significantly extended, converted, or altered
- Homes in poor condition or with visible defects
- Non-standard construction, including timber framed, steel framed, or thatched properties
- Any property where you want the most thorough assessment possible before committing
Other Survey and Valuation Types
Specific Defect Survey
A Specific Defect Survey is focused on a single element of the property rather than providing an overall condition assessment. It is useful if you already own a property and want an expert opinion on a particular concern, such as cracking, damp, or a roof defect, without commissioning a full survey.RICS Valuations
RICS valuations are separate from surveys and are used for specific purposes, including Help to Buy redemption, shared ownership staircasing, probate and inheritance tax, and capital gains tax. These are formal RICS-compliant reports prepared by a registered valuer and carry legal and financial weight.Roof Surveys
A roof survey provides a detailed assessment of the roof covering, structure, and associated elements. At Skylark Surveyors, we use drone technology to inspect roof slopes safely and thoroughly, without the need for scaffolding in most cases.Do I Need a Survey When Buying a House?
You are not legally required to commission a survey when buying a property in England and Wales. However, it is strongly advisable for most purchases. Buying a home is likely to be the largest financial commitment of your life, and a survey gives you independent professional advice on what you are actually buying. The cost of a house survey is relatively modest compared to the potential cost of defects discovered after you have moved in. Issues such as damp, structural movement, or roof deterioration can run to tens of thousands of pounds to rectify properly. A survey gives you the information you need to make an informed decision, renegotiate if appropriate, or walk away if the property is not what it first appeared. The government’s guide to surveys and valuations also provides a straightforward overview for buyers who want to understand their options before approaching a surveyor.
Choosing the Right Survey for Your Property
The most common mistake buyers make is choosing a Level 2 survey for a property that really warrants a Level 3. The temptation to save a little money on the survey fee is understandable, but it can be a false economy if the property has issues that only a more thorough inspection would uncover. As a rule of thumb, if you are buying a property built after the 1930s in reasonable condition and you have no specific concerns, a Level 2 HomeBuyer Survey is likely to serve you well. If the property is older, has had significant alterations, or shows any visible signs of defects, a Level 3 Building Survey is the safer choice. If you are unsure which option is right for your purchase, the team at Skylark Surveyors is always happy to talk it through before you book. We provide surveys across Surrey, Hampshire, and Berkshire, and we will give you a straight answer based on the specifics of the property rather than a one-size-fits-all recommendation.

You are not legally required to commission a survey, but it is strongly recommended. A survey gives you an independent professional assessment of the property’s condition before you commit. Without one, any defects discovered after completion are your responsibility to deal with and pay for.What is the difference between a HomeBuyer Survey and a building survey?

A building survey is a Level 3 inspection that provides a much deeper assessment of the construction, materials, and condition of the property.
