Buying a Property

What is a Property Survey, HomeBuyer Report vs Building Survey Explained

A property survey assesses the physical condition of a building before you buy it. Choosing the right level of survey for the property you are buying could save you from a costly and unpleasant surprise after completion.

Why You Need a Survey

A mortgage lender's valuation is not a survey. The valuation tells your lender whether the property is worth the amount they are lending, nothing more. It does not assess the condition of the building or protect you in any way.

A survey, carried out by a qualified RICS-regulated surveyor, provides independent assessment of the property's physical condition. It can reveal issues entirely invisible at a viewing, from damp in the roof space to structural movement behind fresh plasterwork.

RICS Survey Levels Explained

The Royal Institution of Chartered Surveyors (RICS) standardised its survey products in 2021 into three defined levels.

RICS Home Survey, Level 1 (Condition Report)

The most basic survey, intended for new build properties and modern homes in good condition. Provides traffic light ratings (red, amber, green) for different elements but limited commentary. Very few buyers commission a Level 1 survey.

RICS Home Survey, Level 2 (HomeBuyer Report)

The most widely used survey for conventional, reasonably modern properties. Includes:

A visual inspection of all accessible areas
Traffic light condition ratings
Commentary on significant defects and risks
An opinion of market value (in most variants)
Notes on matters requiring further investigation

Appropriate for properties built after approximately 1900, of standard construction, and not showing signs of significant problems.

RICS Home Survey, Level 3 (Building Survey)

The most comprehensive survey, appropriate for:

Properties with visible defects or unusual features
Non-standard construction (timber frame, thatched roof, concrete frame)
Properties over 100 years old
Properties that have been heavily extended or altered
Listed buildings

Involves more detailed inspection, more extensive commentary, and explicit repair advice. Typically does not include a market valuation.

Choosing the Right Level

Property type	Recommended survey level
New build	Snagging survey
Post-war conventional property, good condition	Level 2
Edwardian or older, no visible issues	Level 2 or Level 3
Victorian or older, any visible issues	Level 3
Non-standard construction	Level 3
Listed building	Level 3 + specialist advice

When in doubt, choose Level 3. The additional cost is modest relative to the purchase price and the potential cost of undiscovered defects.

New Build Snagging Surveys

New build properties require specialist snagging surveys rather than standard RICS surveys. These document incomplete or substandard workmanship against the build specification. Common items include poorly fitted doors, incomplete decoration, uneven plastering, and drainage issues.

Snagging surveys should ideally be carried out before legal completion, so the developer is contractually obliged to fix the items.

How to Use a Survey Report

A survey revealing defects is not necessarily a reason to pull out. It is a powerful negotiating tool. If the survey identifies a roof replacement is needed, you can request a price reduction reflecting the cost, ask the seller to carry out the work, or proceed at the agreed price with open eyes.

Property Passport UK allows buyers to review available property documents and historical data before commissioning a survey, helping you brief your surveyor on specific concerns.
