Property Survey Types Explained: RICS Level 1, 2, and 3 for London Buyers
A property survey is one of the most important steps in buying a home in London — yet many buyers skip it or choose the wrong level. This guide explains the three main RICS (Royal Institution of Chartered Surveyors) survey types, what they cover, and which is right for different types of London property.
Why a Survey Matters in London
London's housing stock is varied and old. Victorian and Edwardian terraces dominate many boroughs, and even 1960s and 1970s buildings can carry hidden problems. A mortgage lender's valuation is not a survey — it tells the lender whether the property is worth the loan, not whether it is structurally sound or free from defects.
Without an independent survey, you may buy:
- Serious structural movement or subsidence
- Significant damp penetration
- A flat roof at the end of its life
- Outdated wiring that needs full replacement
- Party wall issues that create future liability
- Chimney stacks in dangerous condition
- Japanese knotweed in the garden
Any of these can cost tens of thousands of pounds to address.
RICS Level 1: Condition Report
The most basic survey — typically used for new-build or near-new properties in excellent condition. It provides a brief overview of visible condition using a simple traffic-light system (condition ratings 1, 2, 3). No advice or valuation is included.
Best for: New builds, recently renovated properties in good condition.
Not recommended for: Victorian or Edwardian property, any building over 20 years old, or any property showing visible signs of issues.
Typical cost in London: £250–£400
RICS Level 2: HomeBuyer Report
The most popular survey for standard residential purchases. A more thorough inspection than the Level 1, covering all accessible and visible parts of the property. It uses the same condition-rating system but provides more detail, advice on defects found, and may include a market valuation.
The HomeBuyer Report will comment on:
- Structural condition (visible)
- Roof condition (from ground level and hatch)
- Damp (with moisture meter readings)
- Timber (rot, woodworm — visible areas only)
- Drainage
- Services (condition of visible pipes, electrics, heating — not tested)
- Significant defects needing urgent attention
It does not include opening up of finishes, testing of services, or investigation of non-accessible areas.
Best for: Conventional properties built after 1900 in reasonable condition, where no significant issues are already visible.
Not recommended for: Heavily extended or altered properties, properties with known structural concerns, any building that is very old or unusual.
Typical cost in London: £500–£900
RICS Level 3: Building Survey (Full Structural Survey)
The most comprehensive survey available. A building surveyor carries out a detailed inspection of all accessible parts of the property, investigates as many areas as reasonably possible, and provides a detailed report on structure, condition, defects (including hidden or latent), and recommended remediation. A building survey does not typically include a market valuation unless specifically commissioned.
The Building Survey will cover:
- Full structural assessment
- Roof structure (loft access)
- Chimney stacks and flues
- Damp penetration in detail (with readings)
- Foundation assessment (including suspected movement)
- Timber condition in detail
- Drainage observation (with optional CCTV drain survey as add-on)
- M&E services observation
- External walls, render, and pointing
- Party walls and boundaries
- Recommendations for specialist investigations if needed
Best for: All Victorian and Edwardian property; any property over 50 years old; properties with extensions; any property where issues have been spotted; unusual construction; high-value purchases.
Typical cost in London: £800–£2,000 depending on size and complexity.
Additional Specialist Surveys
Beyond the RICS levels, you may also need:
- Structural engineer's report: If the building surveyor identifies structural concerns needing specialist assessment
- CCTV drain survey: Particularly important for older London homes where clay drainage is common and can be prone to root ingress and collapse
- Asbestos survey: For properties built before 2000 where refurbishment is planned
- Party wall assessment: If you plan to carry out works affecting shared structure
- Damp and timber specialist report: Where the building surveyor finds significant concern requiring specialist investigation
How to Use Survey Findings
A survey report is a negotiating tool and a planning document. If significant defects are found:
- Get contractor quotes for the identified work before exchanging
- Negotiate the purchase price to reflect the cost of remediation
- Ask the seller to carry out specified repairs before completion
- Walk away if the cost and risk are too high
RCB regularly carries out surveys and assessments on behalf of buyers who want a contractor's eye on a property rather than (or in addition to) a surveyor's formal report. We provide honest opinions on the likely cost of remediation for any property issues identified.
