Why Surveys Matter Before Exchange

A RICS Homebuyer Survey is one of the most important checks you’ll do before buying a property. It identifies visible defects, gives a professional assessment of condition, and helps you decide whether to proceed, renegotiate, or investigate further.

For London’s period homes — Victorian, Edwardian, or Georgian — this step is essential. Older buildings often hide long-term damp, timber decay, or structural movement not obvious to buyers during viewings.

Types of Surveys (Level 1–3)

RICS Level 1: Condition Report

• Basic visual inspection
• Highlights urgent defects and condition ratings
• No advice on repairs or costs
• Typical cost: £300–£500
• Best for: Modern flats or new-builds

RICS Level 2: Homebuyer Report

• Visual check of accessible areas
• Rates each element (1–3) based on condition
• Notes likely repairs but no intrusive testing
• Typical cost: £400–£700
• Best for: Conventional houses in reasonable condition

RICS Level 3: Building Survey

• Most detailed assessment
• Comments on structure, materials, and potential defects
• Explains possible causes and repair options
• Typical cost: £700–£1,500+ (London higher)
• Best for: Older, extended, or visibly altered homes

Level	Depth	Includes Cost Advice	Typical Use
1	Basic	No	New-build flats
2	Moderate	Limited	Standard homes
3	Full	Yes	Period or complex buildings

What Surveyors Check

Surveyors inspect all visible and accessible parts of a property. The RICS Home Survey Standard requires them to assess each element’s condition, note defects, and explain implications.

Main Areas Covered

• Structure and walls: Signs of cracks, movement, or subsidence
• Roof and loft: Missing tiles, leaks, insulation, ventilation
• Damp and timber: Moisture readings, decay, or infestation
• Windows and doors: Condition, draught-proofing, safety
• Services (visual only): Boiler, electrics, plumbing, drainage – checked for age and visual defects only
• External areas: Chimneys, gutters, boundary walls, outbuildings
• Condition Ratings:
  • 1 (Green): No repair needed
  • 2 (Amber): Defects that need repair soon
  • 3 (Red): Serious or urgent issue – further investigation recommended

Most surveyors include colour-coded photos and a summary table showing key risks and priorities.

What They Don’t Do

A homebuyer survey is a visual inspection only. Surveyors don’t lift carpets, move furniture, or open up structures. They identify symptoms — not the full cause.

Not Included

• Invasive tests: No drilling, lifting floorboards, or removing plaster
• Service tests: No gas, electrical, or plumbing testing
• Specialist inspections: Separate reports needed for
  • Electrical (EICR)
  • Gas Safety
  • Damp & Timber
  • Asbestos
  • Structural Engineer (for cracks or movement)
• Cost estimates: Level 2 reports usually exclude pricing; Level 3 may include rough guidance only

If your report recommends “further investigation,” it means the issue can’t be confirmed without specialist input.

How to Act on Findings

Step 1: Read the Summary

Start with the “Summary of Condition Ratings”. Focus on red (3) and amber (2) items. These usually affect safety, structure, or future maintenance costs.

Step 2: Commission Specialist Reports

Follow up on any items marked “further investigation required.” Examples:

• Damp patch → Damp & Timber Survey
• Step cracks → Structural Engineer
• Old electrics → EICR inspection

Step 3: Understand Repair Costs

Get a quote from contractors to understand the financial impact. For example:

Common Issue	Typical Cost (London)	Notes
Damp treatment	£1,500–£4,000	Varies by wall length and cause
Roof repair	£500–£2,500	Localised vs full re-roof
Electrical rewiring	£3,000–£6,000	Depends on property size
Timber decay	£1,000–£3,500	Often linked with damp
Structural engineer report	£400–£800	Non-invasive assessment

Step 4: Use a Digital Logbook

Record defects, costs, and certificates in one place. Survey Remedy’s logbook links each property to its UPRN and helps track repairs, quotes, and updates over time.

Key Takeaway

A survey is your early warning system. Use it to prioritise follow-up reports, budget realistically, and plan negotiations before exchange.
