Understanding RICS Guidance for Spray Foam (And Why It Matters)
The Royal Institution of Chartered Surveyors (RICS) guidance on spray foam insulation has fundamentally changed how properties are valued and mortgaged in the UK. Understanding this guidance is crucial for any homeowner dealing with spray foam issues.
What Is RICS and Why Does Their Guidance Matter?
About RICS
The Royal Institution of Chartered Surveyors is the UK's leading professional body for property professionals. Their guidance carries significant weight because:
- Mortgage lenders rely on RICS-qualified surveyors for property assessments
- Insurance companies follow RICS standards for risk evaluation
- Legal professionals reference RICS guidance in property disputes
- Property professionals are required to follow RICS standards
Why Spray Foam Guidance Was Needed
The guidance was developed due to:
- Increasing mortgage refusals for properties with spray foam
- Inconsistent surveyor reporting across the industry
- Insurance concerns about fire and health risks For more information, see our detailed FAQ about health and safety.
- Building regulation compliance questions

What Surveyors Must Report Under RICS Guidance
Mandatory Reporting Requirements
1. Presence and Location
Surveyors must identify:
- Type of spray foam (open-cell vs. closed-cell)
- Application areas (roof space, walls, floors)
- Extent of coverage (percentage and thickness)
- Installation quality and visible defects
2. Risk Assessment Factors
Required evaluation of:
- Fire safety implications based on foam type and location
- Structural impact on building ventilation and moisture
- Access restrictions for maintenance and emergency services
- Building regulation compliance status
3. Condition Assessment
Surveyors must note:
- Foam degradation or damage
- Associated problems (dampness, timber issues)
- Ventilation impacts and condensation risks
- Maintenance accessibility concerns
Surveyor Risk Classification System
Category 1: Low Risk
- Professional installation with documentation
- Appropriate foam type for application
- No visible defects or associated problems
- Building regulation compliance confirmed
Typical outcome: May proceed with standard mortgage conditions
Category 2: Medium Risk
- Installation quality concerns requiring investigation
- Missing documentation about compliance
- Minor associated problems (ventilation, access)
- Uncertainty about regulation compliance
Typical outcome: Specialist report required before mortgage approval
Category 3: High Risk
- Poor installation with visible defects
- Inappropriate foam type for application
- Significant associated problems (structural, fire safety)
- Clear building regulation violations
Typical outcome: Mortgage refusal until issues For more information, see our detailed FAQ about mortgage impact. resolved
How RICS Guidance Affects Mortgage Applications
Lender Response to RICS Reports
When Spray Foam Is Flagged
Lenders typically respond by:
- Requesting specialist reports from approved consultants
- Applying mortgage conditions requiring resolution
- Reducing loan-to-value ratios to limit exposure
- Refusing applications for high-risk properties
Specialist Report Requirements
When triggered, lenders may require:
- Structural engineer assessment of building integrity
- Building control confirmation of regulation compliance
- Fire safety evaluation by qualified professionals
- Air quality testing if health concerns exist
Timeline Impact on Property Transactions
Standard Process Delays
- Initial survey flagging: Adds 1-2 weeks
- Specialist report commissioning: 2-4 weeks
- Report completion: 2-6 weeks depending on complexity
- Lender review: 1-2 weeks
- Total delay: 6-14 weeks additional time
Emergency Accelerated Process
Some lenders offer:
- Fast-track specialist reviews (additional cost)
- Preferred consultant panels for quicker turnaround
- Conditional approvals pending report outcomes
What Properties Are Most Affected
High-Risk Property Types
Residential Properties
