Key Changes in Valuation Practice Statements
The Red Book Valuation Standards for 2026: RICS Updates for Accurate Property Assessments include a significant restructuring of Valuation Practice Statements (VPS) to improve logical flow and usability for practitioners conducting everything from probate valuations to complex commercial assessments.
VPS Renumbering and Reorganization 📋
The new VPS structure effective January 31, 2025:[7]
| Previous Number | New Number | Statement Title |
|---|---|---|
| VPS 1 | VPS 1 | Terms of engagement (unchanged) |
| VPS 2 | VPS 4 | Inspections, investigations and records |
| VPS 3 | VPS 6 | Valuation reports |
| VPS 4 | VPS 2 | Bases of value |
| – | VPS 3 | Valuation approaches and methods |
| – | VPS 5 | Valuation review and quality assurance |
This reorganization places bases of value earlier in the sequence, reflecting its foundational importance to the valuation process. The new VPS 5 on valuation review and quality assurance represents an entirely new addition, emphasizing the importance of internal quality control procedures.[7]
Enhanced Inspection and Investigation Requirements
VPS 4 (formerly VPS 2) now includes strengthened requirements for property inspections, particularly relevant for RICS building surveys and specialist assessments. Surveyors must:
✅ Document the extent and limitations of their inspection clearly
✅ Record observable ESG-relevant factors during site visits
✅ Identify and note any AI-assisted data collection methods used
✅ Maintain comprehensive records of all investigations and data sources
✅ Clearly state assumptions where direct inspection was limited or not possible
These requirements ensure transparency and provide clients with clear understanding of what the valuation encompasses and its limitations.
Technology and AI Integration in Valuation Practice
One of the most forward-thinking aspects of the Red Book Valuation Standards for 2026: RICS Updates for Accurate Property Assessments is the explicit recognition and governance of AI and advanced technology in valuation processes.
When Can Surveyors Use AI? 🤖
The updated standards permit AI and advanced technology usage in valuations, provided that:
- Human professional judgment remains central to all valuation conclusions
- Appropriate governance frameworks are established and maintained

Expanded Comparable Data Sources 📊
The Red Book Valuation Standards for 2026: RICS Updates for Accurate Property Assessments now explicitly allow comparable property information to include:
- Key performance indicators (KPIs) from property databases
- Metrics and benchmarking data from specialized service providers
- Market intelligence platforms and aggregated transaction data
- ESG performance databases and sustainability ratings
This expansion increases consistency and better aligns with global reporting standards, though professional judgment remains essential in determining the reliability and relevance of such data sources.[1]
Mandatory Data Management Standards 🔒
As valuers increasingly rely on multiple data sources—from traditional comparables to AI-generated insights—the updated Red Book introduces mandatory data management standards to ensure:
| Requirement | Purpose | Implementation |
|---|---|---|
| Transparency | Clear disclosure of data sources | Document all sources in valuation reports |
| Confidentiality | Protection of sensitive information | Secure data handling protocols |
