Model Risk / Vendor Due Diligence
Current accuracy figures are published live on our Accuracy page, always matching the model in production. Full vendor due-diligence documentation is available on request to organisations conducting model-risk review.
Sample Reports
Real valuations of real UK properties, marked SAMPLE on every page. The set is deliberately contrasting — strong evidence, weak evidence, and a property the model declined to value — so you can see exactly how the report behaves before you buy.
Fitch Band A
No sample available — the model has not yet produced a Band A valuation (none in the current test). When it does, a sample will appear here.
Fitch Band B — Strong Evidence
Dense local sale and rental evidence produces a tight valuation range and a Band B confidence rating. B13 0DW, valued at £237,344.
Ref GV-20260728-00019
Fitch Band C — Standard Case
A typical mid-band result: solid sale comparables with thinner rental evidence, mapped to Band C. BS3 1FH, valued at £280,242.
Ref GV-20260728-00020
Fitch Band D — Honest Weak Case
No Band D properties currently exist
No-Value Response
What you receive when the model declines to value rather than return an unreliable figure: the decline reason and guidance to route the property onward in your valuation cascade. No valuation is consumed.

What's in the report
Property Details
The report begins with the property's address, postcode, type, floor area, and EPC rating (where available). This data is sourced from the national EPC register and Land Registry records.
Estimated Market Value
The headline figure: a point estimate of current market value in pounds sterling. Below it, a prediction range shows the upper and lower bounds reflecting model uncertainty for this specific property.
Confidence Assessment
Every valuation carries a per-property Forecast Standard Deviation (FSD) based on comparable evidence quality, data completeness, and prediction certainty, mapped to a Fitch A–D classification band. A lower FSD means stronger evidence and a tighter range.
Comparable Properties
A table of nearby recent sales used by the model, showing address, distance from the subject property, sale date, sale price, property type, and floor area. This gives you the same evidence a surveyor would use for a comparison-based valuation.
Feature Contributions
An explainability breakdown showing which property characteristics pushed the valuation up or down relative to the local median. This is derived from SHAP (SHapley Additive exPlanations) analysis of the model's decision.
Methodology & Disclaimer
Every report includes a plain-language explanation of the model methodology, data sources used, and a clear disclaimer stating this is an AVM estimate, not a formal valuation. Full data provenance information for regulatory and due diligence purposes.
