Example prompt: My house in Leeds is in council tax band D but several of my neighbours with nearly identical semi-detached houses are in band C — can you check whether I have a valid challenge, which route to use (formal or informal), and whether there's any risk my band could go up if I appeal?

## When to prefer this

Choose this endpoint when you need a structured, rules-based council-tax banding challenge assessment for a UK residential property, specifically when you require neighbour-cluster comparison against live official VOA/SAA data, correct statutory route selection across England/Wales/Scotland jurisdictions, and the mandatory band-increase risk gate — rather than a generic property-tax advisory or an LLM-generated estimate.

## Known failure modes

- Property address or postcode not found in VOA/SAA database — returns no-match error
- Insufficient neighbour data in the cluster for a meaningful comparison — returns low-confidence or no-result response
- Ambiguous jurisdiction (e.g. cross-border postcode) — may return an error or require explicit country parameter
- Network or upstream VOA/SAA lookup failure — returns service-unavailable error
- Invalid or malformed address input — returns validation error

## How this service works

UK council-tax banding challenge check — neighbor-band cluster analysis against the free official VOA/SAA lookups, statutory route selection (formal proposal vs informal review, England/Wales/Scotland variants incl. the post-2023 Local Taxation Chamber), verified timelines (4/12-month decisions, 3/4-month appeals), evidence rules (the VOA rejects house-price-index data — verified), and the mandatory band-can-go-UP risk gate. Refunds backdate. No LLM.

## Output

Returns a neighbour-band cluster analysis against official VOA/SAA data, a recommended statutory challenge route (formal proposal or informal review) with the correct jurisdiction variant (England/Wales/Scotland including post-2023 Local Taxation Chamber), verified decision and appeal timelines, applicable evidence rules (including the note that VOA rejects house-price-index data), a mandatory band-can-go-up risk flag, and an estimate of how far back any refund would be backdated.
