Measured tools (11)

• search_property read-only

  Find candidate properties by address or postcode. Always call this first and confirm the match with the user before running other tools — never guess which property was meant.

  Parameters:

  • query (required) — string — Free-text address or postcode, e.g. "14 Acacia Road, CV4 7AL" or "CV4 7AL"

  Hints: read-only yes · destructive not declared · idempotent not declared · open-world not declared

• get_property_summary read-only

  One-call overview of a property: EPC headline, last sale, flood risk, LPA, planning-risk score and council tax band. Start here after disambiguating with search_property.

  Parameters:

  • property_id (required) — string — The property id returned by search_property (an EPC certificate lmk-key). Prefer this over re-supplying a postcode once you have it.

  Hints: read-only yes · destructive not declared · idempotent not declared · open-world not declared

• get_epc_history read-only

  All EPC certificates lodged for a property over time, with floor area, room counts and rating per certificate. A floor-area jump between certificates with no matching planning record is the single highest-value red flag for a cash buyer.

  Parameters:

  • property_id (required) — string — The property id returned by search_property (an EPC certificate lmk-key). Prefer this over re-supplying a postcode once you have it.

  Hints: read-only yes · destructive not declared · idempotent not declared · open-world not declared

• get_price_history read-only

  HM Land Registry Price Paid transaction history for a property or postcode.

  Parameters:

  • address — string — House number/name to narrow results within the postcode
  • postcode — string — UK postcode — required if property_id is not given
  • property_id — string — The property id returned by search_property (an EPC certificate lmk-key). Prefer this over re-supplying a postcode once you have it.

  Hints: read-only yes · destructive not declared · idempotent not declared · open-world not declared

• get_area_market read-only

  UK House Price Index and local market trend (price growth, transaction velocity, property mix) for a postcode area.

  Parameters:

  • postcode (required) — string — UK postcode or outcode, e.g. "CV4 7AL" or "CV4"

  Hints: read-only yes · destructive not declared · idempotent not declared · open-world not declared

• get_flood_risk read-only

  Environment Agency flood zone (river/sea) and surface-water risk for a property, reported separately. Returns an explicit absent state rather than a false "low" when EA has no data for the location.

  Parameters:

  • postcode — string — UK postcode — required if property_id is not given
  • property_id — string — The property id returned by search_property (an EPC certificate lmk-key). Prefer this over re-supplying a postcode once you have it.

  Hints: read-only yes · destructive not declared · idempotent not declared · open-world not declared

• get_planning_history read-only

  Nearby planning applications and decisions, plus a rule-based planning approval-likelihood score for the area.

  Parameters:

  • postcode — string — UK postcode — required if property_id is not given
  • property_id — string — The property id returned by search_property (an EPC certificate lmk-key). Prefer this over re-supplying a postcode once you have it.

  Hints: read-only yes · destructive not declared · idempotent not declared · open-world not declared

• get_broadband read-only

  Ofcom broadband and mobile coverage for a postcode. Requires a HouseData API key. Live-checked per call, so this can take several seconds — do not call it in a tight loop over many postcodes.

  Parameters:

  • postcode (required) — string — UK postcode

  Hints: read-only yes · destructive not declared · idempotent not declared · open-world not declared

• get_prism_score read-only

  Housedata PRISM score: identifies where a property's features (extensions, conversions, floor-area changes) lack a corresponding planning/building-control record, with remediation paths. Requires an active HouseData API key — if the account is not entitled, the error explains how to upgrade.

  Parameters:

  • postcode — string — UK postcode — required if property_id is not given
  • property_id — string — The property id returned by search_property (an EPC certificate lmk-key). Prefer this over re-supplying a postcode once you have it.

  Hints: read-only yes · destructive not declared · idempotent not declared · open-world not declared

• check_epc_compliance read-only

  Batch-checks up to 50 properties (by id or postcode) against Minimum Energy Efficiency Standard (MEES) 2030 thresholds and flags expired certificates. Use for landlord portfolio compliance sweeps.

  Parameters:

  • items (required) — array — Property ids and/or postcodes, up to 50

  Hints: read-only yes · destructive not declared · idempotent not declared · open-world not declared

  Hints: read-only yes · destructive not declared · idempotent not declared · open-world not declared
