UK Property Data

Search Companies House for a company by name.

Fetch a single EPC certificate by its GOV.UK certificate number.

Use after property_epc_summaries has listed the candidates and you have picked one — this is faster than property_epc(postcode, address) as it makes a direct lookup with no address matching or postcode re-fetch.

The parameter is named lmk_key as a compatibility alias; pass the certificate number, which is returned in every property_epc_summaries row. (property_epc_search is deprecated and raises — do not call it.)

Returns the full EPC certificate, or null only when no such certificate is lodged. A null result means no such certificate is lodged. If the EPC service cannot be reached the tool raises an error instead — never treat an error as evidence that a property has no certificate.

Find the council planning portal URL for a postcode.

Land Registry Price Paid transactions for a postcode, most recent first.

Returns up to limit most recent transactions within snapshot coverage (coverage_from-coverage_to in the response's provenance). Unfiltered by default -- category-B bulk transfers and commercial sales are included. Pass property_type (F=flat, D=detached, S=semi, T=terraced, O=other) to restrict the result to a single type.

Not a complete property history. Check provenance.older_records_exist and provenance.sample_complete before saying anything about what a property has or has not sold for. An empty result means "no sales within the stated coverage" -- never "never sold". For clean residential comparable sales, use property_comps.

Property block analysis — identify buildings with multiple flat sales (block-buy opportunities).

Comparable sales from Land Registry Price Paid Data.

Defaults return the standard residential set:

• property_type=None means residential (F+D+S+T). Pass "F"/"D"/"S"/"T"/"O" for a single type, or "ALL" to disable type filtering (firehose).

• transaction_category defaults to "A" (standard sales). Pass None to include category-B (bulk transfers, non-standard conveyances).

• filter_outliers=False by default; set True for IQR-trimmed stats AND transaction list (1.5*IQR rule, needs >=4 prices).

limit caps returned transactions (max 200). enrich_epc attaches EPC floor area and price-per-sqft to each transaction — slower but richer.

Energy Performance Certificate data for a UK property or postcode area.

With address: returns the matched EPC certificate for that specific property. Without address: returns the record count and, when the bounded response contains every matching summary, the rating distribution. Property-type breakdown and floor-area statistics are NOT available — the EPC service exposes them only on individual certificates.

Returns null only when no certificates are lodged for the postcode. A null result means no such certificate is lodged. If the EPC service cannot be reached the tool raises an error instead — never treat an error as evidence that a property has no certificate.

DEPRECATED — use property_epc_summaries then epc_certificate.

This tool returned score, floor_area, property_type, habitable_rooms and inspection_date for every certificate at a postcode. The EPC service no longer exposes those fields in a search: they exist only on a full certificate. Reproducing the old response would require one upstream request per certificate, so this tool is unsupported rather than silently degraded or silently expensive.

List EPC certificate summaries at a postcode — for candidate selection.

Returns one bounded page. Each entry contains only what the EPC search exposes: certificate_number, address, uprn (often absent), energy band, registration_date and schema_type. Energy score, floor area and property type are NOT available here — fetch a specific certificate for those.

Workflow when a Rightmove listing has no house number:

1. property_epc_summaries(postcode) to list candidates.

2. Narrow by address text and, where present, uprn.

3. epc_certificate(lmk_key=<certificate_number>) for the chosen one, then cross-check its floor_area against the listing.

4. If several candidates remain equally plausible, present them all — do not guess. Selecting arbitrarily attaches another property's data.

complete is false when the postcode holds more records than this page returns. Upstream page traversal is not snapshot-stable, so a multi-page result is a bounded sample, not a guaranteed-complete set.

An empty results list means no certificates are lodged. If the EPC service cannot be reached the tool raises an error instead — never treat an error as evidence that a property has no certificate.

Gross rental yield for a UK postcode.

Combines Land Registry sale comps (median sale price) with Rightmove rental listings (median monthly rent) to produce a gross yield percentage.

Rental market analysis and achievable rent estimate.

auto_escalate widens the Rightmove search RADIUS when fewer than 5 listings are found (thin market). This is rental-radius escalation and is unaffected by the PPD geography containment: it does not change a postcode's outcode or sector, so it carries none of the limit-dependence that disabled PPD auto-widening. Response includes thin_market, escalated_from, escalated_to fields when escalation occurs.

Full detail for a single Rightmove listing.

property_id is the numeric Rightmove property ID (the digits at the end of a rightmove.co.uk/properties/... URL), max 12 digits. Full URLs are not accepted. include_images fetches and embeds photos and floorplans as MCP image content. max_images caps the number of property photos (default 3); floorplans always included.

Fetch Rightmove listings for a postcode.

listing_type: "sale" or "rent". sort_by: "newest", "most_reduced", "price_asc", "price_desc". Images are excluded from results.
