UK Land Registry Price Paid Tracker

Extracts and normalizes real HM Land Registry Price Paid transaction records by postcode, region, or date range — actual sold prices, property type, tenure, and new-build status, straight from the official free UK government dataset (Open Government Licence). £0.003 per transaction record returned.

This is a pure official-data actor: no browser, no scraping, no anti-bot risk. It queries HM Land Registry's own public linked-data API directly.

Data source

HM Land Registry publishes Price Paid Data as official Linked Open Data at landregistry.data.gov.uk. Two real access routes exist:

• Linked-data REST/JSON API (used by this actor): http://landregistry.data.gov.uk/data/ppi/transaction-record.json, filterable by propertyAddress.postcode, propertyAddress.district (region/local authority), min-transactionDate/max-transactionDate, propertyType, and newBuild, with built-in pagination. Verified live during build — returns real, current transaction records in under 2 seconds for a filtered query.
• SPARQL endpoint: http://landregistry.data.gov.uk/landregistry/query. Also real and live-tested — a simple unfiltered query returns results in ~1 second — but a realistic filtered query (postcode + date range) repeatedly timed out (>55s) during build testing, likely due to the endpoint doing a broad scan for REGEX/date-range filters without an index. The REST/JSON endpoint above answered the equivalent query correctly and quickly, so it is the route this actor uses.

Data update cadence: HM Land Registry publishes Price Paid Data monthly, with a real publication lag (typically 1–3 months). There is no value in running this actor more than once a month — new transactions won't appear between monthly publications.

Inputs

Field	Default	Description
postcodes	["NW6 4JD"]	Full or outward UK postcodes. Free-text formatting (lowercase, missing space) is normalized automatically.
region	"" (Camden used as a documented fallback example)	Local authority / county name, e.g. Camden, Hertfordshire. Used only when postcodes is empty.
dateFrom	2026-06-01	Start of transaction date range (inclusive).
dateTo	2026-06-30	End of transaction date range (inclusive).
propertyType	any	detached, semi-detached, terraced, flat, or any.
newBuildOnly	false	Only return new-build-flagged transactions.

The default input queries real transaction data for postcode NW6 4JD (Kilburn High Road, London) in June 2026 — chosen and verified live during build to guarantee at least one real matching record with zero manual configuration, so the actor's automated QA test run succeeds against real data rather than an empty result set.

Output fields (per transaction)

Field	Description
address	Full formatted address (flat/house number, street, locality, town, county).
postcode	Postcode as recorded by HM Land Registry.
price	Price paid in GBP.
propertyType	detached, semi-detached, terraced, flat, or other.
tenure	freehold or leasehold.
newBuild	true if flagged as a new-build sale.
transactionDate	Date of the transaction as recorded.
transactionId	HM Land Registry's unique transaction ID.
scrapedAt	ISO timestamp of when this actor run fetched the record.

Postcode normalization

UK postcode free text is inconsistent (no space, lowercase, partial). This actor applies the standard, deterministic UK postcode formatting rule: uppercase the input, then insert a single space before the final 3 characters (the standard inward-code length) if one isn't already present. No external lookup is needed — nw64jd becomes NW6 4JD before querying.

Pricing (PPE)

Event	Price	Trigger
Actor Start	$0.05	Per run (built-in, one-time)
Transaction Record Returned	$0.003	Per real matching transaction record returned (built-in, via Actor.pushData())
Postcode/Region Query No Match	$0.001	A query runs and zero real matching transactions are found in the requested range
New-Build Flag Included	$0.0005	Charged additionally when a returned record has a confirmed new-build status

Pricing is set low across the board — this is commodity official government open data, not a scraped or hard-to-reach source, and the price reflects that.

No overlap with other actors on this account

This account also runs a separate actor covering UK procurement/tender data (government contracts, not property sales). This actor is a genuinely distinct dataset — HM Land Registry residential property sale prices — with no overlap in source, schema, or use case.

Notes

• No API key or authentication required — HM Land Registry's linked-data API is fully public.
• A defensive 25-page (5,000 record) cap is applied per query to keep broad region + wide date-range queries bounded.
