How this service works
The official UK House Price Index for a postcode's local authority in England or Wales: latest published monthly average price, monthly and annual change, index value, average price by property type and for first-time buyers. Use for area price trends, valuations and market research alongside individual sales data.
Output
Returns a JSON object containing the local authority area name, the reference month of the latest HPI data, the average house price in GBP, percentage monthly and annual price changes, the HPI index value, a breakdown of average prices by property type (detached, semi-detached, terraced, flat), the average price for first-time buyers, the input postcode, and a human-readable summary string. All figures are sourced from the official HM Land Registry UK House Price Index.
Example use cases
Automated property valuation context
“I'm looking at a house in LU6 3BS — what's the current average property price and annual price change for that local authority according to the official UK House Price Index?”
First-time buyer affordability check
“We're first-time buyers considering moving to the BS1 4DJ area. What does the official HPI say about average prices for first-time buyers in that local authority, and how have prices changed this year?”
Investment area comparison
“I'm researching buy-to-let investment and want to compare price growth — can you pull the official UK House Price Index stats for M1 1AE and tell me the monthly and annual change percentages, plus the breakdown by property type?”
Technical details
Endpoint
GEThttps://uk-house-price-index.agent-fee-check.workers.dev/hpi?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need official, government-sourced UK house price statistics at the local authority level derived from a postcode. It is ideal for property valuations, affordability analysis, investment research, and market trend monitoring in England and Wales. Prefer it over scraping property portals (Rightmove, Zoopla) when you need authoritative Land Registry benchmark data rather than asking prices. Not suitable for individual property transaction history (use the Land Registry Price Paid API for that) or for Scottish/Northern Irish properties.
Side effects
- Postcode not found or invalid format — returns error if the postcode cannot be resolved to a local authority
- Postcode outside England or Wales (e.g. Scottish or Northern Irish postcodes) — not covered by this dataset
- HPI data not yet published for the most recent month — may return the previous month's figures
- Local authority with no recent HPI data — some fields such as annual_change_pct or first_time_buyer_gbp may be null
- Payment failure — x402 micropayment not completed, returns 402 status
