Overview of the Main UK House Price Indices

The United Kingdom has several major house price indices, each using different datasets and methodologies. Understanding their distinctions helps explain why reported figures may differ slightly between sources.

Land Registry (UK HPI)

The UK House Price Index (HPI) is the official government measure produced by HM Land Registry, the ONS and Land & Property Services. It is based on actual property transactions recorded at completion, making it the most comprehensive and reliable measure — though it is published with a lag of about six to eight weeks.

Halifax House Price Index

The Halifax Index is based on mortgage lending data from Halifax Bank, part of Lloyds Banking Group. It covers mortgaged properties only and reflects prices at the mortgage approval stage. It is one of the oldest and most widely cited private indices, offering good timeliness but a narrower sample than the official HPI.

Nationwide House Price Index

The Nationwide Index is also based on mortgage approvals, using data from Nationwide Building Society. Like Halifax, it excludes cash purchases and may underrepresent high-value properties. However, its consistent methodology and long history make it valuable for understanding trends over time.

Other Indices

Additional indices include:

  • Rightmove — based on asking prices of properties listed on its portal.
  • Zoopla — model-based estimate using listings and sales data.
  • Acadata / E.Surv — combines completion data and valuation information.
  • Hometrack — focuses on urban markets, often used for city-level analysis.
  • RICS — a sentiment-based survey of chartered surveyors, not transactional data.

Summary Comparison

Index Data Source Coverage Lag Strengths Limitations
UK HPI Land Registry transactions All sales (England, Wales, Scotland, NI) ~6–8 weeks Comprehensive and official Slow to publish
Halifax Mortgage approvals (Halifax) UK (mortgaged homes only) ~1 week Fast, consistent, historical data Excludes cash buyers
Nationwide Mortgage approvals (Nationwide) UK (mortgaged homes only) ~1 week Timely and long-running series Sample bias toward Nationwide customers
Rightmove Asking prices Listings on Rightmove Daily Earliest market signal Not sale prices

In summary, the UK HPI provides the most accurate picture of realised sale prices, while the Halifax and Nationwide indices offer early insight into short-term trends. Using them together gives a well-rounded view of the housing market.
