The UK housing market is often described as confusing, and for good reason. One article will tell you that prices are rising this month while another article will tell you that they are falling. One news will say that there’s nothing to worry about while another piece will say that everything is falling apart.
But why? It’s because different sources rely on different house price indices, which measure different segments of the market. The data isn’t wrong, they’re just looking at different things and coming to different conclusions.
So, to get a complete sense of what’s happening with UK house prices, it’s worth looking at the five main property indices – Zoopla, Halifax, Rightmove, Nationwide and HM Land Registry - together.
Why UK House Price Indices Often Disagree
The biggest mistake most people make is assuming there is one “official” monthly house price figure. There isn’t.
Some indices track asking prices, some track mortgage approvals, and others track completed sales. These differences create lags and distortions. For example, sellers may reduce asking prices quickly, while actual sale prices take months to reflect that change.
This is why indices often appear to contradict each other.
Zoopla House Price Index: The Demand Indicator
Zoopla’s index is one of the more sophisticated measures in the UK market because it blends multiple data sources, including:
- Asking prices
- Mortgage valuation data
- Agreed sales activity
- Historical sold-price modelling
This makes Zoopla more of a hybrid demand-and-valuation index rather than a simple sentiment tracker.
Zoopla’s House Price Index for March 2026 showed that the average UK house price had risen by 1.3% compared with last year and had reached £270,500.
Rightmove House Price Index: Seller Expectations
Rightmove tracks the asking prices of newly listed properties, making it the earliest indicator of pricing behaviour in the market. It is important to understand one key limitation though. It measures what sellers are asking, not what buyers are paying.
Because of this, Rightmove is highly sensitive to sentiment shifts. If sellers become more confident, asking prices rise quickly. If uncertainty increases, new listings tend to come to market at lower or more competitive prices.
According to Rightmove, the average UK property asking price was £371,042 in March 2026.
Halifax House Price Index: Mortgage Market Reality
The Halifax index is based on mortgage lending data from one of the UK’s largest lenders. It reflects actual purchase prices, but only for properties financed through Halifax mortgages. This makes it a strong indicator of mainstream buyer activity, particularly in the residential market.
However, it does not include cash buyers and non-Halifax mortgage lenders. As a result, it only represents a partial, albeit highly relevant, view of mortgage-driven demand.
Halifax data shows that the average UK house price fell by 0.5% between February and March 2026 and reached £299,677.
Nationwide House Price Index: Long-Term Mortgage Trends
The Nationwide index is based on mortgage lending data from Nationwide Building Society. Crucially, this means:
- It is lender-specific (Nationwide only)
- It is building society-based dataset
- It is statistically adjusted to estimate broader UK house price movements
Because Nationwide has a large and geographically diverse mortgage book, its data is used as a proxy for national housing trends, despite not covering the entire market. Like Halifax, it excludes cash buyers, meaning it reflects only mortgage-financed transactions.
Nationwide’s data reveals that house prices rose by 0.9% in the month to March and reached £277,186.
HM Land Registry House Price Index: Official Record
The HM Land Registry is widely regarded as the most comprehensive and authoritative measure of UK house prices because it is based on actual completed property transactions across England and Wales, and covers both cash purchases and mortgage-financed sales.
This makes it the closest reflection of true market selling prices rather than expectations or estimates. However, its strength in accuracy comes with a natural delay, as it depends on the full completion of a sale, the legal registration of the transaction, and subsequent data processing and validation.
As a result, while it remains the definitive benchmark for measuring actual house price inflation in 2026, it is not a real-time indicator of current market conditions. The latest data available from this index is for January 2026.
How the 5 UK House Price Indices Compare
Index | Latest Publicly Released Property Price |
|---|---|
Zoopla | £270,500 |
Rightmove | £371,042 |
Halifax | £299,677 |
Nationwide | £277,186 |
HM Land Registry | £268,421 (January) |
What These Indices Tell Us Together
When viewed in isolation, each index can tell a slightly different story. But when combined, they give a holistic picture of the housing market.
First, asking price indices show how sellers and buyers are feeling. Then, lender-based indices confirm whether those expectations translate into actual transactions. Finally, HM Land Registry validates everything with completed sales data.
This layered structure explains why the UK housing market often appears contradictory in the short term but consistent over the long term.
Conclusion
UK house prices are not captured by a single figure, but by a set of overlapping signals that move at different speeds. From early sentiment in asking prices to mortgage-backed transaction data and finally confirmed sales records, each index reflects a different stage of the same housing cycle.
Once you understand this timing gap, the apparent contradictions between indices start to make sense. Rather than relying on any one measure in isolation, the real insight comes from reading them together.
FAQs
UK house price indices differ because they measure different stages of the property market. Some track asking prices, others track mortgage lending, and others use completed sales. These differences naturally lead to variations in reported price trends.
The HM Land Registry UK House Price Index is considered the most accurate because it is based on completed property transactions, including both cash and mortgage purchases. However, it is also the slowest to reflect market changes.
Rightmove reflects new asking prices when properties first come to market, showing seller expectations. Zoopla, on the other hand, uses a mix of asking prices, demand data, and valuation models, making it a broader indicator of market momentum.
No. Both the Halifax House Price Index and the Nationwide House Price Index are based on mortgage lending data only, meaning they exclude cash purchases and reflect only mortgage-financed transactions.
The HM Land Registry index is delayed because it relies on fully completed sales, legal registration, and data validation before publication. This process ensures high accuracy but means the data typically reflects market conditions from one to three months earlier.
