Nationwide house prices were broadly unchanged month on month in October 2026 after seasonal adjustment, while annual growth slowed to 0.5%, the building society reported on 30 October. Its unadjusted average price was lower than September’s. Those are different measures, and the distinction matters when interpreting headlines about a price fall.
Nationwide house prices: what the October figures say
The October report shows the headline monthly rate rounded to minus 0.0% and describes prices as flat after seasonal effects. The annual measure remains positive. Slower growth means prices are rising less quickly than a year earlier; it is not the same statement as an annual decline.
At the same time, the unadjusted average in the table is £685 below September’s. A reader comparing those two cash figures can correctly observe a lower average without establishing that the seasonally adjusted monthly indicator fell by the same proportion. Mixing the series would make the story less clear.
Why seasonal adjustment changes the comparison
Nationwide’s methodology explanation says its monthly index adjusts for recurring seasonal patterns and for changes in the mix of properties. Its underlying information comes from its own owner-occupier mortgage lending. It tracks a representative property rather than simply taking every asking price currently online.
The government’s UK House Price Index guide explains another important difference: lender indices use mortgage approvals, while the official UK HPI draws on completed transactions. Different sources can describe different stages of the market without one automatically being wrong.
What this means for Brighton and Hove
A UK monthly reading cannot establish what happened to a particular flat in Hove or a terrace in Brighton. Property type, condition, location and the evidence from comparable local transactions still matter. An average figure should not be presented as the price a household can expect to pay or receive.
For someone considering a move, the useful distinction is between the direction of a broad market indicator and the cost of a specific transaction. A purchase budget also depends on the financing available and the property’s costs. The index alone cannot answer either question.
Brighton Locals’ view
Our judgement: the release supports a picture of subdued growth, but a single “prices up” or “prices down” label hides the choice of measure. Readers are better served by seeing the adjusted monthly figure, annual figure and unadjusted cash average together. None supplies a reliable short-term prediction for an individual home.
What to check next
When reading the next report, check the period, geography and whether the figure has been adjusted. Separate asking prices, mortgage approvals and completed sales. Anyone making a transaction should seek current property-specific evidence rather than mechanically applying the national percentage to a listing.
Google Trends’ United Kingdom list for the past 24 hours, observed on 31 October, included a query about a Nationwide property-price drop. That is evidence of search interest in the subject, not evidence that the interpretation contained in the query is correct. It is not a worldwide ranking.
Read the measure before drawing the conclusion: October’s adjusted monthly index was flat, while its unadjusted average was lower.
