Sold house prices in SM1 have an overall average of £392,759, based on all 7,587 residential sales on record — drawn from every recorded UK house sale.
Medians over the most recent 12 months of all UK property sales (to July 2026). Median is used, not mean — it isn't skewed by the odd very-high sale.
Across SM1, the median sold price over the 12 months to July 2026 was £440,000 — it rose 3.5% on the year before. That reflects 434 recorded sales. Detached homes are the priciest at a median of £587,500, while flat/maisonette homes are the most affordable at £275,000. Over the past year, other homes moved the most (+45.6%). Within SM1, the SM1 1 sector saw the strongest recent growth (+2%) and SM1 3 the softest (-9%).
New-build homes were 0% of recent sales, a share that is steady.
These figures track the median of prices actually paid, not a like-for-like index. A move can reflect a change in what sold — more new homes, or a different mix of house types and sizes — as much as any change in what a given home is worth.

Year-on-year change in the median sold price; green = up, red = down. Final column is the latest-year median.
New-build homes were 0% of sales in the latest year, and the share is ▬ steady over the period — a marker of how much new housing is being built here (not a price forecast). See the new-build chart above.
How these figures are calculated. Year-on-year change compares the median sold price over the most recent 12 months of data with the 12 months before it. We use the median, not the average, so a few unusually high or low sales don't distort it. Because HM Land Registry data lags — sales take time to be registered — the most recent month or two are provisional and tend to revise upward. Figures track the mix of what actually sold, so they are not a like-for-like index. The same method is used across this site, so an area's figure here matches its ranking in investment trends.
