SN15 3YY House Prices Overview

SN15 3YY is a postcode-level property market in the SN15 postcode area with 81 registered HM Land Registry sold transactions. The current average sold price is £166,183, compared with a national average of £398,894, which is -58.3% different from the England and Wales benchmark used on UK House Prices. The median sold price is £164,950, with 21 years of observed market activity. A five-year price trend is not shown because the sample is not strong enough for a reliable comparison.

SN15 3YY is a more affordable market, with average prices 58% below the national average. The close alignment of median and average prices indicates a relatively uniform market without extreme high-value outliers. Based on 81 registered HM Land Registry transactions across 21 years of data, these figures reflect actual completed sales rather than asking prices. Five-year growth compares average prices over 12-month windows; the most recent months may be slightly incomplete due to registration lag (sales can take 2–6 months to appear in the Land Registry). Note that this analysis draws on 81 transactions, which gives a directional picture but may not capture the full price range of this area.

Frequently Asked Questions

Why is my postcode missing?

A postcode may be missing when it has no recorded sales or too few registered HM Land Registry transactions to publish a useful page. Very recent completions can also be absent until registration and the next monthly data refresh.

How is the average price for this postcode calculated?

The average is the mean of registered residential sale prices available for this postcode in the Land Registry data. It is based on sold prices, not current valuations.

Are these asking prices?

No. These are completed sold prices recorded by HM Land Registry. They are not estate-agent asking prices, live listings or automated valuations.

Can I use this as a valuation?

No. The page is a research summary of historical sold prices. Use it to understand local evidence, then compare property condition, size, tenure, transaction type and professional valuation advice before making a decision.

Why can small postcode samples look unusual?

Some postcodes have only a small number of recorded sales. A few high or low value transactions can move the average, so the transaction count should be read alongside the price.
