SL1 3FX House Prices Overview

SL1 3FX is a postcode-level property market in the SL1 postcode area with 113 registered HM Land Registry sold transactions. The current average sold price is £286,791, compared with a national average of £400,016, which is -28.3% different from the England and Wales benchmark used on UK House Prices. The median sold price is £242,000, with 8 years of observed market activity. A five-year price trend is not shown because the sample is not strong enough for a reliable comparison.

SL1 3FX offers below-average pricing, at 28% below the England and Wales benchmark. The median sits below the average, suggesting that a subset of higher-value sales pulls the mean upward — a pattern common in areas with mixed housing stock ranging from starter homes to luxury properties. Based on 113 registered HM Land Registry transactions across 8 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).

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.
