Latest sale recorded May 2026. Data refreshed 12 Jul 2026 from HM Land Registry (published with a 1-2 month lag).
How we calculate these figures
Figures use HM Land Registry Price Paid Data, standard sales only (their 'category A' - excludes repossessions, transfers not for value and buy-to-let portfolio deals), and ignore entries under £1,000. England and Wales only; Land Registry publishes with a 1-2 month lag.
- Average price
- The arithmetic mean of every recorded sale on this street, all property types and all years since 1995 combined. Because it spans decades it typically sits below current values - see the year-by-year trend below for the recent level.
- Total sales
- A straight count of the standard sales recorded on this street, with the dates of the first and most recent.
- Lowest / highest sale
- The single lowest and highest individual sale prices recorded on the street in any year - two transactions, not a typical range.
- District trend (% change & chart)
- Calculated across the wider AL7 postcode district, not this street alone (one street rarely has enough sales each year for a reliable trend). We compare the average price in the district's earliest year that had at least 10 recorded sales with its most recent such year.
- Property-type mix
- Share of standard sales by property type across the AL7 district. Any new-build figure compares the average new-build price with the average existing-home price, weighted by number of sales.
- Instant estimate
- An automated estimate from nearby Land Registry sold prices adjusted for market trends - not a formal valuation. A local agent's valuation will be more accurate.
- Change since previous sale
- Where a sale row shows "up/down X% since {year}", that compares the sale price with the most recent earlier recorded sale of the same property - not an area trend.
