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 CF45 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 CF45 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.
