Your note and figure are shown publicly on this page.
The estimate for 20 Back Street is modelled from its 117 m² EPC floor area, the absence of a recorded sale and recent sales of comparable homes in PE31 6TU. It is an automated estimate, not a survey or mortgage valuation: condition, layout and improvements that aren't on record can move the real figure either way.

20 Back Street has no Land Registry sales on file, suggesting it has stayed in the same hands since registration began.
That can mean the property has never traded since the registry began publishing in 1995, was a new build that hasn't been registered yet, or is held in the same hands long-term.
Median price across the last 5 sales in PE31 6TU: £255,000 (2026–2019).
