About 11a
A plain-English summary derived from public records, EPC certificates, sold prices and local data.

At 66 m² this is the 3rd smallest of 19 units on EPC record in the building, where floor areas span 66–156 m². The building's EPC ratings span F to C, with this unit at the top. Period features are noted in the property record. The latest certificate (November 2011) shows a C (score 69), just inside the C band. The latest certificate is from November 2011, so improvements made since then won't be reflected.

At 66 m² it's 18.2% smaller than the typical home in the postcode (81 m² median across 18 EPCs). Sold April 2021 for £198,000.

Start your researchHow to read this page
Where every figure above comes from, how current it is and what it can't tell you.
- How the estimate is made
- The estimate for 11a is modelled from its 66 m² EPC floor area, its 6 recorded sales and recent sales of comparable homes in CF23 6HE. 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.
- Where sold prices come from
- Sold prices are HM Land Registry Price Paid Data, which covers residential sales in England and Wales since 1995. 6 sales are recorded for 11a. Sales normally appear two to three months after completion, so the most recent ones take time to show up anywhere.
- Reading the EPC
- Energy Performance Certificates rate homes from A (most efficient) to G and last 10 years. The latest one for 11a was lodged in November 2011 at band C and expired in November 2021, so a new one is needed to sell or let. Floor area, heating and insulation details on this page come from it.
- Planning records
- Planning applications are collected from local authority registers through PlanIt. None is matched to 11a. Councils sometimes file applications under a different address format, and applications on neighbouring land aren't listed here; the report covers both.
- Area figures
- Crime is police-recorded street-level data over the last 18 months, which places each incident at an approximate point. Schools and stops are measured in a straight line from CF23 6HE.
- Council tax band
- 11a is in council tax band D. Bands are set by the Valuation Office Agency from historic values (1 April 1991 in England, 1 April 2003 in Wales), not today's price; the amount you pay depends on the council's rate for the band.
