About 21b
A plain-English summary derived from public records, EPC certificates, sold prices and local data.
21b is a two-bedroom semi-detached house in Aylesbury (HP21 8BN). It has a recorded floor area of 40 m² (around 431 sq ft), construction records dating it to 1967-1975 and council tax band A. At 40 m² this is the smallest unit on EPC record across the building (40–179 m²). The building's EPC ratings span E to C, with this unit at the bottom. The latest certificate (July 2012) shows an E (score 50), well below the UK norm with real room to improve. The recommended improvements would lift it to C (score 72), a 2-band jump. Main heating runs on electricity. The latest certificate is from July 2012, so improvements made since then won't be reflected.
At 40 m² it sits well below the postcode median (69 m² across 17 EPCs), making it one of the more compact homes locally. It lags the bulk of the postcode on energy efficiency (less efficient than 76% of similar EPCs). Last changed hands 10 years ago, in April 2016. Across the public record there are 4 sales, relatively high churn for a single property. Across 1999–2016, sale prices on this property compounded at 5.8% per year. Today's modelled estimate of £151,000 is 37.3% above the 2016 sale price. On a £-per-square-foot basis, the last sale (£255/sq ft) was about 33.8% above the typical sold price in the postcode.

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 21b is modelled from its 40 m² EPC floor area, its 4 recorded sales and recent sales of comparable homes in HP21 8BN. 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. 4 sales are recorded for 21b. 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 21b was lodged in July 2012 at band E and expired in July 2022, 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 21b. 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 15 months, which places each incident at an approximate point. The 26 schools and 30 stops listed are measured in a straight line from HP21 8BN, not by walking route. Road noise is Defra's strategic noise modelling, averaged across the postcode.
- Council tax band
- 21b is in council tax band A. 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.
