Overview

About 21 Princes Close

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

21 Princes Close is a semi-detached house in Chilton, Aylesbury, Aylesbury (HP18 9LN). It has a recorded floor area of 93 m² (around 1001 sq ft), construction records dating it to 1950-1966 and council tax band C. The latest certificate (March 2016) shows an E (score 44), well below the UK norm with real room to improve. The recommended improvements would lift it to C (score 79), a 2-band jump. Main heating runs on oil. The latest certificate is from March 2016, so improvements made since then won't be reflected.

Across 2016–2017, sale prices on this property compounded at -96.6% per year. Today's modelled estimate of £536,000 sits 5855.6% above the 2017 sale of £9,000. On a £-per-square-foot basis, the last sale (£9/sq ft) was about 97% below the postcode norm. One planning record on file: an extension approved in 2017. Past consents include an extension, meaningful when judging how the property has evolved. At 93 m² it's 19.2% larger than the typical home in the postcode (78 m² median across 19 EPCs). It lags the bulk of the postcode on energy efficiency (less efficient than 84% of similar EPCs). Last sold in July 2017, so it's been off the market for around 9 years.

Method

How to read this page

Where every figure above comes from, how current it is and what it can't tell you.
Valuation method in detail
How the estimate is made
The estimate for 21 Princes Close is modelled from its 93 m² EPC floor area, its 2 recorded sales and recent sales of comparable homes in HP18 9LN. 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. 2 sales are recorded for 21 Princes Close. 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 21 Princes Close was lodged in March 2016 at band E and expired in March 2026, 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. 1 application is matched to 21 Princes Close. 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 12 months, which places each incident at an approximate point. The 1 school and 12 stops listed are measured in a straight line from HP18 9LN, not by walking route. Road noise is Defra's strategic noise modelling, averaged across the postcode.
Council tax band
21 Princes Close is in council tax band C. 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.
