Overview

About 5 The Square

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

5 The Square is a two-bedroom mid-terrace house in Brill, Aylesbury, Aylesbury (HP18 9RP). It has a recorded floor area of 72 m² (around 775 sq ft), construction records dating it to before 1900 and council tax band D. The latest certificate (July 2026) shows an F (score 33), near the bottom of the EPC scale. Earlier certificates rated it E (June 2009); the latest reading is one band lower. Between certificates, wall efficiency went from Very Poor to Poor, roof efficiency went from Very Poor to Average and lighting went from Good to Very Good; while hot-water efficiency dropped from Average to Very Poor and main heating dropped from Average to Very Poor. The recommended improvements would lift it to C (score 74), a 3-band jump. Main heating runs on electricity. This certificate was lodged in the last six months, so the rating reflects current condition. Other recorded features include a conservatory.

Sold December 2019 for £340,000. Across the public record there are 4 sales, relatively high churn for a single property. 2 planning records sit against the property, 1 approved, 0 refused. Past consents include an extension and a conservatory, meaningful when judging how the property has evolved.

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 5 The Square is modelled from its 72 m² EPC floor area, its 4 recorded sales and recent sales of comparable homes in HP18 9RP. 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 5 The Square. 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 5 The Square was lodged in July 2026 at band F and is valid until July 2036. 3 certificates are on record, which shows how the home has changed.
Planning records
Planning applications are collected from local authority registers through PlanIt. 2 applications are matched to 5 The Square. 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 2 schools and 9 stops listed are measured in a straight line from HP18 9RP, not by walking route. Road noise is Defra's strategic noise modelling, averaged across the postcode.
Council tax band
5 The Square 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.
