Overview

About 18 The Square

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

18 The Square is a one-bedroom end-of-terrace house in Hemel Hempstead (HP1 1ER). It has a recorded floor area of 60 m² (around 646 sq ft), construction records dating it to 1950-1966 and council tax band B. The latest certificate (October 2021) shows a D (score 58), a step below the typical UK home. The rating has held steady at D across 2 certificates since May 2010. Between certificates, roof efficiency dropped from Poor to Very Poor and window efficiency dropped from Good to Average. The recommended improvements would push it to C (score 74). At 60 m² this is the 13th smallest of 16 units on EPC record in the building, where floor areas span 27–63 m². The building's EPC ratings span E to C across 16 units on file. The home occupies a cul-de-sac position.

It hasn't traded since October 1995, a hold of 31 years that's notably long for the area. Only one transfer is on record with HM Land Registry, suggesting it has stayed in the same hands for a long time. At 60 m² the property is well over the postcode median (28 m² across 15 EPCs), placing it in the larger end of the local stock. Today's modelled estimate of £234,000 sits 372.9% above the 1995 sale of £49,485. On a £-per-square-foot basis, the last sale (£77/sq ft) was about 61.4% below the postcode norm.

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 18 The Square is modelled from its 60 m² EPC floor area, its 1 recorded sale and recent sales of comparable homes in HP1 1ER. 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. 1 sale is recorded for 18 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 18 The Square was lodged in October 2021 at band D and is valid until October 2031. 2 certificates are on record, which shows how the home has changed.
Planning records
Planning applications are collected from local authority registers through PlanIt. None is matched to 18 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 14 months, which places each incident at an approximate point. The 32 schools and 30 stops listed are measured in a straight line from HP1 1ER, not by walking route. Road noise is Defra's strategic noise modelling, averaged across the postcode.
Council tax band
18 The Square is in council tax band B. 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.
