Overview

About 12a

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

12a is a two-bedroom detached house in St Albans (AL1 1BZ). It has a recorded floor area of 65 m² (around 700 sq ft), construction records dating it to before 1900 and council tax band C. The latest certificate (January 2026) shows a D (score 65), on the cusp of jumping into the C band. When first surveyed in July 2010 the rating was E, the property has climbed 1 band since. Between certificates, wall efficiency went from Very Poor to Good and lighting went from Average to Good; while window efficiency dropped from Poor to Very Poor and hot-water efficiency dropped from Good to Average. The recommended improvements would push it to C (score 80). Main heating runs on electricity. At 65 m² this is the 15th smallest of 31 units on EPC record in the building, where floor areas span 25–161 m². The building's EPC ratings span F to C across 31 units on file.

Today's modelled estimate of £436,000 is 26.4% above the 2015 sale price. On a £-per-square-foot basis, the last sale (£493/sq ft) was about 26.5% above the typical sold price in the postcode. Last sold in May 2015, so it's been off the market for around 11 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 12a is modelled from its 65 m² EPC floor area, its 1 recorded sale and recent sales of comparable homes in AL1 1BZ. 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 12a. 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 12a was lodged in January 2026 at band D and is valid until January 2036. 5 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 12a. 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 30 schools and 30 stops listed are measured in a straight line from AL1 1BZ, not by walking route.
Council tax band
12a 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.
