Flat 3, 13 Abercorn Crescent, Harrow, HA2 0PX

Flat 3 is a one-bedroom semi-detached house in Harrow (HA2 0PX). It has a recorded floor area of 37 m² (around 398 sq ft), construction records dating it to 1930-1949 and council tax band C. The latest certificate (February 2017) shows an E (score 48), well below the UK norm with real room to improve. Earlier certificates rated it D (July 2010); the latest reading is one band lower. Between certificates, roof efficiency dropped from Average to Very Poor and window efficiency dropped from Good to Average. The recommended improvements would push it to D (score 64). Records show the property has been extended at some point in its history.

It hasn't traded since November 2007, a hold of 19 years that's notably long for the area. That sale landed at the peak of the pre-credit-crunch market, which is a useful reference point when interpreting the price. Across 2002–2007, sale prices on this property compounded at 21.4% per year. Today's modelled estimate of £231,000 sits 56.1% above the 2007 sale of £148,000. On a £-per-square-foot basis, the last sale (£372/sq ft) was about 34.7% above the typical sold price in the postcode. At 37 m² it sits well below the postcode median (78 m² across 28 EPCs), making it one of the more compact homes locally. It lags the bulk of the postcode on energy efficiency (less efficient than 82% of similar EPCs). One planning record on file: a loft conversion approved in 2022. Past consents include a loft conversion, meaningful when judging how the property has evolved.
