Get started23 Grant Road is a one-bedroom mid-terrace house in Harrow (HA3 7SB). It has a recorded floor area of 46 m² (around 495 sq ft), construction records dating it to 1900-1929 and council tax band C. The latest certificate (December 2019) shows a D (score 66), on the cusp of jumping into the C band. Earlier certificates rated it C (November 2008); the latest reading is one band lower. Between certificates, wall efficiency went from Very Poor to Poor; while window efficiency dropped from Good to Average and main heating dropped from Very Good to Good. The recommended improvements would push it to C (score 76). At 46 m² this is the 4th smallest of 30 units on EPC record in the building, where floor areas span 38–157 m². The building's EPC ratings span G to A across 30 units on file.
It hasn't traded since December 1998, a hold of 27 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. Today's modelled estimate of £258,000 sits 306.3% above the 1998 sale of £63,500. On a £-per-square-foot basis, the last sale (£128/sq ft) was about 50% below the postcode norm. At 46 m² it sits well below the postcode median (71 m² across 29 EPCs), making it one of the more compact homes locally.
23 Grant Road's modelled value sits at over four times its earliest registered sale price (1998).
