Get started1 Arnold Close is a three-bedroom semi-detached house in Harrow (HA3 9TN). It has a recorded floor area of 122 m² (around 1313 sq ft), construction records dating it to 1983-1990 and council tax band D. The latest certificate (February 2026) shows a C (score 74).

Held since October 2007 — that's 19 years off the open market, well above the local norm. That sale landed at the peak of the pre-credit-crunch market, which is a useful reference point when interpreting the price. At 122 m² the property is well over the postcode median (64 m² across 11 EPCs), placing it in the larger end of the local stock. Today's modelled estimate of £532,000 sits 65.2% above the 2007 sale of £322,000.
The EPC has just been inspected, so the rating reflects current condition.
