9 Grange Road, Harrow, HA1 2PP
About 9 Grange Road
9 Grange Road is a three-bedroom end-of-terrace house in Harrow (HA1 2PP). It has a recorded floor area of 75 m² (around 807 sq ft), construction records dating it to 1930-1949 and council tax band D. The latest certificate (April 2018) shows an E (score 53), well below the UK norm with real room to improve. The recommended improvements would lift it to B (score 88), a 3-band jump. Our model identifies extension potential, subject to local planning policy.
Held since February 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. Across 1997–2007, sale prices on this property compounded at 11.1% per year. Today's modelled estimate of £515,000 sits 106% above the 2007 sale of £249,999. 7 planning records sit against the property, 2 approved, 2 refused. Past consents include an extension, meaningful when judging how the property has evolved. It lags the bulk of the postcode on energy efficiency (less efficient than 88% of similar EPCs).
