Overview

About 623 London Road

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

623 London Road is a four-bedroom semi-detached house in Isleworth (TW7 4ER). It has a recorded floor area of 115 m² (around 1238 sq ft), construction records dating it to 1930-1949 and council tax band F. The latest certificate (October 2013) shows a D (score 59), a step below the typical UK home. When first surveyed in March 2012 the rating was F, the property has climbed 2 bands since. Between certificates, roof efficiency went from Poor to Average, window efficiency went from Poor to Good and hot-water efficiency went from Poor to Good; while lighting dropped from Very Good to Poor. The recommended improvements would lift it to B (score 83), a 2-band jump. The latest certificate is from October 2013, so improvements made since then won't be reflected. Our model identifies extension potential, subject to local planning policy.

On the market in November 2014 and unlisted since — roughly 12 years. Across the public record there are 4 sales, relatively high churn for a single property. 2 planning records sit against the property, 1 approved, 0 refused. Past consents include an extension, meaningful when judging how the property has evolved. At 115 m² it's 17.3% larger than the typical home in the postcode (98 m² median across 7 EPCs). Across 2002–2014, sale prices on this property compounded at 6.4% per year. Today's modelled estimate of £692,000 is 42.7% above the 2014 sale price.
