Get started20 Ash Hill Close is a three-bedroom semi-detached house in Bushey (WD23 1BW). It has a recorded floor area of 107 m² (around 1152 sq ft), construction records dating it to 1983-1990 and council tax band E. The latest certificate (September 2025) shows a C (score 72). The home occupies a cul-de-sac position.
It hasn't traded since February 2008, a hold of 18 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. Sale prices here have outpaced England HPI: 8.7% per year against 0% for the wider region. Today's modelled estimate of £593,000 sits 90.1% above the 2008 sale of £312,000. On a £-per-square-foot basis, the last sale (£271/sq ft) was about 43% below the postcode norm. At 107 m² the property is well over the postcode median (82 m² across 10 EPCs), placing it in the larger end of the local stock. Its energy rating outperforms most of the postcode (better than 70% of similar EPCs). One planning record on file: an extension approved in 2016.
