Get started89c is a one-bedroom semi-detached house in High Wycombe (HP12 4BS). It has a recorded floor area of 26 m² (around 280 sq ft), construction records dating it to 1991-1995 and council tax band B. The latest certificate (March 2015) shows an E (score 39), well below the UK norm with real room to improve. Earlier certificates rated it D (August 2011); the latest reading is one band lower. Between certificates, lighting went from Very Poor to Very Good; while window efficiency dropped from Good to Average and hot-water efficiency dropped from Average to Very Poor. The recommended improvements would lift it to A (score 98), a 4-band jump. Main heating runs on electricity. The latest certificate is from March 2015, so improvements made since then won't be reflected. Other recorded features include a conservatory. The home occupies a cul-de-sac position.
Sale prices here have outpaced England HPI: 3.6% per year against 0% for the wider region. Today's modelled estimate of £208,000 is 14.3% above the 2021 sale price. On a £-per-square-foot basis, the last sale (£650/sq ft) was about 151.7% above the typical sold price in the postcode. At 26 m² it sits well below the postcode median (72 m² across 49 EPCs), making it one of the more compact homes locally. It lags the bulk of the postcode on energy efficiency (less efficient than 71% of similar EPCs). Sold July 2021 for £182,000. Across the public record there are 4 sales, relatively high churn for a single property. That sale was during the post-pandemic price surge, when transactions cleared materially above pre-2020 trend. One planning record on file: an extension approved in 2008. Past consents include an extension and a conservatory, meaningful when judging how the property has evolved.
