Flat 1, 128 West Wycombe Road, High Wycombe, HP12 3AA
About Flat 1
Flat 1 is a semi-detached house in High Wycombe (HP12 3AA). It has a recorded floor area of 36 m² (around 388 sq ft), construction records dating it to 1900-1929 and council tax band B. At 36 m² this is the smallest unit on EPC record across the building (36–43 m²). The latest certificate (May 2026) shows a C (score 74). When first surveyed in April 2016 the rating was D, the property has climbed 1 band since. Between certificates, wall efficiency went from Very Poor to Good and lighting went from Very Poor to Good. This certificate was lodged in the last six months, so the rating reflects current condition.
Today's modelled estimate of £158,000 is 75.7% below the 2016 sale of £650,000, an unusual pattern given regional price growth and worth checking against the EPC condition. On a £-per-square-foot basis, the last sale (£1,677/sq ft) was about 733.8% above the typical sold price in the postcode. 2 planning records sit against the property, 1 approved, 1 refused. Past consents include an extension, meaningful when judging how the property has evolved. Last changed hands 10 years ago, in October 2016. At 36 m² it's 21.7% smaller than the typical home in the postcode (46 m² median across 69 EPCs).
