Get started21a is an end-of-terrace house in High Wycombe (HP12 3AX). It has a recorded floor area of 66 m² (around 710 sq ft), construction records dating it to 1900-1929 and council tax band B. The latest certificate (December 2013) shows an E (score 43), well below the UK norm with real room to improve. Earlier certificates rated it D (August 2013); the latest reading is one band lower. Between certificates, wall efficiency dropped from Average to Poor and roof efficiency dropped from Average to Very Poor. The recommended improvements would push it to D (score 56). The latest certificate is from December 2013, so improvements made since then won't be reflected. At 66 m² this is the 7th smallest of 29 units on EPC record in the building, where floor areas span 37–105 m². The building's EPC ratings span F to C across 29 units on file.
It hasn't traded since November 1998, a hold of 27 years that's notably long for the area. Only one transfer is on record with HM Land Registry, suggesting it has stayed in the same hands for a long time. Today's modelled estimate of £216,000 sits 260% above the 1998 sale of £60,000. On a £-per-square-foot basis, the last sale (£84/sq ft) was about 51.3% below the postcode norm. 2 planning records sit against the property, 2 approved, 0 refused. Past consents include an extension, meaningful when judging how the property has evolved. At 66 m² it's 15.9% smaller than the typical home in the postcode (79 m² median across 28 EPCs). It lags the bulk of the postcode on energy efficiency (less efficient than 79% of similar EPCs).
21a's EPC is over a decade old — improvements since won't be reflected.
