23 Eaton Avenue, High Wycombe, HP12 3BP

23 Eaton Avenue is a semi-detached house in High Wycombe (HP12 3BP). It has a recorded floor area of 91 m² (around 980 sq ft), construction records dating it to 1930-1949 and council tax band C. The latest certificate (October 2013) shows an E (score 47), well below the UK norm with real room to improve. The rating has held steady at E across 2 certificates since August 2013. Between certificates, roof efficiency dropped from Good to Poor and hot-water efficiency dropped from Average to Poor. The recommended improvements would lift it to B (score 86), a 3-band jump. The latest certificate is from October 2013, so improvements made since then won't be reflected.

Held since July 2007 — that's 19 years off the open market, well above the local norm. That sale landed at the peak of the pre-credit-crunch market, which is a useful reference point when interpreting the price. Across 1995–2007, sale prices on this property compounded at 10.9% per year. Today's modelled estimate of £369,000 sits 60.4% above the 2007 sale of £230,000. 3 planning records sit against the property, 3 approved, 0 refused. Past consents include an extension, partial demolition, a loft conversion and a conservatory, meaningful when judging how the property has evolved. It lags the bulk of the postcode on energy efficiency (less efficient than 80% of similar EPCs).
