23 Burwood Avenue, Bromley, BR2 7BH

23 Burwood Avenue is an end-of-terrace house in Bromley (BR2 7BH). It has a recorded floor area of 60 m² (around 646 sq ft), construction records dating it to 1930-1949 and council tax band C. At 60 m² this is the smallest unit on EPC record across the building (60–90 m²). The building's EPC ratings span E to C, with this unit at the bottom. On EPC score it ranks last in the building (47 versus a best of 78). The latest certificate (January 2014) shows an E (score 47), 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, lighting went from Average to Very Good; while main heating dropped from Good to Average. The recommended improvements would lift it to C (score 76), a 2-band jump. The latest certificate is from January 2014, so improvements made since then won't be reflected.

It hasn't traded since June 2007, a hold of 19 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. On energy efficiency it sits in the bottom 10% of properties in this postcode — significant headroom for improvement. Across 1995–2007, sale prices on this property compounded at 11.4% per year. Today's modelled estimate of £313,000 is 49% above the 2007 sale price. On a £-per-square-foot basis, the last sale (£325/sq ft) was about 30.5% above the typical sold price in the postcode.
