11 Broad Green is a three-bedroom mid-terrace house in Southampton (SO14 1LF). It has a recorded floor area of 93 m² (around 1001 sq ft), construction records dating it to 1930-1949 and council tax band B. The latest certificate (March 2016) shows a G (score 12), near the bottom of the EPC scale. Earlier certificates rated it D (April 2009); the latest reading is 3 bands lower. Between certificates, lighting went from Average to Good; while wall efficiency dropped from Poor to Very Poor and window efficiency dropped from Average to Very Poor. The recommended improvements would lift it to B (score 88), a 5-band jump. Main heating runs on to be used only when there is no heating/hot. The latest certificate is from March 2016, so improvements made since then won't be reflected.

Held since July 2009 — that's 17 years off the open market, well above the local norm. That sale fell during the post-crash dip, which often skews comparisons against later neighbouring sales. On energy efficiency it sits in the bottom 10% of properties in this postcode — significant headroom for improvement. Today's modelled estimate of £210,000 is 32.9% above the 2009 sale price.
