September Cottage is a three-bedroom detached house in Mayfield (TN20 6DD). It has a recorded floor area of 118 m² (around 1270 sq ft), construction records dating it to before 1900 and council tax band E. The latest certificate (April 2016) shows an E (score 51), well below the UK norm with real room to improve. Earlier certificates rated it D (October 2011); the latest reading is one band lower. Between certificates, roof efficiency went from Very Poor to Average; while window efficiency dropped from Average to Poor. The recommended improvements would lift it to C (score 74), a 2-band jump. The latest certificate is from April 2016, so improvements made since then won't be reflected. Other recorded features include a conservatory. Period features are noted in the property record.
It hasn't traded since May 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.
