11a, Grendon Avenue, Oldham, OL8 4HT
About 11a
11a is an end-of-terrace house in Oldham (OL8 4HT). It has a recorded floor area of 127 m² (around 1367 sq ft), construction records dating it to 1900-1929 and council tax band B. The latest certificate (April 2016) shows an E (score 51), well below the UK norm with real room to improve. The rating has held steady at E across 6 certificates since August 2013. Between certificates, wall efficiency went from Very Poor to Good, roof efficiency went from Very Poor to Good and lighting went from Good to Very Good; while window efficiency dropped from Good to Average and hot-water efficiency dropped from Good to Very Poor. The recommended improvements would lift it to C (score 75), a 2-band jump. Main heating runs on electricity. The latest certificate is from April 2016, so improvements made since then won't be reflected.
Untraded for 28 years, with the last transfer in November 1998. 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 £189,000 sits 372.5% above the 1998 sale of £40,000. On a £-per-square-foot basis, the last sale (£29/sq ft) was about 26.3% below the postcode norm.
