9 Carnarvon Avenue, Grimsby, DN34 5BS

9 Carnarvon Avenue is a three-bedroom detached house in Grimsby (DN34 5BS). It has a recorded floor area of 62 m² (around 667 sq ft), construction records dating it to 1930-1949 and council tax band C. The latest certificate (April 2013) shows an F (score 32), near the bottom of the EPC scale. Earlier certificates rated it E (May 2009); the latest reading is one band lower. Between certificates, roof efficiency dropped from Average to Poor and main heating dropped from Good to Average. The recommended improvements would lift it to C (score 73), a 3-band jump. Main heating runs on lpg. The latest certificate is from April 2013, so improvements made since then won't be reflected.

It hasn't traded since November 2009, a hold of 17 years that's notably long for the area. That sale fell during the post-crash dip, which often skews comparisons against later neighbouring sales. At 62 m² it sits well below the postcode median (93 m² across 4 EPCs), making it one of the more compact homes locally. On energy efficiency it sits in the bottom 10% of properties in this postcode — significant headroom for improvement. Today's modelled estimate of £179,000 is 40.9% above the 2009 sale price. On a £-per-square-foot basis, the last sale (£190/sq ft) was about 114% above the typical sold price in the postcode.
