Flat 2, 17 Knowsley Road, Southport, PR9 0BN

Flat 2 is a semi-detached house in Southport (PR9 0BN). It has a recorded floor area of 55 m² (around 592 sq ft), construction records dating it to before 1900 and council tax band A. The latest certificate (March 2014) shows a D (score 56), a step below the typical UK home. The rating has held steady at D across 2 certificates since March 2014. Between certificates, wall efficiency dropped from Good to Very Poor. The recommended improvements would push it to C (score 76). The latest certificate is from March 2014, so improvements made since then won't be reflected. At 55 m² this is the 7th smallest of 8 units on EPC record in the building, where floor areas span 41–56 m². The building's EPC ratings span E to C across 8 units on file.

It hasn't traded since January 2008, a hold of 18 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. At 55 m² the property is well over the postcode median (41 m² across 7 EPCs), placing it in the larger end of the local stock. Today's modelled estimate of £118,000 is 12.4% above the 2008 sale price. On a £-per-square-foot basis, the last sale (£177/sq ft) was about 16.8% below the postcode norm.
