19b is a two-bedroom mid-terrace house in Preston (PR1 3TN). It has a recorded floor area of 27 m² (around 291 sq ft), construction records dating it to before 1900 and council tax band A. The latest certificate (September 2014) shows an E (score 49), well below the UK norm with real room to improve. Earlier certificates rated it D (June 2010); the latest reading is one band lower. Between certificates, wall efficiency dropped from Good to Very Poor and hot-water efficiency dropped from Good to Average. The recommended improvements would lift it to C (score 75), a 2-band jump. The latest certificate is from September 2014, so improvements made since then won't be reflected.

It hasn't traded since December 2002, a hold of 23 years that's notably long for the area. At 27 m² it sits well below the postcode median (48 m² across 89 EPCs), making it one of the more compact homes locally. It lags the bulk of the postcode on energy efficiency (less efficient than 75% of similar EPCs). Today's modelled estimate of £138,000 is 25.5% above the 2002 sale price. On a £-per-square-foot basis, the last sale (£378/sq ft) was about 154.4% above the typical sold price in the postcode.
