Apartment 2, 18 Knight Street, Liverpool, L1 9DS

Apartment 2 is a three-bedroom semi-detached house in Liverpool (L1 9DS). It has a recorded floor area of 92 m² (around 990 sq ft), construction records dating it to 1996-2002 and council tax band D. At 92 m² this is the 7th smallest of 9 units on EPC record in the building, where floor areas span 57–95 m². The building's EPC ratings span D to B, with this unit at the bottom. On EPC score it ranks last in the building (66 versus a best of 82). The latest certificate (September 2021) shows a D (score 66), on the cusp of jumping into the C band. Earlier certificates rated it C (October 2011); the latest reading is one band lower. Between certificates, hot-water efficiency went from Very Poor to Poor and main heating went from Very Poor to Poor; while window efficiency dropped from Good to Average. The recommended improvements would push it to C (score 71). Main heating runs on electricity.

It hasn't traded since December 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. It lags the bulk of the postcode on energy efficiency (less efficient than 85% of similar EPCs). Today's modelled estimate of £399,000 is 19.8% above the 2007 sale price.
