4 Knightsbridge Court, Palmyra Square North, Warrington, WA1 1TA

4 Knightsbridge Court is a one-bedroom mid-terrace house in Warrington (WA1 1TA). It has a recorded floor area of 78 m² (around 837 sq ft), construction records dating it to 1996-2002 and council tax band D. At 78 m² this is the 41st smallest of 47 units on EPC record in the building, where floor areas span 47–116 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 (56 versus a best of 87). The latest certificate (October 2009) shows a D (score 56), a step below the typical UK home. Earlier certificates rated it C (January 2009); the latest reading is one band lower. Between certificates, lighting went from Very Poor to Average; while hot-water efficiency dropped from Average to Very Poor and main heating dropped from Average to Poor. Main heating runs on electricity. The latest certificate is from October 2009, so improvements made since then won't be reflected.

At 78 m² the property is well over the postcode median (59 m² across 46 EPCs), placing it in the larger end of the local stock. On energy efficiency it sits in the bottom 10% of properties in this postcode — significant headroom for improvement. On a £-per-square-foot basis, the last sale (£158/sq ft) was about 15.5% below the postcode norm. Last sold in April 2018, so it's been off the market for around 8 years.
