20 Aldwick Court, Cell Barnes Lane, St Albans, AL1 5QG

20 Aldwick Court is a two-bedroom end-of-terrace house in St Albans (AL1 5QG). It has a recorded floor area of 58 m² (around 624 sq ft), construction records dating it to 1950-1966 and council tax band C. At 58 m² this is the 2nd smallest of 35 units on EPC record in the building, where floor areas span 55–65 m². The building's EPC ratings span D to C, with this unit at the bottom. On EPC score it ranks last in the building (68 versus a best of 80). The latest certificate (February 2019) shows a D (score 68), on the cusp of jumping into the C band. The recommended improvements would push it to C (score 78).

It hasn't traded since April 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. On energy efficiency it sits in the bottom 10% of properties in this postcode — significant headroom for improvement. Today's modelled estimate of £282,000 sits 116.9% above the 2007 sale of £130,000.
