Apartment 3 is a two-bedroom end-of-terrace house in Wellingborough (NN8 1ED). It has a recorded floor area of 109 m² (around 1173 sq ft), construction records dating it to 2007 onwards and council tax band C. At 109 m² this is the largest unit on EPC record across the building (52–109 m²). The building's EPC ratings span C to B, with this unit at the top. On EPC score it ranks first in the building (81 versus a worst of 70). The property has underfloor heating on record, all of which lower running costs and tend to lift resale appeal. The latest certificate (July 2019) returns a B (score 81), comfortably above the UK average. The rating has held steady at B across 3 certificates since March 2009. Between certificates, main heating went from Average to Good.

It hasn't traded since November 2009, a hold of 17 years that's notably long for the area. That sale fell during the post-crash dip, which often skews comparisons against later neighbouring sales. At 109 m² the property is well over the postcode median (55 m² across 10 EPCs), placing it in the larger end of the local stock. On energy efficiency it sits in the top 10% of properties in this postcode. Today's modelled estimate of £214,000 is 45.6% above the 2009 sale price.
