23 Mullen Close, Southampton, SO19 2DR

23 Mullen Close is a three-bedroom detached house in Southampton (SO19 2DR). It has a recorded floor area of 116 m² (around 1249 sq ft), construction records dating it to 2012 onwards and council tax band D. The property has underfloor heating on record, all of which lower running costs and tend to lift resale appeal. The latest certificate (July 2021) shows a C (score 80), near the top of the C band. Earlier certificates rated it B (December 2009); the latest reading is one band lower. Between certificates, wall efficiency went from Good to Very Good and lighting went from Average to Very Good; while window efficiency dropped from Very Good to Good and hot-water efficiency dropped from Very Good to Good. The recommended improvements would push it to B (score 89).

It hasn't traded since January 2001, a hold of 25 years that's notably long for the area. Only one transfer is on record with HM Land Registry, suggesting it has stayed in the same hands for a long time. At 116 m² the property is well over the postcode median (45 m² across 22 EPCs), placing it in the larger end of the local stock. Its energy rating outperforms most of the postcode (better than 82% of similar EPCs). Today's modelled estimate of £366,000 sits 351.3% above the 2001 sale of £81,100. One planning record on file: an extension approved in 2021. Past consents include an extension and a conservatory, meaningful when judging how the property has evolved.
