About 15 Westbury Street
15 Westbury Street is a six-bedroom mid-terrace house in Swansea (SA1 4JN). It has a recorded floor area of 137 m² (around 1475 sq ft), construction records dating it to 1900-1929 and council tax band D. The latest certificate (August 2019) shows an E (score 49), well below the UK norm with real room to improve. The rating has held steady at E across 3 certificates since October 2008. Between certificates, lighting went from Good to Very Good. The recommended improvements would lift it to C (score 78), a 2-band jump.
It hasn't traded since May 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. It lags the bulk of the postcode on energy efficiency (less efficient than 74% of similar EPCs). Today's modelled estimate of £191,000 is 41.5% above the 2009 sale price.
