23 Heol Bryncelyn, Dafen, Llanelli, SA14 8WE

23 Heol Bryncelyn is a three-bedroom semi-detached house in Dafen, Llanelli, Llanelli (SA14 8WE). It has a recorded floor area of 106 m² (around 1141 sq ft), construction records dating it to 1967-1975 and council tax band C. The latest certificate (November 2014) shows an E (score 49), well below the UK norm with real room to improve. Earlier certificates rated it C (May 2009); the latest reading is 2 bands lower. Between certificates, window efficiency went from Average to Good; while wall efficiency dropped from Good to Poor and roof efficiency dropped from Good to Very Poor. The recommended improvements would lift it to C (score 80), a 2-band jump. The latest certificate is from November 2014, so improvements made since then won't be reflected. The home occupies a cul-de-sac position.

It hasn't traded since September 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 106 m² the property is well over the postcode median (79 m² across 12 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. Across 1998–2009, sale prices on this property compounded at 7% per year. Today's modelled estimate of £166,000 is 40.7% above the 2009 sale price. On a £-per-square-foot basis, the last sale (£103/sq ft) was about 17.3% above the typical sold price in the postcode.
