About 17 Heol Plas Isaf
17 Heol Plas Isaf is a two-bedroom semi-detached house in Llangennech, Llanelli, Llanelli (SA14 8TJ). It has a recorded floor area of 63 m² (around 678 sq ft), construction records dating it to 1976-1982 and council tax band C. The latest certificate (April 2014) shows a D (score 56), a step below the typical UK home. The rating has held steady at D across 2 certificates since January 2009. Between certificates, window efficiency went from Average to Good, lighting went from Very Poor to Poor and main heating went from Average to Good; while hot-water efficiency dropped from Average to Poor. The recommended improvements would lift it to B (score 91), a 2-band jump. The latest certificate is from April 2014, so improvements made since then won't be reflected.
Held since March 2009 — that's 17 years off the open market, well above the local norm. That sale fell during the post-crash dip, which often skews comparisons against later neighbouring sales. Today's modelled estimate of £157,000 sits 65.3% above the 2009 sale of £95,000.
