Get started12 Christopher Street is a three-bedroom mid-terrace house in Llanelli (SA15 1DF). It has a recorded floor area of 79 m² (around 850 sq ft), construction records dating it to 1900-1929 and council tax band B. The latest certificate (January 2026) shows a D (score 63), on the cusp of jumping into the C band. The rating has held steady at D across 3 certificates since April 2009. Between certificates, roof efficiency went from Average to Good, window efficiency went from Poor to Average and lighting went from Poor to Good. The recommended improvements would push it to C (score 80). This certificate was lodged in the last six months, so the rating reflects current condition.
It hasn't traded since September 2007, a hold of 19 years that's notably long for the area. That sale landed at the peak of the pre-credit-crunch market, which is a useful reference point when interpreting the price. Today's modelled estimate of £108,000 is 20% above the 2007 sale price. On a £-per-square-foot basis, the last sale (£106/sq ft) was about 62.7% above the typical sold price in the postcode. At 79 m² it's 18.1% smaller than the typical home in the postcode (97 m² median across 22 EPCs).
The EPC has just been inspected, so the rating reflects current condition.
