20 Heol Cennen is a four-bedroom semi-detached house in Ffairfach, Llandeilo, Llandeilo (SA19 6UH). It has a recorded floor area of 142 m² (around 1528 sq ft), construction records dating it to 1900-1929 and council tax band D. The latest certificate (April 2016) shows an F (score 35), near the bottom of the EPC scale. The recommended improvements would lift it to C (score 79), a 3-band jump.
