About Llwyncelyn
Llwyncelyn is a detached house in Carmarthen (SA33 6AD). It has a recorded floor area of 132 m² (around 1423 sq ft), construction records dating it to before 1900 and council tax band D. The latest certificate (February 2009) shows an F (score 28), near the bottom of the EPC scale. The recommended improvements would push it to E (score 40). Main heating runs on oil.
