About 2a
2a is a three-bedroom semi-detached house in Llandaff, Cardiff, Cardiff (CF5 2LQ). It has a recorded floor area of 135 m² (around 1453 sq ft), construction records dating it to 1900-1929 and council tax band H. The latest certificate (April 2026) shows a C (score 73). When first surveyed in January 2010 the rating was F, the property has climbed 3 bands since. Between certificates, wall efficiency went from Very Poor to Good, roof efficiency went from Very Poor to Very Good and window efficiency went from Very Poor to Poor. This certificate was lodged in the last six months, so the rating reflects current condition.
