About 7 St Helens Avenue
7 St Helens Avenue is a six-bedroom mid-terrace house in Swansea (SA1 4ND). It has a recorded floor area of 154 m² (around 1658 sq ft), construction records dating it to 1900-1929 and council tax band E. The latest certificate (December 2022) shows a D (score 64), on the cusp of jumping into the C band. When first surveyed in August 2012 the rating was E, the property has climbed 1 band since. Between certificates, roof efficiency went from Average to Good and lighting went from Average to Very Good. The recommended improvements would lift it to B (score 84), a 2-band jump.
It hasn't traded since September 1997, a hold of 29 years that's notably long for the area.
