About 21 Bryn Syfi Terrace
A plain-English summary derived from public records, EPC certificates, sold prices and local data.
21 Bryn Syfi Terrace is a three-bedroom mid-terrace house in Swansea (SA1 6XN). It has a recorded floor area of 96 m² (around 1033 sq ft), construction records dating it to 1900-1929 and council tax band B. The latest certificate (April 2026) shows a C (score 69), just inside the C band. When first surveyed in May 2009 the rating was D, the property has climbed 1 band since. Between certificates, roof efficiency went from Very Poor to Very Good; while window efficiency dropped from Average to Poor. The recommended improvements would push it to B (score 84). This certificate was lodged in the last six months, so the rating reflects current condition.
Untraded for 19 years, with the last transfer in February 2007. That sale landed at the peak of the pre-credit-crunch market, which is a useful reference point when interpreting the price. Its energy rating outperforms most of the postcode (better than 86% of similar EPCs). Today's modelled estimate of £131,000 is 31% above the 2007 sale price.
