About 11 Russell Street
11 Russell Street is a mid-terrace house in Swansea (SA1 4HR). It has a recorded floor area of 221 m² (around 2379 sq ft), construction records dating it to before 1900 and council tax band E. The latest certificate (December 2025) shows a C (score 78), near the top of the C band. When first surveyed in October 2022 the rating was E, the property has climbed 2 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 Average to Good; while hot-water efficiency dropped from Good to Average. The recommended improvements would push it to B (score 81). Main heating runs on electricity. This certificate was lodged in the last six months, so the rating reflects current condition.
