About 27 Janson Road
27 Janson Road is a three-bedroom detached house in Southampton (SO15 5FU). It has a recorded floor area of 134 m² (around 1442 sq ft), construction records dating it to 1900-1929 and council tax band E. The latest certificate (September 2015) shows an F (score 38), near the bottom of the EPC scale. The recommended improvements would lift it to C (score 72), a 3-band jump. The latest certificate is from September 2015, so improvements made since then won't be reflected. Other recorded features include outbuildings. Period features are noted in the property record.
