About 11 Clyndu Street
11 Clyndu Street is a semi-detached house in Morriston, Swansea, Swansea (SA6 7BQ). It has a recorded floor area of 99 m² (around 1066 sq ft), construction records dating it to before 1900 and council tax band B. The latest certificate (November 2014) shows an F (score 33), near the bottom of the EPC scale. The rating has held steady at F across 2 certificates since January 2014. Between certificates, roof efficiency went from Very Poor to Average and hot-water efficiency went from Very Poor to Poor. The recommended improvements would lift it to B (score 81), a 4-band jump. The latest certificate is from November 2014, so improvements made since then won't be reflected.
Untraded for 26 years, with the last transfer in September 2000. Only one transfer is on record with HM Land Registry, suggesting it has stayed in the same hands for a long time. At 99 m² the property is well over the postcode median (76 m² across 8 EPCs), placing it in the larger end of the local stock. On energy efficiency it sits in the bottom 10% of properties in this postcode — significant headroom for improvement. Today's modelled estimate of £134,000 sits 213.5% above the 2000 sale of £42,750.
