About 25 Clos Helyg
A plain-English summary derived from public records, EPC certificates, sold prices and local data.
25 Clos Helyg is a semi-detached house in Gowerton, Swansea, Swansea (SA4 3GH). It has a recorded floor area of 77 m² (around 829 sq ft), construction records dating it to 1996-2002 and council tax band D. The latest certificate (May 2013) shows a D (score 64), on the cusp of jumping into the C band. The recommended improvements would lift it to B (score 83), a 2-band jump. The latest certificate is from May 2013, so improvements made since then won't be reflected.
At 77 m² the property is well over the postcode median (56 m² across 17 EPCs), placing it in the larger end of the local stock. Across 1999–2014, sale prices on this property compounded at 4.8% per year. Today's modelled estimate of £254,000 sits 81.4% above the 2014 sale of £140,000. On a £-per-square-foot basis, the last sale (£169/sq ft) was about 57.9% above the typical sold price in the postcode. Last sold in February 2014, so it's been off the market for around 13 years.
