About 18 Boleyn Close
A plain-English summary derived from public records, EPC certificates, sold prices and local data.
18 Boleyn Close is a detached house in Grange Park, Swindon, Swindon (SN5 6JZ). It has a recorded floor area of 132 m² (around 1421 sq ft), construction records dating it to 1976-1982 and council tax band E. The latest certificate (January 2014) shows a D (score 66), on the cusp of jumping into the C band. The recommended improvements would lift it to B (score 84), a 2-band jump. The latest certificate is from January 2014, so improvements made since then won't be reflected.
It hasn't traded since December 1995, a hold of 31 years that's notably long for the area. Only one transfer is on record with HM Land Registry, suggesting it has stayed in the same hands for a long time. Today's modelled estimate of £417,000 sits 320.2% above the 1995 sale of £99,250. On a £-per-square-foot basis, the last sale (£70/sq ft) was about 54.3% below the postcode norm. One planning record on file: an extension approved in 2016. Past consents include an extension, meaningful when judging how the property has evolved.
