3 Mardale Close is a three-bedroom detached house in Nine Elms, Swindon, Swindon (SN5 5UT). It has a recorded floor area of 111 m² (around 1194 sq ft), construction records dating it to 1983-1990 and council tax band D. The latest certificate (February 2009) shows an E (score 49), well below the UK norm with real room to improve. The recommended improvements would lift it to C (score 71), a 2-band jump. The latest certificate is from February 2009, so improvements made since then won't be reflected.

Held since August 2009 — that's 17 years off the open market, well above the local norm. That sale fell during the post-crash dip, which often skews comparisons against later neighbouring sales. Across 2004–2009, sale prices on this property compounded at 2.2% per year. Today's modelled estimate of £333,000 sits 73.4% above the 2009 sale of £192,000. One planning record on file: an extension approved in 2007. Past consents include an extension and a conservatory, meaningful when judging how the property has evolved. It lags the bulk of the postcode on energy efficiency (less efficient than 83% of similar EPCs).
