108a, Commercial Road, Swindon, SN1 5PL

108a is a one-bedroom semi-detached house in Swindon (SN1 5PL). It has a recorded floor area of 38 m² (around 406 sq ft), construction records dating it to 1950-1966 and council tax band A. At 38 m² this is the smallest unit on EPC record across 108a (38–64 m²). The building's EPC ratings span F to E, with this unit at the bottom. The latest certificate (December 2010) shows an F (score 31), near the bottom of the EPC scale. The recommended improvements would lift it to C (score 69), a 3-band jump. Main heating runs on electricity. The latest certificate is from December 2010, so improvements made since then won't be reflected.

Today's modelled estimate of £162,000 is 12.7% below the 2009 sale of £185,500, a rare downward gap that often correlates with deferred maintenance or unfinished works. On a £-per-square-foot basis, the last sale (£457/sq ft) was about 41.2% above the typical sold price in the postcode. Untraded for 17 years, with the last transfer in October 2009. That sale fell during the post-crash dip, which often skews comparisons against later neighbouring sales. It lags the bulk of the postcode on energy efficiency (less efficient than 87% of similar EPCs).
