12 Wellington House, Wellington Street, Swindon, SN1 1EB

12 Wellington House is a one-bedroom detached house in Swindon (SN1 1EB). It has a recorded floor area of 45 m² (around 484 sq ft), construction records dating it to 2007-2011 and council tax band A. The latest certificate (March 2026) returns a B (score 84), comfortably above the UK average. When first surveyed in June 2009 the rating was C, the property has climbed 1 band since. Between certificates, hot-water efficiency went from Poor to Average; while main heating dropped from Average to Poor. Main heating runs on electricity. This certificate was lodged in the last six months, so the rating reflects current condition. At 45 m² this is the 21st smallest of 60 units on EPC record in the building, where floor areas span 29–64 m². The building's EPC ratings span D to B, with this unit at the top.

Today's modelled estimate of £111,000 is 14.5% below the 2007 sale of £129,800, running counter to the wider postcode trend, which makes the EPC and condition history especially worth a look. On a £-per-square-foot basis, the last sale (£268/sq ft) was about 38.2% above the typical sold price in the postcode. It hasn't traded since August 2007, a hold of 19 years that's notably long for the area. That sale landed at the peak of the pre-credit-crunch market, which is a useful reference point when interpreting the price. Its energy rating outperforms most of the postcode (better than 73% of similar EPCs).
