22 Guise Lane is a three-bedroom end-of-terrace house in Bassingbourn, Royston, Royston (SG8 5PJ). It has a recorded floor area of 61 m² (around 657 sq ft), construction records dating it to 1991-1995 and council tax band D. The latest certificate (December 2024) shows an E (score 52), well below the UK norm with real room to improve. When first surveyed in October 2008 the rating was F, the property has climbed 1 band since. Between certificates, wall efficiency went from Poor to Good, roof efficiency went from Poor to Good and window efficiency went from Average to Good; while main heating dropped from Poor to Very Poor. The recommended improvements would lift it to B (score 86), a 3-band jump. Main heating runs on electricity. The home occupies a cul-de-sac position.
Held since June 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. Today's modelled estimate of £322,000 sits 92.2% above the 2009 sale of £167,500. At 61 m² it sits well below the postcode median (135 m² across 11 EPCs), making it one of the more compact homes locally.
