About 73 Warren Way
73 Warren Way is a semi-detached house in Welwyn (AL6 0DL). It has a recorded floor area of 91 m² (around 974 sq ft), construction records dating it to 1950-1966 and council tax band D. The latest certificate (April 2009) shows an E (score 51), 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 April 2009, so improvements made since then won't be reflected.
It hasn't traded since August 2009, a hold of 17 years that's notably long for the area. That sale fell during the post-crash dip, which often skews comparisons against later neighbouring sales. Today's modelled estimate of £528,000 sits 76% above the 2009 sale of £300,000. 2 planning records sit against the property, 2 approved, 0 refused. Past consents include an extension, meaningful when judging how the property has evolved. At 91 m² it's 24.6% smaller than the typical home in the postcode (120 m² median across 19 EPCs). It lags the bulk of the postcode on energy efficiency (less efficient than 74% of similar EPCs).
