1a, New Road, Welwyn, AL6 0AE
About 1a
1a is a five-bedroom semi-detached house in Welwyn (AL6 0AE). It has a recorded floor area of 189 m² (around 2034 sq ft), construction records dating it to 2003-2006 and council tax band G. The latest certificate (January 2023) shows a C (score 75), near the top of the C band. The rating has held steady at C across 8 certificates since December 2008. Between certificates, lighting dropped from Good to Average. The recommended improvements would push it to B (score 85).
Held since September 2007 — that's 19 years off the open market, well above the local norm. That sale landed at the peak of the pre-credit-crunch market, which is a useful reference point when interpreting the price. Today's modelled estimate of £928,000 sits 52.1% above the 2007 sale of £610,000. On a £-per-square-foot basis, the last sale (£300/sq ft) was about 21% below the postcode norm. One planning record on file: an extension approved in 2009. Past consents include an extension and a porch, meaningful when judging how the property has evolved.
