About 11 Birch Grove
11 Birch Grove is a four-bedroom semi-detached house in Welwyn (AL6 0QP). It has a recorded floor area of 100 m² (around 1076 sq ft), construction records dating it to 1983-1990 and council tax band E. The latest certificate (May 2018) shows a D (score 63), on the cusp of jumping into the C band. The rating has held steady at D across 2 certificates since March 2015. Between certificates, roof efficiency went from Poor to Very Good and lighting went from Good to Very Good; while window efficiency dropped from Good to Average. The recommended improvements would push it to C (score 80). Other recorded features include a conservatory.
Held since December 1995 — that's 30 years off the open market, well above the local norm. Only one transfer is on record with HM Land Registry, suggesting it has stayed in the same hands for a long time. Today's modelled estimate of £552,000 sits 392.9% above the 1995 sale of £112,000. On a £-per-square-foot basis, the last sale (£104/sq ft) was about 64.8% below the postcode norm. One planning record on file: tree works approved in 2022. Past consents include tree works, meaningful when judging how the property has evolved.
