21 Welby Road, Birmingham, B28 8HP

21 Welby Road is a three-bedroom semi-detached house in Birmingham (B28 8HP). It has a recorded floor area of 186 m² (around 2002 sq ft), construction records dating it to 1930-1949 and council tax band C. The latest certificate (July 2015) shows an E (score 46), well below the UK norm with real room to improve. When first surveyed in September 2009 the rating was F, the property has climbed 1 band since. Between certificates, window efficiency went from Very Poor to Average, hot-water efficiency went from Very Poor to Good and main heating went from Average to Good; while roof efficiency dropped from Average to Very Poor and lighting dropped from Average to Very Poor. The recommended improvements would lift it to C (score 75), a 2-band jump. The latest certificate is from July 2015, so improvements made since then won't be reflected. Records show the property has been extended at some point in its history.

Untraded for 16 years, with the last transfer in February 2010. At 186 m² the property is well over the postcode median (86 m² across 34 EPCs), placing it in the larger end of the local stock. On energy efficiency it sits in the bottom 10% of properties in this postcode — significant headroom for improvement. Across 1996–2010, sale prices on this property compounded at 8.5% per year. Today's modelled estimate of £304,000 sits 85.4% above the 2010 sale of £164,000. On a £-per-square-foot basis, the last sale (£82/sq ft) was about 65.4% below the postcode norm. One planning record on file: an extension approved in 2010. Past consents include an extension, meaningful when judging how the property has evolved.
