23 Thornton Street, Halifax, HX1 3SD

23 Thornton Street is a two-bedroom mid-terrace house in Halifax (HX1 3SD). It has a recorded floor area of 103 m² (around 1109 sq ft), construction records dating it to before 1900 and council tax band A. The latest certificate (February 2015) shows an E (score 51), 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, hot-water efficiency went from Average to Good, lighting went from Poor to Very Good and main heating went from Very Poor to Good; while roof efficiency dropped from Average to Very Poor and window efficiency dropped from Good to Average. The recommended improvements would lift it to C (score 75), a 2-band jump. The latest certificate is from February 2015, so improvements made since then won't be reflected.

Untraded for 17 years, with the last transfer in January 2010. At 103 m² the property is well over the postcode median (78 m² across 21 EPCs), placing it in the larger end of the local stock. Across 2003–2010, sale prices on this property compounded at 9.3% per year. Today's modelled estimate of £106,000 sits 55.9% above the 2010 sale of £68,000. One planning record on file: an extension approved in 2017. Past consents include an extension, meaningful when judging how the property has evolved.
