About 23a
23a is a one-bedroom mid-terrace house in Luton (LU1 2NA). It has a recorded floor area of 47 m² (around 506 sq ft) and construction records dating it to before 1900. The latest certificate (October 2017) shows an E (score 47), well below the UK norm with real room to improve. The recommended improvements would lift it to C (score 72), a 2-band jump.
It hasn't traded since February 2008, a hold of 18 years that's notably long for the area. That sale landed at the peak of the pre-credit-crunch market, which is a useful reference point when interpreting the price. On energy efficiency it sits in the bottom 10% of properties in this postcode — significant headroom for improvement. 9 planning records sit against the property, 6 approved, 2 refused. Past consents include a loft conversion, meaningful when judging how the property has evolved.
