22 Delius Close is a four-bedroom detached house in Blackburn (BB2 3WS). It has a recorded floor area of 144 m² (around 1550 sq ft), construction records dating it to 1967-1975 and council tax band E. The latest certificate (January 2015) shows an E (score 53), well below the UK norm with real room to improve. Earlier certificates rated it C (November 2008); the latest reading is 2 bands lower. Between certificates, wall efficiency dropped from Very Good to Poor and roof efficiency dropped from Very Good to Average. The recommended improvements would lift it to B (score 83), a 3-band jump. The latest certificate is from January 2015, so improvements made since then won't be reflected. Our model identifies extension potential, subject to local planning policy. The home occupies a cul-de-sac position.

It hasn't traded since December 2008, a hold of 17 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. At 144 m² the property is well over the postcode median (91 m² across 20 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. Today's modelled estimate of £312,000 is 31.1% above the 2008 sale price. On a £-per-square-foot basis, the last sale (£154/sq ft) was about 17.9% above the typical sold price in the postcode.
