18 Deeneside is a four-bedroom detached house in Weldon, Corby, Corby (NN17 3HQ). It has a recorded floor area of 160 m² (around 1722 sq ft), construction records dating it to 1930-1949 and council tax band C. The latest certificate (March 2016) shows an E (score 53), well below the UK norm with real room to improve. Earlier certificates rated it D (October 2010); the latest reading is one band lower. Between certificates, roof efficiency dropped from Good to Average and lighting dropped from Very Good to Good. The recommended improvements would lift it to C (score 77), a 2-band jump. The latest certificate is from March 2016, so improvements made since then won't be reflected.
Held since April 1998 — that's 28 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. At 160 m² the property is well over the postcode median (88 m² across 9 EPCs), placing it in the larger end of the local stock. It lags the bulk of the postcode on energy efficiency (less efficient than 78% of similar EPCs). Today's modelled estimate of £368,000 sits 457.6% above the 1998 sale of £66,000. On a £-per-square-foot basis, the last sale (£38/sq ft) was about 75.1% below the postcode norm. 2 planning records sit against the property, 2 approved, 0 refused. Past consents include an extension, meaningful when judging how the property has evolved.
