Rockett House, School Lane, Holmpton, Withernsea, HU19 2QS

Rockett House is a detached house in Holmpton, Withernsea, Withernsea (HU19 2QS). It has a recorded floor area of 174 m² (around 1873 sq ft), construction records dating it to before 1900 and council tax band C. The latest certificate (January 2013) shows a D (score 61), on the cusp of jumping into the C band. When first surveyed in May 2009 the rating was E, the property has climbed 1 band since. Between certificates, roof efficiency went from Average to Very Good and lighting went from Poor to Very Good; while window efficiency dropped from Good to Average. The recommended improvements would lift it to B (score 87), a 2-band jump. Main heating runs on oil. The latest certificate is from January 2013, so improvements made since then won't be reflected.

It hasn't traded since July 2009, a hold of 17 years that's notably long for the area. That sale fell during the post-crash dip, which often skews comparisons against later neighbouring sales. At 174 m² the property is well over the postcode median (128 m² across 14 EPCs), placing it in the larger end of the local stock. Today's modelled estimate of £303,000 is 37.1% above the 2009 sale price. On a £-per-square-foot basis, the last sale (£118/sq ft) was about 15.6% below the postcode norm.
