About 4 Diamond Street
4 Diamond Street is a two-bedroom mid-terrace house in King's Lynn (PE30 5LX). It has a recorded floor area of 74 m² (around 797 sq ft), construction records dating it to 1900-1929 and council tax band A. The latest certificate (February 2020) shows a D (score 63), on the cusp of jumping into the C band. When first surveyed in May 2010 the rating was F, the property has climbed 2 bands since. Between certificates, window efficiency went from Very Poor to Good, hot-water efficiency went from Average to Good and main heating went from Average to Good.
