About 23 Diamond Street
23 Diamond Street is a three-bedroom mid-terrace house in King's Lynn (PE30 5LX). It has a recorded floor area of 75 m² (around 807 sq ft), construction records dating it to 1900-1929 and council tax band A. The latest certificate (November 2019) shows a D (score 66), on the cusp of jumping into the C band. The rating has held steady at D across 2 certificates since June 2009. Between certificates, roof efficiency went from Very Poor to Average and lighting went from Poor to Very Good; while hot-water efficiency dropped from Very Good to Good and main heating dropped from Very Good to Good. The recommended improvements would lift it to B (score 85), a 2-band jump.
Held since November 1997 — that's 29 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. Today's modelled estimate of £135,000 sits 366.3% above the 1997 sale of £28,950.
