20 Castle Mews is a one-bedroom semi-detached house in Wellingborough (NN8 1NX). It has a recorded floor area of 35 m² (around 377 sq ft), construction records dating it to 1983-1990 and council tax band A. At 35 m² this is the smallest unit on EPC record across the building (35–55 m²). The building's EPC ratings span E to C, with this unit at the top. The latest certificate (December 2022) shows a C (score 69), just inside the C band. The rating has held steady at C across 2 certificates since October 2008. Between certificates, window efficiency went from Very Poor to Good and main heating went from Poor to Average; while roof efficiency dropped from Good to Average and hot-water efficiency dropped from Average to Very Poor. The recommended improvements would push it to B (score 81). Main heating runs on electricity.
Untraded for 19 years, with the last transfer in November 2007. That sale landed at the peak of the pre-credit-crunch market, which is a useful reference point when interpreting the price. Today's modelled estimate of £99,000 sits 98% above the 2007 sale of £50,000. At 35 m² it's 25.5% smaller than the typical home in the postcode (47 m² median across 19 EPCs). 1 bedrooms is on the smaller side for this postcode, where 3 is the typical count.
