About 18 Castle Mews
18 Castle Mews is a one-bedroom mid-terrace house in Wellingborough (NN8 1NX). It has a recorded floor area of 36 m² (around 388 sq ft), construction records dating it to 1983-1990 and council tax band A. The latest certificate (September 2024) shows a D (score 66), on the cusp of jumping into the C band. Earlier certificates rated it C (December 2008); the latest reading is one band lower. Between certificates, window efficiency dropped from Good to Average and main heating dropped from Poor to Very Poor. The recommended improvements would lift it to B (score 84), a 2-band jump. Main heating runs on electricity. At 36 m² this is the 3rd smallest of 20 units on EPC record in the building, where floor areas span 35–55 m². The building's EPC ratings span E to C across 20 units on file.
It hasn't traded since January 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. Across 1997–2009, sale prices on this property compounded at 8.1% per year. Today's modelled estimate of £101,000 sits 62.9% above the 2009 sale of £62,000. On a £-per-square-foot basis, the last sale (£160/sq ft) was about 23% above the typical sold price in the postcode. At 36 m² it's 23.4% 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.
