20 Dumbleton Road is a two-bedroom semi-detached house in Killamarsh, Sheffield, Sheffield (S21 1AX). It has a recorded floor area of 62 m² (around 667 sq ft), construction records dating it to 1900-1929 and council tax band A. The latest certificate (August 2014) shows a D (score 61), on the cusp of jumping into the C band. When first surveyed in July 2014 the rating was E, the property has climbed 1 band since. Between certificates, wall efficiency went from Poor to Good. The recommended improvements would push it to C (score 80). The latest certificate is from August 2014, so improvements made since then won't be reflected. The home occupies a corner plot.
It hasn't traded since April 2008, a hold of 18 years that's notably long for the area.
