About 12a
12a is a three-bedroom semi-detached house in Leigh On Sea (SS9 1AX). It has a recorded floor area of 126 m² (around 1356 sq ft), construction records dating it to 1900-1929 and council tax band D. The latest certificate (April 2025) shows an E (score 51), well below the UK norm with real room to improve. The recommended improvements would lift it to C (score 71), a 2-band jump.
It hasn't traded since October 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. At 126 m² the property is well over the postcode median (74 m² across 22 EPCs), placing it in the larger end of the local stock. Across 1997–2009, sale prices on this property compounded at 11.9% per year. Today's modelled estimate of £585,000 sits 72.1% above the 2009 sale of £340,000.
